│ The landscape of the WEB scene has changed in the last four years.           │
│ Subsequently, the ability to defeat DRM has become ubiquitous.               │
│ What were once rules written around the assumption that capturing and        │
│ transcoding would be more commonplace than lossless downloading have         │
│ naturally become increasingly out of date.                                   │
│                                                                              │
│ HDTV is still slowly, but surely, being replaced by WEB. Not just in         │
│ quality, but with more and more providers transitioning to streaming at      │
│ airtime, and some even putting entire seasons up days/weeks before airtime.  │
│                                                                              │
│ Transcoding only for crop has become a burden, and only serves to damage the │
│ section.                                                                     │
│ Internals have been abused with rampant technical flaws, lesser quality and  │
│ identical files.                                                             │
│ While UHD and HDR streams were but an afterthought four years ago, they have │
│ now become a daily occurrence with groups left unsure of how to release      │
│ them.                                                                        │

│ Worst of all, with an almost endless array of web sources available          │
│ simultaneously, groups continuously pick the first to appear, which, more    │
│ often than not, is the worst possible quality.                               │
│                                                                              │
│ This update will address all these issues and more, by taking one large leap │
│ forward and no steps back.                                                   │

│ Rules listed under untouched or transcoded labelled sections only apply to   │
│ releases of that type and supersede any similar rule mentioned elsewhere.    │
│ e.g. Rule 8.1 defines SD as resolutions with a maximum horizontal display of │
│ 720 pixels, unless the release is considered untouched, in which case rule   │
│ 1.6 applies.                                                                 │

│     1.1) Untouched releases must be considered as anything that has been     │
│          losslessly downloaded by official (offered) or unofficial           │
│          (backdoor) methods.                                                 │
│         1.1.1) Untouched video streams must be in the H.264/MPEG-4 AVC or    │
│                H.265/HEVC codec. See exception in 1.5.1.                     │
│     1.2) Source video and audio streams must be left as obtained from the    │
│          source.                                                             │
│     1.3) Untouched video streams with, and without, x264/x265 headers must   │
│          be tagged as WEB.H264 and WEB.H265 respectively.                    │
│         1.3.1) HEVC/H265 may only be used when the source does not offer a   │
│                H264 stream in situations it is used any untouched sections   │
│                referring to H264/x264 must be considered as H265/x265.       │
│     1.4) Transcoding untouched files must only occur if files do not meet    │
│          the standards and specifications listed in this section, and must   │
│          only be a last resort.                                              │
│         1.4.1) Any transcoding of untouched files must follow the            │
│                transcoding standards - see sections marked as 'Transcoded'.  │
│         1.4.2) Transcoding must be done from files of the highest resolution │
│                and bitrate offered.                                          │
│             1.4.2.1) 720p/1080p and 1080p/2160p streams are considered of    │
│                      equal value, unless DRM protection levels of            │
│                      1080p/2160p are laxed to 720p levels.                   │
│                          e.g. 2160p is protected at the same laxed level as  │
│                          720p.                                               │
│                              e.g. 1080p is protected at the same laxed level │
│                              as 720p.                                        │
│         1.4.3) Transcoding may occur when correcting a technical flaw.       │
│                    e.g. Decimating a source with duplicates every 5th frame. │
│         1.4.4) In situations where a target resolution is not offered by any │
│                lossless source, or the resolution offered by any source does │
│                not meet the minimum resolution requirements, transcoding     │
│                from the highest resolution and bitrate offered is allowed.   │
│                However, if at least one source can provide the correct       │
│                resolution, transcoding is not allowed.                       │
│                    e.g. If 1080p and 720p can be retrieved from multiple     │
│                    sources, but SD cannot be retrieved from any source,      │
│                    transcoding the 1080p to SD is allowed.                   │
│         1.4.5) If the untouched file does not contain any technical flaws    │
│                and meets the minimum standards required, transcoding to      │
│                create any WEBRip is not allowed.                             │
│                    e.g. 1080p.WEB.H264 -> 720p.WEBRip.x264.                  │
│             1.4.5.1) When transcoding video for a valid reason, audio must   │
│                      not be transcoded unless necessary and be included as   │
│                      is and vice versa.                                      │
│                          e.g. Video contains dupes and must be decimated,    │
│                          audio is fine. Video must be re-encoded but the     │
│                          audio must be included as is.                       │
│                 1.4.5.1.1) Except for SD audio which must either be an       │
│                            untouched track respecting rule 2.2 or a          │
│                            transcoded track from the highest quality audio   │
│                            track respecting rule 5.6.2.                      │
│     1.5) Untouched video streams which do not use an AVC or HEVC codec must  │
│          be transcoded and follow the transcoding standards, see section 3.  │
│         1.5.1) Except in very rare cases VP9/AV1 may be used, only when the  │
│                source does not offer a H264/H265 stream.                     │
│             1.5.1.1) Any untouched sections referring to H264/x264 must be   │
│                      considered as VP9 or AV1.                               │
│             1.5.1.2) Transcoding from either of these codecs, except when    │
│                      correcting technical flaws, is not allowed.             │
│     1.6) Standard definition (SD) refers to a resolution with a horizontal   │
│          minimum of 720 pixels, or a resolution which does not exceed the    │
│          specifications of 720p, see rule 8.2.                               │
│         1.6.1) If all sources provide standard definition resolutions which  │
│                fall below the above minimum, transcoding from the highest    │
│                available resolution is allowed, see rule 1.4.4.              │
│         1.6.2) Except in situations where only one source has the file on    │
│                offer at a specific resolution. If the resolution of the file │
│                falls below the above minimum, the file may still be          │
│                released. However, the NFO must state why the resolution does │
│                not meet the minimum.                                         │
│     1.7) In rare cases, a resolution exceeding the specifications outlined   │
│          in rules 1.6, 8.2, 8.3 and 8.4 is allowed when the only available   │
│          stream offered for the target resolution exceeds limitations due to │
│          a reasonable circumstance.                                          │
│              e.g. Streaming provider offers 720p only at 1392x660 due        │
│              maintaining AR while offering a cropped stream.                 │
│         1.7.1) The NFO must state why the resolution exceeds the maximum.    │
│     1.8) Must use the highest available bitrate offered by the source for    │
│          that resolution.                                                    │
│              e.g. Releasing a 720p at 4,000 Kbps bitrate, when a 720p at     │
│              8,000 Kbps bitrate is offered is not allowed.                   │
│     1.9) Retaining black borders (i.e. needs cropping) is not a technical    │
│          flaw. Transcoding only to perform cropping is not allowed.          │
│         1.9.1) Container level cropping is not allowed.                      │
│         1.9.2) When transcoding to fix another valid technical flaw (e.g.    │
│                decimating duplicates), cropping must be applied if           │
│                necessary.                                                    │
│     1.10) VFR (Variable Frame Rate) methods are allowed only if present in   │
│           the original source.                                               │
│         1.10.1) If CFR (Constant Frame Rate) can be used when remuxing and   │
│                 does not result in playback issue, CFR must be used.         │
│             1.10.1.1) FPS values stored in the video bitstream must be       │
│                       corrected when remuxing. MKVToolnix with '--fix-       │
│                       bitstream-timing-information' enabled is the           │
│                       recommended method.                                    │
│     1.11) Trimming unrelated footage (see rule 7.7) must be done losslessly  │
│           via keyframe intervals (GOP). MKVToolnix is the recommended tool.  │
│         1.11.1) If unrelated footage cannot be removed via this method,      │
│                 transcoding a maximum of one GOP per cut point is allowed    │
│                 and the release must still be tagged WEB. VideoRedo is the   │
│                 recommended tool.                                            │
│     1.12) Incorrect pixel aspect ratio (PAR), or a non-square sample aspect  │
│           ratio (SAR), must be fixed using the correct display aspect ratio  │
│           (DAR) set at a container level (--aspect-ratio). MKVToolnix is the │
│           recommended tool.                                                  │
│               e.g. A video stream with a non-square SAR must specify the     │
│               correct DAR when muxing.                                       │
│     1.13) Releases with a non-square SAR are not considered technically      │
│           flawed.                                                            │
│         1.13.1) However, a source which provides files with a square SAR     │
│                 will trump an equivalent file with a non-square SAR. It is   │
│                 recommended to use a source which provides files with a      │
│                 square SAR.                                                  │
│         1.13.2) In situations where a source initially provides a non-square │
│                 SAR file and later updates with a square SAR file, the       │
│                 initial release with a non-square SAR is considered of lower │
│                 quality and a technical flaw.                                │
│                     e.g. Release A: 960x720, SAR: 4:3, DAR: 16:9.            │
│                     Release B: 1280x720, SAR: 1:1, DAR: 16:9.                │
│                     Both releases are considered as 720p.                    │
│                     If Release A is first: Release A remains unnuked and is  │
│                     a valid release until Release B is released. Release B   │
│                     then propers Release A.                                  │

│     2.1) Must use the original audio track offered by the source.            │
│     2.2) Standard definition releases must only contain an audio track with  │
│          a maximum of 2.0 channels.                                          │
│         2.2.1) Except where the only available audio track on offer contains │
│                more than 2.0 channels. The NFO must mention why an audio     │
│                track with more than 2.0 channels was used.                   │
│         2.2.2) In situations where a source provides two audio tracks, a 2.0 │
│                and 5.1 track, the 2.0 audio track must be used.              │
│         2.2.3) If a source provides identical channel audio tracks using two │
│                different codecs, it is at the discretion of the group which  │
│                track is used. It is recommended to use the smaller file.     │
│                    e.g. A source offers AC3 2.0 and AAC 2.0, the group may   │
│                    choose to remux the AC3 or AAC.                           │
│     2.3) High Definition releases must use the highest available audio       │
│          format and quality offered by the source.                           │
│         2.3.1) Highest quality must determined by all characteristics of an  │
│                audio track in this order: positional metadata (e.g. Atmos),  │
│                channel count, codec and bitrate.                             │
│                    e.g. 576 Kbps, 5.1 E-AC3 w/ Atmos > 640 Kbps, 5.1 AC3 >   │
│                    2.0 E-AC3.                                                │
│                        e.g. 385 Kbps, 5.1 AC3 > 128 Kbps, 5.1 E-AC3          │
│                            e.g. 445 Kbps 5.1 AAC > 384 Kbps, 5.1 E-AC3       │
│         2.3.2) In situations where a lesser audio format is offered for      │
│                larger resolutions in comparison to lower resolutions, groups │
│                must use the highest available audio format from all          │
│                resolutions.                                                  │
│                    e.g. A source provides an AC3 5.1 track for SD            │
│                    resolutions, but an AAC 2.0 track for 720p/1080p. The AC3 │
│                    5.1 track must be used for 720p/1080p resolutions.        │
│         2.3.3) If using the highest available audio format results in a      │
│                technical flaw (e.g. sync issues or glitches), minor          │
│                adjustments to the audio track may be applied. If groups are  │
│                unable to correct any flaws, the original audio track must be │
│                used.                                                         │
│                                                                              │

│          captured or encoded by a group to a lesser format or quality        │
│          (lossy).                                                            │
│     3.2) Transcoded releases must be tagged as WEBRip.x264/x265.             │
│     3.3) Streams must be captured at the highest available resolution and    │
│          bitrate offered.                                                    │
│              e.g. Source offers 2160p, 1080p and 720p streams. Using         │
│              anything but the 2160p stream is not allowed.                   │
│         3.3.1) Streams must not have any degradation in quality throughout   │
│                the capture, and releases with drops to a lower resolution or │
│                bitrate is considered a technical flaw.                       │
│         3.3.2) Audio must be captured in the highest format offered by the   │
│                source stream, not what the capturing device is capable of.   │
│                This includes channel count and bitrate offered.              │
│                    e.g. If a Netflix show lists a 5.1 track, the resultant   │
│                    capture and release should also contain a 5.1 audio       │
│                    track.                                                    │
│     3.4) Captures should be done at the native broadcast framerate of the    │
│          source.                                                             │
│         3.4.1) Captures from devices which are unable to output a native     │
│                format must be restored to the original framerate.            │
│         3.4.2) If captures cannot be completely restored to their native     │
│                framerate, it is considered a technical flaw.                 │
│                    e.g. A single dupe frame every 1000 or blended/ghost      │
│                    frames due to mangling from the streaming device.         │
│     3.5) Captures should be done at the native colour space of the source    │
│          (e.g. YUV or RGB), and manual corrections should be made to achieve │
│          an output near-identical to the source.                             │
│     3.6) Capture software and hardware which introduces video cropping       │
│          greater than 2 pixels on any side is not allowed, and is considered │
│          a technical flaw.                                                   │
│     3.7) Final resolution must maintain the same aspect ratio as the source  │
│          after cropping and kept at mod 2.                                   │
│         3.7.1) Sources must have all black borders cropped to the widest     │
│                frame.                                                        │
│         3.7.2) The same aspect ratio as calculated from the source must be   │
│                used, see rule 8.12.                                          │
│     3.8) If the video is being transcoded from an untouched source (rule     │
│          1.4.4 and 1.4.5), the NFO must state the reason for transcoding.    │
│         3.8.1) If a technical flaw is present that is being rectified by     │
│                transcoding (rule 1.4.3), the flaw must also be included with │

│                bitrate, to account for HEVC's 40-50% improvement over AVC.   │
│                    e.g. Transcoding 2160p SDR with a bitrate of 15,000 Kbps  │

│     4.7) Use of 2-pass is accepted for all resolutions. However, this method │
│          should be used only in extreme cases and not as a primary           │
│          replacement for CRF methods. e.g. If the source contains an         │
│          excessive amount of grain or black and white scenes.                │
│         4.7.1) The NFO must provide sufficient detailed evidence of 2-pass   │

│                    e.g. Source has heavy grain throughout, which required    │
│                    the use of 2-pass to remain transparent at a reasonable   │
│                    bitrate. Included in the proof directory is test encodes  │
│                    of some troublesome areas at CRF and 2-pass showing a     │
│                    substantial improvement in quality at a more reasonable   │
│                    bitrate. CRF needs 6.5GB to stay transparent 2-pass only  │
│                    needed 4GB is detailed evidence.                          │
│                        e.g. The source was grainy so 2-pass was used is NOT  │
│                        detailed evidence.                                    │
│         4.7.2) Exceeding CRF 24 on any resolution is a good indication to    │
│                consider the use of 2-pass.                                   │
│         4.7.3) 2-pass encodes must follow the percentage values in 4.6, it   │
│                is recommended to target the maximum value allotted and work  │
│                down.                                                         │
│     4.8) Exceeding the percentage values in 4.6 is allowed, but very         │
│          detailed justification must be included in the NFO.                 │
│              e.g. 720p encoded at CRF 13 resulting in an encode 80% of the   │
│              source, this value was picked as the sourced content had a lot  │
│              of strobing effects (e.g. 1m10s-15m30s) and confetti scenes     │
│              (e.g. 20m55s-50m60s) which compressed poorly and required a     │
│              higher bitrate to maintain transparency. Proof directory        │
│              contains samples of these troublesome scenes at 30% and 50%     │
│              showing a substantial picture improvement.                      │
│     4.9) Using unreasonably high CRF values or low target bitrates with      │
│          2-pass for the source content is considered a technical flaw.       │
│              e.g. Producing a 1080p encode at 40% of the source bitrate,     │
│              offering no justification in the NFO and having poor            │
│              transparency to the source IS a technical flaw.                 │
│                  e.g. Producing a 1080p encode at 20% of the source bitrate  │
│                  (This may occur on animation content to avoid a bloated     │
│                  encode), offering justification in the NFO and having good  │
│                  transparency to the source is NOT a technical flaw.         │
│     4.10) Encoded video bitrate must not exceed the source video bitrate.    │
│         4.10.1) Video bitrate refers only to the bitrate for the video       │
│                 stream, and not the overall muxed bitrate of all streams     │
│                 within the container or the bitrate of a captured file.      │
│             4.10.1.1) Original video stream bitrate can be determined by     │
│                       observing network traffic during playback, or          │
│                       examining manifests/metadata of the encrypted video    │
│                       when capturing.                                        │
│         4.10.2) The following algorithm can also be used to estimate a CRF   │
│                 value if the value originally used results in a bitrate      │
│                 which exceeds the source's.                                  │

│         7.5.2) Sources with multiple episodes, parts etc., that are in a     │
│                single video file, must be split into individual releases if  │
│                there is a clear delineation between them, such as credits.   │
│                    e.g. Source contains 10 episodes in a single stream with  │
│                    all episodes strung together with credits between every   │

│                    e.g. Only the credits are interlaced, you may leave them  │
│                    interlaced or only apply a deinterlacer to the credits,   │
│                    not the entire video.                                     │

│                movie title, closing credits.                                 │
│         7.8.3) For sources where relevant on-screen information is included  │
│                in the form of English subtitles instead of overlays, these   │
│                subtitles must be included as a forced track (see 11.2). If   │
│                the source does not include them in English, it is not        │
│                allowed to omit them and release the feature without them, as │
│                it is still considered relevant information.                  │
│     7.9) Using multiple web based video sources of the same feature is       │
│          allowed and must not be encoded separately. Each source and what    │
│          content came from which must be noted in the NFO.                   │

│                      frame.                                                  │
│             8.8.2.2) Releases which include faded edges must consider faded  │
│                      edges as a valid part of the video frame and do not     │
│                      count as black borders.                                 │
│                          e.g. A release cannot be propered if 1 pixel of     │
│                          faded edges and 1 pixel of black exists.            │
│         8.8.3) In the case of varying aspect ratios throughout the feature,  │
│                video must be cropped to the widest frame.                    │
│             8.8.3.1) Studio logos and credits must be disregarded when       │
│                      determining the widest frame.                           │
│         8.8.4) Situations where video cropping of the same content varies    │
│                between sources are not considered a technical flaw, and may  │
│                not be propered.                                              │
│     8.9) Video can be over or under-cropped by a maximum of 1 pixel per      │
│          side. Over or under-cropping by more than 1 pixel per side is       │
│          considered a technical flaw.                                        │
│         8.9.1) Under-crop refers to portions of the video frame which is not │
│                part of the feature.                                          │
│     8.10) Resolution must be within 0.2% of the original aspect ratio.       │
│         8.10.1) The original aspect ratio must only be calculated from the   │
│                 source after cropping.                                       │
│         8.10.2) In situations where the source aspect ratio is incorrect as  │
│                 a result of bad mastering, a source sample and comparison    │
│                 screenshot of the final aspect ratio must be included.       │
│     8.11) Sample aspect ratio (SAR):                                         │

│           CropRight]) / (SourceHeight - [CropTop + CropBottom])]             │
│           The correct mod2 value can also be calculated from the ceiling of  │
│           TargetHeight if the value is odd, and the floor of TargetHeight if │
│           the value is even.                                                 │

│                 The TargetHeight value (HeightA or HeightB) which results in │
│                 an aspect ratio error which tends to zero must be used.      │
│                     e.g. TargetWidth: 1280.                                  │
│                     SourceWidth: 1920, SourceHeight: 1080.                   │
│                     CropLeft + CropRight = 0, CropTop + CropBottom = 4.      │
│                     TargetHeight = 1280 / ((1920 - 0) / (1080 - 4)) or       │
│                     717.33.                                                  │
│                     HeightA = floor(717.33 + (717.33 mod2)) or 718.          │
│                     HeightB = floor(717.33 - (717.33 mod2)) or 716.          │
│                     TargetWidth x HeightA = 1280x718 with -0.09% AR error.   │
│                     TargetWidth x HeightB = 1280x716 with 0.19% AR error.    │
│                     -0.09% tends closer to zero than 0.19% does (0.09 <      │
│                     0.19), therefore, HeightA must be used.                  │
│                                                                              │
│ 9) [ Common: Framerate ]                                                     │
│     9.1) Constant frame rate (CFR) must be used.                             │
│         9.1.1) Variable frame rate (VFR) methods are not allowed.            │
│     9.2) Dupes based on frame rate are not allowed, use INTERNAL.            │
│     9.3) Features which contain a constant dupe sequence must be decimated.  │
│              e.g. A silent movie at 1080p24 with a dupe sequence of 1-in-6   │
│              must be decimated to 20 fps.                                    │
│     9.4) For sources which contain footage at varying frames per second      │
│          throughout (hybrid sources), applying an inverse telecine is left   │
│          to the discretion of the group. The NFO must list a reason as per   │
│          the final decision chosen.                                          │
│         9.4.1) It is assumed that the majority of the feature contains       │
│                enough unique frames to not require an inverse telecine       │
│                filter. If it can be proven an inverse telecine or decimating │
│                filter does not result in any loss of unique frames, this is  │
│                considered a technical flaw.                                  │
│                    e.g. The feature is filmed at 29.970 fps, but contains    │
│                    some footage filmed at 23.976 fps. Choosing to encode the │
│                    entire release at 29.970 is valid.                        │
│     9.5) Native and converted frame rates refer to the standard in which the │
│          feature was produced.                                               │
│         9.5.1) NTSC produced content is native to NTSC.                      │
│         9.5.2) PAL produced content is native to PAL.                        │
│         9.5.3) NTSC produced content that is mastered in PAL is considered   │
│                as converted video.                                           │
│         9.5.4) PAL produced content that is mastered in NTSC is considered   │
│                as converted video.                                           │
│     9.6) Sources which contain converted video must be restored to the       │
│          original frame rate.                                                │
│         9.6.1) Converted video includes, but is not limited to: ghosted,     │
│                blended, or duplicate frames.                                 │
│         9.6.2) Converted video does not include NTSC to PAL or PAL to NTSC   │
│                sources which are sped up or slowed down.                     │
│             9.6.2.1) NTSC slow down or PAL speed up must be corrected by     │
│                      muxing video to the correct fps and slowing down or     │
│                      speeding up audio. eac3to is the recommended tool.      │
│                          e.g. Source is PAL sped up, therefore it must be    │
│                          slowed down back to NTSC.                           │

│                artifacts, the CONVERT tag must not be used.                  │
│         9.6.4) In situations where the footage cannot be restored to the     │
│                native format or results in significant issues or artifacts,  │
│                the CONVERT tag must be used.                                 │
│     9.7) True 50 / 59.940 fps video must be released at 50 / 59.940 fps.     │
│          True 25 / 29.970 fps video released at 50 / 59.940 fps is not       │
│          allowed and considered a technical flaw.                            │
│         9.7.1) In cases of varying framerates of 25 / 29.970 fps and true 50 │
│                / 59.940 fps, the framerate of the main feature must be used. │
│                e.g. studio for talk shows, game coverage for sports.         │
│         9.7.2) In rare situations, 25 / 50 fps sources must be restored to   │
│                23.976 or 29.97 fps.                                          │

│     10.1) Sync must not drift during the entire release.                     │
│     10.2) Glitching or unrelated audio that occurs in any audio channel      │
│           present (e.g. L, R, C) is considered a technical flaw.             │
│         10.2.1) Glitching is defined as, but not limited to: an audible      │
│                 glitch, missing audio, pops or clicks as a result of         │
│                 encoding, unintended gaps within playback, missing dialogue, │

│     10.3) An English spoken release must only contain a single English       │
│           dialogue track.                                                    │
│         10.3.1) Except in situations of a remastered/restored source,        │
│                 whereby both original and remastered/restored audio track    │
│                 may be muxed in. It is at the discretion of the group which  │
│                 track is chosen as the primary dialogue track.               │
│     10.4) A non-English spoken release may contain a secondary dialogue      │
│           track.                                                             │
│         10.4.1) The original audio track must be used and forced English     │

│         10.4.2) Secondary dubbed tracks must only be different dialects or   │
│                 varieties of the original language or an English dub.        │
│                     e.g. Original Spanish with secondary Latin Spanish.      │
│                         e.g. Original French with secondary English dub.     │
│         10.4.3) In rare cases, a third dubbed track may be included for      │
│                 another dialect or variety of the original language,         │
│                 accompanied with an English dubbed track.                    │

│     10.5) Non-English spoken releases which use only a dubbed track must be  │
│           tagged as DUBBED.                                                  │
│     10.6) Commentary audio may be included.                                  │
│     10.7) Audio tracks must only be included once at the highest level of    │
│           quality allowed for that resolution. e.g. Including an English     │
│           dialogue track at lossless DTS-HD and lossy AC3 is not allowed.    │
│         10.7.1) This does not apply to embedded cores in lossless tracks,    │
│                 which are broken out by muxers as additional tracks.         │
│     10.8) Including additional special audio tracks (e.g. isolated scores,   │
│           original mixes, different narrators) is allowed.                   │
│     10.9) Supplementary audio tracks must have the title field set to a      │

│     20.5) If multiple releases from a single season require a DIRFIX, a      │
│           single DIRFIX per season is allowed and recommended.               │
│               e.g. Show.Name.S01.1080p.DIRFIX.WEB.H264-GROUP.                │
│         20.5.1) If a single DIRFIX is used, all relevant releases and        │

│     21.1) Same second releases, with a maximum acceptable variance of two    │
│           seconds (+/- 2 seconds) between timestamps reported by a majority  │
│           of pre bots, are not considered dupes and should not be nuked.     │
│         21.1.1) Timestamps must be considered as whole integers and round    │
│                 half towards zero.                                           │
│         21.1.2) The earliest timestamp must be used when considering dupes.  │
│                     e.g. Release A: 1451572201.427158 -> 1451572201          │
│                     Release B: 1451572203.626645 -> 1451572203               │

│                     Release B does not dupe Release A: 1451572203 -          │
│                     1451572201 = 2, i.e. maximum variance allowed.           │
│                     Release C dupes Releases A and B: 1451572204 -           │
│                     1451572201 = 3, i.e. 3 > 2.                              │
│         21.1.3) In situations where a release is found to contain a          │
│                 technical flaw, same second dupes which do not exhibit any   │
│                 technical flaws must be considered the final release. Groups │
│                 may release a DIRFIX to PROPER for their original release,   │
│                 but it is not required.                                      │
│                     e.g. Release A and Release B are released at the same    │

│                     e.g. A 2.39:1 release will not dupe a 1.78:1 retail      │

│             22.2.2.1) Unless it is a transcode of a lossless stream          │
│                       correcting the technical flaw, see rule 1.4.           │
│             22.2.2.2) Unless it can be proven that all untouched sources are │
│                       flawed which cannot be repaired by transcoding, but a  │
│                       WEBRip does not exhibit the same technical flaw(s).    │
│                           e.g. iTunes, Amazon, and Netflix only offer the    │
│                           content. Amazon and iTunes sourced files cannot be │
│                           repaired by transcoding, however a Netflix WEBRip  │
│                           is fine.                                           │
│         22.2.3) Untouched files can proper transcoded releases for any valid │
│                 technical flaw.                                              │
│     22.3) Audio or visual glitches can be propered with a release which does │
│           not exhibit the same flaw.                                         │
│         22.3.1) In situations where mastering issues results in visual or    │
│                 audio glitches, a release must not be nuked until a valid    │
│                 proper, repack, or rerip using a glitch-free source or       │
│                 master is released.                                          │
│     22.4) Highest quality video and audio, and all subtitles present counts  │
│           at time of pre. Propering with higher quality video, audio, or     │
│           subtitles that may appear later on the source is not allowed, use  │
│           INTERNAL.                                                          │
│               e.g. Movie is posted to Netflix with 24 subtitles and 448      │
│               E-AC3 audio, released as is. Two hours later, five additional  │
│               subtitle tracks are added, and audio is upgraded to 640Kbps    │
│               E-AC3 audio and propered. That proper is invalid.              │
│         22.4.1) This does not apply when certain regions may have degraded   │
│                 video or audio quality, but another region on the source     │
│                 does not.                                                    │
│                     e.g. Netflix has limited bitrates to 10Mbps in South     │
│                     America due to bandwidth limitations, but Europe has the │
│                     expected 25Mbps streams. Using the 10Mbps stream from    │
│                     South America is a technical flaw.                       │
│         22.4.2) Propers based on one region having more subtitles than       │
│                 another is not allowed, use INTERNAL.                        │
│                     e.g. Netflix in Japan has four more subtitle tracks at   │
│                     time of pre than Europe, group releases from Europe      │
│                     missing the extra 4 subtitles - propering from Japan is  │

│     23.1) Internals are only allowed when they provide superior quality to   │
│           the last internal/non-internal WEB/WEBRip or non-internal retail   │
│           release, when internaling over:                                    │
│               e.g. Feature is released as WEB, then released again as        │
│               INTERNAL with superior quality. To release another INTERNAL it │
│               must be superior to the last INTERNAL not the first release.   │
│                   e.g. Feature is released as WEB, then retail and then      │
│                   again as INTERNAL retail. To release INTERNAL it must be   │
│                   superior to the non-internal retail, not the internal      │
│                   retail or the first release (WEB).                         │
│         23.1.1) Video quality, a minimum of four B to B frame comparisons    │
│                 (INTERNAL vs last release) in PNG format spread throughout   │
│                 the feature, showing a stark improvement in video quality,   │

│             23.1.1.1) Comparison frame numbers must be included in the NFO   │
│                       file or embedded in comparisons. FFInfo is the         │

│     23.3) Internals with equal files/quality are allowed after one year of   │
│           release and should be used sparingly only when a release has gone  │
│           missing from archives. The release that went missing must be       │

│     25.1) The inclusion of 2-pass in this ruleset should not be misconstrued │
│           as preferring it for every release, CRF must always be considered  │
│           the primary method. Instead, it is encouraged for groups to use    │
│           2-pass methods for rare cases when files provided are of extremely │
│           high quality.                                                      │
│         25.1.1) Video which contains an excessive amount of noise may often  │
│                 result in an unnecessary large bitrate. In such situations,  │
│                 encoding to a smaller bitrate using 2-pass can result in a   │
│                 file size improvement with negligible loss in video quality. │
│     25.2) Dolby Vision (DV) and HDR10+ (HDR10Plus) are considered out of     │
│           scope, due to lack of support and no standard workflow for         │
│           producing them, and must only be released as INTERNAL.             │
│         25.2.1) DV encodes must have DV Profile (--dolby-vision-profile) and │
│                 RPU metadata (--dolby-vision-rpu) set to the same values as  │
│                 the source.                                                  │
│             25.2.1.1) Including the DV enhancement layer on a HDR or         │
│                       HDR10Plus encode is another option.                    │
│             25.2.1.2) Until such a time as Matroska gains support for Dolby  │
│                       Vision, MP4 may be used and dlb_mp4base or MP4Box are  │
│                       the only allowed muxers. It is fully at the group's    │
│                       discretion to work around any pitfalls of the MP4      │
│                       container (e.g. limited audio codec and subtitles      │
│                       support). Groups are exempt from any rules with        │
│                       regards to these pitfalls.                             │
│         25.2.2) HDR10Plus releases, in addition to HDR specifics (see        │
│                 4.23.4), must have SEI tone mapping metadata (--dhdr10-info) │
│                 set to the same values as the source. Tone mapping metadata  │
│                 optimisation (--dhdr10-opt) must be enabled.                 │
│         25.2.3) Any metadata must be extracted from the whole concatenated   │
│                 source, not a partial source. e.g. the first m2ts file.      │
│         25.2.4) Until such a time as mapping metadata to cropped encodes is  │
│                 possible, DV and HDR10Plus are exempt from cropping rules    │
│                 and must be left uncropped.                                  │
│         25.2.5) The rules below will apply in a hypothetical future when all │
│                 pitfalls and issues mentioned above are resolved, support    │
│                 has become widespread, does not result in any playback       │
│                 issues and at least three months have elapsed from support   │
│                 being added.                                                 │
│             25.2.5.1) If the source contains a DV enhancement layer, it must │
│                       be muxed in with the correct DV Profile set for the    │
│                       source during muxing.                                  │
│             25.2.5.2) If the source contains HDR10Plus SEI metadata, 25.2.2  │
│                       is mandatory.                                          │
│             25.2.5.3) 25.2.3 must be respected.                              │
│             25.2.5.4) The HDR10Plus tag must not be used.                    │
│             25.2.5.5) DV single layer encodes (see 25.2.1) or untouched are  │
│                       only allowed when the source is single layer DV (i.e.  │
│                       No HDR, only DV). The DV tag must only be used in the  │
│                       case of single layer DV.                               │
│             25.2.5.6) Dolby Vision (DV) and HDR10+ (HDR10Plus) no longer     │
│                       need be released only as INTERNAL.                     │
│     25.3) YouTube may only be used as a source if geographical restrictions  │
│           apply to legitimate content uploaded by the rights holder or on a  │
│           verified channel.                                                  │
│     25.4) Re-releasing uncropped WEB which has already been released as      │
│           uncropped INTERNAL.WEB or cropped WEBRIP is not allowed and must   │
│           be considered dupe.                                                │
│         25.4.1) Any WEB release nuked solely for not being cropped and not   │
│                 reripped, repacked or propered may be unnuked and now be     │
│                 considered valid.                                            │
│     25.5) Re-releasing any INTERNAL WEB/WEBRips that duped                   │
│           DSR/PDTV/HR.PDTV/AHDTV/HDTV under v1.0 of this ruleset is not      │
│           allowed and must be considered dupe.                               │
