===============================
EFFECTIVE DATE: October 1, 2011
This rule set has been approved by the following music video groups:
CMS FRAY GWViD iUF JESTERS MV mV4U mVa NaWaK PmV SNO SRP uva UVZ VFi
###### DEFINITIONS / TERMS ###################################################
- "HD" refers to the resolution requirements outlined in 7.1
- "DDC" refers to Downloadable/Direct Digital Content which is not freely available
- "source" refers to the actual source material (i.e. dvd, dvb stream, etc.)
- "replacement" refers to material used to REPLACE something from the source
- "untouched" refers to content which is unaltered in any way
- "IVTC" is an abbreviation for Inverse Telecine
- "EXTENDED" refers to videos containing additional intro/outro/intermediate footage.
- "Live performance" refers to any performance that is not part of a music video.
- "Concerts" are simply live performances regardless if it's at a stadium, festival,
concert hall, club, etc.
- "Bootlegs" are defined as any self-made or live-filmed content not produced by the artist
or their respective label and are not intended or licensed for network broadcast, commercial
sales, or public release.
- "Native" refers to the standard in which the video was produced, e.g. NTSC or PAL.
NTSC produced video is native to NTSC, PAL produced video is native to PAL.
Videos may be either IVTC'able or progressive.
PAL produced video that is broadcast in NTSC is converted.
NTSC produced video that is broadcast in PAL is converted.
In some special cases converts can be restored to their original progressive state.
- "Mod8" refers to a multiple of 8.
- "cropped DAR" refers to the display aspect ratio after removing the letterboxes.
- Any release pre'd in the MVID section must conform to this ruleset.
###### CONTAINERS ###########################################################
1.1) Allowed containers are: MKV
1.2) MKV container:
1.2.1) mkvmerge MUST BE USED to mux.
1.2.2) Soft subbed lyrics are optional.
1.2.3) Hard subbed lyrics are not allowed.
1.2.4) Setting chapters in mkvmerge is allowed, but not required.
1.2.5) Header compression must be disabled in mkvmerge by adding the following to
the BEGINNING of the command line: --compression -1:none
###### AUDIO #################################################################
2.1) Allowed audio formats are: MP2, MP3, AAC, AC3, and lossy DTS. DTS is allowed from retail sources only.
2.2) All audio must have a minimum sample rate of 44.1kHz.
2.3) The first/default audio track MUST BE FULLY SYNCED.
2.4) When no lip-sync is present in the video, you must use audio which matches the source.
If you're unsure about this, put an alternative version as a 2nd track.
2.5) Replacement audio, if exists:
2.5.1) The best quality replacement audio for the song must be used. If multiple retail audio
sources exist, any may be used but whichever has the highest average bitrate is recommended.
2.5.2) The best quality replacement audio for any sfx must be used.
2.5.3) In the event mixing song and sfx sources causes an obvious difference in quality, or the
speed (or pitch) difference is too great, the original source audio must be used.
2.5.4) Audio used for bootlegs, mixtapes, promos, etc. is often NOT the final mastered
retail audio. Releases using these sources can be propered if/when final retail
audio becomes available UNLESS it is near-same quality.
2.6) When using scene or self-encoded audio:
2.6.1) 2 channel audio must be MP3. 3 or more channel audio must be AC3.
2.6.2) MP3 scene audio must not be nuked for a technical reason relating to the source (or encoded)
audio being used at the time the music video is pre'd.
2.6.3) Ripper-encoded MP3s must be in compliance with the most current MP3 scene ruleset settings.
2.6.4) AC3 must be encoded at 128kbit per channel, with a maximum of 640kbit.
2.6.5) Advanced AC3 encoder settings such as gain changes, filters, etc. are not allowed.
2.7) Audio from a vinyl source is not allowed under any circumstances.
2.8) If part of the source audio is only available from the source itself, it must be inserted
into the replacement audio. This includes all sound effects.
2.9) Transcoding unedited/untouched audio from one codec to another (unless to comply with 2.1), or
re-encoding at a higher bitrate will NOT increase quality in ANY way, therefore not allowed.
2.10) If no editing is required, the replacement audio must be directly inserted as-is.
2.11) Multiple audio streams are allowed at the rippers discretion. For example,
including both censored and uncensored audio, or multichannel AC3 audio.
2.12) Altering the audio in any unnecessary way is not allowed. If gain adjustment is needed to even the
volume between sfx and music, the sfx gain should be adjusted and music gain left alone. Do NOT normalize
audio under any circumstances!
2.13) Variable Bitrate WEB audio sources must have a minimum average bitrate of 160kbit. Constant Bitrate
WEB audio sources must have a minimum bitrate of 192kbit.
###### VIDEO #################################################################
3.1) Allowed codecs: x264
3.2) Video source MUST BE digital and NOT be passed thru any analog
equipment (svideo output, analog capture card, etc.).
3.3) Releasing raw source is NOT allowed!
3.4) FPS must match that of the source, unless any of the following exceptions are met AND the
replacement audio is in sync with the altered FPS:
3.4.1) IVTC is applied.
3.4.2) 50+ FPS sources where every other frame is a dupe, in which case half-framerate is allowed.
3.4.3) Videos that don't need or contain any deinterlacing may be reversed/decimated back to their
original FPS and considered native if the source was sped up/down, or contains dupe frames
in the following orders: 5,6,25
3.4.4) Converts where a restore/deinterlace method can be used to reverse back to the original FPS.
3.5) Dupe frames must be removed unless needed to maintain sync.
3.6) Encodes must be within 5% of the original aspect ratio. To calculate
the AR % error use: (Release - Original AR)/Original AR x 100
3.7) Upscaling is not allowed.
3.8) Telecined video must be MANUALLY IVTC'ed using:
2:2 pulldown NTSC/PAL
3:2 pulldown NTSC
3.8.1) If IVTC is not possible, the reason must be stated in your nfo.
3.9) For non-telecined interlaced video, a deinterlacer must be applied before
encoding.
* It's STRONGLY RECOMMENDED you DO NOT use the following deinterlacers/filters
due to poor quality output: fielddeinterlace, dgbob, decomb/telecide, VerticalReduceBy2
3.10) Interlace of ANY KIND is not allowed. If you can see it, it's not allowed. No exceptions.
3.11) Vfapi creates unnecessary colorspace conversions resulting in degraded color quality
and is not recommended.
To avoid this if using TMPGEnc for manual IVTC, use "tprivtc" to import your
.tpr project file into avisynth.
3.12) Videos containing mixed-fps/vfr (variable frame rate) must be IVTC'ed to preserve the vfr
if IVTCing them normally causes jumpy/choppy playback.
3.13) Deinterlacing the entire video is not permitted on IVTC'able or progressive sources.
3.14) Extended videos are considered different versions from that of non-extended versions and therefore
can not be used to proper non-extended versions. Refer to rule 8.1 for how to name extended versions.
3.15) Adding an intro/outro, or watermark is not allowed.
3.16) Freely available content, such as videos downloaded from YouTube, or subscriber based services
that don't require payment, must be pre'd as internal.
3.17) 25->24/23.97 (PAL->NTSC FILM). If sped up video requires an audio edit, such as input with sfx or
an audio cut, source audio must be used at 25fps. If no edit is needed, use replacement audio at 23.97/24.
3.18) Converting 2D <-> 3D is not allowed.
3.19) If DVD5 and DVD9 sources are both available, DVD9 must be used.
###### CROPPING ##############################################################
4.1) Cropping the picture must be avoided if possible.
* Stretched/duplicate lines caused by the provider are not considered part of the
video and must be cropped out!
4.2) Black letterboxing/borders (partial or full) must be removed.
4.3) Both horizontal and vertical resolution must be cropped so the resulting resolutions are mod8.
4.4) Cropping is allowed using the MKV container. When doing this, define the correct AR
when muxing with mkvmerge. The encoded source must be uncropped, and the mod8 requirement in
4.3 is also unnecessary.
* This feature works correctly using newer mpc/mpc-hc, haali splitter & coreavc. However, while
other player/spitter/codec combinations may work as well, some still haven't added support yet
or their support isn't 100% (such as with VLC). While allowed, mkv cropping isn't recommended
until it works correctly in more player/codec combinations.
###### x264 ##################################################################
5.1) Encoding must be done using within 50 revisions up to the most current x264.exe from http://x264.nl
at the time of pre.
5.2) Codecs supporting VFW are NOT permitted!
5.3) Rips must use one of the following: main profile (level 3.0) for non-HD
high profile (level 4.1) for HD
5.4) CABAC encoding must be used.
5.5) In-loop filtering must be used.
5.6) Average quantizer must be lower than 28 for SD, and 30 for HD. Recommended is 24 or less.
* You can use the "average drf:" field in avinaptic to check this, or use the following
formula:
AVERAGE=(I-Frame avg*I-Frames+B-Frames avg*B-Frames+P-Frame avg*P-Frames)/total frames
* "--aq-mode" has nothing to do with this. 2 pass, crf, and abr videos can have their
average quantization value calculated.
5.6.1) If a higher quantizer is needed then the reason must be stated in the nfo.
5.6.2) qp is not allowed.
5.7) When using a non-square pixel shape, you MUST encode using the "--sar x:y" option and
mux with "--engage keep_bitstream_ar_info". SAR can be calculated using the following
formula in the following examples:
SAR = (cropped DAR X * cropped height):(cropped DAR Y * cropped width)
ex. 1: SAR = (16 * 576):(9 * 480)
SAR = 9216 : 4320
SAR = 32:15
ex. 2: cropped DAR X * cropped height 16 * 576 9216
SAR = ------------------------------ -------- = ---- SAR = 32:15
cropped DAR Y * cropped width 9 * 480 4320
5.8) REQUIRED encoder settings:
5.8.1) --aq-mode must be enabled
5.8.2) --bframes 3 (if vertical res is greater than 864), otherwise --bframes 16
5.8.3) --subme 9 (or higher)
5.8.4) --ref 4 (if vertical res is greater than 864), otherwise --ref 5
5.8.5) --me umh (or higher)
5.8.6) --trellis 1 (or higher)
5.8.7) --merange 32 (if vertical res is greater than 864), otherwise --merange 24
###### SD (Standard Definition) ##############################################
6.1) Maximum allowed average bitrate is 6000 kbps.
6.2) Maximum allowed resolution is 720x576.
###### HD (High Definition) ##################################################
7.1) Source resolution must have a minimum of 1280 horizontal pixels or 720 vertical pixels.
7.2) For converts, same rules apply as for Standard Definition.
7.3) Upscaled sources are NOT true High Definition and are not allowed for
HD releases. These must be ripped according to Standard Definition.
7.4) Maximum allowed average bitrates are as follows:
7.4.1) 720p is 10000 kbps.
7.4.2) 1080p is 14000 kbps.
7.5) 1080i sources which aren't IVTC'able must be scaled to 720p.
###### DIRECTORY/FILE NAMING, TAGGING, PACKAGING #############################
8.1) The directory naming scheme is REQUIRED and enforced to maintain consistency
in the scene. The following is a list of all valid tags, where applicable.

outlets. You are paying for a service, not purchasing content.
8.1.4) Rips containing a non-english majority of vocals must be tagged with the corresponding
ISO 639-1 language code: http://en.wikipedia.org/wiki/List_of_ISO_639-1_codes

in rule 1.1, and video codecs in rule 3.1.
8.2) SFV and NFO are required.
8.3) Live performances, including pre-recorded, must include the show name (if applicable)
and original broadcast date. If the performance wasn't broadcast (such as concerts
released straight-to-video), use the date of the performance. Live performances used as music
videos do not need a date.
8.4) Events & awards shows occurring annually or less frequent (such as the Grammys and Rock am Ring),
or occur more than once a year and are named with an edition/series number (such as The Dome),
must be tagged with the show name and year OR the edition/series number.
8.5) The appropriate tags, outlined in 8.1, must be used when applicable.
8.6) RARing is at the rippers discretion but recommended for releases >=500MB. RAR'ed releases
must be packaged as follows: 15MB, 50MB, 100MB or 200MB rars, and a 1 minute sample.
8.6.1) RARing single file releases <500MB is not allowed.
###### CONCERTS, LIVE PERFORMANCES, FREESTYLES, ETC. #########################
9.1) Multi-pass vbr or crf encoding must be used for these. You may also split into
separate tracks (NOT separate releases).
9.2) Two or more songs by the same artist, from the same performance/event, ripped to
individual files must be packaged in ONE release, similar to an MP3 album, for example:
DIRNAME/00-artist-concert_title.nfo
DIRNAME/00-artist-concert_title.sfv
DIRNAME/01-artist-introduction.mkv
DIRNAME/02-artist-song1.mkv
DIRNAME/03-artist-song2.mkv
...
* refer to 8.1.1 for DIRNAME examples
9.2.1) Award shows are an exception and must be packaged as single-song releases
with any intermediate footage (interviews, presentations, etc.) removed.
9.3) Third party videos (commercials, karaoke, bootlegs, etc.) are not allowed.
###### NFO FILE ##############################################################
10.1) NFO's MUST contain:
- artist name and song title
- format (x264)
- resolution and aspect ratio
- video source (DVD, DVB, DVB 1080i, DVB 720p, scene release title, etc.)
- audio source (RETAIL CD, RETAIL WEB, scene release title, etc.)
- deinterlace filter name(s) and IVTC method used
- genre
- year of video release
- repack reason (if applicable)
- proper reason and name of release you're propering (if applicable)
* Broadcasted live performances MUST include the show it aired on and original air date.
Other recommended (but not required) information to include:
- filesize
- video playtime (min:sec)
- audio/video bitrate
- album name (if available)
10.2) If a scene-released audio or video source was used, the exact release name must be included.
10.2.1) While we DO NOT require groups to ask "permission" to use sources, we encourage it.
10.3) If non-scene web audio was used, the source/store url must be included.
###### DUPES #################################################################
11.1) mkv/x264 dupe all releases prior to the date of this ruleset.
11.2) Fullscreen dupes widescreen. Widescreen does NOT dupe fullscreen.
11.3) 720p/1080p do not dupe each other.
11.4) The non-DDC dupe priority list is as follows, from highest to lowest:
NATIVE BluRay/DVD RETAIL rip
NATIVE BluRay/DVD rip
NATIVE HDTV rip
NATIVE SDTV rip
CONVERT BluRay/DVD rip
CONVERT HDTV rip
CONVERT SDTV rip
11.4.1) Native HDTV rips are NOT duped by DVD rips.
11.5) The DDC dupe priority list is as follows, from highest to lowest:
NATIVE HD DDC RETAIL
NATIVE HD DDC/SD DDC RETAIL
NATIVE SD DDC
CONVERT HD DDC RETAIL
CONVERT HD DDC/SD DDC RETAIL
CONVERT SD DDC
* NOTE: We want to allow users the choice of both fullscreen/widescreen rips, not force one or
the other simply because it was released first. That is why native HDTV rips are
allowed after SD dvdrips, as long as a native BluRay doesn't exist.
11.6) We do not acknowledge releases pred in other sections therefore no release in MVID is subject
to dupe of a non-MVID release.
###### PROPERS/NUKES #########################################################
Some example PROPER/NUKE reasons are as follows:
12.1) out-of-sync audio
12.2) incomplete or missing audio/video
* NOTE widescreen can not be propered by fullscreen with this reason!
12.3) improper or no IVTC when applicable
12.4) 1 or more frames containing interlace

* NOTE TO NUKERS/RIPPERS:
If you don't know how to determine things like progressive ghosting vs. a bad ivtc, or a
bad ivtc in general, please ask! We'll be more than happy to explain anything regarding
our rules to eliminate any confusion!
Use common sense. For example, we list all valid tags in rule 8.1. Any tag not listed
in rule 8.1 is obviously invalid and therefore not allowed, and therefore nukable.
Some groups take advantage of mkvcrop so make sure you're using a compatible player before
nuking for "bad.crop"!
