Transcodes
Transcoding (verb) a file means converting from one format to another. A transcode (noun) can mean any converted file, but is usually used in a negative context (as in a bad transcode).
Good Transcodes
A good transcode means that during the transcode process, the file has either never been converted to lossy, or the file has only been converted to lossy once during the last step.
Examples of good transcodes:
- uncompressed lossless > compressed lossless
- compressed lossless > uncompressed lossless
- compressed lossless > compressed lossless
- uncompressed lossless > lossy
- compressed lossless > lossy
Bad Transcodes
A bad transcode means that during the transcode process, the file has either been converted to a lossy format more than once, or the file has been converted from lossy to lossless.
Examples of bad transcodes:
- higher lossy bitrate > lower lossy bitrate
- same bitrate lossy > same bitrate lossy
- lossy > lossless
