It depends on how it's going to be used (e.g. max compression for storage, vs. maybe quick decoding for editing intermediate etc....), what criteria are important to your situation
Factors influencing what you might choose include : compression ratio encoding speed decoding speed compatibility with various host applications (not all "lossless" codecs are treated as lossless in some programs) platform support mac/linux/win open source vs. payware pixel type , bit depth, colorspace support md5 / error checking for archival |

I use x264 for lossless encodes with mp4 as extension, because the mkv produced by x264 has no index -> slow seeking.
For lossy encodes also x264 and x265 + mkv. Script editor notepad++ and virtualdubmod.

Anyway, to respond to the OP, it entirely depends on your source material. Not all color spaces are supported by all codecs, so in some cases that alone can make the decision for you. Also, some codecs (e.g. lossless x264) actually do interframe compression, so noiseless sources can really shine on them, whereas others are pure intra encoders which can be as good as or better than x264 for noisier sources. |

Technically, all "lossless" codecs will all have the same "quality" But beware not all programs treat them as "lossless" . So the situation specifics and how it's going to be used are important considerations. For example if you had a YUV source and used huffyuv, or ffv1, or lagarith, or ut video codec - they wouldn't be lossless in the majority of windows NLE's; most treat them as RGB. But open source programs like ffmpeg typically handle the correctly A long GOP lossless codec , such as x264 in lossless mode or ffv1 in long gop mode will typically offer the highest compression ratio . But many programs like video editors will not be able to read either of them (lower compatibility) Newer versions of Adobe PP , is the one NLE that treats lossless x264 in 8bit, 10bit, and 4:2:0, 4:2:2, 4:4:4 as true lossless for import and export. There is an open source plugin "voukoder" that can export directly using libx264 as well . It also has ffv1, libx265, but they aren't treated as lossless on import (export is ok) |
