Tough choice.
I'm gonna go for x265 --lossless just because it's generally more supported by NLE etc than the alternatives like HuffYUV, Lagarith and UTVideo and it performs well... |

h265 is slow. Also- is playback really that good for anything above 4:2:0 10bit? For archiving you want at least 4:2:2.
FFV1 is used by many institutions as archiving format. Last edited by kolak; 11th July 2021 at 12:31. |

For me...
Saving to x264 lossless in mkv has always produced reliable results when generating encodes with VirtualDub2.

What kind of movies are we talking about? If new HDR then you can use 10bit HDR. Which codec? That's the problem. Cineform is out. MJPEG2000 is out. The JPEG XS was not seen by anyone. X265 at high bitrate is best in 4K.
Old movies only in RGB. Don't record on Bluray. Will the AV1, VVC, EVC codecs satisfy the recipient in 20 years? No, then it will be 16K, and we will be able to throw 2K films in the trash. |

My 2041 vision has HDR 4K with dynamic metadata as the default, probably in H.268. |

UTVideo and MagicYUV are good, i'm using them all the time but for intermediate production files. They are fast, but for archiving, there is probably slower codecs with better compression, like x264 or x265 lossless.

x265 lossless can be sped up a lot by doing IDR-only (--keyint 1) and using a faster --preset. You can really crank up -F in that case, as each frame is encoded independently. And better yet, you'll get HW decode on modern GPUs, which can give you performance back.

How much are you going to gain on typical film source (with all grain/noise etc.) using h265 lossless compared to other "fast" codecs?
I never found real world lossless scenario which would give more than 2-2.5x compression (regardless fo the codec). How difficult would be to do hybrid mode which hits chosen ratio (eg. 3:1), but when it can switches to lossless mode? HDCAM-SR worked this way no? Last edited by kolak; 12th July 2021 at 19:15. |

And yes, about 2.5:1 for content with grain or other random noise is about what you can expect. Totally clean content in Long GOP can go way, way lower. That's less than you'll get with ProRes and other intermediate codecs. Actual mathematically lossless is rarely needed, and should only be used when it really is. Like delivering VFX with alpha for compositing. |

My favorite lossless codec is MagicYUV. Very fast.
