Interesting... Thanks for that info!
Lagarith is out of the game anyway, due to its windows-focus and lack of
additional advantages over Huffyuv or FFV1.

What is the implementation status of x264 lossless in libavcodec, and
would it be possible to have intra-frame encoding only? I've read that
it's compression is inter-frame.
@Lars:
Currently, it's preferred to have keyframe-only codecs for video
archives. It makes a lot of things easier and less troubles in case of
data problems.


However, the archive I'm working on will deal with lots of old analog
material, so if FFV1 is better at dealing with noisy sources, that
sounds good. :)


Apart from that, do you generally think it's a good idea to consider
FFV1 as preferred codec for a video archive instead of Huffyuv?

Thanks,
Peter
