Additionally:
here is also a good understanding description of the LOG vs LINEAR issue:

It is indeed possible to decode back to DPX- I've losslessly

But it's some context loss. For instance if the source DPX is logarithmic I'd
be skeptical that the ffv1.mkv rendition would present logarithmically.
I haven't tried it myself, but actually logarithmic should be stored in
FFV1 as-is.
The context how to interpret the color information is currently not
automatically stored, and would therefore have to be provided manually
when re-transcoding, or when playing back.
Has anyone tested this yet?
Kind regards,
