Thanks kolak.

I have had a look at other high-quality 10-bit all-intra codecs and there we have:

huffyuv, FV1
not compatible with Edius

cineform
compatible but very bad timeline performance

ProRes
compatible, relatively good timeline performance, very fast encoding, 422HQ has IQ pretty close to HQX at highest quality setting (to split hair: HQX superfine has a close to invisible advantage in preserving detail)

DNxHD
compatible but not available

Any other suggestions ?
HEVC / H.264 are not all intra so probably not the best intermediate choice...

My questions:
ProRes could be an candidate. I wonder why this proprietary codec is available in vfw from a technical pov (I thought vfw could not manage >8 bit ?) and from a license pov ? I mean 422HQ is pretty good and XQ freely available - how come ?
Are there any other hq-codecs available and installable - how does that work ?

Thanks for some elucidation
