4:4:4 cineform copy
If I take a 4:4:4 source and render it out to the cineform intermediate codec V2.5. Will the original source maintain the 4:4:4 colour sampling or is it sampled into 4:2:2 in the cinform codec? Thanks in advance for an answer.

It is resampled to 4:2:2. We have a 4:4:4 codec coming for higher-end work, but today's CineForm Intermediate files are always 4:2:2.

I recently read in one of your whitepapers (I hope I'm not misreading it) but it said that you're also in the future going to support uncompressed video with reater compression. Is that true and if so how do you do that?

We have a lot of things in the works but I have never heard of "reater" compression and we certainly have no interest in uncompressed (as the is what we are solving.) ;)

Greater compression implies more compression, if anything as computers and disks get faster we might offer slightly less compression for the high-est end productions -- although our bit-rate to quality ratio is pretty damn good today.
