RED Proxies to Color and back to FCP
on Sep 14, 2009 at 9:01:39 am

Hi,

I've been reading around a lot but still cant find a straight answer to my question regarding RED Proxies and Color. I hope i'll find it here:}

I need to know what happens when sending M porxies from FCP7 to Color 1.5.

Does Color work with the actual RAW files? What would be the difference, when going back to FCP, if I used one of the transcoding methods described in the RED FCS Whitepaper instead?

This is concerning a commercial clip for broadcast.

I'd really appreciate you help on this.

Many Thanx
Boris

Yes you grade off of the R3D originals and then you would typically send back ProRes renders to FCP.

Thanx, Noah, for your reply!

If i understand correctly, it makes no difference whether proxies or transcoded ProRes files are used for editing as far as Color and the resulting ProRes output back to FCP is concerned.

Am I right to assume that?

Thanx again for your help!

Boris

Actually it matters a lot. Proxies and transcode to Native will grade to R3D files. Transcoded ProRes will grade the Transcoded ProRes files. The FCS Whitepaper included with RED's FCS installer gives a pretty good explanation of what happens when:

as does my book's FCP chapter:

Main difference: you'll loose some dynamic range for correction if transcoding to anything else but ProRes 4444 and you don't have access to the RED settings in Color. I haven't tested ProRes 4444 enough yet to be sure it's no disadvantage against RED originals.

Hope this helps,

Prores 4444 is fine for fidelity but having access to the RED metadata tab in Color is really the key thing and you can get that with any of the transcodes or native. Just is a question of whether you have to go through Clipfinder or Cinema Tools to tell Color to go back and look at the R3D files.

Thank you both for your answers!

I have read the Whitepaper and everything else on the matter I've come across online. This here is the answer I was looking for, thanx Noah! It now makes me wonder why transcode to Native instead of just using proxies provided?

Once again, thanx, your help is much appreciated!

Boris

Transcode to native is more reliable.

The proxy workflow is not recommended by Apple and we have experienced some flaws with it, unfortunately not only the one Colorfixer can cure.

Hope this helps,

Transcodes have much better playback and real-time performance than proxies and less media management issues. If you give up a bit of time upfront you gain a lot of workflow efficiency by transcoding.
