Cineform v Red Raw Comparison Shots?

[Thor Wixom]

Hey Thor,

When do you transcode? Can you transcode from redcine to Cinefrom 444?

Thanks

Sorry, didn't see your post until tonight.

I'm actually experimenting with the Express files. They are 1k, so high enough res to see if things are in focus, but low enough data rate and size to be manageable.

If your computer is fast enough, you could transcode directly to CF444 right off the bat and always be working in online quality... or you could do the Express files first, and then go back and only transcode the files that make it into your final project. The choice is your's depending on what resources you have.

This may sound like a crazy ?, but will CF444 work in TMPGEnc Xpress 4.0?

Yes, all encoding types work, yet most conversion tools will likely request 8-bit and 4:2:2, the decoder will automatically handle the down converison as needed.

[Peter Moretti]

So it sounds like while TMPGENnc Xpress 4.0 can convert CF444 into DNxHD 220x (10 bit 4:2:2), only 8 bits of the DNxHD 220x color info would be useful. The other two bits would be essentially padded with zeros.

Is that correct?

Thanks very much.

[David Newman]

We can provide deep pixel output, but I doubt TMPGEnc would request or deliver it.

[Peter Moretti]

David,

Are you familiar with any way to transcode CF444 to DNxHD 220x and preserve the 10 bit color?

Thanks again.

[David Newman]

Not from experience. You need a application is know support deeper than 8-bit Quicktime and support both CineForm 444 and DNxHD. There are several in the NLE/Compositor class, nothing I can think of that is great for efficient batch conversion.

[Peter Moretti]

Well I have Media Composer 3.0. Is that one of the NLE's you're thinking of? Even if batch conversion isn't an option, could it work on a one at a time basis?

[David Newman]

Not sure, you will need to check if Media Composer support 'b64a', 16-bit per channel RGB via QuickTime.
