Red response to their customers need for 4k editing, color correcting, grading, etc

Hi Lucas,

Great to see again too.

I understand you are saying but from what I know, CineForm is not a "Quicktime" compatible codec at all. While REDCINE maybe GPU optimized, CineForm is not; rather it is highly CPU optimized. From what I know it is so highly specific that porting to another processor is all but impossible.

I could be all wrong, but we don't really have to guess. This theory can easily be tested, CineForm has try out programs that can be downloaded. Is this something that you can test Lucas? I would be very interested in learning the outcome.

Actually, Cineform added Quicktime and Intel Mac support so Lucas is correct to say "should" work.

So, lets test this theory. I would love to be wrong about this one!

RedCine is GPU based, correct? If so, that would mean everyone will need a compatible card. Recommendations for good performance? Are we talking nVidia or AJA/Blackmagic?

I do remember Rob Lohman stating that RedCine could take advantage of normal consumer Nvidia cards, which is good since I have a nice GeForce 8800GTX with 768MB of GDDR3 RAM sitting in my quad core box. Makes sense anyway since the far costlier Quadro series are actually identical hardware with different firmware ID and a different set of drivers optimised for slightly different tasks. Seems a waste of money to go the Quadro route in any modern software that doesn't require the videocard to output in HD-SDI or some other specialised form.

This is my understanding as well, and as far as I understand this is not an issue. One should be able to create Cineform AVI files (using HDLink) from the output formats of Redcine including Quicktime files.

Instead, the real issue is, will it be possible to convert Red 4K raw files to Cineform 4K raw files? If so, that would be remarkable and yield an amazing and highly cost effective workflow.

Kevin,

We been a QuickTime codec on the PC for nearly two years and a shipping QuickTime codec on the Intel Mac for about 4 months. We looking forward to any testing, unfortunately we don't have Redcine betas to do the testing ourselves.

All,

Generally we expect QuickTime exports to work fine. However, we will want to confirm that pixel formats are a match between RedCine the the CineForm codecs. The common deep 'b64a' format (16-bit per channel) is supported, yet on the PC the byte ordering is ambiguous, AE7 and Combustion use one byte order and AE CS3 uses the other. So we may need to tweak things for Redcine. Any information on the supported pixel formats in advance would be helpful. For of those lucky enough to have "access" we can prove 4K licences for testing purposes.

Hi David,

Thanks for the correction. I guess I was working with out of date information about CineForm. Please PM me and we can discuss further testing. By the way, I do fully agree, the byte order problem is prevalent for many multi-platform applications.

Except that the 8800 series have Overlay disabled in hardware. This has proved to be a problem with using Cineform on the PC.

You can use the 7950 instead if you want to stick with consumer based cards. I use the Quadro FX4000 myself.

Why not this one:

4K Raw -> Cineform 4K or 2K files -> Premiere Pro -> cut & use filters & transitions -> hit render, if needed and/or export to what ever format you like[...]

Fine for some projects if you are happy to be limited to the Premiere/Avid in app grading tools.

Can someone fill me in on the details of what that means. I have a 8800GTX coming in the mail. Is video overlay no longer an option, and is it still available on the new QuadroFX4600? That would be a big disappointment.
I can understand why Nvidia would do that, from a business perspective, but it would be a real bummer.
