Can 10Bit LOG DPX/Cin files from Red be Color Corrected in FCSP2?

[Graeme Nattress]

No, softening is the artifact of wavelet compression when it is compressed far enough till you start seeing artifacts, so in that respect you're totally right. Indeed, wavelet transforms are sometimes used as a "step" in noise reduction algorithms. However, I just didn't want people to think that wavelets cause image softenening by themselves.

REDCODE is not lossless. It's very good looking, but it's not lossless. You can't get lossless codecs that run much better than 2.5:1.

Wavelets do not make the image soft. If you over-compress wavelets, you can get some softening as an artifact. Be careful you don't imply wavelets do "things" to the image. Wavelet compression can also be totally lossless, but the files are too big and slow for that to be of use for us.

Thanks you. So We can say it's possible to record with REDCODE an 24 MB/sec and Proxi at 1K on the same Sata disck (RED STORAGE). Make offline with proxies then conform offline with the 24MB 4K REDCODE Raw, and have "quasi-invisible compression". So conform and 4K manipulation (color grading and compositing witch is done in 98% of any feature film) as long as software support REDCODE codec. Codec that don't need to be render with hundred of CPU, than output in 2K DPX and print feature at your favorite lab. And that it?

When red gonna be avaible if purchase to day?

REDCODE RAW is it's own proxy - we just tell the file to decode at the lower rez - same file though. That means you don't have to do a full decode at 4k until you need it.

As for delivery - that's a Jim question he's answered elsewhere....

You would likely run shots through Redcine to do a high-quality/slow de-bayer, do some image processing (e.g. CC matrix, white balance, highlight recovery; sort of like a one-light), and then output files that are compatible with your system (DPX, TIFF, etc.).

Not sure to clearly understand Glenn. Codec Redcode is supported by FCP and scratch as far as I'm right. So can run the 24 MB 4K into scratch and directly grade in 4K. Or we have to render the codec in DPX log 10bit or TIFF 16bit linear before get into grading

By the way thanks all of you for your answer. I try to build a DI post-house in Montreal. We have now access to Sony HD SR HD cam DVC Pro HD and so on. I really want to bypass film laboratory who want to preserve their investissement in 35mm laboratory and Scanner + DaVinci.

For systems other than Scratch you will likely need to go through Redcine to convert your Red footage into DPX or TIFF (whichever works with your grading system).

2- I'm not sure here, but for Scratch you may also wish to go through Redcine for high-quality de-Bayer. I assume (perhaps incorrectly) that if Scratch were to de-bayer at high quality, that would really slow down real-time performance making it unsuitable for grading. Unless you de-Bayer all your footage beforehand first, and then conform that into Scratch.

Lucas Wilson is from scratch and posts on these forums. He could likely give you a better answer.
