DPX 10-bit Log vs. AJA Kona 10-bit Log RGB Codec

[Wolf Austad]

All RGB is rendered to 8-bit in FCP. One can apparently assemble in FCS2 Color with a float renderer, BUT as far as I know, there is still a bug in Final Cut Studio 2 and/or AJA Kona 3 drivers preventing the use of 4:4:4. That was the case last time I had a project needing this workflow. I have not seen nor heard of AJA posting a fix.

To work in 4:4:4 you have to revert back to FCP 5.1, but then you are stuck with 8-bit rendering which I think is clearly unacceptable for a film out…

Oh, and I am not really a post guy. Just a DP who care about my images… I know this because I had a few projects that we tried to put through this pipeline, and it didn’t work.

P.S. IF there is a fix from AJA, I would love to know about it!

Some of the most knowledgeable post people that I’ve met have just been DPs “who care about their images.”

I’m in contact with AJA support discussing this right now. I’ll keep you updated with what I learn.

You can render out to the same codec, but I don’t believe FCP does 10 bit renders. Also, it won’t be in Log space. AJA is not the one to answer this question as it’s FCP that is doing the render.

I wouldn’t be too hopeful of FCP being able to handle this level of work for a long time, if ever. That is why I mentioned Scratch. Probably the cheapest way to get the quality you want.

Now if you are happy in a linear space, with 8 bit rendering, knock yourself out. Otherwise just treat FCP as the offline tool.

Wolf,

AJA support really helped me to figure out what I needed to know. I’m not sure about the answer to your questions, but I’m sure AJA would be totally up for discussing it with you.

Good Luck!
