actually this problem was already discussed in this thread: http://forums.adobe.com/thread/1169388
As I didn't want to grave-dig an old thread, I thought I'd make a new one to keep things organized.
Because even after reading through the whole Thread, I'm not really sure what I get in the end.
As stated in this Thread, I get weird colored lines (like a badly printed CMYK picture) when I render to DNxHD 444 with Trillions of Colors (which is 10bit, as I'd assume). Everything's fine when I render in Millions of Colors (8bit) though.
Now when I import the DNxHD 444 file back into AE, it still says it's Trillions of colors which is no surprise as the Codec is always 10bit, if I rendered in 2bit or 32bit.
However, I tested this a bit e.g against ProRes4444 with a simple ramp, and there wasn't really any banding or so (1920x1080 comp, from black to white, at 32bit). Now is there a possibility it still might be 10bit? Or is there no possibilty, whatsover?
What if I imported the AE comp into Premiere and rendered from there, would that be native 10bit then?
I really want to get away from ProRes in my workflow, and DNxHD 444 would be a great alternative.
the comps are of course set to 16 or 32bit. But there's no "Render at max Depth" Setting in After Effects, you get to choose the Bitdepth in categories like "Millions of Colors" or "Trillions of Colors". However, when I set it to Trillions of Colors, it gets the weird lines you see in the other thread
