Hello, recently switched from a Mac to a PC and without the use of ProRes now I'm trying to find a suitable replacement for rendering high-quality footage. Can someone recommend a codec that fits the specs in the title please? It seems AVI & Animation only support 8bpc, and I'm just plain unfamiliar with anything else really. Any resources regarding this topic are also welcome, wouldn't mind doing a little research.

Thanks so much!

Get your mitts on QT Pro for Win -- version 7.x. You'll have access to PNG & JPEG 2000.

There aren't any codecs with 16-bit color. Not even ProRes 4444.

Really? So what's the output option in AE for "Trillions Of Colors"? I always assumed that was 16-bit?

And yes I am currently using the QuickTime PNG codec so I guess I'll stick with that

I'm not sure if the Trillions of colors deal shows up in PNG. It's good in image sequences.

Like ProRes 422, PNG is a 10-bit codec. And it's lossless to boot.

Awesome, thanks. But just out of curiosity- in general what does the "trillions of colors" option represent?

I wish I could say. I've always wanted to use it myself. None of the codecs I use for delivery are capable of it.

[Ryan Paterson] "But just out of curiosity- in general what does the "trillions of colors" option represent?"

"Trillions of colors" in this context means that the output module will pass a 16bpc RGBA image to the encoder. To output 10-bit ProRes or CineForm, for example, you'd need to render with Trillions of colors. Rendering with "millions of colors" would only provide 8-bit renders from the output module to the encoder.

Creative Cloud includes support for CineForm, a cross-platform, high-quality mezzanine format comparable in quality and compression ratios to ProRes. CineForm supports 10-bit YUV and 12-bit RGBA.
