where can I find green screen pro res files to test my chromakeying with???

[Nicholas Natteau]

Does anyone know where I can find Apple Pro Res green screen files I can test my chroma keying skills with.

I tried "Hollywood Camera Work" but they only have PNG files. Was hoping there was a web site out there with links to downloadable unkeyed footage.

So far I haven't been having much luck with my chromakeying. And I'd like to test my skills with properly lit green screen footage.

Thanks in advance.

Why does it need to be ProRes? (PNG actually offers higher quality, you know. PNG is lossless, ProRes is not.)
