[sofia tyler] "Is this also the case for, APPLE PRO RES 422 and other FULL HD CODECs"

You mean like DVCPro HD? Nope, it's fine. ProRes 422 is okay, too. The rule of thumb is "stay away from HDV footage that's still in its native capture codec".

If you do a lot of chroma key work, consider this: HDV is to real-live HD what DV is to Digibeta (or any other professional SD format). In fact, the quality hit going from HD to HDV is a lot bigger. If you think DV's heavily compressed, HDV's a LOT worse!

I'd use HDV for chroma key work, but I'd use it ONLY in SD projects -- you can hide a lot of color resolution sins by reducing the scale. But HDV chroma key work in a an HD project? Certainly not for a project I expected to get paid for.
