I'm gonna get some footage from a feature shot in HDCAM 25p (Sony F900), and will have to key out some green screens and switch their background to high-res still images on After Effects.
The feature is going to the lab to get blown-up to 35mm, and I've been told that the edges of the keyed out green screen will be more grainy, on the 35mm - or something like that.
Is this a known problem when doing chroma-key on HDCAM later to be blown-up ? Do I need to take some special actions or handle the keying different than usual?
Another issue- how can I prevent the footage from flickering when blown-up to 35mm?
Oh- the final master tape sent to blow-up, will be HDCAM 25p as well.
