I'm about to shoot interviews on green screen tomorrow with my HVX200. In the past I've used 1080i and it worked well but am curious if 30p would be better?
The rest of the video clips are all 1080i HDV from the client so my overall sequence in FCP will be a 1080i HDV sequence set to render with prores.
So I will most likely take the green screen video and add the key in it's native format and then export as prores to bring in the HDV sequence.
Progressive usually keys more easily because there are no fields which in an interlaced timeline blurs the edges making the key a bit more difficult. More than i or P, make sure your greenscreen is evenly lit. Use a waveform monitor to be sure, and shoot with a codec that has a 4:2:2 or better color space. Again, there are ways around all of this, but shooting it correctly at the beginning will make your edit life much easier.
