Green Screen questions
I have a shoot next week where we need to shoot a talking head green screen and also some documentary footage of a race.
We're shooting HVX to P2 cards. I had advised the client to shoot 720 24PN or 30PN for all of it , but now I'm seeing posts that seems to suggest shooting the Green screen at 1080, which I have actually never done. Shooting the doc material @ 1080 sounds like it will be very intensive on the P2 cards though. 1. My ideqa now is to shoot the doc stuff ( of a bike race) at 720/30PN or 24PN and then shoot the green screen at or 1080 60i/30P or 24P (? I could also shoot it all at 1080 60i .) Finally then downrez the green screen after it is composited so in the end all the HD is in 720 30P. How hard is downrezzing? 2. How bad is 720 30PN for green screen, do you really need 1080? 3. What kind of 1080 will give me the best green screen -60 i or 30P? |
