Questions on camera settings for big green screen shoot.
on Jan 22, 2019 at 1:43:56 am

Hello all, I am not sure which other forum to use for this question but this is the only one that I have had personal experience with help so Id figure you would help me. ☺

I have a big green screen shoot in a few days that involves over 15 of my classmates to be individually shot in the green screen studio. This is a very tricky thing that I am doing since for years Ive had great luck with filming on the green screen and horrible luck happen as well depending on so many factors that could mess it up. I am filming each person on a Panasonic 4K AG-UX (Which is a very tricky camera due to the extensive amount of settings). Ive taken a look in many websites for tricks to achieving a perfect green screen quality. Many websites have explained that the lowest ISO possible to not have grain, and a high shutter speed to not have motion blur will be substantially good. I have a question about the frame rate.. I have a choice between 59.94P, 29.97p, 24.00p, and 23.98p..The final video itself would be 30p, but if i wanted to have a nice slow motion of them posing would I be better off using the 59p? I know premiere pro's optical flow would make that very easier for me but I am trying to make this shoot as perfect as can be. I was confused about that as some websites said things about interlacing issues and things like that filming a 59p on green screen, would you mind giving me your thoughts about that? Thank you so much for your time. I was planning to do a test shoot in the studio the day before the shoot.

I have a general idea of how i need to light it, ive read that the way you light your green screen Will make or break your shot in editing though.

Here are some take-'em-to-the-bank tips for green screen lighting & setup:
  • No green on the subjects! This ought to be a no-brainer. Sadly, it isn't.
  • Separate lighting for the subject and background -- don't cheat on the lights. If you need more, get more.
  • Background needs FLAT lighting -- no dark or bright spots. Uniform.
  • Background should be darker than the bright spots on the subject. In general, subject should be brighter than background.
  • Place subject at least 6 feet from background to reduce light spill, preferably more distance. If this makes the background too small, get a bigger background.
  • Backlights on the subject are good. One trick that really helps is a backlight with a little magenta gel.
  • RUN TESTS! Know that your setup will work BEFORE you shoot for real!
Hey, if this is a big-deal green screen shoot, you want to give yourself the best chance to pull a good key. You want to fudge? You're rolling the dice.

Use as much of this advice as you want. It's your head, not mine!
