I don't really have a vfx background, and it would be fantastic if you could help me out! Attached below is a still (and a link to a video) of what I am trying to achieve. I'm looking to shoot a music video that uses forced perspective (mainly band performance stuff), and I am not quite sure how to go about making it look right. To give a little more context, I'll be shooting with an A7sII camera. My questions are as follows:
1) Did they use a green screen for the people?
2) How do you make the person match with their background? I know lighting is a huge part of it, but I'm referring more to field of video, camera angles etc. Is there an equation that involves the height of the person/building, camera focal length etc.
3) Some of the shots in the video are moving... Is this a fake camera move done in post? Was there a lot of compositing involved? Can this be done practically without heavy post work?
4) I've read that if you're trying to make a person look large, you should film them in slow motion to give the illusion of a large body moving. My question here is with my camera's sensor constraints: I would like to shoot the back plate in 4k for maximum sharpness and better grading (shot full frame), but if I film the individual in slow motion, I'd be working with the equivalent of a super 35 sensor. How can I reconcile the two images to make sure that they visually match?
5) Say I shoot a scene that is back lit: I would have to incorporate the shadow of the person in the shot. Any tips?
6) I need to do this on a small budget: Any tips on achieving a good product cheaply would be greatly appreciated!
I know I asked a lot of questions, but I'm having a difficult time finding the information I need online. Thanks for your help!
