Speeding up the footage - How to do it correctly

Hello everyone,

Next month we will be shooting a scene which would be sped up in post. A scene where the character would be near normal speed and everything else would be sped up. No green screen, right now we are operating under the assumption that we will just have the actor be very still and sort of slowed down while everyone else would move around him at normal speeds.

here is whats going on:
- Enface / Character standing statically in the center of the frame amongst the fighting warriors.
(shot in 100fps)
This is the example of what I would like to achieve:

Please let me know if there is a better way of doing this or if we are indeed right about the method.

Thank you,
you are The Best

The green screen is your friend!

Question, are you wanting everyone but your lead to be faster or slower?

If you want a fast-moving scene, you won't need 100FPS for that. You could easily shoot in 24p with a high shutter speed and speed the footage up in post. Your directions for the actors are right though. Lead moves as slow as possible, everyone else moves as fast as possible.

Another possible option if no action crosses in front or behind the lead, you could use a mask or two to layer multiple speeds of footage similar to how one might "clone" an actor. Strongly suggest a couple of test shots before your actually shooting that scene if possible.

Thank you =D, I will proceed to test shots, I think that the mask way would be better but since I wont have dolly I probably wont do this. It will be shoot in quiet chaos on an event...
