Tracking shot into a frozen object against a moving background
So i have this visual in mind. Its part of a sequence where a man walks into the frame (there’s traffic moving behind him) and he jumps in the air, freezes in mid-air and the camera tracks into him (could be ramped up). He then unfreezes, drops down and the speed continues as normal.
I don’t have a green screen facility to shoot at so am planning to shoot this real time on location and try and work this out in post.
any advice as to how i can achieve this move?
thanks in advance. -

Does the camera have to move during the shot? If not I think you could have the actor walk in and do a regular jump and you could time-remap it so he slows into a stop at the peak of his jump. You could roto him out during the whole sequence and have the traffic moving the whole time in the background, as long as you shot some footage of the traffic moving the actor not in the frame.

Hi,
If you have the option to stop traffic so there is no movement behind your actor, then you can shoot a clean plate of the background (no actor, no cars, just static scenery) which may help in extracting your actor. Then if you shoot the traffic with no actor, you can then drop it in behind him.

Hey colin,

There are many different ways to rotoscope, and I find that you get the best results from using a combination of a few different methods. I’ll usually draw some masks with the pen tool and animate them around what I am trying to isolate. If im trying to roto out a person, I’ll use one mask for the head, another for the body etc. After this is done, Ill make touchups with AE’s painting tools. Search the archives for “roto” for more advice.
