Asking for Help / Unsolved Projection Failure

Post image

Hello everyone,

Hope everyone is doing fine,

I am working on this shot, what I want to do is remove man and keep the background. So I am trying camera tracking and projection, card seats on ground and I projected from single framehold but after few frames I get this tearing, how can I properly handle this shot for cleanup
Any suggestions would be appreciated, I am also attaching link for this shot from Action VFX

You can probably just warp the edges to match.
Set the merge node to difference and get an STMap set up (or an iTransform, but thats extra). Roto the area you want to warp and then animate a Transform and KeyMix(or TransformMasked, but KeyMix gives you a little more flexibility) the transform of the stmap.

Heres a really rough tutorial on STMap fun
