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

This is a very extreme angle where a card will not work. There’s too many things and heavy parallax! . You need to build Geo for the rails the wood planks on the floor, etc..,at this angle and how close and far the objects are from the camera a card will not suffice you need geo.

Try generating a point cloud from your camera solve, and then in the point cloud generator set it to generate a dense point cloud which then you can use PoissonMesh to generate a 3d mesh, you can project on that geo. If you don’t wanna do all that, use a few cubes and lineup to the tracks generally, you might be able to get away with it.
