So my crew were filming some pool action witth GoPro and i was doing an 3D Tracking for it. It scans it normaly but when it starts analyze the camera it will fail. I have tried all methods found from google but no luck. I even ran the clip trough handbreak but no luck. Anyone else having this same issue? If yes, how did you fix it? I just gave up with that thing and moved on but now i wanna do it since im bored.
That usually means that there's not camera movement in the shot that can be solved for to create a matching camera.
Upload the video somewhere so that we can see it; then we can give a better idea.
Trying to 3D track water is not going to work. There must be fixed geometry, things that don't move, in the shot. Since the water is always moving there's no geometry in the shot that AE's camera tracker can use to solve for camera position. A single screenshot of your problematic shot would verify my assumptions. Something like this cannot be solved for a 3D camera because there is no fixed geometry.
