I'm still learning how to do video tracking and getting my character to walk within a video scene. I'm having a few problems that are giving me mixed results. For one, whenever I select three of my trackers and select Floor, the camera tilts upside down and goes under the grid, so I can't seem to get my markers to appear in the right place when looking through the camera.
Second, there's an object within the video that's in the foreground. I'm not sure how to get my character to walk behind it without him walking over it during playback.
Thirdly - and this has been giving me issues for a while now - I can't seem to hit a perfect balance on my character's walk speed. I keep messing with Scale, Repeat and the Path's Walk Animation under Data, but can't get a satisfying result. My character either animates too slowly and finishes before the video ends or he reaches the end before the video finishes.
And finally, I've noticed the playback of the video is causing some weird blur/artefacts. I'm guessing this is related to the trackers...? This happens at the top and left side of the video, as though it's being stretched.
I'm at a bit of a loss with this. Can someone help me?
