Adjusting Mocha track

[Marcin Staszewski]

That’s right.
Do you have any specific tutorials regarding this matter (how to properly correct a plane drifting to the side during track) to recommend?
I guess I’m doing something wrong – when I notice the plane starts changing shape I manually put it more or less back to the original, but when I continue the track it doesn’t seem to affect the already drifted track.

There are many tutorials about planar tracking. Firstly, you need to understand the concept of planar tracking and selecting a good region to track. If there are things like reflections or foreground elements you need to avoid this with multiple layers or animating your search layer.

Other tips – increase the % of pixels in the track tab.

View the surface as you track. If it is not tracking well, your search area and what you are tracking is the issue. While mocha can solve really difficult tracks, it is not magic and the user has to feed it good information.

I would recommend following these videos first:

Hi Marcin, Ross has links to videos to help you sort out general issues. If you still have issues, then you may require specific assistance. If so, provide screencaps of mocha’s tracking spline and search parameters. Then, either embed your tracking footage here or provide a link.
