Hi!! I have a problem to solve. My client want to shoot at an art installation inside a white cyclorama room. He wants some animated type and graphics FX beside people talking to the camera and walking along the place. I can't paint to do a chroma key.

Can I put some trackers to erase them rotoscoping with mocha (p. ex.)?

What kind of trackers on a white background (cross, any color)?

Thanks in advance.

Try to get the same luma. If you don't go into overbrights.
Darker circles for autotracking.
If you want to manually track I suggest a checkerboard pattern in a slightly different color. Then any color will do, as long as you can still see it.

Something like that.
Symetric tracker likes these patterns.

Thanks for answering. What do you mean a bout the exact luma?
