I have a video from my dashcamera and I want to blur a licenceplate of the car in front of me. The distance between cars changes, and the apparent size and location of the car/plate on the screen changes.
I am trying to use the motion tracker to track that plate and it's all over the place. It doesn't track the changes in size or position, it kind of tracks the object... but not very convincing. Error of tracking is too big.

Did anyone had success with this? Is there something special to do to keep this tracking tighter?

Do any of the suggestions here help?

I've found it best to stop as soon as you notice the tracking slip off, recenter the tracker then continue. There's also a frame-by-frame adjustment available if you need to tweak just a few frames
