Tracking ability with a small number of frames

Hi again :) Your work is truly amazing, although, I wonder If model won't be able to work correctly with, for example, 3-5 frame video?

For now, I have an issue when for short sequences I get zero masks and trajectories, scores are -inf.

Could It be a consequence of no object motion?

Hi, thanks for your questions and issues, and sorry for the delay! I've not covered an edge case of CoTracker being given a small number of frames. This should be resolved with this commit. Cheers!
