and

what click?

thank you!

The end of the video was probably a jump to where I had tracked it in Manual mode. This was an editing mistake, not an option you can use in mocha.
Normally with Manual track you just have gaps in the keyframes unless you have used the tracker before or during using Manual mode.

Thank you for your answer.
