I match-move a lot of things with the Tracker node but there's 1 thing that annoys me greatly, whenever the thing I'm tracking goes out of frame, the tracker starts jumping around trying to find a new marker. The only way to stop this I've found how to stop this, is to manually hit the stop track button and hope you happen to nail the right frame. Is there a setting to make it so that as soon as the tracker goes out of frame, it stops?

Im having the same problem right now and worse, I'm trying to combine tracks to make one transform path and the experience has become abysmal...

I have TrackerPlus from reactor that has track forward one frame so that's a help to solve the first part of the issue but, now Im trying to combine track data converted to X Y path and the task of moving and combine the keyframe data is just horrible and not even giving a good result for all the trouble.

Of course I don't know your footage or your current approach, but in my experience daisy chaining various trackers is sometimes a lot easier than trying to combine them. If you use the correct order of nodes, there will be no loss of quality because of Fusion's concatenation.

If Fusion loses the track that's not a problem, just scrub through the frames until where it loses the track and delete all the keyframes after that. No reason to precisely hit 'stop' at the right frame. Just fix it and track onwards from the frame where it went wrong. Just choose a new pattern and select 'append track' and you're good to go 9 times out of 10.

The tracker will stop tracking on the Render Out and Render In markers. The yellow lines in the playbar. So if you already know where the point is going out of the frame you can set your markers to the appropriate frames.

I believe this is how the tracker plus makes the frame by frame mode work. It temporarily sets the render range to the next frame and after tracking that frame it sets the range back to the previous range.
