What am I missing here? I've used mask tracking before, although not often, and I don't remember it behaving this way.
I'm on Pr 22.5, Windows 10.
I'm tediously tracking a mask, one frame at a time, making adjustments on each frame. When I go back to the beginning of the clip to watch, the mask is no longer what I drew. ??? In other words, the keyframes appear to not stay the same. The mask is usually a slightly different shape, and moved over to either the left or right. The points of the mask move to seemingly random nearby points. And the part of the video I worked so laboriously to cover is once again visible.
I have tried more than once. The first time I spent an hour on a short clip, and then assumed I had done something wrong, so I tried again. Another hour ish. Same thing. The points of the mask do not stay where I draw them. I don't remember this happening before. It's either a bug, or operator error somehow. I'm open to either, just want to know what's going on.
To be clear: when I go back, I'm not tracking backwards... I'm just moving the playhead to the beginning of the clip to watch what I accomplished. And that's when I see the mask keyframes have changed.
Please help! Thanks in advance.
The amount of nodes need to be the same from beginning to end for the mask.
In other words dont add or delete during tracking.

This answers my problem as well. But that seems strange. I'm tracking a mask over a vehicle that grows in "size" as it comes towards the camera. I guess I'll have a lump of them sitting to the side. 1, 2, 3, 4...

That totally works. Thank you for your answer. Finicky little thing ain't it?
