I'm a bit of a newbie here, so there may be something obvious that I'm missing, but here goes.
I'm trying to track a mask for an effect so I start with a mask at time A and click the watch to set a key point.
Go to time B and move the mask and add a key point.
When I go back to time A, the mask has moved, but not the effect.
What effect are you applying the mask to?
Lumetri color, basic corrections,shadows and blacks.
I can't reproduce this. Keyframed masks on the Lumetri effect seem to be working fine here.
Thanks for trying! I'll have to test on another project.
