I have a problem with masking, which I can't solve:
Let's say I have a mask and animate it.
And after a few frames I want to delete a few vertices from the mask because they are no longer needed and in the way.
The problem is: If I delete a vertex from the mask (doesn't matter in what frame) the vertex gets deleted in all other frames as well.
How can I independently delete vertices in a mask on one frame without affecting the other frames?
In After Effects there's the possibility to uncheck "Preserve constant vertex point count when editing masks".
And Vegas solves the problem by using a totally different way of masking.
Is there a way to do that in Hitfilm (without using multiple masks) ?
