Changing vertex number of masks between frames?

[ryocchin]

Hello,

I have been trying to delete/add vertex to a mask for one frame and not affecting the other frames.

If vertex is deleted from a mask at one frame, it is also delete from all frames.

Is it impossible to delete a vertex at one frame and leave other frames unchanged?

Is there a way to change the vertex number by frame? I appreciate any comments/suggestion

Thanks in advance

OK

OK

Thanks, it was in the "Preferences > General". I found it myself

I got here a bit late it would seem...I'm glad you found it.

However, my recommendation would be to start the mask on the most complex frame and maintain the number of points through out the clip. Things can get a little weird when points start to come and go...

...just a suggestion.
