For the following I have found no answer, wether in the forums or the manual, so here I come:
I have basic knowledge of AE and had a basic five day course on Motion. I am trying to figure out if it is possible at all to do multiple tracked masks in Motion, without baking after each mask is done.
Imagine a shot with several people whose identities have to be protected by a blur. Not a circle blur but a blur obtained by tracking a mask that changes shape with time. Mask lets a blured layer of the original shot through.
I've tried it several times and each time I start a second tracking, in a different group, it messes up the first tracked mask.
Is there something I have to do in order to prevent this or is baking each mask the only way to go?
