i was wondering if anyone has any suggestions to my problem.
I have a video with a pulsing vein, for a second the vein will get slowly visible and then slowly invisible, then again the same. what i want to achieve is shrink the width of the vein. on more problem is that is moving and not retaining a consistent shape.
do i have to go frame by frame and brush it or is there another way. i failed tracking a mask since it moves and fades as well.
any help would be much apreciated.
You could use Mocha to do a planar track of the whole arm, and then apply the planar track to a solid. Then you create and tweak the mask on the solid over the vein on frame 1. Now you've got a tracked mask on the vein that should allow you to do whatever alterations you want to do.
