This is the clip I am trying to use:
In the first section the organism opens and there is a solid contained color I would like to remove to reveal a back layer.
The color of this space is not unique as it should be, is there a way to section off and track this opening?
In my opinion you can do that most efficiently in two ways:
1. Just use masks to rotoscope that place. Movement is really subtle so it should be fairly easy to do it with masks.
2. You can use Roto Brush Tool - faster to setup than method nr. one but more extensive to your processor cores on rendering
