Mask Paths

[Tim G]

How do I set the paths so that I can redraw the mask on every frame, rather than adjusting the original mask?

I don't know that you can. I can't imagine why you want to either, since altering their shape over time is usually the point for moving mattes and rotoscoping.

Depending on what you were wanting, you could create a bunch of adjustment layers with the effect you are wanting, add your masks on each and make each only one frame in duration.

Or, you can try going into your Preferences>General and uncheck the "Preserve Constant Vertex Count when Editing Masks" option. Then you can keyframe and then delete points of your mask from frame to frame which will allow you to effectively "redraw" a mask by deleting the old one first.

Hope that helps.

it is altering the shape of the mask over time, but instead of adjusting the original mask, you can create a new one. I've done it before, there is a button for it, I just don't know how to turn it back on.

May be better to give a description of your end goal. I've never done it differently than what Matt said.

nevermind, i figured it out. I opened up the layer panel on the video and selected "Target:mask 1". now each frame has a newly drawn mask
