I have what I thought was a simple task to do in AfterEffects that is completely stumping me. I masked some footage and then was given a higher res version of the same footage. I need to apply the masks to the new footage and scale them up to match. I can't figure out how to scale all the mask keyframes at once. To my understanding I should be able to select the mask then go to Layer>Mask and Shape Path>Free Transform Points but it only scales the current keyframe. What am I doing wrong? Thanks!
Masks can not be scaled globally,
one way is...
- Copy your mask to a same sized Solid
now use that solid as an Alpha matte on top of your footage
try if you can scale the new Solid (mask will scale with it)
