Adjusting Mask Anchor Points
on Aug 23, 2011 at 7:04:55 pm

I'm new to this so bear with me please. I have an object flying across a scene and it's attached to a wire that I have to remove. The wire is not straight. It dangles and bends in various locations. I created a mask with the pen tool and inverted it to reveal a clean background plate. Then I moved the mask via keyframes in Mask Path. I need the shape of the mask to change throughout the scene. But I can't seem to click back into the anchor points to add or adjust them as I need the mask to change as the wire curves. While I've found plenty of tutorials creating masks and moving them to reveal titles etc, I can't find any that adjust the shape of the mask throughout. I attempted multiple masks to get around the issue but then the invert doesn't seem to work once I add on a second mask. Any help would be greatly appreciated. Thank you.

You need to use keyframes to animate the Mask Path property.

I'm using keyframes to animate the mask but I can't click into the individual points to adjust them. I would think this is easy and I'm just not clicking the correct thing.

If you twirl down the mask properties in the timeline and click on something like mask feather, you will have the mask active, but it won't have all the points selected and you can them move the individual points around.
