    Mask position and edge issues

    TomGruber Level 1

      I'm encountering a couple of problems with masks in my AE project.  I've had no luck finding any similar problems documented anywhere on the internet.


      I have footage of a man exiting a room through a door, where the room beyond the door needs to be replaced.  I did a basic rotoscope using several masks.  I put a blue solid behind the video layer to help show the issues.


      The first problem is that one of the mask's edges is off.  The mask will not go all the way to the edge of the mask line on one corner.



      The second issue is the mask is completely offset on one frame.




      I can manually move the masks to compensate for this issue, but their borders don't represent what they should be masking.  I'm hoping I may have overlooked something simple.
