[Malevolent Rainbow]

Okay so now i have a new problem my mask is not changing shape on mask tracking its staying the same last change i make on each frame can someone please help me should i just uninstall after effects and reinstall?

It looks like you only have one keyframe for the Mask Shape.  

For the Mask to change shape we meed at least two keyframes.

After performing a Track Mask (Animation > Track Mask), we should see multiple keyframes - one keyframe at each frame.
