As for your other question, I'm afraid I'm not aware of any way of rotating bezier masks. However you could achieve the same as follows:
Make the track you want to mask (the eyes in your example) the child track of a track containing generated media pure white.
Make the compositing mode of the parent track "Multiply (Mask)"
Everything that is white in the parent track will allow it's child to show through - currently the whole screen.
No the trick is to apply the bezier mask to the parent (white) track.
You could now use track motion on the parent track to rotate the mask. This is only (so far) a half-baked solution as when I tried it the whole 19:6 frame (or 4:3) rotates and anything outside that rotating rectangle is no longer masked but it has potential if it saves a lot of time moving nodes on bezier masks.
