I want to animate the mask (half circle) in image editor - by rotating the mask around the cursor placed in the center, but the final animation looks strange.

enter image description here

Is this one of the limitations of the mask keyframe or is there anything that I can do better to create a simple rotation?

(I tried to add the last anchor point of a previous circle in a hope that it will be calculated as a circle shape, but it gave the same result.)

Thank you

    What are you looking to use the mask for? It would be possible to rotate the mask at the compositing stage depending on your intentions. – Ray Mairlot Sep 30 '15 at 16:25

    The reason the rotation looks odd is because each vertex is moving to it's next keyframe in a straight line. – gandalf3 Sep 30 '15 at 19:14
  • @Ray Mairlot: improve my workflow :) I will use it in VSE, I can rotate mask strip there, I just wanted to know if I missed something or it works like that. – vklidu Sep 30 '15 at 19:30
  • @gandalf3: Oh, now I see ... Thank you. So it keyframes control point position. It does not keyframes trans/rot/scale of whole mask. My fault. – vklidu Sep 30 '15 at 19:44

As pointed out by @RayMairlot you can rotate the mask in the compositor by addong a rotate node and animating its values:
