It's worth mentioning that if I disable sync to vblank, the behaviour is much smoother. A few dropped frames, but much less visible. Furthermore, if the framerate of the video I'm redirecting is not too high (let's say half of the display refresh), the animation is smooth. I noticed the choppy behaviour when displaying 60fps video, and my display refresh is 60. I can speculate as to what's happening here: when clutter gets the damage event, it uploads the new texture from the updated pixmap and paints it immediately, rather than also processing whatever behaviour steps might be pending in any active timelines.
