HTMLVideoElement.requestAnimationFrame() registers a one-shot callback, called after a video frame has been presented for composition. It also provides useful metadata about that frame.

This features allows web applications that use WebGL or <canvas> with <video> to composite at the video rate rather than the display rate. It also allows for reliable video metadata which can be correlated with other page events (e.g. user inputs) and used for automated analysis. It also allows frame-accurate web-platform-tests.
