Hi Cameron, thanks for the reply. I managed to get Safari Technical Preview 137 (Safari 15.4) running on macOS Big Sur 11.6. 

I was able to see the first frame drawn in the canvas, but playing the video does not update the frame in the canvas (stays at 00:00 frame). 

Disabling "GPU Process: Canvas Rendering" in STP restores the old behaviour where every requestAnimationFrame call, the video frames are updated in the canvas. 

So the functionality has improved, but still incomplete in the latest STP. Are you seeing the same behaviour?
