How to avoid choppy rewind html5 video tag in safari?

Question

JavaScript

Hello! The page has a full screen video added with the video tag. I'm trying to make it so that when scrolling the video is played quickly to the end, and then disappears. To do this, through javascript I set the speed for the video playbackRate=15. In chrome, the video just plays smoothly in accelerated mode, and everything happens as it should, but in safari it is rewound in jerky frames, in fact it shows only 6-7 frames and disappears. The same happens if you specify playbackRate with a value from 2.1 to 15.0 . Any ideas how to avoid this? Maybe there is some kind of adaptation for safari? Thank you!
