Do you know why the moon video is disappear in iPhone?

I don't! it's bugging me. I haven't had a chance to look into it. I noticed it in another video embed on another notebook too, so I don't think it's something specific I'm doing. It's also weird that the smaller video works.

aha, seems to be something to do with webm vs. mp4. gotta figure out how to write these <source> tags…

Fixed! required switching to mp4 and setting autoplay on the video for some reason. 🤷🏻‍♂️

If you turn off the autoplay in your Scrubber (autoplay: false) and select a different starting frame (initial: 1000) then it doesn't work in the computer browser BUT works fine in the IPhone :D

Just saw that the above problem is due to the fact that I put the Scrubber inside a html` ` cell

Also, autoplay caused some stuttering on desktop because it was trying to play _and_ seek via the scrubber, so I have to make sure to immediately call `pause()` on the video and let the scrubber have full control.

Yes, somehow the IPhone's browser manages to automatically pause without calling `pause()` - thanks!

Yeah there’s definitely different behavior on the phone. I can see not wanting to auto play or conserve bandwidth and battery on a phone I guess. Though it’s weird we have to include autoplay to seek at all.
