HTML5 Video Seamless Looping

Question

I know this question has been asked a number of times, and I\'ve looked through every single one of them here on StackOverflow.

I\'m simply trying to loop a 5 second MP4

Answer 1

Heureka!

We've found the actual, real, work-around-free solution to this problem over at where I work. It explains the inconsistent behavior through multiple developers as well.

The tl;dr version is: Bitrates. Who would've guessed? What I suppose is that many people use standard values for this that usually are around 10 Mbit/s for HD videos if you use the Adobe Media Encoder. This is not sufficient. The correct value would be 18 Mbit/s or maybe even higher. 16 is still a bit janky. I cannot express how well this works. I've, by now, tried the messiest workarounds for about five hours until I found this together with our video editor.

I hope this helps everyone and saves you tons of time!
