Thanks for opening this issue! We've seen a lot of these in Crashlytics, but no one has bothered to actually open an issue until now 🎉 I'll look into it.

How was the video encoded? What app did you use to export it?

@chrismessina I'm gonna report this to Apple, but I need to know what app you used to produce the video file.

[chrismessina]

OMG... this was in Oct last year. That said, I believe I was attempting to convert this video to attach it to this post to Product Hunt.

[sindresorhus]

I have submitted feedback to Apple about this. Not much more we can do, unfortunately.
