I’m adding representation to an issue that I hope is fixed:

for the last couple months I’ve been able to record videos and watch those videos but am unable to share them, whether on instagram, whatsapp, airdrop or imessage. some limited luck saving the same video to the file system and sharing from there

searching this issue is notoriously difficult, and there is one partially related thread on Apple support forums talking about spacial h264 and spacial h265 video codecs further complicated by being wrappers, with something suggesting the latter is the issue, the final post having a bewildered user asking for clarification that the iphone can create videos that even it cant use

I looked in my camera settings and there are soooo many switches and file formats now, that its impossible to know which edge case has been run into, and there’s no reset button to put the settings back to their most compatible

I hope this OS refresh fixed that

note, this only affects some videos and the common denominator is not obvious. all videos are recent and made in the same timespan. some are sharable some are not
