I am creating a video archive page for our company's meetings (screen recordings from Teams, downloaded from Microsoft Stream). I download the videos and upload them on the confluence page - they all upload correctly but when you go back to the page ~30+ minutes later, some of the videos are skinny. The 'skinny' version is shown both in edit and published mode and even when you play the video, it plays a 'squished' version of the original.
I went ahead and deleted them all, and re-uploaded them one by one and let them finish uploading before publishing. They all uploaded fine, I even watched a video or two after uploading, went back an hour later and they're skinny again.
Here is what they should look like:
