Thumbnails on videos sometimes not working on Iphone
We MUST have a certain thumbnail on videos. We added through various steps:
- Add it as an image for the first seconds of the video
- Select it as favourite frame on the video using Mack and QuickTime Player
- We also add it on to the video's description as an icon (save as png and pasted it there)
We then airdropped the videos to an iphone 12 (IOS 18) and tested the videos and the thumbnail was always there.
Then, days laters, only a few videos had the proper thumbnail and then others didn't. The videos who didn't have it, have the same screen size, and same thumbnail size.
We tried restarted the phone and the video seems to randomly choose the thumbnail. It is not even the beginning or the end of the video.
Any tips?
iPhone 14, iOS 16
