Unable to load video / An error occurred while loading a higher-quality version of this video

I am having the same problem

I am also experiencing this issue, videos that I have created in final cut pro and added to the my photos library, are now receiving the error message Unable to load video / An error occurred while loading a higher-quality version of this video. This is accross multiple phones and users as the videos are also in a shared album.

Your iPhone maynot have enough space to store all high-resolution photos and videos from iCloud.

Please compare 

Settings>your name>iCloud>Manage Storage

And

Settings>General>iPhone Storage

This will give you a fair idea of how to manage your device storage.

Some of the links below may help

Well i gotta update on this one.. so finally Apple engineers did their thing.. and all my videos that has this problem are gone… forever. Well i can still play them if i send them to some1 but basically they said theres nothing they can do about it… so like said this is very bad problem… I had like 4000 videos on Icloud. Now about 1000 on them works.. I’v had Iphone since iphone 4… so I’ll hope you guys can get your videos back, for me it didnt work… sorry my bad english, i hope you get my point from this..

Hello fellow iPhone users, I’ve found the solution to everyone’s issue.

• Select the video you wish to play.
• Next after you get the unable to load video message press ok.
• Next you want to click edit video from the top right corner.
• You’ll then see the video being downloaded.
• Lastly click cancel and enjoy your video. (Make sure you have storage cause otherwise it might not work)

Yes, I have done the same - they sent me a link to report to the Photos team. They seemed to accept it might be an issue, but then by faith was tested when he said 'and we will release an update to iOS'. I reminded him it was Mac, iPhone, iPad, Apple TV....... :-). It is reported though.

I am having the same exact issue and I have tried everything. It actually just seem to start when I upgraded to the iPhone 15. It only happens to videos from the GameChanger app (which is sports videos) The videos in my Album but when I uploaded them to a Shared album for my kids, the error occurs and can’t view the video. Frustrating!

So, paying for 1TB of iCloud storage and also running into the annoying problem myself, I have an even better solution (bandage) for thus problem. When you see this error, it means one of the photos used in the memory does not have its high quality version not fully downloaded from the iCloud database. In my case, the Xmas memory that was auto-created had this issue but I could not simply duplicate the video and replace it as the memory itself wouldn’t allow me to add other photos to the set. So:

1. 3 dots, upper right corner of the memory.
2. Select Manage Photos, and select / deselect every photo / video and spot the ones with a mini cloud icon on the bottom right corner of its thumbnail. This means it is not fully downloaded from iCloud (or at least its not marked as such in the photo app’s registry due to a bug).
3. Long press media with the icon and Show in All Photos.
4. Go to media and select Edit.
5. Go to the trim function and trim 1 second of it from the end. Save Video.
6. Edit it again and set the trim back to full length.
7. Now iCloud has marked this media in its registry as fully downloaded from iCloud. You should be able to download the memory now and share as normal.

They are working again this morning!

I am still currently having the same trouble with my videos and even deleted them to restore. Apple can you fix this because this is nerve-wrecking.

yes! I just checked and it indeed seems that the problem is with h264 videos… tomorrow I’ll call them…

Nope. They can’t fix this. I have contacted apple support about this…

Here is your solution go to the photo/video that will not load and tap the edit button in the top right from there it should load and fix your problem.

I found a fix after trying EVERYTHING including restart, iOS update. What worked was changing the format option on the video from automatic to current or most compatible. It's a bit tedious to do individually, but I am happy I get to see my old videos again!
