Videos that I look at behave as you describe that that should. But you can view the video normally, is that right? I mean, are you sure that this is, otherwise, a normally functioning video?
- Can you use other editing tools on the video? Like-- can you change the brightness?
- Can you edit non-videos?
- Are you using iCloud Photos?
- Do you have Optimize Storage chosen for Photos?
- How much free storage space do you have on the Mac. Is at least 10% of your storage free?
To narrow things down, try these steps:
- Restart the computer (of course)
- Re-start in Safe Mode. This bypasses certain potentially disruptive processes, and it often helps. Safe Mode is different for different computers, so see this:
Start up your Mac in safe mode - Apple Support
Those are the easiest things to try first. Then try these:
- Use another library if you have one, or make a small test Library with a few pictures in it and see if the same thing happens. You can create a new Library by closing Photos and then option-clicking on the Photos icon.
- Make a new user and see if the same problem recurs with it
- If you're not using iCloud Photos, they rebuilding your Photos Library--close Photos and re-launch by option-command-clicking the app icon. If you are using iCloud Photos, this can take awhile, so hold off.
The idea is to find out if the problem is with the Library, with your account, or with caches and login items, and stuff like that. One of these steps may fix the problem, but their failure to work also helps figure out what's happening.
Let us know what happens…
