I make the videos out of Adobe Premiere before (a year ago) and it worked fine but now nothing works.
I've used these parameters listed here https://help.apple.com/app-store-connect/#/dev4e413fcb8
After looking around people have problems with iMovie as well it's not an app thing. I'm stumpped.

For debugging issues.
I've tried most video settings and nothing 100% works. I got one video to upload but it was a fluke.
How did you make the video that did upload? Was it through iMovie or some other app? I'm fairly sure this isn't really a format issue, but if we're going to keep uploading over and over in the hope it finally works we should make sure we used the exact same format as you did!
Have the same problem and sent a bug report to apple - hopefully this get fixed soon!
Did anybody manage to upload previews since this thread started?
My new submission inherited two previews from my last successful release. When I try to upload one of the exact same files once more, it complains that the "app preview is in the wrong format" and does not let me submit. When I remove this newly uploaded file again, it lets me submit, but then complains that I don't have iPad Pro 3rd generation files. I can add images, but cannot save previews.
Did Apple change anything in the preview format requirements?
it was a fluke, one time when I got it to upload. I delete it, reupload, and it doesn't work. Ithink something is wrong with the server.
The problem is still there. The dev team has been quiet on this, not responding. Not sure what's going on.
Same here... still not working. Did you get any answer from Apple?
There must be a lot of people affected by this?!
The same problem here, I contacted Apple about the issue but no answer yet. I'm shure that my video has exactly the same requirements they request !
Yes, specially because this website should be develop for DEVELOPERS by people that know what they are doing... the website is vary laggy, full of bugs, not fitted for portable devices and now this... again..... What a shame apple...
I think the 'wrong format' error is a generic error to deny any uploads. It does sound like a server issue.
Working now! Quick get uploading before it breaks again :/
It now says 'Processing App Preview, The app preview can take up to 24 hours to process'
We had 1 failure since, but 4 others went up prefectly.
EDIT: 2 out of 4 are already processed - so seems to be working normally.
Finally!!! It's working people!!!!
What's your video format? I'm still getting errors. Maybe their update need to reach me on their cloud.
We captured with QuickTime on a Mac, then used file-> ‘new app preview’ in iMovie. Drop the video onto the timeline and then file-> share -> app preview. iMovie creates the correct format for you. If it still isn’t working then iTunes connect is broken again :/
Preview uploads seem to work intermittently now. I needed around 20 tries to upload 9 previews. This is a great improvement on the 0% success rate I got yesterday, but still a far cry from a stable system or the all-clear some posts suggest. The "wrong format" message is wrong and misleading, the same file is sometimes accepted and sometimes not.
