I created a view for APP preview in the App store. Here is my configuration in the final cut pro:

Final cut pro screenshot

But i got this error constantly 

Your app preview is in the wrong format. For more information, see the Developer Help.

Then I found this website and I set this configuration there

https://video.online-convert.com/convert-to-mp4

Video bitrate: 10240

frame rate = 30

Audio Quality = 256

But I got the same error.

Then I bought this app in the Mac App store

https://apps.apple.com/de/app/app-preview-video-converter/id1137451860?l=en&mt=12

But the output video from this app got the same error as well.

I worked many hours on fix this problem, could anyone help me to how to save my app preview video?

It seems theres a bug somewhere in App Store Connect at the moment. Your video format looks good so this must be what you are experiencing.

I am still waiting for it to be fixed and haven't had any success for at bit more than a day now - just checked again.

See related post on apple developer forums here: https://forums.developer.apple.com/thread/120816

Edit: It seems the error has been fixed now. Mine is working and so is it for the users on the related post

  • I have the same issue since more than 24 hours now. It really seems to be a Bug currently on the App-Store connect. Screenshots upload well, but every Video (App-Preview) fails in the moments I click on save. Then I checked it with a other app which is in preparation, and I used even a month-old video I used already for another app - with success. Nothing works for the moment. Every Video in every format ends currently up with the message: "Your app preview is in the wrong format. For more information, see the Developer Help." - Hope Apple takes care soon... voilà – ZAY Aug 05 '19 at 11:29
  • thank you so much for sharing your experience. I was worry about my videos. – Jon Aug 05 '19 at 20:07
  • I confirm, that App-Preview video upload works again - nice! – ZAY Aug 07 '19 at 08:27

I had the same problem since yesterday. So I ended up submitting my app for review without the preview. Today it was reviewed and appeared in the App Store. I immediately went into iTC and instantiated a new version of the same app. Previously submitted screenshots showed up. I dragged the Preview video I had no luck submitting yesterday... and... it was accepted! With no error message!!! -_-;;

So here is the strategy you can use if you really want to submit the Preview:

  1. Submit the current "unlucky" version for review. Optionally you can set it to be released manually.
  2. Wait until it is reviewed and flagged as 'ready for sale'.
  3. Instantiate a new version.
  4. Add the Preview by dragging it into the screenshot drop area.
  5. Archive, upload the new version; draw the rest of the owl.

Also make sure that the Preview you created meets the requirements. Hope it helps.
