App Preview to Long

I am trying to upload an App Preview to App Store Connect for a macOS app. I created the preview using iMovie as an "App Preview".


When I try to upload the app preview I get the message "One or more of your app previews are too long".


The preview is 4 min 48 sec. It is 208 MB in size. MP4 format.


I see in the requirements for app previews that they that must be under 500MB, which mine is. I don't see any limitation on the length of the preview.


Any thoughts?

From https://developer.apple.com/app-store/app-previews/


"You can have up to three app previews for each language your app supports, and each preview can be up to 30 seconds long."

Thanks so much. That information was not the the App Preview Requirements page you get when clicking the ? next to the previews. All I could find was a size limitation.
