quicktime player "export as" black screen with Audio only

Hello,

I used Quick Time Player to edit screen recording videos taken by Ipad pro. When I trimmed the Mp4 video and choose "export as", it has no prob. But when I did "split clip", deleted some clip part , then I only got black screen with only audio when "export as" new video.

I tried with other screen recording videos taken by mac, there are no problems. No matter I split clip or trim with Quick Time Player, I got videos I want.

The problem is that I only got black screen videos when edit screen recording videos taken by Ipad Pro with Quicktime Player. Any ideas on how to solve this problem? Thank you very much.

MacBook Pro 13″, macOS 10.15

Just want to correct, when I trimmed the screen recording video from taken by Ipad pro and export it as new video, it's still black with audio only. If I "save" the trimmed video instead of "export as", I see the video.

I called Apple support and it was dealt with for about 3 hours. I was told to try under new account name, reinstall macOS Catalina, and it didn't work.

I missed the representative's call checking in if it worked after reinstall macOS.

Don't know how this will be solved. Why does this only happen to the screen recording video from Ipad Pro?

Thank you

Just to update,

I called Apple support again. Another adviser helped me with is issue.

According to him, it is a compatible issue. The dimenstion of video from Ipad pro is 1440 × 1920, which can not be converted to .mov format like regular MP4 video whose dimension is 1080 × 1920. Instead he advised me edit the Ipad video with Imovie, which worked out.

A thumb up for this Apple Adviser, professional, patient and effitient~
