Screen video grab -> macOS App Preview at 30fps

I am trying to add a video preview for a Mac app on App Store Connect, but I have run into a frame rate issue.

  • I use macOS's screen video capture feature
  • Drop the video clip into iMovie
  • Add a blank soundtrack because App Store Connect rejects it without a soundtrack
  • Export the video
  • Upload to App Store Connect.

But then App Store Connect rejects it because of the frame rate (it is 60 fps). App preview specifications says max frame rate is 30 fps.

I can't seem to change the video capture on the Mac to 30 fps. I can't seem to export from iMovie at 30 fps.

Am I missing something?

Do I need to buy Final Cut Pro to create 30 fps video? If so, can I do it on Final Cut Pro for iPad (which seems much cheaper than FCP on Mac)?

Are you using File -> New App Preview?

Current work around

  • Shot a few seconds of video on iPhone at 30 fps
  • Exported video to file system
  • Created new iMovie project
  • Added iPhone video to iMovie project first
  • Added screen grab video after it
  • Added blank sound track to screen grab portion
  • Deleted original iPhone video from project
  • Export video from iMovie

Video has a frame rate of 29.97 fps (yay)

Progress, but new error: "Your app preview is too large"

From QuickTime Player Inspector:

  • Resolution: 1920 x 1080 (which matches requirements)
  • Current Size: 3456 x 1944 (in QuickTime Player)
  • Video size: 21.6 MB (I thought this was within requirements)

Still working on this... (ah, exceeded 30 second maximum length)
