Cannot upload video to iTunesConnect: The frame rate of your app video preview is too high

Question

I made an App Store preview video using QuickTime player on OS X Yosemite.
When I try to upload the video to iTunesConnect, I get an error message:

Answer 1

This rescales one video into all the required framerate and sizes to match what App Store Connect needs:

IN=IMG_3518.TRIM.MOV
ffmpeg -i $IN -s 1080x1920 -r 30 5.5.mov
ffmpeg -I $IN -s 886x1920 -r 30 6.5.mov
ffmpeg -I $IN -s 1200x1600 -r 30 ipp3.mov

Don't use this. You should make all your videos by running on the actual different devices. Your account will be banned, your house will catch fire, your cat will die.
