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:
The frame rate of your app video preview is too high.
I can't see any options in the QuickTime Player to change frame rate.
Does anybody knows what to do with it?
Videos can be easily converted using ffmpeg, a handy tool that can be installed using homebrew.
ffmpeg -r 30 -i 60fpsvideo.m4v -vcodec copy -acodec copy 30fpsvideo.avi
-r 30. –
Radu This is what worked for me:
ffmpeg -i input.mov -qscale 0 -r 24 -y output_5.mov
-qscale 0 made sure the length stayed the same but the frame rate dropped from 56 or so (as it was recorded from my iPhone6 by the QuickTime) to exactly 24 !!
Then managed to successfully upload to iTunes, yay!

There is also this option to just do it with iMovie: Creating App Previews with iMovie
Just did my first movie. hit lots of snags - heres quick steps to avoid them:
I have followed the following steps :
/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
then
brew install ffmpeg
then used the following command :
/usr/local/Cellar/ffmpeg/3.1.3/bin/ffmpeg -i SpeechToText_usage.mov -qscale 0 -r 24 -y speechtotext_framerate_changed.mov
It worked well!
I found out, that there is no possibility to edit the frame rate in the QuickTime Player.
I ended up downloading trial version of Final Cut Pro. In Final Cut Pro it's just a few clicks.
For Quicktime videos user this command, worked for me fine:
ffmpeg -i demo_app.mov -qscale 0 -r 24 -y -vf scale=1080:1920,setsar=1:1 app_preview.mov
You can fix it easily in iMovie (I used 10.1.10).
1. Go to main screen of iMovie.
2. File -> New App Preview.
3. Drag your movie to the project.
4. File -> Share -> App Preview.
For Quicktime videos use this command line:
ffmpeg -r 30 -i 60fpsvideo.m4v 30fpsvideo.avi
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.
I scripted this into a borne again shell (bash) to convert a bunch of files. You can add 'rm $file' to the script to delete the original file if you wish, but do not do this unless you know exactly what you are doing and take full responsibility for the risks involved. I list 30s in my filename convention to specify the length of the video. If your file name convention is different you will need to adjust accordingly.
#!/bin/bash
for file in `ls *s.mov`
do
newFileName=`echo $file | sed s/s.mov/s_r24.mov/`
# echo $file $newFileName
if [ -e $newFileName ]; then
echo $newFileName "exists"
else
echo ""
# echo $newFileName "does not exist"
ffmpeg -i $file -qscale 0 -r 24 -y $newFileName
fi
done
sh resize_video.sh
This script, will convert videos as needed by the AppStore.
