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:

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
