Just thought I would share how I added video after using imovies and failing to work on itunes connect
step1. use screencast omatic to record video
step 2. download MPEG Streamclip, import video you recorded
step 3. shorten video to no more then 28 seconds use i to setup your in and o to setup your out trimmings in mpeg stream clip.
command T to trim, export to mpeg change to your desired size eg: ipad 900x1200
now you're good to go upload to itunes connect and your done
it took many hours to find out this so maybe helpful to others lol
just in case you haven't done video you need to use safari to upload or you will get an error and it must be recorded using a mac, not a pc. don't use imovies...
