I am using Camtasia Studio 8 on Windows. I have created a video (for my client) that will be on the App Store and Google Play. I know I need to create an MP4, but can someone give advice on which MP4 format I should choose? 480, 720HD, 1080HD? Also, do I choose with the Smart Player, or without? My clients said it needs to be the "format for landscape iPad".
