CineApp requires videos in the following format:
800 x 450 (16:9)
Square Pixels, progressive
Bitrate ~= 0.6 Mbps
AAC mono sound @ 96kbps
30fps max, 15fps (can increase quality in some cases)
Of course, you can film in a higher quality format, but for the video files provided to CineApp, use the above format settings.
