PRESET:
Select any of the non-legacy built-in presets. Normal, High Profile, AppleTV, and Universal are all decent choices, although I would stick to the first 2.
RESOLUTION:
When using Normal or High Profile, if your source is higher than standard resolution (more than 576p), then you have to scale down to screen size. You can see the source resolution at the bottom of the main window, labeled "Picture size: Source:". In the picture settings, make sure the Anamorphic menu is set to "Loose" or "Custom" and lower the width (not display width) to 1024 or less.
FRAMERATE:
If your source framerate is greater than 30fps, you're going to have to lower it. Generally this is going to be an fps like 50 or 59.9, so halve it to 25 or 29.97. You can see the detected source FPS in the activity log, it looks like this:
Code: Select all
[14:23:00] scan: 10 previews, 1920x1080, 23.976 fps, autocrop = 0/0/0/0, aspect 16:9, PAR 1:1
AUDIO:
If you use the High Profile, AppleTV, or Universal presets, you can remove the AC3 pass-through audio track if you know you'll never play the video anywhere but the iPad.
C'EST FINI
That's it, you're ready to encode.
