First H.264 is a video compression codec (MPEG-4 Part 10) whereas MP4 is a container just like Quicktime or AVI and usually associated with different MPEG-4 video compression formats. So an MP4 movie can hold an H.264 codec.
You can have H.264 movie inside of a Quicktime container (.MOV file) as well.

For better compatibility with the internet and devices, today it is recommended to use the MP4 instead of the Quicktime container.
I believe it is true with the iPad as well. If you have Adobe Media Encoder or Compressor, you will find preset for this device and many others.

I hope this help,

Good day.

Are there optimal iPad codecs and sizes, useable on all iPads? Some recommend 1280, others say 1920 is fine. Some say H264, others MP4. Is there any consensus? I don't have an iPad to test with so I'm in the dark. The piece is motion graphics and live action.

Many thanks,

Jonathan
