Supported formats depend on your iPad model and playback app. An MP4 containing H.264 video and AAC audio is a practical starting point for compatibility testing.
Three Steps to Your Output
Add Your Video
Use Add Media to put the source file into the queue. Check its orientation and dimensions.
Pick Device or MP4 Output
Review a suitable Devices preset, or choose MP4 / H.264 from Video. Keep within the resolution supported by your iPad and the playback app.
Convert, Then Transfer
Choose Save to and Convert. Transfer the output using your normal file-transfer method and try it in the app you plan to use.

If the File Does Not Play
Check the actual codec rather than the .mp4 extension alone. Try H.264 with AAC audio and a lower resolution. A file can be a valid MP4 while containing a codec that the target app does not support.
