Mainconcept AVC 720p from Vegas

Right click on clip, Make iPhone/iPad/Appletv version

See in the picture, I did not see 720p
In this way you will move to transfer iTunes to iphone4 without a problem

Click the Custom button next to the Template, modify your parameters as needed and then save this a preset for future use.
There's also the Sony AVC file type which has Internet 1280x720-30p (or Internet 1280x720-25p if needed) presets.

But remain a problem when the video is transferred to the iPhone4 by iTunes does not sync video as said Mike Kujbida
IPhone4 works on H264
