thanks. tha'ts a lot of data and more than I can handle. My output options are simply .mp4 and these choices:
320 x 240
420 x 320
720 x 480
960 x 540
720p and 1080p don't work. Will one of the others?

thanks, i will do that and let you know what happens.
I did import it into iTunes, but when i tried to sync it to my iPad iTunes refused because it said the video wouldn't play there.

no idea if any of this will help. I have no familiarity with the program.

Here's a shot in the dark. And I don't know if hte program will open them, but there are free programs, handbrake and mpegstreamclip. both of them can convert video for iDevices. If you get it out from your lightroom, see if either of those can open it, then use them to convert the MP4 and see if iTunes will open it then.

well, i got it to work, but i really don't know why. I tried all kinds of different sizes.
for some reason 960 x 540 works. 720p, 1080p, and 720 x 480 all wouldn’t.
thanks again for your help. much appreciated.

You need to set the H.264 level to 4.1 or less. It's very easy if you have access to a Mac (using Subler) and a bit more time-consuming on a PC. See http://www.iphonelife.com/blog/87/making-stock-videos-application-play-every-mp4 -files-possible for a tutorial (the Subler tutorial link is at the end)
With this trick, you'll be able to sync even 1080p videos to your iPad.

You will only encounter playback issues with non-native file container formats (MKV, AVI, MTS, WMV etc.) played from third-party players. MOV / M4V / MP4 files, assuming they have proper H.264 AVC (or ASP) content, will play back just fine, even at extreme bitrates.
For example, the standardized 40 Mbps (!!!) test video stream at http://www.auby.no/files/video_tests/h264_1080p_hp_4.1_40mbps_birds.mkv plays just fine with the original (24 fps) framerate on ALL A4- and A5-based iOS devices after remuxing it to a MP4 container. For that matter, even the old iPhone 3GS plays it back at a tolerable speed.
That is, all you need to do is sticking with H.264 and MOV / M4V / MP4 containers - that is, avoiding non-native containers and/or stream formats. Then, you surely won't ever encounter framerate issues, not even with 1080p content playing back on A4-based models like the iPad 1 / iPhone 4 / iPod touch 4. (Of course, you need a third-party app to sync these 1080p files to as iTunes, however much the device would easily be able to play back the files, refuses to sync them. As was also the case with the iPad 2 before the iOS5 times, BTW.)
