So here is the scenario: 1) a Canon 550D Digital SLR (T2i Rebel) latest firmware + 8GB class 10 SD Card 2) a 2010 iMac 21.5" 3.2GHz with latest Mac OS X, iLife 11 (iPhoto 11) 3) an iPhone 4 and an iPad both with latest iOS 4) iTunes latest version I shoot HD videos with the canon camera and take the SD card out of the camera, plug it into the iMac and I import the photos and videos into iPhoto 11 (iPhoto 11 import utility comes up automatically when I plug the SD card in) I move the photos and videos to a new album in iPhoto 11 I connect my iPhone 4 to the iMac and iTunes starts automatically. I make sure the iPhoto album mentioned above is checked to sync with my iPhone. Then I sync the phone. result: the album is synched to iPhone & the iPad but only the photos are copied, none of the videos shot on the canon 550D are synced to the devices. as a work-around. I am able to import the videos into iMovie 11 and created a project then export the movie to 720p HD format and then import that movie back into iPhoto and move it to the album then sync down to the iPhone/iPad! insane round trip I tried shooting in different resolution types (the canon T2i can shoot H.264 .mov HD videos in 1920 x 1080 (HD 30/25/24 fps), 1280 x 720 (HD 60/50 fps), 640 x 480 (60/50 fps)) It just seems like the iPhone 4 and iPad do not support these original HD videos despite the fact that they are stored as H264 and in a .mov file. The workaround I described above is not really a useful or convenient solution. finding it hard to believe all this latest and greatest hardware isn't capable of supporting a simple task like this!? been searching for an answer, but it seems like no one is asking the question. so either the solution must be really simple and I'm over complicating things, or no one has a need to do what I'm trying to do here. Haven't tried pulling the videos off the camera through USB wire instead of taking the SD card out. not sure if that makes any difference. If the iPhone doesn't support those videos period, anyone has a better/simpler workflow? Many thanks help please!
