Q: Videos can only be imported to iPad but failed to sync with itunes.

This article does not solve my issue.

My problem is: I can import and view the videos by importing them directly from my camera (Canon 5D Mark II). However, it fails to sync when I import them into iPhoto first.

Import from camera:

I have imported videos from my Canon 5D Mark II directly to the iPad using the camera connection kits. It works perfectly. I can view them in Photos and iPhoto (iPad). I can edit them in iMovie and Avid Studio. It works just like those video I took with my iPhone 4S which were synced to my iPad using iTunes.

Sync with iTunes:

However, it fails if I use the iTunes and iPhotos (Mac) to do my job. I imported the photos and videos to iPhoto (Mac) and then put them in an album which is to be synced to iPad. Then, I connected my iPad, started my iTunes and checked that album under the photo tab. After that, I pressed "Sync". When sync was finished, it reported to me that those files, which could be imported, played and edited, could not be played on iPad. 

It is clearly a software bug in iTunes. Please fix that.
