MP4 Video will not transfer to my iPad
I created a movie using Adobe Lightroom 3. It creates an MP4 video file. It plays in iTunes and all my other video players. However, when I try to synch to my iPad I am told that the file was not copied to my iPad because the file will not play on it. I have a 32gb WiFi model iPad. I tried using iTunes to convert the file for use on the iPad but it tells me that the file is already in the correct format. I am a bit confused. Everything seems to have been done correctly. Is there a particular resolution that must be adhered to? The file I created is 720 x 480.Any help out there?
