How to Resolve MP4/MPEG-4 Video Adding Issue in iTunes
by Christine Smith • 2025-10-21 19:54:39 • Proven solutions
iTunes can be considered as the control room of media content on all Apple Devices. If you love watching videos on your Apple devices, you can either purchase them from iTunes or add your local downloaded videos to iTunes library. iTunes supports QuickTime and MPEG-4 videos for playback. The Movie section of the iTunes library shows all your TV shows, music videos, movies and other video content. In simple situations, you can drag and drop the desired videos from your PC to the iTunes library. The added videos can then be synced to iDevices for playback. However, sometimes we'll meet some troubles in adding MP4 (MPEG-4) to iTunes.

Part 1. Why Can't Add MP4/MPEG to iTunes on Mac/Windows
Adding MP4 to iTunes seems to be a simple task, but many times the videos do not get attached to iTunes library and in such situations, they need to be converted to a compatible format. We will discuss situations when MP4 cannot be added to iTunes in the following part of the article.
1. Incompatible Video Codec.
Are you having trouble adding MP4 (MPEG) to iTunes? MP4, as a container format, differs in the video codec. MP4 files can be encoded in a number of audio and video codecs like , MPEG-4, AAC, H.263, and others. On the other hand, iTunes support only a few of these MP4 file codecs like MPEG-4/ and AAC. So, if iTunes rejects your MP4 files, it's most likely the codecs in MP4 files are unaccepted by iTunes. To copy MP4 to iTunes, you will need to convert MP4 files to iTunes MP4 codec.
2. MP4 files are added, but you cannot see them.
After the launch of iTunes 11, all the movies and videos which are not purchased from iTunes will appear under Home Videos of the Movies category. Earlier, these videos were added to My Movies section. Thus there is a possibility that you are not looking for the MP4 videos in the right section or category.
3. Incompatible technical specifications.
If your MP4 file has video and audio codec supported by iTunes, they can be successfully added and played in iTunes. But in order to sync these files from iTunes to iDevices, they need to meet the technical specifications of the devices like bitrate, size, sample rate, and others. So if technical specifications do not match, MP4 files can be added to iTunes, but cannot be synced.
