MPEG-4 Audio Layer (M4B) is the file format that stores audiobooks and podcasts, primarily those that are available on iTunes. The cool thing about this file format is that, unlike MPEG-Audio Layer III (MP3), M4B can store digital bookmarks. This feature allows readers to pause and resume later, just like a physical bookmark in a printed book!

3GPP (3GP) is a multimedia container format designed for third generation (3G) universal mobile telecommunications system (UMTS) networks, which is a global system for mobile (GSM) standard. Since UMTS is a technology for mobile, the 3GP format allows mobile phones on UMTS networks to capture, save, deliver, and play media over high-speed wireless connections.
The best application for opening 3GP is Apple QuickTime. And although 3GP is designed for mobile, the file format opens easily on most operating systems, including Linux, Mac, and Windows.
3GP is a flexible file format that supports captions and subtitles via 3GPP Timed Text. It does not support interactive menus, but it is compatible with free third-party tools that provide such support. One example is AutoGK. To improve the quality of the video while viewing off-mobile, convert the file to MP4.
