mChapters is a simple, intuitively and easy-to-use chapter marker editor for MP4/MOV files. Chapter markers will make it easy for users to skip a playing-time to a specific time. It's very useful especially in long duration videos and audios.
mChapters saves chapter marker times and titles as a text track into a file. The text track format is defined by the QuickTime/MP4 specification.
In Mac, you can use them in QuickTime Player, iTunes, Music, TV and other apps which support the format.
In iOS devices, you can use them in apps which support the format. But Apple's Music app and TV app does not support it.
■ Key Features
- Adding chapter markers by specified interval, number of divisions
- Adding chapter markers by importing text file
- Exporting chapter markers as plain text (.txt)
- Fast lossless saving without re-encoding audio and video
■ Supported Formats
- QuickTime movie (mov)

Ratings and Reviews
Excellent, simple and elegant
This was a great addition to my arsenal of video production tools. I have FCP-X for my main editor, but there are times when I just need to do a simple chapter iinclusion and running it through X is tedious for such a simple task. This allowed me to quickly jump through 2 hours of a dance recital, dropping chapters and titles with great precision for over 40 dances in about 15 minutes. SUPER TIME SAVER! Then it saved the file without a re-encode and VOILA! Chapter markers and titles muxed to the MP4 file effortlessly (or very nearly so). Great app!
Simple, works well.
Works GREAT. No re-muxing your video, no manually entering timecodes.... also allows frame-accurate chapter points. Easy add a few chapters at a time to long videos. I edit a lot of concerts recorded from television and meticulous about chatper placement. I can place a few chapters at a time, save the file and continue later.
It's a shame that so few free programs with decent GUIs exist for this sort of task, but for the price and ease of use, this app cannot be beat.
Worked to add Chapters to an iMovie export
Apple hasn't added back in chapters to iMove 10 yet (as of May 2019), and this app did the trick! The brief problem I had was I couldn't figure out how to add chapters at first because the movie did not have a Text track. Once I added a Text track I was able to add chapters, and was able to associate the chapters with the video/audio tracks. Thanks for the very well made app!
