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)
- MP4 file (mp4, m4v, m4a)
But the app cannot open/play the following files.
- Files which QuickTime Player cannot open
- Files which require any conversion or codec components in QuickTime Player
- Protected video/audio files (e.g. Movies, TV Shows downloaded from iTunes Store or TV app)

Please backup your data before using this app, just in case an unexpected error occurs.

・Added keyboard shortcuts for changing play speed
 J: Speed down
 K: Normal speed

Nice alternative since iMove 10 does not support Chapter markers - This App provides an easy way to add Chapters to iMovie videos now that the latest iMovie no longer supports Chapter markers. You just open the exported iMove file with mChapters and add Chapter(s) at any point you wish. However, iMovie’s exported file has the mp4 extension and the old Quicktime programs like iDVD and Quicktime Player 7 do not recognize chapter tracks in an mp4 file. From the Finder simply change the extension from mp4 to m4v before or after editing with mChapters and the chapter track will be recognized.

Application not responding - Well… another one has taken my money. This app was purchased, I clicked on the icon and a box popped up for me to load in the file. i choose the file and it hangs there. Outside of the pictures within the app store, I have not even seen the app, menus or buttons. I would steer clear if I were you. Do not purchase this non-working app.

Review by Acurina

Just Works! - After constantly looking for a simple way to add chapter markers, this app is a breeze to use. I love the 5 and 30 sec jump forward/back functions. Never corrupts my file on save. One feature I would like to see added... ability to zoom in/out the time line.
