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!

As Good as You Could Reasonably Ask

There are a bunch of movie chapter editors in the App Store. I passed over several due to reviews or feature descriptions. This one looked good, and I’m here to report that it *is* good. There are two key things this app does well:

1. The controls work well. Everything is smooth and crisp. This makes adding chapters very quick.

2. It writes the new chapter track in-place very fast. Other apps will re-write the whole movie instead of writing just the chapter track, and may insist on writing to a different place on disk, which is a pain if you have apps like iTunes that remember where the previous file was. Not this app.

For $5, it’s as perfect as you could ask.

Love this app, just one suggestion!


This is a well made app for adding chapters to video or audio files, without re-encoding so there's no loss in quality.
The only thing I ask for is that we are able to import chapter lists in either .txt or .chp format, so that we wouldn't have to enter each chapter mark manually.
