The text data of chapter marker titles are stored in a text track. To create a new text track, do one of the following.

• Choose Markers > Add Text Track, a new text track with a chapter marker at the beginning will be created.
• Choose Markers > Add Text Track with Markers..., the sheet to create a new text track with chapter markers will be appeared.

You can add multiple text tracks for each language.

To make a text track work as chapter markers, makes the track is referenced as chapter by any one of the tracks.

The text track is referencing itself as the chapter-track.

You can choose a chapter with a menu or pop-up button. It depends on a movie player. The below is the controller of QuickTime Player. The chapter selection button appears when recognizing chapter markers.

macOS 11 or earlier

macOS 12 or later

There is no difference in the usable characters between track languages. You can use unicode characters in any language settings.

If a file has one or multiple text track for chapters, which one used is dependent on the system language settings and movie player apps. The apps of Apple also have the following differences.

The priority language of the text track to use as chapters.

• QuickTime Player version 10.5 (1110.4.21)
  1. The language(s) listed in System Preferences > Language & Region > General > Preferred languages
  2. "Unknown Language", if there isn't any language that matches the above in the file.
  3. No chapter shows, if there is not also an "Unknown Language" in the file.
• Music version 1.2.0.273、TV version 1.2.0.273
  The language of the 1st text track in the file, regardless of the system language.
• Apple TV tvOS 15.1.1
  1. The same language of the system.
  2. "Unknown Language", if there isn't any language that matches the system's in the file.
  3. The language of the 1st text track in the file. But the titles are displayed as "Chapter 1", "Chapter 2".
• Music、TV in iPhone and iPad version 15.1
  They does not support chapters.

Especially when it is expected that a movie is watched in various system languages, you should add an "Unknown Language" text track as the following to avoid not showing chapters.

The time coordinate system of MOV/MP4 is managed by two integer values, Time Value and Time Scale. Each movie/audio file has its own time scale. Time Scale is not editable. It is set appropriate values when movies created. A time is represented by as follows.

(Time Value) / (Time Scale) = seconds.

For example, a time scale is 600 and a time value is 1200, it means 2 seconds. If the time value is 1500, it means 2.5 seconds. See also below.

e.g.1) Time Value: 2,160,000 Time Scale: 600
2,160,000 / 600	=	3600 sec
	=	60 min
	=	01:00:00.000
e.g.2) Time Value: 171,488,056 Time Scale: 44100
171,488,056 / 44100	=	3888 and (27256/44100) sec
	=	64 min 48 sec and (27256/44100) sec
	=	01:04:48.27256

You can see a time scale of a movie at the duration time display at the bottom-right of a main window. It's clickable to change display styles in the following order.
1. Time Value/Time Scale
2. hh:mm:ss.xxx/Time Scale
3. hh:mm:ss.xx (xx is centi-second)

Double-click a chapter marker time you want to edit.

Double-click a chapter marker title you want to edit.

Drag and drop the time counter button to a chapter marker you want to replace on the Chapter Marker List.
Or select the chapter marker, and then choose Markers > Replace by Current Playing Time.

You can add chapter markers by importing a text file contains times and titles formatted as mChapters, QuickTime, or Vorbis Chapter format.

To import:
Choose File > Chapter Title > Import..., and then select a text file. Or drag'n'drop a text file to the window.

These text files must be in UTF-8 encoding and plain text with extension txt.
Subsecond value in all formats must be between 0 and less than a value of time-scale-value.

• <@TimeScale:44100>
  Specifing the time scale of timecode. It's an optional element. The default time scale is 100.
• <@Start>, <@End>
  All markers must be between them. Any lines before and after them are ignored.
• Each marker must start with a timecode value in the format [hh:mm:ss.xx]
• After the timecode value, you can include a title for the marker. You can separate the timecode from a title by a new line.
• Timecode: [hh:mm:ss.xx]
  It must be start with a left-square-bracket [ and end with a right-square-bracket ].
• Chapter Marker Title:
  New lines "line break code" and space/tab characters before and after a title will be removed.
  A character [ "left-square-bracket" is the key text of timecode. If you want to use it in a title, you must write a backslash "\" before it.
  e.g. [ABC] ⇒ \[ABC]

Example:

• It begins from {QTtext} and then {timeScale:xxx}. xxx is a time scale value. (required)
• Timecode: [hh:mm:ss.xxx]
  It must be start with a left-square-bracket [ and end with a right-square-bracket ].
• Chapter Marker Title:
  It needs a line feed between a time code and a title.

Example:

• Timecode: The time scale is 1000 fixed. A subsecond value must be from 000 to 999.
  CHAPTERxxx=hh:mm:ss.xxx
• Chapter Marker Title:
  CHAPTERxxxNAME=Chapter Title
• xxx of CHAPTERxxx and CHAPTERxxxNAME must be a same chapter number.

Example:
