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)

  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.
