A timecode media contains sample data that represent a frame number that identifies one or more content frames that use this timecode. This value identifies the first frame in the group of frames that use this timecode. In the case of a movie made from source material that contains no edits, you would only need one sample. When the source material contains edits, you typically need one sample for each edit, so that QuickTime can resynchronize the timecode information with the movie. Those samples contain the frame numbers of the frames that begin each new group of frames

The QTPlgMediaTimeCode class defines a that describes timecode samples. This class inplements properties and methods that allows you to deal with characteristics peculiar to time code samples.







The QTPlgMediaTimeCode class constructors are called when you create a new instance of the class, while the ˜QTPlgMediaTimeCode class destructor, is called automatically when the class is no more in use. Also, you can invoke the class destructor by setting the instance of the class to nil. You can not create a QTPlgMediaTimeCode object by yourself; instead, you will use class instances obtained from objects of appropriate type.
Once a new class instance is returned, it is good practice to check the class property to be sure that the new object can be used. See the validity requirements for more details.

The class provides you with the following initializer methods:
(other as QTPlgMediaTimeCode)
This is the copy constructor. The properties of the object to be copied will be used to initialize the new class instance properties

controls the display of timecode information. If this property is set to true, the timecode information is displayed when the movie is played. The timecode track must be in order for the timecode information to be displayed
identifies the timecode and source identification information for the current movie time and converts this time into a text string formatted as HH:MM:SS:FF. If the timecode uses the dropframe technique (check the property of the appropriate to know it), the separators are semicolons (;) rather than colons (:)
specifies the text characteristics that apply to timecode information displayed in a movie. Not all of the class properties are of interest for this class; the following properties will be set or get:
provides detailed informations about the stored timecode sample data
provides detailed informations about the stored timecode sample data; returns a list of objects
