Function: Examines a track and sets up aperture mode dimensions.
Notes: This function can be used to add information needed to support aperture modes to tracks created with applications and/or versions of QuickTime that did not support aperture mode dimensions. If the image descriptions in video tracks lack tags describing clean aperture and pixel aspect ratio information, the media data may be scanned to see if the correct values can be divined and attached. Then the aperture mode dimensions are calculated and set. Afterwards, the kQTVisualPropertyID_HasApertureModeDimensions property will be set to true for these tracks. Tracks which do not support aperture modes are not changed.

QTTrackMBS.HasChapterTrack as boolean

method, QuickTime, MBS QuickTime Plugin (QTMovie), class QTTrackMBS, Plugin version: 8.5, Mac OS X: Works, Windows: Works, Linux x86: Does nothing, Feedback.

Function: Adds an empty segment to a track.
Notes:
self:
The track for this operation. Your application obtains this track identifier from such functions as NewMovieTrack and GetMovieTrack.

time:
A time value specifying where the segment is to be inserted. This time value must be expressed in the time scale of the movie that contains the destination track.

Duration:
A time value that specifies the duration of the segment to be added. This time value must be expressed in the time scale of the movie that contains the destination track.

Return Value
See Error Codes. If you try to add an empty segment beyond the end of a track, this function does not add the empty segment and returns a result code of invalidTime. Returns noErr if there is no error.

Discussion
You specify the starting time and duration of the empty segment to be added. These times must be expressed in the movie's time scale. This function then inserts the appropriate amount of empty time into the track. The exact meaning of the term empty time depends upon the type of track. For example, empty time in a sound track is silence. Note that you cannot add empty space to the end of a movie or to the end of a track.

Lasterror is set.

QTTrackMBS.InsertTrackSegment(dest as QTTrackMBS, srcIn as integer, srcDuration as integer, dstIn as integer)
method, QuickTime, MBS QuickTime Plugin (QTMovie), class QTTrackMBS, Plugin version: 8.5, Mac OS X: Works, Windows: Works, Linux x86: Does nothing, Feedback.

Function: Copies data into a track.
Notes:
self:
The source track for this operation.

dest:
The destination track for this operation. This function places a copy of the segment, which is obtained from the source track, into this destination track. The media for the destination track must be opened for writing by calling BeginMediaEdits in order for the data to be copied. If the media is not opened for writing, the segment will be copied by reference. At the end of the editing session, your application must call EndMediaEdits if it has called BeginMediaEdits.

srcIn:
The start of the segment in the source track. This time value must be expressed in the time scale of the movie that contains the source track.

srcDuration:
The duration of the segment in the source track. This time value must be expressed in the time scale of the movie that contains the source track.

dstIn:
A time value specifying where the segment is to be inserted. This time value must be expressed in the time scale of the movie that contains the destination track.

Discussion
If you are copying data between tracks, make sure that the two tracks are of the same type. For example, you cannot copy a segment from a sound track into a video track. If you have assigned a progress function to the movie that contains the destination track, the Movie Toolbox calls that progress function during long copy operations.

Special Considerations
If you copy a segment without calling BeginMediaEdits on the destination track's media, the data can be copied later by flattening the movie.
