Time Base Functions / Working With Time Base Values

SetTimeBaseStartTime

You can set the start time of a time base by calling the SetTimeBaseStartTime function. The start time defines the time base's minimum time value. You must specify the new start time in a time structure.

pascal void SetTimeBaseStartTime (TimeBase tb, 
                                    const TimeRecord *tr);

tb

Specifies the time base for this operation. Your application obtains this time base identifier from the NewTimeBase function (described on page 2-297).

tr

Contains a pointer to a time structure that contains the start time value.

DESCRIPTION

Do not use this function to restrict the Movie Toolbox to a portion of a movie--use the SetMovieActiveSegment function (described on page 2-121) instead.

ERROR CODES

None

SEE ALSO

You can determine the start time of a time base by calling the GetTimeBaseStartTime function, which is described in the next section.
