MCSetDuration

The MCSetDuration function allows your application to set a controller's duration in the case where a controller does not have a movie associated with it.

pascal ComponentResult MCSetDuration (MovieController mc,
                                       TimeValue duration);

mc

Specifies the movie controller for the operation. You obtain this
identifier from the Component Manager's OpenComponent or OpenDefaultComponent function, or from the NewMovieController function (described on page 2-28).

duration

Specifies the new duration for the movie. This duration value must be in the controller's time scale.

DESCRIPTION

The controller's duration remains at this new value until you assign a movie to the controller.

SEE ALSO

You can use the MCGetCurrentTime function, which is described in the next section, to obtain the time scale for the controller.
