Microsoft DirectX 9.0


The EnableTransitions method enables or disables all transitions in the timeline. If transitions are disabled, the render engines treats them as cuts; that is, the rendered output jumps instantly from one track to the next. The default cut point is halfway through the duration of the transition. You can change the cut point by calling the IAMTimelineTrans::SetCutPoint method on the transition. Disabled transitions are not removed from the timeline.


HRESULT EnableTransitions(
    BOOL fEnabled
