To offset the scene in time: ■ Select Lock Range Bar To Scene Range. The Scene Start control is enabled but the Scene End control remains disabled: synchronization is controlled by the Scene Start value and the length of the range bar. The Scene Start value is the scene frame number where playback begins. If Scene Start is 0, frame 0 of the scene is the first frame played back; if Scene Start is 12, frame 12 is the first frame to play, and so on. The range bar length determines how many frames of the scene to play. Dragging the end point of the range bar changes the length of the playback range. Although Scene End is unavailable, its value updates to show the frame number of the last scene frame that will be played. Dragging the range bar changes where the scene is played within the final video. For example, if you set Scene Start to 5 and move the range bar to begin at Video Post frame 20, frame 5 is played at frame 20 of the final video, and so on. To offset the scene and change scene playback rate: ■ Turn off Lock Range Bar To Scene Range. With Lock Range Bar to Scene Range off, both Scene Start and Scene End are enabled. As before, Scene Start specifies the first scene frame to play. Scene End specifies the last scene frame to play, and the length of the range bar determines playback speed. If the range bar specifies the same number of Video Post frames as there are corresponding scene frames, then playback is at the scene's playback rate. If the range bar specifies fewer frames, the scene is sped up. If the range bar specifies more frames, the scene is slowed down. When it executes, Video Post automatically skips frames or adds frames to control the speed of scene playback. For example, if Scene Start is frame 5 and Scene End is frame 35, the range bar represents 30 frames overall. If the range bar covers only 10 Video Post frames, scene playback is sped up to fit 30 frames into 10 of the final video. If on the other hand, the range bar covers 120 frames, scene playback is stretched to slow it down.
