Viewing a Track

The track preview feature allows you to select a video, audio, and subtitle stream to view. You control which streams play using the buttons at the far-left side of the stream.

To preview a track
Do one of the following:
  • Control-click in the video stream, then choose Play from the shortcut menu.

  • Press the Space bar.

  • Move the playhead.

The Viewer tab moves to the front (if not already there) and shows the selected video stream and subtitle. You can also hear the audio of the selected audio stream through your system’s speakers or through an external audio decoder and monitor.

You can also see the video if you drag the playhead along the timeline in the Track Editor. If you click in the timeline, the playhead jumps to that position and its video appears in the Viewer tab.

About the Viewer Tab

You use the Viewer tab to preview tracks. It is also used as the Subtitle Editor when you create subtitles in DVD Studio Pro.

When previewing a track, you can use four buttons to control the preview:

  • Play/Pause

  • Stop

  • Step Forward

  • Step Reverse

Note: The Subtitle Editor tools in the Viewer tab are unavailable unless you select a subtitle to edit. See Creating Subtitles with DVD Studio Pro for more information.

Pausing or Stopping Playback?

The difference between pausing and stopping playback is what happens to the playhead:

  • When you pause playback by clicking the Play/Pause button: The playhead remains at its current position.
  • When you stop playback by clicking the Stop button: The playhead jumps to the position it was at when playback started.

You can also use your keyboard’s Space bar to pause or stop the track. The “Space bar toggles between play/pause” setting in the Track pane of DVD Studio Pro Preferences controls whether the Space bar pauses or stops the track:

  • With the checkbox selected: The Space bar pauses playback, leaving the playhead at its current position.
  • With the checkbox not selected: The Space bar stops playback, returning the playhead to its original position.

Holding down the Space bar while playing the clip allows you to stop playing the clip automatically by releasing the Space bar. The playhead then follows the above preferences setting.

Modifying the Step Buttons

The Step Forward and Step Reverse buttons move the playhead one frame at a time. You can use modifier keys to enhance their capabilities.

  • Holding down the Shift key while clicking the step buttons: This moves the playhead one second at a time.
  • Holding down the Option key while clicking the step buttons: This moves the playhead one Group of Pictures (GOP) at a time.
  • Holding down the Control key while clicking the step buttons: This moves the playhead one marker at a time.

You can also click a step button and continue to hold down the mouse button to repeatedly step the playhead.

Previewing Angles

If you are previewing a mixed-angle track and select a video stream other than V1, the preview still plays the V1 stream whenever the selected video stream is not present.

To see the multi-angle or mixed-angle stream actually function, you need to use the DVD Studio Pro Simulator.

Simulating a Track

Simulating a track allows you to verify all streams and any special interactivity you may have built into it.

To simulate a track
Do one of the following:
  • Select the track, then choose File > Simulate Track, or press Command-Option-0 (zero).

  • Control-click the track’s name in the Outline tab or its tile in the Graphical tab, then choose Simulate Track from the shortcut menu.

  • Control-click one of the streams in the Track Editor, then choose Simulate from Track from the shortcut menu.

These methods force the Simulator to start at this specific track instead of the First Play connection, as it does when you open it using the icon in the toolbar.

Once the track starts playing, you can use the Simulator’s controls to choose the streams to view (angle, audio, and subtitle).

See Simulating Your Project for information on using the Simulator.
