Transport controls and playback settings are located directly below the Playlist and Scrub-Bar.

Figure 126

Time Display

During playback, the uppermost timecode field beside the transport controls displays the current countdown time for active playlist item or for the entire playlist when the Playlist mode button is enabled.  (As mentioned earlier, the time show below is the embedded clip timecode.)  Left-click the field to type in a timecode, then press Enter to jump to that point in the file (or playlist).

Hint: The time display and scrub bar color provides visual indication that the playback is nearing its end.  Ten seconds before the end of play for the current item, the digits in the time display and the scrub bar background turn amber.   With only five seconds left, the color changes to red.

Playlist Mode

Normally, Media Player playback stops when the Out Point of the current playlist item is reached (unless Loop is also enabled, in which case playback of the current item repeats until manually interrupted). 

Clicking the Playlist mode button (Figure 127) tells the Media Player to operating in continuous play mode, advancing through the playlist items until the last one has played.

Transport Controls

A simple set of controls beneath the playlist pane provides all playback-related functions:

  • *Previous button – go to previous playlist entry
  • Stop (clicking Stop when already stopped goes to the first frame)
  • Play
  • *Next buttongo to next playlist entry
  • (Not shown) – Double-click an entry in the playlist pane to begin playback at the start of that playlist entry
Previous, Next and Presentations

Figure 128

It’s extremely useful to realize that, since TriCaster Advanced Edition supports transitions between playlist items, pressing Previous or Next likewise employs transitions.  Whether playback is underway or stopped, and whether the items are clips or stills, you can use Previous and Next to transition backward and forward between items.

This provides a perfect way to manage presentations using Media Players, hence our inclination to refer to this as the “Presentation workflow’.  With macros (and perhaps MIDI buttons) driving the presentation, this makes it easy to handle control graphics and video for seminars, to update weather graphics, and more.

Hint: In addition, since transitions support transparency, you can queue up a series of titles in a playlist, display it in a DSK, and transition backward and forward between titles interactively simply using Previous and Next.


The Speed control is only found in DDRs (as opposed to GFX or SOUND players).  The DDR supports variable speed playback between 25% and 400% of the normal rate (100%).  Speed can even be adjusted during playback.

Figure 129

Note: Certain highly compressed video file formats cannot successfully be played back at rates beyond 200%, even though Speed value is set to a higher value.

As is common for numeric input controls in TriCaster, drag left or right to adjust the Speed value, or click the slider to access a direct entry field allowing you to type a value using the keyboard.


Hint: Press Shift while double-clicking Speed to quickly reset to the 100% default.


Enabling Loop repeats playback continuously (respecting the Single switch state).

When enabled, the Autoplay switch has several important effects.  First, it initiates playback automatically when the associated Media Player is placed on Program Out by a (Switcher) Take or Transition operation either directly (as a Switcher row selection) or indirectly – such as by being displayed via an M/E channel or DSK operation.

Second, if player output is displayed on Program the reverse Switcher transition occurs automatically as the end of play approaches, whether the Out Point of the current item for Single play or the end of the playlist.  (This behavior is optional for M/Es – see Options in Section 14.2 and Section 7.1.)

Note: Unlike Switcher transitions, the DSK ‘out’ effect does not occur automatically as the end of play approaches.

In either case, when the Media Player is in Single mode, the current play position advances to the next item after playback is automatically stopped.
