Accessing the Playback Panel
The Playback panel is available when you are editing a shot and you have selected one of the following shot elements: Foreground, Background, Audio, or Channel A,B,C.
In the example shown below, we are editing the "Movie" shot and have selected the Channel A shot element.
Movies and Music
This panel allows you to control how movies and music play in Wirecast.
You can control, for example, where in the movie or music Wirecast should begin and end, whether the movie should loop, when it is done playing, etc.
Here is more information on the different parts of the Playback Panel:
Live Playback -- controls whether your changes affect the Live Broadcast
Playing / Scrubbing -- controlling the start and stop
In / Out Points -- controls where in the media to start and stop playing
When Finished -- what to do when the media is finished (loop/hold/remove)
Begin Playing -- does the media automatically starts playing when it becomes live
Remember Position -- does the media remember its position when it is not live
Audio Controls -- Volume, Mute, etc
Media which has Playback
The playback panel will only allow modification of parameters on media for which the options are possible.
For example, if your media has no audio, then the audio controls will not be active.
A more common example is if your media is not temporal (has no time). For example, if you have a still image, you won't be able to set the In point or Output or "play" the image.
Scope
The Playback panel information is stored in the Shot itself.
This means that when you, say, set the In Point you are only setting the in point in the shot you are editing.
If that media exists in a different shot, or even exists in the same shot but in a different shot element your changes will not be applied there.
