There are a few controls you want to know about in order to playback and edit your videos. The play bar provides controls for stopping, starting, and adjusting different aspects of your playback experience.
1. "Play/Pause" – your videos will play by default when loaded into the player view. Press pause to stop play back, and play to resume play back.
2. "Volume" – toggle whether to play/mute audio during play back.
3. "Duration" – The time displayed beside play/pause is your current progress into the video clip playing. The time displayed at the end of the play bar is the total duration of the clip being played.
