In and out points can be set as markers within the timeline of a given video. The points can be used to define the start/end time video playback or used as markers for jumping and looping.
Setting In and Out Points
Set the in/out points with the timeline handles, by clicking the ‘set in/out point’ UI buttons, with the ‘i’ and ‘o’ keys, or from Control menu in the player.
From UI Buttons
Tip: In and out points are saved within the playlist file allowing you to preserve in and out marks for subsequent plays.
Jump to the in/out points with the ‘jump to in/out point’ UI buttons or with the shift+’i’ and shift+’o’ keys.
Un-set the in/out points with opt+’i’ and opt+’o’, or from the Control menu.
