different functions; on the left, it’s the Source track indicators, while on the right, it’s the
sequence track selection.
Note
Remember, Timeline track selection buttons matter when rendering effects or making
timeline selections, but they don’t affect editing clips into a sequence; only the source
track indicators do.If you drag a clip into a sequence, the position of the source track indicators is ignored, though
only content on enabled source tracks is added.
Using In and Out points in the Timeline panel
The In and Out points used in the Source Monitor define the part of a clip you will add to a
sequence.
The In and Out points you use in a sequence have two primary purposes.
To tell Premiere Pro where a new clip should be positioned when it is added to a sequence.
To select parts of a sequence you want to remove. You can make precise selections to
remove whole clips, or parts of clips, from specific tracks by using In and Out points in
combination with the track selection buttons.Selected parts of a sequence, defined by In and Out points, are highlighted in the Timeline
panel. The highlighting doesn’t extend to tracks that aren’t selected.Setting In and Out points
Adding In and Out points in the Timeline panel is almost the same as adding them in the
Source Monitor.
One key difference is that unlike the controls in the Source Monitor, the selection buttons on the
Program Monitor also apply to the Timeline.
To add an In point to the Timeline at the current position of the playhead, make sure the
Timeline panel or Program Monitor is active and then press the I key or click the Mark In button
on the Program Monitor.
