As the name implies, splitting a clip divides it into two adjacent clips, with new beginning/end points being created accordingly.
In PiTiVi, splitting is a “non-modal” operation; this means that you do not have to “activate” a particular tool before doing the split action. Splitting occurs where the playhead is currently located (see also Moving the playhead). Combined with zooming, frame-by-frame seeking with the keyboard or scrubbing, modeless splitting is not only fast and efficient, it is also very accurate.
Selections affect splitting in the following ways:
Only the selected clips under the playhead will be split.
If no clips are selected, all the clips under the playhead will be split.
To split a single clip:
Click on the clip.
Reposition the playhead (if needed).
Click on the Split button on the timeline toolbar or press S.
To split all the clips across the all layers:
Click on a blank area of the timeline (this will deselect all selected clips, if any).
Reposition the playhead (if needed).
Click on the Split button on the timeline toolbar or press S.
To split multiple selected clips:
Position the playhead where you want to split.
Add or remove clips to the selection with the Ctrl modifier key. This will not affect the playhead's position.
Click on the Split button on the timeline toolbar or press S.
