-\end{figure}
-A description of the fundamental/common terminology for choices follows.
-\begin{description}
- \item[All Edits (ripple)] shorten or lengthen the start or end of a single piece of media while moving all media to the right of that clip up or down on the timeline correspondingly. Timeline duration is modified. In a drag \textit{All Edits} operation, the beginning of the edit either cuts data from the edit if you move it forward or pastes new data from before the edit if you move it backward. The end of the edit pastes data into the edit if you move it forward or cuts data from the end of the edit if you move it backward. All the following edits shift. If you drag the end of the edit past the start of the edit, the edit is deleted.
- \item[One Edit (roll)] move the in and out point of a single clip without changing the timeline duration. In a drag \textit{One Edit} operation, nothing is cut or pasted. If you move the beginning or end of the edit forward, the source reference in the edit shifts forward. If you move the beginning or end of the edit backward, the source reference shifts backward. The edit remains in the same spot in the timeline but the source shifts.
- \item[Src Only (slip)] move the in and out point of a single clip without changing the timeline duration. In a drag \textit{Src Only} operation, nothing is cut or pasted. If you move the beginning or end of the edit forward, the source reference in the edit shifts forward. If you move the beginning or end of the edit backward, the source reference shifts backward. The edit remains in the same spot in the timeline but the source shifts.
- \item[Slide] a single clip is moved but retains its current in and out point; however the out point of the clip to the left changes and the in point of the clip to the right also changes. Timeline duration remains the same.
- \item[Edge Left / Right] moves the edge of the clips.
- \item[No effect] no changes are made. You might want to use this choice to prevent accidental movements.

-\paragraph{How to do a J-cut or L-cut} A J-cut is a split edit film editing technique in which the audio from a following scene overlaps the picture from the preceding scene, so that the audio portion of the later scene starts playing before its picture as a lead-in to the visual cut. An L-cut is a different split edit film editing technique in which the audio from preceding scene overlaps the picture from the following scene, so that the audio cuts after the picture, and continues playing over the beginning of the next scene (figure~\ref{fig:j-cut}). To do either a J-cut or an L-cut, you first shorten the first or second video a little. Then you block the audio tracks from changing by disarming the appropriate tracks. Finally use \textit{One Edit (roll)} the cutting edge off the videos. Moving to the right creates a J-cut and moving to the left creates an L-cut.
