- \item[Left Mouse Button (LMB) usage:] If you grab the edit handle from the right side, you will see a left arrow and dragging the boundary will modify the right edit playback starting time. If you grab the edit handle from the left side, you will see a right arrow and dragging the boundary will modify the left edit playback ending time. In both cases, the composer will show the edit endpoint of the changed edit.
- \item[Shift LMB usage:] The effect on the edits is the same as described above, but the composer will show a split screen of
- the left and right edits as they appear at the drag handle boundary. Dragging will only change one of the two images, since only one edit is being changed.
- \item[Middle Mouse Button (MMB) usage:] Both the left and the right edit ending/starting times are updated. The image shown in the compositor will be drawn from the side of the drag grab, that is the left if it is grabbed from the left, and the right if it is grabbed from the right.
- \item[Shift MMB usage:] The effect on the edits is the same as described above, but the composer will show a split screen of
- the left and right edits as they appear at the drag handle boundary. Dragging will change both of the two images, since both edits are being changed.
- \item[Right Mouse Button (RMB) usage:] The start/end point of the current edit is moved, but the edit length is unchanged only one image changes since only one edit endpoint is view is updated.
- \item[Shift RMB usage:] The effect on the edits is the same as described above, but the composer will show a split screen of
- the left and right edits as they appear at the drag handle boundary. Dragging will only change one of the two images, since only one edit is being changed.

-\subsection{Snapping while Cutting and Dragging}%
-\label{sub:snapping_cutting_dragging}
-
-\paragraph{Cutting/Snapping edits} cuts from an edit handle to the insert point.
-There are Edit Panel buttons which normally are used to move to the previous or next edit handle/label.
-\begin{wrapfigure}[5]{r}{0.2\linewidth}
- \vspace{-1ex}
- \centering
- \includegraphics[width=0.7\linewidth]{images/snap.png}
-\end{wrapfigure}
-They look like tags and the letter E on the menu bar and are oriented forward/backward. These same buttons can be used to \textit{cut} from the insert pointer to the previous or next edit/label when the \texttt{ctrl+alt} keys are both pressed when the buttons are used. They \textit{snap} off the media instead of doing the standard re-positioning. This is useful to minimize the number of operations necessary to cut between edits/labels.
-
-Instead of using the edit panel buttons, you can more easily use the following keyboard shortcuts to perform the same functions:
-\begin{center}
- \begin{tabular}{l l l}
- \toprule
- snap\_right\_edit & ctrl+alt+ '.' & \\
- snap\_left\_edit & ctrl+alt+ ',' & \\
- snap\_right\_label & ctrl+alt +shift '.' & shift+period is the > sign on US keyboards \\
- snap\_left\_label & ctrl+alt +shift',' & shift+comma is the < sign on US keyboards \\
- \bottomrule
- \end{tabular}
-\end{center}
-
-\paragraph{Drag Snapping} if you hold down the \texttt{Ctrl + Alt} keys while dragging using the mouse, once the clip gets near to an edit, a label, an in/out pointer or the start/end of the timeline, the dragged clip will snap next to that marker. The 2 will now be exactly aligned with no gap and no overlap. As you drag the clip close to one of the markers, when they are within a short distance they start to stick and stay that way until you move further away from that distance. Also, the line will turn color from green to yellow while in the sticky phase.

-\subsection{Nesting}%
-\label{sub:nesting}
-
-\paragraph{Nested Assets} A nested asset is an EDL session that embeds an existing EDL session, all tracks, all plugins, editing, and effects into a media object that appears as one audio/video media object, no plugins, editing, or effects. It is as if the existing EDL was rendered, and loaded in its place. This has several interesting side effects. First, you don’t have to render the entire media file to see any portion. Second, it requires no rendering compute time or storage. Third, it changes the precedence of the composer so that you get more control over the projection and automation, so that the results can be sent into another rendering step, not simply part of the current stack. It groups the plugin stack in much the same way that an arithmetic expression is grouped by parenthesis.
-
-The EDL session and the rendered output are visually equivalent. Nested assets allow for complex grouping and stacking of effects, and makes media access much more flexible. This feature can be used recursively, that is, any number of sessions may be stacked and referenced as an asset, as long as all of the rendering resources are available. Nested assets are added to the timeline by using the pulldown File $\rightarrow$ Load files\dots on the main menu and selecting the \textit{Insertion strategy} of \textit{Nest asset}. The file will be pasted into the timeline over the current selection or at the insertion point.
-
-It is somewhat important to note that nested assets and nested clips will have index files automatically created. These index files can start to clutter up your \texttt{\$HOME/.bcast5} directory with files named \texttt{Nested\_\#\#\#.idx} and you may want to periodically delete any index files which are no longer in use.
-
-\paragraph{Nested Clips} It is also possible to create \textit{clips} and convert them to \textit{nested edl}. This is done by first creating a clip using the standard cut, clipboard, paste, and/or edit panel buttons. Now, using the resources \textit{clip} folder, select a clip to be nested, and use the right mouse button to select a clip. This activates the clip popup menu. Select the \textit{Nest to media} menu item, and the clip will be converted to a \textit{Nested: Clip}. Conversely, you can select a \textit{Nested: Clip}, use the \textit{EDL to clip} menu item, and the clip will be reverted to a \textit{Clip}. This works similarly to the group / un-group editing features of many graphic design editing programs, but in this case the groups are rendered compositions (figure~\ref{fig:nesting}).
-
-Nested clips can be proxied and when they are, the resulting files
-are placed in the user's \$HOME/Videos directory by default. This can be modified by changing
-
-Settings $\rightarrow$ Preferences $\rightarrow$ Interface tab, Nested Proxy Path.

-\paragraph{Usage Examples of Nested Clips}
-
-\begin{description}
- \item[Example 1:] You want to make a flashback/rewind at the end of your video
-that represents a quick summary of the entire video in black and white. On
-he timeline, you have 60 seconds of edits with clips, cuts, zoom in, zoom
-out and any other edits. Now you want to get this 60 seconds "compressed"
-to 10 seconds, play in reverse, and in black and white at the end of your
- video.
- You would copy the 60 seconds in a clip, nest the clip in the Clip folder
-of the Resources window and drag it to the timeline. You will see only a
-clean clip without all of the edits that were used to create it because
-nesting display a clip without having to actually use the Render menu.
- Now you can add a Reverse effect, Color3way plugin for black and white, and
-use the Speed auto to get the 60 seconds down to only 10 seconds.
- \item[Example 2:] You are working on a complex project with a team in a separate
-location. You create some sub projects, i.e. sequences, that you or the
-team will use in the Master project to merge the sequences in the right
-order and to make the final color correction steps.
-\end{description}
-
-In each of the examples you can see the benefit of nesting to create clean
-looking timelines because of the automatic rendering capability of nesting.

-\subsection{Copy/Paste clips/medias across Multiple Instances}%
-\label{sub:copy_paste_multiple_instances}
-
-It is easy to copy/paste clips/media within a single instance of cinelerra or across multiple instances. The reason this works is because there are hidden X cut buffers and these are used to transmit EDL from 1 instance to another.
-
-\noindent Steps to copy from a source timeline and paste to a target timeline:
-
-\begin{enumerate}
- \item highlight a selection on the timeline in 1 instance of Cinelerra
- \item use the Copy icon (shortcut c) on the main menu bar to copy into a buffer
- \item move the pointer to another instance of Cinelerra and set an insertion point in its timeline
- \item use the Paste icon (shortcut v) to paste the clip to that other instance selection target
-\end{enumerate}
