Nested Clips

It is also possible to create clips and convert them to 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 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 Nest to media menu item, and the clip will be converted to a Nested: Clip and put in Media folder. Conversely, you can select a Nested: Clip, use the EDL to clip menu item, and the clip will be reverted to a 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 6.7).

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 Preferences Interface tab, Nested Proxy Path.

creating nested clips is a complicated internal process for CINELERRA-GG, especially for managing audio tracks. Therefore you need to make sure you have your project set up as you expect before you start nesting with the Nest to Media command. Below are several things to remember.

Usage Examples of Nested Clips

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.
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.

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.
