You can replace one or more sources in the history of record clips. The sources you swap must be of the same resolution and bit depth. You can render the swapped sources directly in History View.

Replacing the sources in clip history allows you to:

• Consolidate sources before you archive your projects.
• Reuse setups for different clips.

If the new source is longer than the original source, the new source is shortened to fit the duration of the original source. If the new source is shorter that the original, the last frame of the new source is repeated to the end of the segment.

To replace sources in a clip’s history:

1. Display the history of a record clip. See Displaying Clip History.
2. Do one of the following.

   Do this:	To swap:
   Double-click a source	The original source with another.
   Press Ctrl and double-click a module node	All of the sources used in a module.

   The cursor becomes a coloured arrow to indicate what type of source you can select.

   Use:	To select:
   Red arrow	The front clip. Only this arrow appears if you selected a source clip and not a module node.
   Green arrow	The back clip.
   Blue arrow	The matte clip.

3. Click the source clips you want to swap in to the clip history.

   The sources are swapped and the Render button becomes active.
