Modifying Clips with Clip History

To create clip history while rendering:

1. In the Preferences menu, click the General tab.
2. Under Default Rendering Options, select Render & Create History in the Render box.
   NoteIn Batch and Tools editors, you also have this option in the Render box, but by setting it in the Preferences menu, you can make sure that history is enabled for all renders (including tools that render a result directly in the workspace without entering the editor).

To view clip history in the timeline:

1. Select a source or sequence clip with history.
2. From the Timeline View Mode box, select History.

   The view changes to a history view of the selected clip. Batch FX and Timeline FX applied to a clip are included in its history. From the history view you can see and edit all of the effects or tools applied to a clip. Double-click effects to re-enter the editor, or use the right-click context menu for other editing options.

   
   TipTo quickly enter the history view, double-click the "H" icon on a clip on the desktop. To bypass history view, and quickly re-enter the last tool used on a desktop clip with history, press Shift and double-click the “H” icon on the clip.

To modify clip history through History View:

1. Display the clip history of a clip.
2. Double-click a node (in schematic view) or an entry (in list view) to open the corresponding tool or Timeline FX editor.
3. Edit the settings as needed.
4. If you loaded the clip into a tool editor, do one of the following:
   • To save your changes, select Return from the Exit Options box.
   • To exit without saving your changes, select Cancel from the Exit Options box, and then confirm.
5. If you loaded the clip into a Timeline FX editor, click Exit.

To display History View in a Timeline FX editor:

1. Load a clip with clip history into a Timeline FX editor.
2. Click History.

   The clip history appears with the Timeline FX selected. You can display the history in Schematic or List View.

To replace sources in a clip’s history:

1. Display the history of a clip.
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 tool node	All of the sources used in a tool.

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

3. Click the source clips you want to swap in to the clip history. The sources you swap must be of the same resolution and bit depth.
   NoteIf 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.

   The sources are swapped and the Render button becomes active.

4. Click Render to render the swapped sources.

To explode clip history in Batch or Batch FX:

1. Double-click a clip with history in the Batch or Batch FX schematic to view its clip settings.
2. In the History section, select Explode History to expand the entire clip history into the process tree, or Explode One to expand only the most recent step of the clip's history.
   

   If the input clip to the last node also contains history, you can also expand the history for that clip.

   NoteThese history options are not available for Batch or Batch FX clips with non-supported effects (the clip appears with a lowercase "h" next to its name in the schematic). In this case, if you double-click the clip again, you are returned to the timeline view. You can switch to History view to see its clip history.
