When creating clips with clip history, you can keep track of the sources used as well as the intermediates used to build the final clips.

Sources are any of the original clips that you use to build an effect, for example, clips that you captured using an EDL. Intermediates are clips that are created when building a clip that uses multiple effects or operations. For instance, you may need to resize or colour correct a clip before bringing it into the Keyer. The clip you process from the Keyer is the final clip, but the clip processed from the Resize module is an intermediate.

There are a number of tools you can use to keep track of the sources and intermediates used. Use the Search tool to find clips with history or clips that were used to create a clip with history. Use the Delete tool to delete sources or intermediates for a selected clip with clip history. Use the Commit tool to commit a clip with history just as you would any other clip.
