Dividing or Deleting Sections of Source Clips Before Editing Before you edit your media in Final Cut Pro, you have the option of further dividing or eliminating parts of source clips. If you used a batch capture list and device control for capturing, you may have captured your source clip files exactly as you want them. On the other hand, you may feel that the captured source clips need to be broken down into individual takes, or you may want to eliminate some of the content you captured before you begin editing in order to make efficient use of available disk space. Strategies for Breaking Down Source Clips Before Editing Before you begin, if the edge code number-to-timecode relationship is not continuous throughout the camera roll from which a source clip came, be aware that there are a couple of important things you need to do after you break down source clips: • Create a new database record for the new source clip that is created when you break down a clip, and make sure the new source clip is connected to the database record. • Update the clip's database record so that the edge code number information is correct for the clip's new first frame. (This is necessary only if you delete material from the beginning of a clip.) Note: See Is Your Edge Code Number-to-Timecode Relationship Continuous or Noncontinuous? for more information. There are a variety of ways to break down source clips before editing: • An easy way to break source clip files into smaller source clips is to use Final Cut Pro. First, make one or more subclips from the clip in the Browser. You can then use the Media Manager to delete any part of the clip that you did not select as a subclip. See the section about creating and working with subclips in the Final Cut Pro documentation for more information. • Another way to select and save portions of a clip is to use QuickTime Pro. If you use QuickTime Pro for this purpose, make sure to choose "Make movie self-contained" in the "Save as" dialog. See The Difference Between Self-Contained and Reference Media Files for more information. • If you are using hole-punched or otherwise marked frames (rather than window burn) to identify the key numbers for each of your source clips, make sure you do not trim off any of the marked frames. • If the telecine transfer involved the 3:2 pull-down method, it's a good idea to start each source clip on an A frame. After the 3:2 pull-down, A frames are the only film frames that are not divided into two video frames. Because of this and because the A frame is the start of the video five-frame pattern, it is preferable to have one as the first frame in all video clips. See About A Frames for more information.
