If any problems were encountered, such as running out of disk space or memory, an error message describing the problem also appears in the log. 122 Chapter 6 Preparing the Source Clips for Editing Making Adjustments to Audio Speed If you need to make audio speed adjustments in order to re-establish synchronization with the video, there are various ways you can do this. Note: The reverse telecine and conform processes automatically adjust the audio speed in a clip to match changes made to the video frame rate of the same clip.  You can adjust the speed with the Final Cut Pro Speed command. Select the audio clip in the Timeline, then choose Modify > Speed and enter a new speed percentage. Relink the audio and video clips when you are finished modifying the speed of the audio clips.  Some audio recorders and playback equipment can have the speed of their playback adjusted to sync with the video. When using such equipment, you can capture the audio with the correct speed for synchronization.  You can use specialized equipment, such as that available from Aaton, designed to control and adjust the audio for proper sync with any video rate.  If you don't need the audio speed adjusted for editing, but you do need it adjusted for the finished project, you can have the audio finished at an audio postproduction facility that can adjust the speed. Synchronizing Separately Captured Audio and Video If you your sound and picture were not synchronized onto videotape, but were instead captured separately, you can synchronize them in Final Cut Pro. In Final Cut Pro 4, a new feature called merged clips lets you link one or more source media files together so that they become one clip. The clapper boards (also called slates) in your shots provide the audible and visible cues on which to sync your audio and video clips. There are a couple of different techniques you can use to synchronize clips before merging them, depending on how you shot your footage. Chapter 6 Preparing the Source Clips for Editing 123  If the timecode of your video and audio clips isn't identical, and you slated all your shots at the beginning with a clapper board, you can use In points to line up all the clips you want to merge. When you do this, the beginning of the resulting merged clip corresponds to the In point you used, and all the clips line up at that point. The end of this merged clip corresponds to the end of the clip with the latest timecode value. Video Audio Audio Merged clip  If the timecode of your video and audio clips isn't identical, and you have one or more shots that you tail-slated at the end, you can use Out points to line up all the clips you want to merge. When you do this, the end of the resulting merged clip corresponds to the Out point you used, and all clips line up at that point. The beginning of this merged clip corresponds to the beginning of the clip with the earliest timecode value.

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 important things you need to do after you break down source clips: 1 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. 2 Update the clip's database record so that the edge code number information is correct for the clip's new first frame. (This is only necessary if you delete material from the beginning of a clip. ) Note: See "Is Your Edge Code Number-to-Timecode Relationship Continuous or Noncontinuous?" on page 64 for more information. There are 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. [. . . ] In traditional filmmaking, the workprint is edited first, and then used by the negative cutter as a guide for cutting the original camera negative. In digital filmmaking, a workprint is usually used to verify the cut list and to create a prototype of the film to view on a big screen before conforming the negative. Sometimes called a work pix or cut pix. 228 Glossary 16mm film 18, 202, 203 2:2:2:4 pull-down 195 2:3:2:3 pull-down See also 3:2 pull-down described 187 removing with Cinema Tools 190 2:3:3:2 pull-down 25 advantages 189 described 188 removing with Cinema Tools 190 removing with Final Cut Pro 189 2:3 pull-down.
