4 Follow the steps in Using Batch Reverse Telecine for Multiple Source Clips to perform the batch reverse telecine. Note: If you connected the original reverse-telecined clips to the database records using the Reconnect command, the new reverse-telecined clips should automatically be connected to the database. Making Adjustments to Audio Speed If you need to make audio speed adjustments in order to reestablish 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. First, unlink the audio and video clips. Select the audio clip in the Timeline, then choose Modify > Speed and enter a new speed percentage. For example, to slow down an audio clip by 0.1 percent, enter "99.9." Relink the audio and video clips when you have finished modifying the speed of the audio clip. • Some sound recorders and audio playback equipment can have their playback speed 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. You use this equipment before capturing the audio into your computer. • 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 post-production facility that can adjust the speed. Synchronizing Separately Captured Audio and Video If 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, a feature called merged clips lets you link one or more source media files together so that they become one clip. First you synchronize them, and then you merge them into one clip.
