A Caution About Using OffineRT Media with Cinema Tools, Avoiding Dropped Frames, In Final Cut Pro

Page 106 highlights

• How to prepare for batch capturing (if you have a video deck with device control) • Considerations for capturing source clips individually (if you do not have device control) A Caution About Using OffineRT Media with Cinema Tools When you capture media with the OfflineRT Easy Setup in Final Cut Pro, your captured media is highly compressed, allowing you to capture more source clips to your hard disk-approximately 2 hours of video per gigabyte (GB) of hard disk space. However, it can be very difficult, if not impossible, to read the key number and timecode information in the window burn after capturing with OfflineRT compression. You typically need to see the window burn in order to verify and correct the key number and timecode values and to use the Cinema Tools Reverse Telecine feature. For this reason, OfflineRT may not be ideal for Cinema Tools users. For more information about OfflineRT, see the Final Cut Pro documentation. Avoiding Dropped Frames If computer performance is impeded or if your scratch disk is not fast enough, frames may be dropped during the capture process, meaning one or more individual frames are not captured at all. When a frame is dropped during capture, the frame before it is repeated. As a result, a frame you see while editing may not be the frame you see when the film is cut. Dropped frames can cause timecode errors, which can result in an incorrect cut list and interfere with the reverse telecine process. You can prevent this problem in Final Cut Pro by setting the program to stop capturing and to notify you when a frame is dropped. To set Final Cut Pro to stop capturing when frames are dropped 1 In Final Cut Pro, choose Final Cut Pro > User Preferences. 2 In the General tab, make sure "Abort capture on dropped frames" is selected. When this option is selected, a message appears when frames are dropped during capture and the capture is stopped. If dropped frames occur, first make sure that other programs are not open, so that performance is not slowed. Then, recapture the source clip. If you attempt to use the Reverse Telecine feature for a source clip that contains dropped frames, a warning appears. 106 Chapter 7 Capturing Source Clips and Connecting Them to the Database

Avoiding Dropped Frames
If computer performance is impeded or if your scratch disk is not fast enough, frames
may be dropped during the capture process, meaning one or more individual frames are
not captured at all. When a frame is dropped during capture, the frame before it is
repeated. As a result, a frame you see while editing may not be the frame you see when
