96 Chapter 5 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 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 > 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.
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 two 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.
