Apple Cinema Tools 4 - Manual (Page 96)

If you know the edge code or timecode number for another frame in a clip, the Identify
feature can help you determine the correct timecode or edge code number for the first
frame of a clip. See
Using the Identify Feature to Calculate Database Information for
details.

Until you save, data in the Detail View window is not entered in the database. You can
choose Database > Revert Record (or press Command-R) to revert to the last saved version
of the record.
Using the Identify Feature to Calculate Database Information
You can use the Clip window’s Identify feature to determine the key number, ink number,
or timecode values for clips in the database. The database requires these values for the
first frame of the clip, but you might not have them if you aren’t creating database records
from a telecine log or if your clips lack window burn.
Note the following requirements for using the Identify feature to determine or verify edge
code or timecode values:
• You need to know a key number, ink number, or timecode value for at least one frame
in the clip.
• The clip needs to have a database record.
• The key number-to-timecode relationship must be continuous. See Is Your Edge Code
Number-to-Timecode Relationship Continuous or Noncontinuous? for more information.
Keep in mind that with the Identify feature, the Key, Ink, Video Timecode, and Sound
Timecode fields should always reflect the values of the frame currently displayed in the Clip
window, whereas in the Detail View window these fields are associated with the first frame
of the clip. The Identify feature will, however, calculate and enter the first-frame values
you see in the Detail View window.
Calculating Edge Code and Timecode Numbers
If you know the edge code (key number or ink number) and timecode values for any
frame in a clip, you can use the Identify feature to determine these values for the first
frame of the clip, and that information is automatically entered in the database.
This feature is especially useful if you are working with video that does not have window
burn, because without window burn you have to track the timecode and edge code by
physically marking one frame in each clip. If the frame that is marked is not the very first
frame of the clip, the Identify feature can calculate what the values are for the first frame,
and those values are automatically entered in the database.
