Verifying and Correcting Edge Code and Timecode Numbers

Assuming you know the timecode, key number, or ink number values for a frame in a clip—either by a marked frame or by window burn—you can use the Identify feature to verify these values for the clip. Verification is important because your cut list or change list is only as accurate as these values.

Verifying values with the Identify feature is especially useful when:

Important: The Identify feature can track edge code numbers only if the edge code number-to-timecode relationship is continuous, as it is with most camera-roll transfers. See Is Your Edge Code Number-to-Timecode Relationship Continuous or Noncontinuous? for more information. If the edge code number-to-timecode relationship is noncontinuous, you can verify and correct the edge code number and timecode values for the source clips by visually checking these values against the window burn and, if necessary, manually updating the edge code number and timecode values in Cinema Tools and the timecode values in Final Cut Pro.

To verify and correct the edge code and timecode values entered for a clip
  1. If it isn’t already open, open the clip in the Clip window in one of the following ways:

    • Choose File > Open Clip (or press Command-O) and use the dialog to select the clip.

    • Click Open Clip in the Detail View window of the clip’s database record.

  2. In the clip playback area, locate a frame near the beginning of the clip for which you know the correct edge code number or timecode value. This is easy if your video has window burn.

  3. If necessary, click Identify to show the record’s settings.

  4. Look at the Key, Ink, and Video Timecode fields in the Identify pane to see if the numbers match the window burn of the frame in the Clip window. (You may be using ink numbers instead of key numbers, or vice versa. If so, you can leave the field you aren’t using blank.)

  5. If any of the Key, Ink, or Video Timecode fields are incorrect, enter the correct numbers in the fields.

  6. In the clip playback area, locate a frame near the end of the clip and repeat steps 4 and 5.

    • If the edge code number and timecode values are correct at the beginning of the clip, but not at the end of the clip: Frames may have been dropped during capture, in which case you should recapture the clip. See Avoiding Dropped Frames for more information. It might also be because the clip doesn’t have a continuous edge code number-to-timecode relationship, in which case the Identify feature cannot help you confirm the edge code number and timecode values because it works by a calculation based on a continuous edge code number-to-timecode relationship.
    • If the timecode value is incorrect: There is a good chance that the timecode is wrong in Final Cut Pro. Open the same frame in Final Cut Pro and see if the timecode value is correct. If it isn’t, make sure to correct the timecode in Final Cut Pro. You can do this by using the Modify Timecode dialog. See the Final Cut Pro documentation for more information about how to modify the timecode.

      If you used serial device control, the timecode mismatch may have happened because you didn’t set the appropriate timecode offset in Final Cut Pro for the specific deck you used. You need to make this setting once per deck, per computer. For more information, see the section about calibrating the timecode signal in the Final Cut Pro documentation.

  7. If you entered new numbers in the fields, click Save. Otherwise, if the values were already correct, close the window.
