# Changing Keycode

You can change or add keycode to a sequence. You might do this, for example, if the keycode data was corrupted when written by the telecine, or if you entered wrong keycode values when using a third-party application to write keycode to an exported sequence.

NoteYou cannot apply keycode to audio files.

To change the keycode of a clip:

1. Access the Change Keycode tool in one of the following ways:
   - From the A/V Tools box, select Timecode, and then click Change KC.
   - In the Clip Library, click Tools, and then from the Tools box, select Change TC/KC, and click Keycode.
2. In the Keycode field, enter the keycode value that you want to apply to the frames of a clip.

   Ensure that you enter a keycode value according to the proper syntax. See Keycode Syntax.

3. Optional: To load the keycode of another clip, click the Get button next to the Keycode field, and select the clip.

   The keycode value of the current frame of the selected clip is loaded into the Keycode field. You can then edit this value with the keycode calculator, or apply this keycode to other clips by selecting them.

4. Do one of the following:
   - Click a clip to which you want to apply the keycode value.

     The value is incremented for each frame of the clip according to the values you set.

   - If you are using the Change TC/KC tool, select the clip to which you want to apply keycode, and then click Change.
