2. Open the Set Codes window in KeyLog TRACKER™ by selecting Set Codes... from the

Edit menu, or press the F2 key.

KeyKode footage number to 0000+00 by entering the values into the respective fields. (This

will allow you to tell when the KeyKode numbers have been automatically updated from the

incoming KeyKode information.) Press the OK button. Open the Encoder Status window by

pressing the

3. Back up the telecine to allow at least 5 seconds pre-roll time. Transfer a short section of film

(which includes the reference frame) to videotape. When the telecine achieves locked

PLAY speed, the telecine FRAME and LOCK LEDs on the KeyLog TRACKER™ status bar

should be on and there should be a '+' between the footage and frames in the character

generator. The KeyKode number on the KeyLog TRACKER™ time bar should update so

they are the same as the KeyKode of the reference frame.

KeyLog TRACKER™ status bar should be on. Press the HELP button in the Encoder

Status window if the FRAME, LOCK or KK indicators are not on.

4. Play back the videotape in slow shuttle or jog mode, and verify that the Video timecode and

KeyKode numbers and the pulldown letter (in 60i 24 Frames per second transfers) for the

reference frame are correct.

5. If the KeyKode numbers are not correct, recheck the head offset learning procedure as

described in section 3.4

6. If the timecode numbers are not correct, check that you have set the correct Film Rate

setting in the System Configuration that you created for this test.

7. In 24 FPS 60i transfers, the pulldown of the reference frame is not guaranteed unless you

are using a device such as a Time Logic Controller or POGLE to control the telecine. This

means that the reference film frame may correspond to more than one video frame, and that

the exact timecode / edge code numbering relationship is ambiguous except for A frame

pulldowns.

8. In 30 FPS 60i or 25 FPS 50i transfers the film frame and timecode numbers should change

when the picture content changes.

9. After you have made any adjustments, park the telecine with the reference frame in the gate

and repeat steps 2 through 4 until you have satisfactory results. If you are still experiencing

problems, recheck the accuracy of the numbers without KeyKode as described in section

3.3.

To verify the accuracy for other film formats or transfer rates, Select System

Configurations... from the Edit menu and double click on the Engineering Test System

Configuration. Select the appropriate Film type or Film transfer rate on the Film tab and

press Ok. Then repeat the verification procedure outlined above.
