Mark the film reference frame number as the Edit In point and set 1:00:00:00 as the Edit In point

for the HD VTR.

While the film is parked on the reference frame enter 01:00:00:00 into the 9025TR's VTR time

code register using the Set Codes screen (accessible from the Edit menu or by pressing the F2

key). Make sure that the 9025TR is still set to the KeyKode Accuracy test mode. The VTR

Time code generator should be set to Internal Regen mode.

Perform an open-ended edit using the previously entered In points. Make sure you record the

Character windows of the 9025TR.

Turn on the 9025TR Status screen in Tracker. While the edit is in progress, look at the "Video

Timecode pulldown value on the 9025TR Status Screen in Tracker. If it shows "A", then the

Film *Sync Trim in the TLC is correct. If it is not "A", then adjust the Film *Sync Trim in the TLC

by the number of frames shown in the chart below.

NOTE: The Timecode Pulldown value is only valid while the edit is being performed.

Repeat steps 5 and 6 until the Timecode pulldown value is A.

3.6.3. Calibrating the HD VTR Timing

Once you have an edit where the Timecode pulldown value is "A", then go back to the first

frame of the edit. Compare the character burn-in of the 9025TR video time code with the TLC's

display of the VTR's time code. If they are the same then proceed to step 8.

If they are different, adjust the HD VTR *Sync Trim value in the TLC by the number of frames of

difference between the burn-in and the VTR's timecode. Perform the edit again. In order to be

able to distinguish the new edit from the previous edit it is recommended that you change the

colour correction significantly before performing the edit. Doing this each time you perform an

edit will minimise confusion in determining accuracy at the edit point.

Once you have an edit where the 9025TR Video Time Code burn-in agrees with the TLC's

reporting of the VTR timecode, then park the tape on the first field of the edit. Compare the time

code reported by the TLC with the Edit In point you selected for the VTR. Adjust the HD VTR

*In Trim value in the TLC until the edit occurs where you wanted it to be. Once you have set the

value, you will have to set the HD VTR *Out Trim to the same value.
