Modifying the Pulldown Phase After Capturing
276
To determine the correct pullin frame, use one of the following approaches:
t If the source footage includes burn-in code with the pulldown phase, go to the start of the
clip and look for the pulldown for the first frame.
t If you want to maintain the start timecode for each clip, review the original tape field by
field, using the procedure described in “Entering Pulldown Information” on page 151.
t If you do not need to maintain the start timecode:
a. Step through the clip frame by frame (using the Step buttons or another method). Look
for two frames that are identical (no movement).
b. Think of these frames as frames B and X of a four-frame series.
Incorrect sequence (top, no movement between B and X frames) and correct sequence (bottom)
Step backward (either one frame from the B frame or two frames from the X frame) to
locate the correct A frame. Note the last digit of its timecode. Timecode for all A frames
in the clip starts either with this digit or this digit plus 5. For example, if the A frame has
the timecode 1:00:10:20, timecode for all A frames in the clip ends in either 0 or 5.
c. Compare these digits with the last digit of the start timecode (first frame) of the clip to
determine the correct pullin.
For example, if the A frame ends in 0 or 5, and the start timecode ends in 4, the pullin is
D.
d. If the pullin for the clip is the X frame, you need to modify the timecode to produce a
number you can associate with a pullin.
For example, if the A frame ends in 0 or 5, and the start timecode ends in 2, the pullin
falls on the X frame and you need to modify the timecode along with the pullin. Move
forward one frame to create a start timecode ending in 3. Then you can change the pullin
to C.

When you change the timecode of a clip, you lose the key number of the clip. You need to
enter it in the bin and adjust it to match any changes to the timecode.
