Modifying the Pulldown Phase After Capturing

250

To check for an incorrect pullin frame:

1. Look for a section of the clip that includes a series of frames with motion.

2. Step through the clip frame by frame (using the Step buttons or another method) and look for

two frames that have no movement.

If the pattern is two frames of movement followed by two frames of no movement, the pullin

is incorrect.

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.

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. 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.
