If you have not keypunched your footage, you can determine pulldown according to clapsticks or

any other distinctive frame at the beginning of the clip. It is easier to determine the pulldown if

the frames depict motion.

For instructions on how to modify the pulldown phase, see “Modifying the Pulldown Phase After

Capturing” on page 275.

To determine the pulldown phase:

1. While you view the video transfer on a monitor, go to the keypunched (or clapsticks) sync

point for the beginning frame of the clip you logged.

2. Use the step wheel on the tape deck to step (jog) past the sync point frame field-by-field.

You will see either two or three keypunched fields. If the footage is not keypunched, look for

two or three fields with little or no motion.

3. If there are two fields, the pulldown is either A or C. Step through the fields again, and note

where the timecode changes:

- If the timecode does not change from the first to the second field, the fields came from

an A frame.

- If the timecode changes from the first to the second field, the fields came from a C

frame.

The illustration shows a keypunch on the A frame. Notice where the timecode changes.

Determining pulldown for keypunched footage. Red lines indicate the location of timecode changes.

4. If there are three keypunched fields, or fields without motion, the pulldown is either B or D.

Step through the fields again and note where the timecode changes:

- If the timecode changes from the second to the third field, the fields came from a B

frame.
