64 Chapter 4 Working With 24p and Variable Frame Rate Video
Using A DVX100 NTSC Camcorder With Advanced Pulldown
The steps below explain the workflow for capturing and outputting 24p video using
the Panasonic DVX100 NTSC camera. Other NTSC camcorders that use this advanced
pulldown method can also follow this workflow.
Step 1: Shoot with advanced pulldown (23.98 at 29.97)
Choose the 24p advanced pulldown option on your camera. This creates 29.97 fps NTSC
video that contains 23.98 fps progressive frames using a 2:3:3:2 pulldown pattern.
Step 2: Remove 2:3:3:2 Advanced Pulldown From 24p Video During Capture
Choose or create a capture preset that has the “Remove Advanced Pulldown and/or
Duplicate During Capture From FireWire Sources” checkbox selected.
Duplicate video fields are discarded during capture, resulting in a 24p (23.98 fps) media
file on disk after capture.
If you have already captured your video at 29.97 fps, you can remove duplicate fields
from your media file after capture.
To remove 2:3:3:2 advanced pulldown from your media files after capture:
m Select the 29.97 fps clips in the Browser, then choose Tools > Remove Advanced Pulldown.
Your media files will remain the same size, but they will be set to play back at 23.98 fps.
If no advanced pulldown flags are detected, the media file remains at 29.97 fps.
Step 3: Edit at 23.98 fps
You can edit your footage in a 23.98 fps sequence. To preview your video on an
external NTSC monitor while you are editing, you can choose one of several pulldown
options to convert the 23.98 fps video to 29.97 fps. The 2:2:2:4 option is the least
processor-intensive, but it should only be used for previewing.
For more information about real-time pulldown options, see the Final Cut Pro 5
User Manual, Volume III, Chapter 23, “Using RT Extreme.”
Step 4: Output back to 29.97 fps NTSC video with advanced pulldown
After you finish editing your movie, you can output back to 29.97 fps NTSC video
by introducing a pulldown on the FireWire output. You can choose one of several
pulldown patterns, either from the Real-Time Effects (RT) pop-up menu in the Timeline
or in the Playback Control tab of System Settings. For output back to tape, you should
choose advanced pulldown (2:3:3:2), or normal telecine pulldown (2:3:2:3).
You can also export your movie to a 23.98 fps QuickTime movie or image sequence for
delivery to a video-to-film transfer lab.
