Apple Final Cut Pro 7 - Manual (Page 1943)

Note: Even though the 2:3:2:3 pull-down pattern of a film-to-tape transfer is emulated
by this process, there are many other factors that contribute to a “film look,” such as
exposure, resolution, color, depth of field, and so on.
Most camcorders use a pull-down method referred to as advanced pull-down, which has
a 2:3:3:2 pattern instead of the traditional telecine 2:3:2:3 pull-down pattern. The advantage
of this pattern is that it is more efficient for digital devices or applications (such as
Final Cut Pro) to remove and introduce than the traditional 2:3:2:3 pull-down pattern.
In Final Cut Pro, you can remove the redundant fields during or after capture. Once the
redundant fields or frames are removed, you can edit at 23.98 fps. When you have finished
editing, you can output back to 29.97 fps NTSC video by reintroducing advanced pull-down
(2:3:3:2) or traditional 2:3:2:3 pull-down. If you are outputting to film or progressive-scan
video, you don’t need to add pull-down.
Note: 1080i60 footage also uses the same 2:3:2:3 and 2:3:3:2 pull-down patterns to record
24p footage.
Using an AG-DVX100 NTSC Camcorder with Advanced
Pull-Down
The workflow for capturing and outputting 24p video using the Panasonic AG-DVX100
NTSC camera is outlined below. Other NTSC camcorders that use this advanced pull-down
method can also follow this workflow.
• Stage 1: Shooting with Advanced Pull-Down
• Stage 2: Removing Advanced Pull-Down from 24p Video During Capture
• Stage 3: Editing at 23.98 fps
• Stage 4: Outputting to 29.97 fps Video with Advanced Pull-Down
Stage 1: Shooting with Advanced Pull-Down
To shoot with advanced pull-down (23.98 fps at 29.97 fps), choose the 24p advanced
pull-down option on your camera. This creates 29.97 fps NTSC video that contains 23.98 fps
progressive frames using a 2:3:3:2 pull-down pattern.
Stage 2: Removing Advanced Pull-Down 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. This checkbox is
available when you edit a capture preset in the Capture Preset Editor window (accessible
from the Capture Presets tab of the Audio/Video Settings window).
Duplicate video fields are discarded during capture, resulting in a 24p (23.98 fps) media
file on disk after capture.
