The
phase
of 3:2 pulldown refers to the point at which the two split-field frames fall within the first five frames of the
footage. Phase occurs as a result of two conversions that happen during 3:2 pulldown: 24-fps film is redistributed
through 30-fps video, so each of four frames of 24-fps film is spread out over five frames of 30 (29.97)-fps video. First,
the film is slowed down 0.1% to match the speed difference between 29.97 fps and 30 fps. Next, each film frame is
repeated in a special pattern and mated to fields of video.
When you apply 3:2 pulldown to footage, one frame of the film (A) is separated into two or three interlaced video fields (B) which are grouped
into video frames containing two fields each.
It’s important to remove 3:2 pulldown from video footage that was originally film, so that effects you add synchronize
perfectly with the original frame rate of film. Removing 3:2 pulldown reduces the frame rate by 1/5: from 30 to 24 fps
or from 29.97 to 23.976 fps. Reducing the frame rate also reduces the number of frames you have to change.
Premiere Pro also supports Panasonic DVX100 24p DV camera pulldown, called
24p Advance (24pA)
. This format is
used by some cameras to capture 23.976 progressive-scan imagery using standard DV tapes.
For more information about 24p pulldown schemes, see the video tutorial, Digital Video Principles: Converting 24 fps
video, on the
lynda.com Digital Video Principles - Converting 24 fps video
.
Chris Meyer provides links to resources about pulldown

on the ProVideo Coalition website.

From the Available Presets list on the Sequence Presets tab, choose the 24p preset that matches the frame aspect
ratio and audio sampling rate of most of your footage. 24p presets are located in the DV-24p, DVCPRO50 > 480i,
DVCPROHD > 1080i, and DVCPROHD > 720p folders.

If you capture 24p footage, Premiere Pro recognizes the footage as 24p and treats it accordingly, regardless of your
sequence settings.
