24p sequences
About 24p footage and sequences
Footage acquired from a camcorder or by film transfer, at roughly 24 non-interlaced (progressive) fps is called 24p footage. This footage emulates
film in its picture quality and depiction of movement because the 24p frame rate is very close to that of motion-picture film, and each frame is built
from progressive lines (not from interlaced half-frame fields). 24p formats have become popular among low-budget digital filmmakers because they
lend a film look to its subjects.
To create a DV 24p sequence in Premiere Pro, you select the DV-24p sequence preset that matches the format and frame aspect ratio of your
footage. You can import files and capture footage as usual.
Premiere Pro includes two alternate 24p pulldown schemes for DV 24p: Repeat Frame and Interlaced Frame. Both options convert 24p footage so
that it plays back at 29.97 fps, but there are subtle visual and performance differences between them. You can select one of these options in the
New Sequence settings when starting a new DV-24p sequence, or change it in an existing sequence.
If you edit DV-24p footage in a sequence based on one of the standard Premiere Pro DV-NTSC presets, Premiere Pro uses a 24p DV pulldown
scheme to convert the footage to 29.97 fps interlaced video for playback to standard NTSC devices. You would use this method, for example, to
export your DV 24p movie to a standard NTSC format for mastering to tape or broadcasting.
If you edit 24p footage in a sequence based on one of the DV-24p presets, Premiere Pro, by default, manages the 24p pulldown scheme, so that
the video can be exported for playback on 24p NTSC devices. This allows you to export the movie to a file in a 24p format. You would use this
method, for example, to export your movie to a DVD for playback on DVD players and TV monitors that support 24p formats.
Premiere Pro accepts 24p and 24pA footage only from cameras using these schemes.
Not all 24p source media has a pulldown, nor does it necessarily require it. Many new formats are 24 progressive-native, (24pn).” No pulldown
scheme is applied to make them compatible with 30 fps video. Some P2 formats, all XDCAM and XDCAM-EX formats, and most AVCHD 24p
formats are progressive native.
About 3:2 and 24pA pulldown
When you transfer 24-fps film to 29.97-fps video, you use a process called 3:2 pulldown, in which the film frames are distributed across video
fields in a repeating 3:2 pattern. The first frame of film is copied to fields 1 and 2 of the first frame of video, and also to field 1 of the second video
frame. The second frame of film is then spread across the next two fields of video—field 2 of the second video frame and field 1 of the third frame
of video. This 3:2 pattern is repeated until four frames of film are spread over five frames of video, and then the pattern is repeated.
The 3:2 pulldown process results in whole frames (represented by a W) and split-field frames (represented by an S). The three whole video frames
contain two fields from the same film frame. The remaining two split-field frames contain a video frame from two different film frames. The two split-
field frames are always adjacent to each other.
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.
