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 24p sequence in Premiere Pro, you select the 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: 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 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.
