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.
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.
When you are done editing, you can use the Adobe Media Encoder
to export the 24p movie from Premiere Pro to Adobe Encore. You can
open it in Encore, author your DVD, then master and burn the project
as a 24p MPEG-2 stream. The resulting DVD exhibits no interlacing
artifacts on 480p-capable (progressive-scan-capable) DVD players
and televisions. Alternatively, you can export the Premiere Pro
24p project into a format, such as still-image sequences, appropriate
for transfer to film.
Note: Premiere Pro accepts 24p and 24pA footage only from cameras
using these schemes.
