3
Click Playback Settings.
4
In the 24p Conversion Method pane, select one of the following options:
Repeat Frame (ABBCD)
Duplicates frames where necessary to maintain 29.97 fps playback. This option uses fewer
CPU resources.
Interlaced Frame (2:3:3:2)
Combines the frames in a telecine-like scheme to maintain 29.97 fps playback. This option
produces smooth playback but uses more CPU resources.
5
Click OK in the Playback Settings dialog box, and click OK in the New Sequence dialog box.
Disable 24p pulldown to simulate film-video transfer
By default, Premiere Pro uses a 24p pulldown scheme to play back 24p DV footage at 29.97 fps in a project based on
one of the NTSC presets. You can disable the pulldown scheme to give your movie the look of a film transferred to
video or broadcast, without frame interpolation.
1
Right-click (Windows) or Control-click (Mac OS) a 24p clip in the Project panel.
2
Select Modify > Interpret Footage.
3
Under Frame Rate, select Remove 24p DV Pulldown.
4
Click OK.
Additionally, you can apply any of a number of third-party film-look plug-in effects to the master sequence. These
plug-ins can often perform telecine-style conversion, or add grain or color correction to simulate various film stocks.
Pay close attention to lighting and, during shooting, use tripods and do slow pans to create the appearance of using a
heavy film camera. Attention to these details gives your project more of a film look.
Display 24p source timecode
When you import 24p footage, Premiere Pro treats it as 23.976 fps progressive footage. Because of this, when you work
with 24p footage in a 24p project, the timecode is displayed as 24 fps. However, the camera records and logs 24p
footage in 30 fps non-drop-frame timecode. When you log 24p footage for capture, you log clips according to the
camera’s timecode count of 30 fps non-drop-frame timecode.
For example, a clip that you log for capture may have an In point of 00:01:00:28. However, as an offline clip in a 24p
project, the In point is shown as 00:01:00:23. In addition, mixing non-drop-frame footage with drop-frame footage can
cause larger differences in timecode display between the project and the clip, with minutes, seconds, and entire
durations seemingly out of sync. Be aware of these discrepancies as you edit.
If you use 30 fps non-drop-frame timecode for projects containing 24p footage, Premiere Pro drops every fifth frame
from the 24p footage timecode count. When you view the properties of your 24p clip, the frame rate is shown as 23.976,
but the timebase as 29.97. If you’d prefer to read a clip’s original timecode, do the following:
1
Right-click (Windows) or Control-click (Mac OS) the clip in the Project panel.
2
Select Modify > Interpret Footage > Use Frame Rate from File.
