To help with the audio sync issues, you can use the Conform feature to slow the video
back down to its original 24 fps rate. Because the conform process does not alter the
25 fps timecode created during the film transfer, you have the option of retaining that
timecode format while you edit in a 24 fps editing timebase. This can be useful for those
situations where your negative cutter prefers to receive a 25 fps EDL instead of a film cut
list for film match-back.
See
for more information about conforming video.
About the Timecode
When you conform 25 fps video to 24 fps, the clip’s timecode rate is defined as 24 @ 25.
Note: Because the timebase and playback are based on 24 fps, the 25 fps timecode no
longer accurately represents the true passage of time. For example, 38 seconds of video
will actually take 40 seconds to play.
You can see the timecode rate for a clip in the Item Properties window.
To verify a clip’s timecode rate
1
In the Browser, select the clip to be verified.

Do one of the following to open the Item Properties window:
• Choose Edit > Item Properties > Logging Info.
• Control-click the clip, then choose Item Properties > Logging Info from the shortcut
menu.
Clips that have been conformed from 25 fps to 24 fps display “24 @ 25” in the TC Rate
row.
About the Sequence Presets
There are two sequence presets designed for 24 fps PAL video:
• DV PAL 48 kHz - 24 @ 25: This preset uses a 24 fps editing timebase and 25 fps timecode
for both the source and record In and Out points, retaining the original source 25 fps
timecode. The DV PAL 24 @ 25 Easy Setup uses this sequence preset. When you export
an EDL, it will be based on 25 fps timecode values. This should be used when you intend
to export a 25 fps EDL and not a cut list.
• DV PAL 48 kHz - 24: This preset uses a 24 fps editing timebase and 24 fps timecode for
both the source and record In and Out points, replacing the original source 25 fps
timecode. This should be used when you intend to export a cut list.
