Choosing an Audio Timecode Format
Unlike video or film, which must be structured with a specific frame rate, audio is linear
with no physical frame boundaries. Adding timecode to audio is simply a way to identify
points in time, making it easier to match the audio to video or film frames.
During the shoot, you have the choice of which audio timecode standard to use (typically
30 fps, 29.97 fps, 25 fps, 24 fps, or 23.98 fps). You also have the choice, with 30 fps and
29.97 fps, of using drop frame or non-drop frame timecode. For NTSC transfers, it is highly
recommended that you use non-drop frame timecode for both the video and audio
(although Cinema Tools can work with either). See
About NTSC Timecode for more
information about drop frame and non-drop frame timecode.
A consideration for the audio timecode setting is how the final audio will be mixed:
• If the final mix is to be completed using Final Cut Pro: The setting needs to match the
Final Cut Pro Editing Timebase setting in the Sequence Preset Editor.
• If the final mix is to be completed at an audio post-production facility: The timecode needs
to be compatible with the facility’s equipment.
Note: Make sure to consult with the facility and make this determination before the shoot
begins.
In general, if you are syncing the audio during the telecine transfer, the timecode should
match the video standard (29.97 fps for NTSC, 25 fps for PAL, or 24 fps for 24p). Check
with your sound editor before you shoot to make sure the editor is comfortable with your
choice.
Mixing the Final Audio
The way you mix the final audio depends on how complicated the soundtrack is (multiple
tracks, sound effects, and overdubbing all add to its complexity) and your budget. You
can either finish the audio with Final Cut Pro or have it finished at a post-production
facility.
Finishing the Audio with Final Cut Pro
If you capture high-quality audio clips, you can finish the audio for your project with
Final Cut Pro, which includes sophisticated audio editing tools. Keep in mind, however,
that good audio is crucial to a good film, and a decision not to put your audio in the
hands of an audio post-production facility familiar with the issues of creating audio for
film might lead to disappointing results.
