You can tell if the audio track is optical by inspecting the film. If you're scanning 35mm or 16mm
film and see a continuous waveform or a long, tightly packed series of stripes down one side,
your print has an optical soundtrack.
Optical Audio Narrow Track
When scanning optical audio, film shrinkage and the variables inherent in printing will
occasionally mean that your film's optical soundtrack is smaller than the area scanned by your
Audio and KeyKode Reader. This can result in the audio reader scanning perforations or image
data on either side of the sound track, which causes interference in the audio. In this event,
adjusting the reader's tracking knob can help improve the audio, but if that is unsuccessful and
the audio track is problematic, then you can select 'optical audio narrow track' from the 'use
film' menu. This will reduce the area your reader scans by about twenty percent, limiting the
unwanted areas around the optical track and improving the quality of the audio scan.
For more information about the tracking feature on the audio reader, refer to the 'tracking'
information later in this section.
Magnetic Audio
If you want to scan the magnetic striped audio track on 16mm film, set the 'use film' setting to
'magnetic audio'.
You can identify magnetic striped audio audio track on 16mm film by looking for a black strip
next to the frames. The black strip will be copper colored on the emulsion side of the film.
NOTE When scanning magnetic stripe audio, we recommend setting your scan speed
to 24 frames per second for proper equalization. Scanning at other speeds may require
pitch adjustment in post.
Audio Type
Once you have selected the appropriate 'use film' option, choose your audio type from the
'audio type' menu.
Stereo or Mono Audio
You can easily tell whether optical audio is stereo or mono by inspecting your film. If you see
two waveforms side by side, your film has a stereo soundtrack. If you only see one waveform, or
the packed stripes of variable density audio, your film has a mono soundtrack. Magnetic audio
is always mono.
Choose 'stereo' or 'mono' audio depending
on the type of audio on the film
