Optical Audio Narrow Track:
‚
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:
‚
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
Stereo or Mono Audio:
‚
choose your audio type from the 'audio type' menu. 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
