Inside the box is a thin red line. This line is the mid point detector which detects the separation
between stereo audio channels. When mono sound is detected during audio extraction, the
mid point detector disappears and the guides will adjust automatically to suit the width of the
mono optical track.
TIP
If you need a closer inspection of the audio scan area guides, you can zoom into
the viewer and move the viewer position up or down, and left or right. Simply choose
the amount of zoom from the sizing options at the top left corner of the viewer, then
click and drag the viewer with your mouse or track pad.
When 'show audio scan area' setting is turned on, the audio area guides will be visible so
you can see exactly what information is being used and monitor the extraction process
Override Audio Scan Area
This setting provides sliders for adjusting the horizontal and vertical positioning, width,
and height of the audio scan area guides.
These settings include:
Left and Width
If your film type is such that audio appears on the right side of the frame, you can simply adjust the
'left' slider to move the guide box to the right. Normally, this will happen automatically if you have
the corresponding film type selected, but the setting gives you more flexibility for adjustments if
you need it. Similarly, the 'width' setting is used to adjust the width of the scan area.
These are helpful tools for making subtle adjustments to the side edges of the guide box if
there are unwanted elements inside the film's optical audio area. This can happen due to
perforation wear and tear, or varying print qualities, and can sometimes interfere with the
quality of the audio extraction. You can help avoid this by making a subtle movement to the
side edges to keep the stray elements outside of the guide box.
