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:
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.
Top:
This setting adjusts the vertical position of the guide box.
Height:
Sometimes film frames on older rolls of film may be slightly smaller than normal
due to shrinkage over time. When making manual adjustments to the guide box, you
can make adjustments for film shrinkage using the 'height' slider.
Auto adjust audio scan height:
the guide box height to align with the audio waveform at the top of each frame. The
automatic feature works well for normal audio conditions, however, if during extraction
you notice the box moving randomly and the quality of the extraction is affected, it may
be due to similar features in the audio track overlapping between frames. If this occurs,
deselect the checkbox and try the extraction again.
If deselecting the 'Auto adjust audio scan height' checkbox, make sure the 'height'
setting places the guide box at the optimal position for the frame. Making manual
adjustments can help if you need them, but don't forget to turn the automatic features
back on afterwards!
Audio waveform color is white:
waveform may be black or white. If the waveform is white, make sure the corresponding
checkbox is enabled. This will ensure the white information in the waveform is used
during audio extraction. If the waveform is black and the surrounding audio area is
white, disable the checkbox so DaVinci knows to use the black information in the
waveform. Other automatic features, such as mid point and mono detection, also rely
on this setting being set correctly.
Override firmware stability:
created large movements in the frame due to the internal firmware stabilization.
This can cause the audio extraction guide box to misalign with the optical track. If
this occurs, enabling 'override firmware stability' lets the audio extraction guide box
track the film perforations independently and adjust its positioning for potentially
better results.
Variable density audio:
select the 'Variable density audio' checkbox so DaVinci Resolve knows the type of
audio to extract. The default state is set to 'off' for variable area audio soundtracks.
If you haven't used variable density audio before, you can visually identify it as a tight
sequence of shaded lines, similar to a bar code with the lines squeezed closer together.
By comparison, 'variable area' soundtracks appear as an audio waveform.
If your film type is such that audio appears on the right side of
