Extracting Audio
If the film you're scanning also contains an optical sound track, you can extract the audio in a
separate step. There is a standard image frame to audio frame offset of 26 frames for 16mm
and 21 frames for 35mm that DaVinci automatically aligns when extracting the audio. Select
all of the clips that have an optical sound track, then right-click one of the selected clips and
choose 'extract audio'. Resolve analyzes the overlapping optical track area of each frame and
automatically generates a matching audio track, synchronized with the scanned
image sequence.
Each clip's audio will be automatically extracted, embedded in the clip and saved to the same
directory the scanned frames have been written to. A small audio icon will appear on the corner
of your clip's thumbnail so you know there is a corresponding audio file.
To make extraction easier, you can filter the clips in the media storage by name, resolution,
date modified or by film clips only. Filtering your clips makes it easier for you to find and select
exactly what you need. You can also make a large selection and extract audio from multiple
clips at once by right clicking on your selection and choosing 'extract audio...' from the menu.
During audio extraction, an information box indicates the progress. You can click the 'stop'
button any time to stop the extraction.
You can filter the contents in the media storage to make it easier to manage them.
If the 'timestamp prefix' checkbox was deselected in the 'capture info' section when your clips
were scanned, and you want to have extracted audio automatically embedded in your clips,
always remember to extract audio from the clips inside the media pool.
