Rotating the tracking knob adjusts the position of the audio head so
you can improve the quality of the optical audio scan
When capturing optical audio, your reader will dim its LED light if the reader's film roller is not
turning. The reader conforms to the status of your scanner, so if the scanner enters sleep mode,
the reader will too.
Tracking with Magnetic Audio
The Audio and KeyKode Reader's magnetic audio head comes preconfigured from the factory
and shouldn't need adjustment. The nature of magnetic audio means that a small amount of
overlap shouldn't cause distortion as these areas don't carry magnetic information. There is also
typically less variation in the placement of magnetic soundtracks during the printing process, and
the reader's magnetic head is slightly oversize to help compensate for any misalignment.
Advanced Tracking
In addition to the tracking adjustments listed here, the reader also supports:
Magnetic audio azimuth and tracking adjustment
Optical audio azimuth adjustment
Optical audio focus adjustment
For most users, these changes will never be necessary. For information on these advanced
adjustments, contact your Blackmagic Support Center at
Commencing your Scan
Once you have set your audio type and adjusted the tracking, simply commence your scan
as detailed in the section named 'Scanning One or More Sections of Film.'
It's worth noting that DaVinci Resolve will not begin writing a file until it has synchonized audio
and video information being sent from your scanner. As audio information is printed a few frames
ahead of its corresponding frame, this means there will be a brief pause of approximately one
second between your scanner reaching speed and your scan appearing on screen.
