Use MIDI Audio Console: A checkbox lets you enable the use of a third-party
audio console that’s connected to your workstation. Turning this on exposes three
additionalmenus.
MIDI Protocol: Lets you choose either the HUI or MCU protocol, whichever is
compatible with the audio console you want to use.
MIDI Input: Lets you choose the MIDI input used to connect your console.
MIDI Output: Lets you choose the MIDI output used to connect your console.
General
This panel provides various options for scripting, audio processing, monitoring, and sending
problem reports.
External Scripting Using: (Resolve Studio only) Options include None, Local, and
Network. When set to None, only scripting in the Console window is allowed. When
set to Local, external scripts and applications on the same computer can control
DaVinci Resolve. When set to Network, external scripts and applications from other
computers on the network (or via the internet) can control DaVinci Resolve.
Audio Processing Block Size: Lets you increase the sample block size to add
processing headroom to the system, at the expense of adding latency to audio
playback. The default value is Auto, which automatically chooses a suitable setting for
the audio I/O device you’re using.
For those who have specific needs and are interested in setting this manually, here are
some examples of use. In a first example, when a system is under a heavy load (there
are many plug-ins being used on many tracks), then increasing the block size to add
processing headroom will result in a longer delay every time your audio hardware
requests samples to feed the speakers. If you’re only mixing, the resultant latency may
not be a problem, so this gives you the option to add headroom so your system can run
a few more plug-ins or tracks.
On the other hand, this increased delay in the processed audio running through the
mixer is a much bigger problem if you’re recording an artist in an ADR session, where
they need to hear themselves in the headphones, or when you’re recording foley or
voice over and there’s an increased delay between what you see and what you’re
recording, so in this case sticking with the default value (or smaller) will sacrifice
processing headroom for diminished latency.
TIP: A common strategy when you need to force more cooperation from a
particular combination of workstation and audio interface is to reduce
Audio Processing Block Size when you’re about to do a recording session,
when track and plug-in use is lower. Later, when you start mixing in earnest
and adding plug-ins, you can increase Audio Processing Block Size to give
you better performance once you’re finished recording.
Use 10-bit precision in viewers if available: This checkbox only appears on Mac OS X
10.11 (El Capitan) and higher installations of DaVinci Resolve. Turning this checkbox on
lets DaVinci Resolve display 10-bit images in the Viewer.
