Prx
A draft mode to speed processing while you’re building your composite. Turning on Proxy
reduces the resolution of the images that are rendered to the viewer, speeding render times by
causing only one out of every x pixels to be processed, rather than processing every pixel. The
value of x is decided by adjusting a slider in the General panel of the Fusion Preferences, found
under the Fusion menu on macOS or the File menu on Windows and Linux.
Aprx
A draft mode to speed processing while you’re building your composite. Turning on Auto Proxy
reduces the resolution of the image while you click and drag to adjust a parameter. Once you
release that control, the image snaps back to its original resolution. This lets you adjust
processor-intensive operations more smoothly, without the wait for every frame to render at full
quality causing jerkiness. You can set the auto proxy ratio by adjusting a slider in the General
panel of the Fusion Preferences, found under the Fusion menu on macOS or the File menu on
Windows and Linux.
Selective Updates
The last of the five buttons on the right of the Transport Controls is a three-way toggle that
determines when nodes update images in the viewer. By default, when working in Fusion, any
node needed to display the image in the viewer is updated. The Selective Update button can
change this behavior during previews and final renders.
The three options are:
Update All (All): Forces all the nodes in the current node tree to render. This is primarily
used when you want to update all the thumbnails displayed in the Node Editor.
Selective (Some): Causes only nodes that directly contribute to the current image to
be rendered. So named because only selective nodes are rendered. This is the default
setting.
No Update (None): Prevents rendering altogether, which can be handy for making a lot
of changes to a slow-to-render composition.
The options are also available in the Fusion Preferences General panel.
Changing the Time Display Format
By default, all time fields and markers in Fusion count in frames, but you can also set the time
display to SMPTE timecode or Feet + Frames.
To change the time display format:
1 Choose Fusion > Fusion Settings in DaVinci Resolve, choose Fusion Studio >
Preferences in Fusion Studio on macOS, or choose File > Preferences in Fusion Studio
on Windows or Linux.
2 When the Fusion settings dialog opens, select the Global and Default settings >
Defaults panel and choose a Timecode option.
3 Select the Frame Format panel. If you’re using timecode, choose a frame rate and turn
on the “has fields” checkbox if your project is interlaced. If you’re using feet and frames,
set the Film Size value to match the number of frames found in a foot of film in the
format used in your project.
4 Click Save.
