Motion Blur
The Motion Blur button is a global setting. Turning off Motion Blur temporarily disables motion
blur throughout the composition, regardless of any individual nodes for which it’s enabled. This
can significantly speed up renders to the viewer. Individual nodes must first have motion blur
enabled before this button has any effect.
Proxy
The Proxy setting is a draft mode used 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 Settings, found in the Fusion menu.
Auto Proxy
The Auto Proxy setting is a draft mode used 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 Settings found in the Fusion menu.
Selective Updates
When working in Fusion, only the tools needed to display the images in the viewer are updated.
The Selective Update options select the mode used during previews and final renders.
The options are available in the Fusion Preferences General panel. 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
many changes to a slow-to-render composition.
Transport Controls in Fusion Studio
The transport controls in Fusion Studio include buttons to control playback, time fields on the
left side for setting the global range and render range, and a Render button to initiate rendering
of the composite. There are also controls on the right side for proxy and motion blur. The time
field on the far right is used for the current time.
