User Manual

The Proxy menu sets the ratio for skipping
pixels when processing.
The Auto Proxy button enables Fusion to interactively degrade the image only while
adjustments are made. The image returns to normal resolution when the control is released.
Similar to the Prx button in Fusion Studio, you can set the Auto Proxy ratio by right-clicking the
APrx button and choosing a ratio from the menu.
When a Loader node is selected, the Inspector includes a Proxy Filename field where you can
specify a clip that will be loaded when the Proxy mode is enabled. This allows smaller versions
of the image to be loaded to speed up file I/O from disk and processing. This is particularly
useful when working with high resolution files like EXR that might be stored on a remote server.
Lower resolution versions of the elements can be stored locally, reducing network bandwidth,
interactive render times, and memory usage.
The proxy clip that you create must have the same number of frames as the original clip, and if
using image sequences, the sequence numbers for the clip must start and end on the same
frame numbers. If the proxies are the same format as the original files, the proxies will use the
same format options in the Inspector as the originals.
Presetting Proxy Quality
When using Fusion Studio, rather than right-clicking over the Proxy button to set the proxy
quality, you can preset the standard and Auto Proxy quality in the Fusion Preferences window.
The General pane in the Preferences window includes sliders for both standard Proxy files and
Auto Proxy files. These sliders designate the default ratio used to create proxies when the
Proxy and Auto Proxy modes are turned on. These settings do not affect the final render quality.
TIP: Even though the proxies are being processed smaller than their original size, the
viewers scale the images so they refer to original resolutions.
