Controlling Node Caching
You can manually control which nodes in a grade are cached, and which are not. Right-click any
node in a node tree, and choose an option from the Node Cache submenu. There are
three options:
 Auto: The flagged node and all upstream nodes will only be cached in Smart mode if it
contains an operation that’s designated for caching.
 On: The node will always be cached in either Smart or User mode, no matter what
operations it performs.
 Off: The node will not be cached, in either Smart or User modes. This lets you exclude
nodes from caching in Smart mode if they’re capable of real time operation on your
system.
Controlling Color Output Caching
Each clip in the Timeline has a Color Output setting that you can turn on or off by right-clicking
that clip in the Timeline of the Edit page, and choosing Render Cache Color Output from the
contextual menu. A check mark indicates when this setting is turned on.
Controlling Edit Page Filter Caching
You can choose which of the ResolveFX or OFX filters applied to a particular clip should be
cached by right-clicking that clip in the Timeline of the Edit page, and choosing which of the
filters in the Render Cache OFX Filter submenu you want to cache.
Each filter applied to that clip appears in this submenu in the order in which it’s applied to the
clip, and you can turn the caching of specific filters on and off (selected filters appear with a
check mark to the left of their menu item).
Clearing Cached Media
Each project’s cache is persistent; the cache is saved for future use even when the project is
closed and later reopened. If you need to delete a project’s cache to free up space on a
storage volume, there are three options in the Delete Render Cache submenu:
 All: You can delete all media in the cache to reset every single cached clip.
 Unused: You can choose to delete only Unused cache clips that no longer correspond
to clips or effects in the Timeline.
 Selected clips: You can make a manual selection of clips in the Timeline, and delete
the cache corresponding to just those clips.
To clear a project’s cache:
Open the project, and choose Playback > Delete Render Cache > All, Unused, or
Selected Clips.
Using Cached Media When Rendering in the Deliver Page
The “Use Render Cached Images” option in the “More options” section of the Video panel of
the Render Settings in the Deliver page lets you write media directly from the cache, rather than
re-rendering the effects from scratch, in order to save rendering time when you output your
project. If you’re planning on using this option, it’s advisable to set the cache format to a suitably
high-quality format to guarantee the best results.
