Cache Color Output Is Actually Node Caching for the Whole Grade
 In Smart mode: Manually flagged clips with Render Cache Color Output turned on
cache the entire output of the Color page node graph, effectively caching that clip’s
entire grade. This is most useful when you want to improve trimming and playback
performance in the Edit page. Flagging a clip for caching also causes EVERY SINGLE
VERSION associated with that clip to be cached as well.
 In User mode: Manually flagged clips with Render Cache Color Output turned on also
cache the entire output of the Color page node graph.
Caching of ResolveFX and OFX in the Edit Page Is Also Node Caching
Caching of ResolveFX and OFX filters applied to clips in the Edit page can only be set
manually, whether you’re in Smart or User mode. Only filters that you have flagged to
cache by right-clicking the clip they’re applied to and choosing them in the Render
Cache OFX Filter submenu are cached.
Sequence Caching
 In Smart mode: DaVinci Resolve automatically caches all superimposed clips that use
composite modes other than “Normal,” any clips with opacity or speed effects, and any
transitions. Clips cannot be manually flagged for Sequence caching.
 In User mode: If you’ve enabled User mode and you find that your workstation does
not have adequate performance to play composite and opacity effects in the Edit page,
you can force these categories of effects to be automatically cached in User mode
via a set checkboxes in the Optimized Media and Render Cache section of the Master
Settings of the Project Settings. When these options are enabled, you also gain the
ability to exclude specific tracks from being cached, by right-clicking the track header
of any video track you want to exclude from caching, and choosing Exclude track from
caching. Excluding an entire track from caching is a convenient way of keeping a track
full of effects that are capable of playing in real time on your workstation, such as a
track of titles, from wasting time and storage by being cached when it’s not necessary.
Manually Controlling the Cache
This section describes how to manually control each type of caching that is manually
controllable in DaVinci Resolve.
Controlling Fusion Output Caching
You can manually control which clips in the Timeline are cached, and which are not. You can
select one or more clips in the Timeline of the Edit page, or in the Thumbnail Timeline of the
Color page, right-click one of the selected clips or thumbnails, and choose an option from the
Render Cache Fusion Output submenu. There are three options:
 Auto: The clip will only be cached in Smart mode if it’s a format designated for caching
or if there’s a speed effect applied. The clip will only be cached in User Mode if
“Automatically cache transitions in User Mode” is enabled.
 On: The clip will be cached in either Smart or User mode, no matter what format or
effects are applied.
 Off: The clip will not be cached at all, in either Smart or User modes.
