Fusion’s Place in the DaVinci Resolve
Image-Processing Pipeline
When working in a single unified environment like DaVinci Resolve, it is important to understand the
order of operations among the pages. DaVinci Resolve exposes some of this via the order of the page
buttons at the bottom of the screen, with the Media, Cut, and Edit page at the beginning of the chain
and the Color, Fairlight, and Deliver page at the end. However, this isn’t the whole story, especially
when it comes to the Fusion page. The following sections describe where the Fusion page fits in the
image-processing chain of DaVinci Resolve.
Source Media into the Fusion Page
For ordinary, single clips coming in from the Edit or Cut page, the MediaIn node in the Fusion page
represents the source media, as modified by the Clip Attributes window. Although you select the clip
from the Edit or Cut page Timeline, in the Fusion page, the clip is accessed from the Media Pool.
TIP: The decoding or debayering of RAW files occurs prior to all other operations, and as
such, any RAW adjustments will be displayed correctly in the Fusion page.
This means you have access to the entire source clip in the Fusion page, but the render range is set to
match the duration of the clip in the Timeline. You also use the full resolution of the source clip, even if
the Timeline is set to a lower resolution. However, none of the Edit or Cut page Inspector adjustments
carry over into the Fusion page, with the exception of the Lens Correction adjustment.
When you make Zoom, Position, Crop, or Stabilization changes in the Edit or Cut page, they are not
visible in the Fusion page. The same applies to any Resolve FX or OpenFX third-party plug-ins. If you
add these items to a clip in the Edit or Cut page, and then you open the Fusion page, you won’t see
them taking effect. All Edit and Cut page timeline effects and Inspector adjustments, with the
exception of the Lens Correction adjustment, are computedafterthe Fusion page butbeforethe Color
page. If you open the Color page, you’ll see the Edit and Cut page transforms and plug-ins applied to
that clip, effectively as an operation before the grading adjustments and effects you apply in the Color
page Node Editor.
With this in mind, the order of effects processing in the different pages of DaVinci Resolve can be
described as follows:
Source
Media
RAW
Debayering
Clip
Attributes
Fusion
Eects
Edit/Cut Page
Inspector
Adjustments
Edit/Cut
Plug-ins
Resolve FX
Color
Eects
TIP: Retiming applied to the clip in the Edit page Timeline is also not carried over into the
Fusion page.
Forcing Effects into the Fusion Page
There is a way you can force clips with Edit page Inspector adjustments, plug-ins, retiming, and Color
page grades into the Fusion page, and that is to turn that clip into a compound clip. When Edit page
effects and Color page grading are embedded within compound clips, MediaIn nodes corresponding
to compound clips route the effected clip into the Fusion page. However, bringing a compound clip
into the Fusion page does change the resolution of the source clip to match the Timeline resolution.
