A Background node determines the output resolution of the merge.
The Background node sets the output size, and the foreground image is cropped if it is larger.
A Background node created at 1280 x 720 crops the larger foreground.
However, all the pixels of the larger foreground are available for repositioning.
Sizing Between DaVinci Resolve Pages
The order of sizing operations between DaVinci Resolve pages is a bit more nuanced. It’s
important to understand which sizing operations happen in the Fusion page, and which happen
after, so you know which effects alter the image that’s input to the Fusion page, and which
effects alter the page’s output. For example, lens correction, while not strictly sizing, is
nonetheless an effect that changes how the image begins in your Fusion composition.
However, the Edit or Cut page stabilization function is an effect that comes after the Fusion
page, so it does not appear in the composition you’re creating.
The order of sizing effects in the different pages of DaVinci Resolve can be described
as follows:
Edit/Cut Page
Transforms
Input
Sizing
Output
Sizing
Super
Scale
Edit/Cut Page
Lens

Sizing with Compound and Fusion Clips
Another way to modify the resolution before clips get handed off from the Edit page to the
Fusion page is to create a compound clip or a Fusion clip. Both compound clips and Fusion
clips change the working resolution of the individual clips to match the Timeline resolution.
Forinstance, if two 4K clips are stacked one on top of the other in an HD timeline, creating a
compound or Fusion clip resizes the clips to HD. The full resolution of the individual 4K clips is
not available in Fusion and is therefore handed off to the Color page at the rescaled size.
