Dragging a node from the Media Pool onto a connection (left), and dropping it to create a Merge node
composite (right).
The Node Editor is filled with shortcuts like this to help you build your compositions more
quickly. Here’s one for when you have a disconnected node that you want to composite against
another node with a Merge node. Drag a connection from the output of the node you want to
be the foreground layer, and drop it on top of the output of the node you want to be the
background layer. A Merge node will be automatically created to build that composite.
Remember: background inputs are orange, and foreground inputs are green.

Adding Clips to a Fusion Composition From the File System
If you drag clips from the file system directly into the Node Editor, they’ll be added to
the DaVinci Resolve Media Pool automatically. So, if you have a library of stock
animated background textures and you’ve just found one you want to use using your
file system’s search tools, you can simply drag it straight into the Node Editor and it’ll be
added to the currently selected bin of the Media Pool.
Fixing Problem Edges in a Composite
Most often, the Merge node does a perfectly good job when handed a foreground image with
premultiplied alpha transparency to composite against a solid background image. However,
from time to time, you may notice a small bit of fringing at the edge of the border of a
foreground element and transparent area, such as seen in the following close-up. This slight
lightening at the edge is a tell-tale sign that the clip probably wasn’t premultiplied. The Merge
node expects all foreground images with alpha channels to be premultiplied. But this is
something that’s easily fixed.
