MultiMerge
Multi-layer 2D compositing
Combines many 2D layers in one node and provides per-layer ordering, transform and blend controls.
MultiMerge
DaVinci Resolve · Fusion
MultiMerge is useful when a composition contains many independent 2D layers and a long Merge chain would become inconvenient.
Overview
What MultiMerge does
MultiMerge provides a layer-style view inside a node-based graph. Multiple foreground inputs can be managed in one node with per-layer visibility, ordering, transform and blend controls.
It can make motion-graphics assemblies more compact, especially when many simple elements share one composite. However, compact does not always mean clearer: complex logic can still be easier to debug as separate branches and Merge nodes.
Use MultiMerge when the layers conceptually belong together and benefit from central ordering. Use ordinary Merge nodes when branches have different processing or need clearer isolation.
Mental model
Think of MultiMerge as a small layer stack embedded inside the Fusion node graph.
Common uses
Assemble HUD graphics
Combine many title elements
Build compact motion-graphics layouts
Manage logo/icon stacks
Create grouped overlays
Reduce very long Merge chains

Output
The processed result from this node.
Inspector
Important parameters
Start with these controls before reaching for more complicated workarounds.
Selected Layer
Identifies the layer whose controls are currently displayed in the Inspector.
Enable / Disable Layer
Enables or disables the currently selected MultiMerge layer.
Layer Order
Controls front-to-back stacking.
Reorder layers without rewiring many Merge nodes.
Blend
Sets how strongly the processed result is mixed into the image.
Apply Mode
Per-layer blend mode.
Useful when some layers are lights, textures or shadows.
Operator
Chooses the compositing operator used by the selected layer.
Center
Sets center for MultiMerge.
X / Y
Sets the X and Y components of the control.
Size
Sets the overall size.
Angle
Sets the angle of the element.
Pivot
Sets the pivot used for rotation and scaling.
Move the pivot when the element needs to rotate or scale around a point other than its current center.
Flip / Flop
Flips the selected layer horizontally or vertically.
Filter Method
Selects the filtering method.
Chooses the resampling or filtering method used by the operation.
Edges
Controls how the operation treats image or region edges.
Use Alpha
Uses the foreground alpha channel when compositing the layer.
Pre-Multiply / Post-Multiply
Controls premultiplied-alpha handling around the operation.
Pre-divide removes alpha multiplication before processing; post-multiply restores it afterward. This is useful when color work creates dark or bright fringes around translucent edges.
Mask
Limits the selected MultiMerge layer with its connected mask.
Layer Transform
Per-layer position, scale and rotation.
Lets simple layout changes live directly inside MultiMerge.
Global Blend
Sets how strongly the processed result is mixed into the image.
Practical setup
A reliable workflow
- 1
Connect the base image.
- 2
Add foreground layers to MultiMerge.
- 3
Set their stacking order.
- 4
Adjust individual layer transforms and blend values.
- 5
Keep complex per-layer processing outside MultiMerge where it remains easy to inspect.

Troubleshooting
Common mistakes
Using MultiMerge for deeply processed branches and making troubleshooting harder.
Forgetting which internal layer contains an animation.
Treating it like Edit-page layers and losing the clarity of a node graph.
Production notes
Practical tips
Use MultiMerge for logically grouped simple layers.
Name source nodes clearly before feeding them into MultiMerge.
If debugging becomes difficult, break important layers back into explicit Merge nodes.
