Purpose
One node can express a complete operation
Krokodove began as an external Fusion tool collection. Blackmagic integrated its tools into Fusion and Edit Effects in Resolve 21, then added over 25 more Shape and 3D tools in 21.1. A modern introduction therefore starts with the capabilities of your installed Resolve version; instructions for copying a plugin belong to the separate legacy branch.
The useful distinction is how an operation is controlled. Fragments controls the appearance of image pieces through ranges, Seamless Loop joins the end and beginning of an animation, and Mapped Duplicate 3D distributes changes across copies using a map. Merge, Transform, masks, cameras and a renderer connect those operations to the rest of the composition.
Starting points
Start with the result the shot needs
Choose one task and explore the relevant pair of tools. This makes it easier to understand what enters the node, what each control changes and where Krokodove hands the result back to the composition.
A background, grid or screen texture
Pattern creates geometry itself; Rasterize turns an input image into dots or other stamps. Choose according to whether you need a new pattern or a recognizable source represented through a pattern.
A title or logo reveal
Fragments suits a mosaic reveal of individual pieces. Grow spreads a reveal from seed points through a selected channel. Prepare alpha before the effect and inspect the result against the actual background.
A loop or digital treatment
Seamless Loop addresses the temporal seam, Channel Shifter separates channels, and Sort rearranges pixels by value. These are different operations: add them one at a time and keep the source branch available for comparison.
An object array or procedural animation
Mapped Duplicate 3D takes a 3D object and a control image. Beat, Random and text modifiers drive a parameter; they attach to a control rather than occupying a place between Image and Merge.
Connections
The collection name does not determine the output type
Before connecting nodes, identify whether the branch carries pixels, Shape data, a 3D scene or a parameter value. A connector color helps within a particular tool, but matching colors across different systems do not guarantee compatibility.
| Tool type | What it receives | Where the result goes |
|---|---|---|
| Generator: Pattern, Lines | Pattern and canvas settings; source footage is not required | A regular 2D effect, Merge or MediaOut |
| Image processor: Fragments, Sort, Rasterize | A 2D image; some tools have a separate map or mask | A 2D image for further processing and compositing |
| Mapped Duplicate 3D | A 3D object in SceneInput; an image separately in Map | Merge3D → Renderer3D → 2D compositing |
| Shape tools, including the 21.1 expansion | Generator settings or compatible Shape input data | sRender for 2D, or a supported bridge into 3D |
| Beat, Random, Write and other modifiers | A parameter control or text field | That control's value over time |
First composite
Build one readable effect
A short title composition is enough for a first exercise. It demonstrates the basic structure: a source prepares the image, a specialized node changes it, and Merge combines it with a background.
Prepare the source
Create Text+ on a transparent background and view its Alpha channel. Feed Text+ into the main image input of Fragments. If the effect breaks up a solid rectangle, fix the source alpha first.
Set up one operation
Choose Alpha as the selection channel, establish a readable fragment size and animate the active Range Fade interval. First achieve a clear letter reveal without additional glow.
Build the output
Connect Fragments to Merge.Foreground, footage or Background to Merge.Background, and Merge to MediaOut. After checking transparency, add Glow to the title branch and inspect the beginning, middle and end of the animation.
Catalog scope
61 entries describe the base Resolve 21 table
This section's catalog follows the brief table in the April 2026 Resolve 21 New Features Guide: 61 names across 10 groups, including modifiers. It provides a traceable navigation baseline, rather than an exhaustive inventory of the current 21.x library.
The official September 8, 2026 release announces over 25 additional Krokodove tools in Resolve 21.1. If a tutorial uses a new Shape or 3D tool, having the original Pattern and Fragments in 21.0 does not establish compatibility with the whole tutorial.
Blackmagic refers to over 70 new graphics and over 100 effects and tools without explaining the counting method. The exact relationship between these figures has not been established. They should not be added to the 61 guide entries or presented as the number of individual encyclopedia articles.
