Overview
Tracerizo is a free Fusion Fuse for DaVinci Resolve that finds bright or dark blobs in your footage and annotates them directly in the Fusion page. Choose the channel to analyze, set the threshold window, and tune blur, minimum blob size, and background rejection until exactly the right areas are tracked.
Display controls shape the result: coordinate labels with font, style, size, and offset controls; connecting lines that can be straight, curved, or dashed; and rectangle, circle, corner bracket, or crosshair markers. Each group has its own color with optional gradients, plus line taper, softness, and render subdivisions for clean strokes.
A View Detection Area mode shows the binary detection matte so you can dial in exactly what gets tracked, and look presets like Sci-Fi HUD, Minimal White, Neon, Blueprint, and Constellation get you started instantly. Tracerizo installs in one drag with the included Lua installer and is a free download.

Setup & help guide for Tracerizo Install, find it in Resolve, the controls, common problems, uninstall
Tracerizo, the blob tracking overlay Fuse. Detection is recalculated from image brightness; it is not a subject-mask or persistent identity tracker.
Install
- Extract the complete ZIP before installing. Keep its How to Install.txt beside the files.
- Resolve Studio / Fusion Studio: drag the supplied Lua Studio installer into the Fusion Nodes area, follow its prompts, then restart the application.
- Resolve Free: close Resolve and copy Tracerizo.fuse to your user Fuses folder. Create that folder if needed.
- Windows user Fuses folder: %AppData%\Blackmagic Design\DaVinci Resolve\Support\Fusion\Fuses
- macOS user Fuses folder: ~/Library/Application Support/Blackmagic Design/DaVinci Resolve/Fusion/Fuses/
- Restart Resolve. Use the instructions in your package if its installer or host version differs.
Where it appears in Resolve
Fusion → Shift+Space → Tracerizo. Connect video to its Input and connect its output to MediaOut. Start with View Detection Area to see which bright or dark regions are being found.
Controls in plain words
Some controls appear only after choosing the relevant mode.
Display and detection
- Enable
- Turns the effect on or passes the source through.
- Rectangles / Lines / Coords
- Shows or hides the shape markers, connecting lines and coordinate labels independently.
- View Detection Area
- Shows the detection matte instead of the normal annotated result.
- Video Opacity
- Fades the underlying footage while leaving annotations visible. It is skipped in detection-matte view.
- Look Preset
- Applies a ready-made combination of display settings, such as Sci-Fi HUD, Minimal White, Neon, Blueprint or Constellation.
- Track Source / Channel
- Looks for dark or bright regions, using luminance or an individual red, green or blue channel.
- Threshold Min / Threshold Max
- Limits the brightness range counted as a detected region.
- Background Reject
- Helps reject large background-like regions.
- Max Blob Count
- Limits how many regions receive annotations.
- Resolution
- Sets the sampling detail used to find regions. The analysis grid tops out at 160 × 90, which the default already reaches, so lower it only to trade detail for speed.
- Blur
- Smooths the detection input to reduce small noisy regions.
- Min Blob Size
- Ignores regions smaller than this limit.
Rectangles and connecting lines
- Rect Mode
- Chooses outlines, corner brackets, inverted video inside detected regions, or crosshairs.
- Max Rect Width / Max Rect Height
- Limits marker dimensions.
- Rectangle Thickness / Show As Circles / Corner Rounding
- Sets outline width, switches boxes to circles and rounds box corners.
- Crosshairs / Crosshair Size / Rotation / Thickness
- Enables and sizes, rotates and thickens crosshair markers.
- Line Mode
- Mesh connects neighboring regions; Hub Largest connects toward the largest region; Hub Center uses a central hub.
- Curved Lines / Dashed Lines
- Bends the connectors or breaks them into dashes.
- Write On
- Reveals a fraction of the connector paths. Animate it for a draw-on.
- Connecting Threshold
- Limits the distance over which regions connect.
- Line Thickness / Line Softness
- Sets connector width and edge softness.
- Render Subdivisions / Line Taper
- Sets curve smoothness and how much line ends narrow.
Text and colors
- Font / Style / Text Size
- Chooses the coordinate-label font, face and size.
- Text Offset X / Y / Text Tracking
- Moves labels away from their regions and changes letter spacing.
- Text Format / Decimal Places
- Chooses coordinates, numbered coordinates, percentages or numbers only, and the precision shown.
- Red / Green / Blue (rectangle, line and text groups)
- Sets each annotation group’s solid color independently.
- Gradient / Use Gradient
- Edits a group’s color ramp and enables it instead of the solid color.
- Gradient Offset / Gradient Focus
- Slides and concentrates the color transition.
- Gradient Rotation / Gradient Wrap
- Rotation turns the rectangles' gradient only. Wrap repeats the ramp; the text group also has Wrap.
- Clipizo on YouTube / YouTube
- Opens the Clipizo channel in your browser. It does not change the image.
Common problems
- Not in the tool search
- Extract the ZIP, check that the file still ends in .fuse, and restart Resolve after copying it. Use the user Fuses location for a manual install. Avoid installing a second copy of the same tool.
- An older interface still appears
- Resolve caches Fuse code. Fully restart it, then try a newly added node; an existing node may retain saved values.
- Too many boxes or none
- Enable View Detection Area. Choose the correct Track Source and Channel, then adjust the threshold window, Blur, Min Blob Size and Background Reject.
- Labels jump between objects
- Regions are detected each frame. Brightness changes, merging regions or changing size order can change the labels; this is not an identity tracker.
- Only a black-and-white image
- Turn View Detection Area off to return to the annotated video.
Uninstall
- Close Resolve / Fusion. Move only Tracerizo.fuse out of the Fuses folder where you installed it, to a backup folder outside the Fusion search folders.
- If you used the Studio installer, check the destination it reported (which can be the shared Clipizo/Fuses folder). Leave other Clipizo files in place.
- Restart the application. Existing projects using this tool will need it reinstalled to render the same result.
- If your installer also supplied a Tracerizo Edit effect, move its .setting and thumbnail out of Fusion/Templates/Edit/Effects/Clipizo/ too.
