How do I add motion tracking visuals to a video?

Upload your video. The tool detects moving objects and overlays tracking boxes, crosshairs, and connection lines. Adjust detection sensitivity and visual style, then export as MP4.

What is blob tracking?

A computer vision technique that identifies and follows regions of movement (blobs) in video. Common in interactive installations, VJ performances, and creative coding tools like TouchDesigner. This tool applies the visual look of blob tracking to any video.

Can I use blob tracker for VJ performances?

Yes. Export processed clips for Resolume, VDMX, or OBS. Tracking overlays on black or original footage work well for projection mapping and live visuals.

Is this real object detection or just a visual effect?

It uses real motion detection (frame differencing) to find moving areas, but the purpose is visual effect, not analysis. The tracking boxes follow actual movement in your video.

Blob Tracker

Blob Tracker detects and tracks moving objects in your videos, overlaying bounding boxes, crosshairs, and connection lines. Same look as blob tracking in TouchDesigner, but it runs in the browser with no install. Good for tech-themed content, music videos, and VJ sets.

How to use Blob Tracker

Upload a video clip (MP4, MOV, or WebM). Processing happens in your browser — nothing is uploaded to a server.
Adjust Detection Sensitivity. Lower values catch subtle motion; higher values only track large moves.
Pick an overlay style — bounding boxes, crosshairs, connection lines, or all three.
Choose overlay color and line weight to match your aesthetic (green for military, white for minimal, neon for VJ).
Scrub the timeline to preview. When the tracking looks right, click Export and save as MP4.

Tips

Works best on footage with clear movement against a stable background.
Lower sensitivity to detect subtle movements; raise it to track only large motion.
Green overlay on dark footage gives a military/surveillance look.
Pair with Night Vision for a security camera aesthetic.
