How do I add tracking overlays to a clip?

Drop the clip in, set sensitivity, pick boxes / crosshairs / lines, export MP4.

What is blob tracking?

The tracking-overlay look you see in surveillance graphics and tech-themed visuals. Boxes follow whatever is moving in the frame.

Can I use it for VJ sets?

Yes. Export the MP4 and drop it into Resolume, VDMX or OBS. Overlay reads well on black or over the original footage.

Does the tracking follow real movement?

Yes, the boxes lock onto actual motion in the clip, not faked. The point is the look, not analysis.

Blob Tracker

Blob Tracker draws tracking overlays on whatever moves in your clip: bounding boxes, crosshairs, IDs, connection lines. The look comes out of TouchDesigner work and surveillance-tech graphics. Use it on tech-themed content 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 when the subject moves against a stable background.
Drop sensitivity to catch small movement; raise it to lock only on big motion.
Green overlay on dark footage reads as military / surveillance.
Stack with Night Vision for a security-camera read.
