What is the Blob Tracker effect?
Blob Tracker detects connected regions in an image or video and draws tracking overlays around them.
What can it track?
It can track bright or keyed regions, depending on the selected key color, threshold, and persistence settings.
Which overlays are available?
You can draw full boxes, corner boxes, circles, center markers, captions, and connecting lines.
Can I customize the tracking style?
Yes. Adjust box color, palette, blend mode, thickness, opacity, fill, caption placement, line type, and line style.
Does Blob Tracker work on videos?
Yes. Blob Tracker processes video in real time and keeps track IDs stable across frames.
Can I preview the detection mask?
Yes. Enable debug mask to see the mask that the blob tracker uses for detection.
Can I use Blob Tracker in Photoshop?
The tracker draws its boxes, labels and paths from motion across frames, and a Photoshop layer is one frame. The Photoshop plugin annotates that single frame; tracking over time belongs in the browser or the desktop app.
