Pick something in your video and the camera locks onto it: a bike, a helmet, a person, a dog… It stays fixed on screen while the world moves around it. Your file never leaves your device.
Written over the comparison. Leave one empty to hide it.
Pause the video and tap what you want to follow. Tapping one of the boxes is enough; the panel closes when you pick.
Tracking Effect is a free online tool that follows an object in your video and crops the frame around it. In Locked mode the object stays fixed in the middle at the same size while the world moves around it — the lock-on effect from the "bike tracking or helmet tracking?" Reels. Smooth mode keeps it in frame with a calm camera when you turn a horizontal video vertical. It finds people, motorbikes, cars, bicycles, dogs, birds, balls and 70 more kinds of objects by itself. No watermark, no sign-up; your video is not uploaded anywhere.
What is the lock-on effect?
The camera looks locked onto one thing: it stays in the same spot and size on screen in every frame, even as it moves. It is popular for motorbike, sport, dance and pet videos.
Does it jump to another rider passing by?
No. The object is recognised by its kind, size, position and colours; when it leaves the frame the view widens instead of grabbing the next thing.
Is it like CapCut or After Effects motion tracking?
It does the tracking part automatically in your browser: no keyframes, no tracking points to place.
Is my video uploaded?
No. Detection, tracking and the export all run on your device.
