Drag a box around an object, then track its motion.

Tracked objects

Keep up to six independent paths.

Your selected objects will appear here.

Choose a tracking box to edit its name, color, or position.

Correction timeline

Choose an object to review its corrections.

No corrections yet.

Editing a correction invalidates only the generated section it affects. Undo restores the original points.

Only tracking samples inside the selected range are replaced. Manual corrections and samples outside are preserved. Each tracked object needs a visible correction in the range.

The browser tracker matches image patches, not semantic identities. Optional size adaptation makes small per-frame adjustments; it does not recognize object identity. Low-texture objects, occlusion, scene cuts and fast motion can lose tracking. Reposition the box at a later frame to correct its path.

The motion trail will appear here after tracking.

Manual corrections

Pause and draw a new tracking box, or use the selected object's coordinate inputs at the current time. Mark a frame lost during occlusion, then draw a visible correction when the object reappears. Re-run tracking to propagate corrections.

Export & handoff

Coordinates in original video pixels.

CSV uses top-left origin, increasing X rightward and Y downward. Quality reports measure only visible sampled intervals; they cannot establish true video-wide coverage. Lost samples contain blank coordinate fields rather than fabricated positions. JSON includes paths and video metadata, not the video itself.

HOW IT WORKS

Turn movement into usable coordinates

Open footage

Load a browser-compatible video or the included sample. No video is uploaded to PixelOkay.

Define & track

Pause on an object and draw its box. Run patch matching, inspect confidence and add correction points if it drifts.

Export your work

Save raw pixel coordinates, portable project JSON, transparent trails, annotated stills or a silent WebM clip.

Accuracy and privacy

The offline tracker uses visual template matching; it is not a trained neural tracker and cannot reliably maintain identity through occlusion, scale changes or camera cuts. Optional AI object detection downloads a public MediaPipe model from an external host only after you explicitly choose Download & Load in Model Setup, then runs on-device. Video remains local. Video export is silent and plays in real time; MP4 and fully automatic identity re-identification are not included.

Using Video Object Tracker

Track up to six manually selected objects through sampled video frames and export their positions as motion paths. Optional object detection can propose starting boxes on one frame; template tracking and manual review create the path.

Import a clip up to three minutes and draw a starting box for each object, or request optional one-frame AI proposals after model setup.

Choose a sampling rate, start tracking and inspect the path for lost or drifting samples; add corrections or retrack a bounded interval where needed.

Export a CSV in source-pixel coordinates, SVG/PNG overlays, a quality report, a project JSON or a silent annotated WebM.

Example: Track a cyclist across an unobstructed eight-second clip at 5 samples per second, review the marker where the rider passes behind a sign, add a correction and export the CSV path for another workflow.

Limits and privacy: Tracking supports up to six objects, 180 seconds and 1,800 sampled intervals; gaps marked lost are not measured positions. Template matching does not re-identify an object after long occlusion. Optional MediaPipe setup downloads code, WASM and model assets from external hosts; detection proposals use a selected frame, while video processing stays in the browser. WebM output is silent and browser-dependent.

Frequently asked questions

Does optional AI track an object through the whole video?

No. The detector proposes boxes from a selected frame. Template matching follows the reviewed boxes across sampled frames and does not provide identity re-identification.

Are CSV positions expressed in pixels?

Yes. CSV coordinates use the source video’s pixel dimensions. Lost samples and gaps are marked or excluded rather than reported as observed positions.
