Video object remover
Remove, blur, or pixelate objects in a clip — click-to-select with AI, draw a box, or one-click licence-plate detection, tracked across frames with per-edit undo.
The object remover lives in the Video Editor — open a clip on the timeline and find the Object remover panel. It removes, blurs, or pixelates a selected region on every frame it appears in, entirely on your device.
Selecting the object
Scrub the playhead to a frame where the object is clearly visible — the preview canvas shows the frame at the playhead. Then use one of three selection tools:
- Click object — a click hands the frame to SlimSAM, which outlines the object's full shape. Up to five clicks refine the outline; each click re-runs the segmentation with all points.
- Draw box — drag a rectangle over the region. No model involved; use it for text, signs, watermarks, or anything the segmenter misjudges.
- Plates — one click scans the frame with a pinned Apache-2.0 RT-DETRv2 licence-plate detector (a one-time ~81 MB download, plus potentially uncached shared ONNX Runtime assets). On apply, plates are re-detected throughout the clip rather than tracked from one frame, so moving vehicles stay covered. Selecting plates switches the effect to blur by default.
Remove, blur, or pixelate
- Remove fills the region using a temporal median: for each pixel, the pipeline samples nearby frames (the Temporal window slider, ±3–24 frames) where that pixel is not covered, and uses their median as the fill. A wider window is cleaner but slower.
- Blur applies a Gaussian blur (2–40 px) — the robust choice for plates, faces, and screens.
- Pixelate applies mosaic blocks (4–32 px) when the censoring should read clearly.
Edge feather (0–20 px) softens the boundary of any treatment.
Tracking
With Track the object enabled, the selected region is followed across frames by template matching. Tracking runs from the selected frame forward, follows movement but not rotation or size changes, and — if confidence stays low for several consecutive frames — freezes in place and flags the edit as tracking froze mid-clip instead of drifting off-target. Turn tracking off for fixed overlays such as watermarks and logos.
The AI patch (~196 MB, consent-gated)
Removal borrows background from frames where the spot is uncovered. If the area is never revealed — a static watermark over a static background — there is nothing to borrow. The optional AI patch runs LaMa, an inpainting model, to generate a plausible fill for those areas. It is a one-time download of roughly 196 MB and the tool asks before fetching, the same consent flow described in why AI tools download a model once. Without it, permanently covered spots keep their original pixels.
Applied edits, undo, and revert
Applying an edit re-processes the clip — audio is kept — and the result replaces the clip on the timeline, with -objects appended to the filename. Each edit is listed under Applied edits:
- ✕ on an edit re-renders the clip from the pre-edit original with the remaining edits replayed exactly as first applied (tracking offsets and plate boxes are recorded, so nothing re-tracks or drifts).
- Revert all restores the untouched clip.
Limits
- Removal fills need the background to be revealed in nearby frames or to hold still — moving-camera reconstruction is not attempted.
- Tracking follows movement only; rotation or scale changes cause a freeze-and-flag, not a stretch.
- Automatic detection covers licence plates only; other text and signs are a draw-a-box job.
- Processing runs at up to 1280 px on the long edge, matching the editor's other video pipelines.
