NSS Background Remover
The NSS Background Remover video editor, end to end
Go beyond per-frame removal: color-grade, add LUT filters and text overlays, trim and fade on a timeline, work with layers and lifestyle scenes, and export — all on-device, frame by frame.
NSS Background Remover is not only an image tool — its video editor brings the same ideas to a timeline. It does per-frame background removal with solid, blurred, or custom backgrounds, and adds color grading, LUT-style filters, text overlays, trimming and fades, layers, lifestyle scenes, and export to MP4 or WebM.
This tutorial walks the video editor end to end. As with images, the model runs on your device, frame by frame, with temporal smoothing to keep edges from chattering — and nothing about your clip leaves the machine.

1. Open the video editor and load a clip
Open the video editor directly from the tool and load your clip. The first time, the model caches into your browser; after that it processes locally, frame by frame, with no upload.
The editor supports full-length playback, so you can work with the whole clip rather than a short preview.
- Per-frame background removal runs on-device.
- Inputs: MP4, WebM, MOV and more.

2. Remove the background and choose what replaces it
Run background removal across the clip and choose the replacement: keep it transparent, use a solid or blurred background, or drop in a custom background. Temporal smoothing keeps the cutout stable between frames so edges do not chatter.
For product or talking-head clips, a clean cutout plus a chosen background is often the whole job.
- Solid, blurred, or custom backgrounds.
- Temporal smoothing stabilizes edges across frames.

3. Grade and filter the footage
Use the color-grading sliders and LUT-style filters to set the look — sepia, faded film, high contrast, cool or warm treatments, and more. Because the editor is layer-aware, you can grade the subject independently of the background to make a composite believable.
Grading is where a technically clean cutout becomes a shot that looks like it belongs.
- Color-grade sliders plus LUT preset filters.
- Grade the subject and background separately for believable composites.

4. Add text, trim, and fade on the timeline
Add text overlays, then use the timeline to trim the clip and add fades. These are the finishing moves that turn a processed clip into a deliverable — a titled, trimmed, cleanly-faded video.
Layers let you stack the subject, background, and text, and reorder or adjust them without flattening everything into one destructive pass.
- Text overlays, timeline trim, and fades.
- Layered composition with reordering and adjustment.

5. Drop into a lifestyle scene (optional) and export
The lifestyle scenes available for images also appear in the video editor, so you can place a subject into a believable setting in motion. When the clip is ready, export to MP4 or WebM — produced on your device, with no watermark.
For cleanup and reframing, the surrounding video utilities — upscaler, stabilizer, compressor, format converter, resizer, canvas extender, rotate, and metadata remover — work in the same place.
- Lifestyle scenes work in motion too.
- Export MP4 / WebM on-device; utilities for upscale, stabilize, compress, and more.
Same concepts as the image editor
The video editor is built on the same shared layer architecture and the same on-device pipeline as the image editor, so the concepts transfer: layers, adjustments, and the no-upload guarantee mean the same thing whether you are working on a photo or a clip. What you learn cutting out a product photo applies directly to a talking-head clip.
