Real person segmentation with visible limits
The browser model estimates a foreground mask for a visible person on each frame, enabling transparent or solid-color backgrounds.
Segmentation is probabilistic, not a studio key. Hair, hands, motion blur, chairs, similar colors, partial exits, and fast movement can flicker or disappear.
How to get a cleaner speaker mask
- 1
Choose a suitable clip
Use one well-lit speaker, steady camera, clear contrast, and a short browser-manageable duration.
- 2
Select the background output
Choose transparency when supported or a solid color for a more portable result.
- 3
Watch the full result
Inspect hair, hands, shoulders, chairs, entrances, exits, and gestures.
Designed for simple single-speaker footage

Course introductions
Place a short instructor clip over a branded background.
Product narration
Create a cutout-style presenter layer from a high-contrast source.
Browser segmentation is not a perfect matte
Quality and speed depend on source, device, browser, model support, and encoding.
- Complex rooms, multiple people, transparent objects, loose hair, motion, and low light can break edges.
- Long or high-resolution clips may be slow, heat mobile devices, or exceed memory.
- Transparent video support varies by codec; solid-color replacement is more portable.
Talking-head background questions
Does the video upload for segmentation?
The workspace runs its person-segmentation model in the browser on this device.
Why do hair edges flicker?
Fine strands, motion blur, and similar foreground and background colors make masks uncertain.
Will transparent video work everywhere?
No. Alpha codecs and playback support vary, so test the destination or use a solid-color background.
