Does it work on objects or pets, or only people?

For video, Background Eraser detects people — it is built for talking-head videos, presentations and tutorials. For photos, the cutout detects the main subjects of the picture, and you choose which detected subjects to keep.

What formats can I export?

Videos export as MP4 (H.264) at full, 1080p, 720p or 540p resolution, with canvas presets for vertical 9:16, square 1:1, 16:9 and other social formats. Photo cutouts export as PNG, including transparent PNG.

Edges that hold up in motion

Auto-segmentation gets you 95% of the way; edge refinement covers the last 5% that separates a clean composite from an obvious cutout. Background Eraser gives you four GPU-accelerated controls — feather, smoothing, tightness, and temporal smoothing across frames — with the result previewed live.

Feather

0–20 px

Softens the cutout edge so you blend naturally into the new background instead of looking pasted on.

Smoothing

0–15 px

Cleans up speckles and jagged spots in the mask — stray pixels around hair and clothing disappear.

Tightness

−15 to +15 px

Expands or chokes the entire cutout. Pull it in to remove background halos; push it out if edges clip into you.

Temporal smoothing

on/off strength

Blends the mask across frames so edges stay stable in motion instead of shimmering frame to frame — the difference between amateur and clean.

Video is harder than photos: an edge that flickers between frames is more noticeable than an edge that's slightly soft. That's why temporal smoothing exists — it evaluates the mask across time, not just per frame, which most online removers skip entirely.
