Produces rough subject outlines and backpack-edge artifacts on the multi-person street cutout, rather than a clean silhouette.

What was measured

Edge quality

How clean are the cutouts around hair, fingers, and clothing edges; are there visible halo, fringing, or jagged edges?

decisive for this rankingtransformation

Clean edges around hair, fingers, and clothing are a core measure of whether the background cutout works well at all. (3 of 3 judges)

What was given, what came back

Test input: Busy Urban Street · video · group: remove-or-replace-video-backgrounds-using-ai

Input — what we sent

A video of a person walking through a busy city street with multiple people, moving vehicles, and a visually complex urban background. It was used to stress segmentation and tracking under heavy background distraction and continuous motion.

Why this input is hard

· Complex background segmentation
· Handling background distractions
· Subject tracking
· Temporal consistency across frames
· Edge accuracy during continuous movement

Output — unretouched

Hair and fine detail⚠ StruggledRoughly preserves large subject separation but drops fine hood and accessory detail, with imperfect extraction around the fur hood and earphone/scarf region.Output resolution✓ WorkedPreserves 1080×1920 output resolution on export, with the clip staying at 1080×1920 and duration remaining essentially unchanged (20.02s→20.00s).

Bria.ai⚠ StruggledThe cutouts are dim and partially soft-edged, with semi-transparent edge fringing and residue in gaps that should read as pure black.Cutout.Pro⚠ StruggledLeaves a residual dark shadow smudge near the feet instead of a clean shoe-to-ground cutoff.FlexClip⚠ StruggledThe cutout keeps a soft grey-white halo around the beanie and head silhouette, so the edge remains visibly fringed under snowy street conditions.Fotor✓ WorkedFur-hood trim and backpack edges stayed clean, with no hard cutout line around the subject.InVideo AI✓ WorkedIt maintained clean cutout edges in the low-contrast night scene, with no halo or sky-bleed around the silhouette.Media.io⚠ StruggledFor moving multi-person footage, jacket, sleeve, and pant-leg boundaries faded gradually into black instead of cutting sharply, leaving a soft feathered outline.
