Negative-space gaps between limbs and torso retained a faint warm brown tint instead of pure black, showing residual contamination rather than a clean cutout.
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)

Oregon Coast Walking
A daylight outdoor video of a single person walking along an Oregon coast beach, with the camera following the subject and ocean waves, sand, and sky visible in the background. It was used to test background removal and replacement on a moving subject in a natural outdoor setting.
Why this input is hard
- · Outdoor background removal
- · Subject segmentation during movement
- · Hair and edge preservation
- · AI background replacement quality

Bria.ai⚠ StruggledA strong blue-white halo bleeds past the head and shoulders into the black background, so the silhouette is not clean at the edge.Cutout.Pro⚠ StruggledIntroduces a faint blue-teal halo around the head and shoulders on the cutout.Descript⚠ StruggledThe cutout shows a visible cyan-blue halo around the backlit head and shoulders, so the edge is not a clean silhouette.FlexClip⚠ StruggledUnder harsh backlighting, the beach subject’s torso can read semi-transparent instead of fully opaque, so the matte is visibly incomplete beyond the recurring halo artifact.Fotor✓ WorkedThe moving subject is cut out cleanly across the walk, with the person remaining isolated rather than breaking into jagged edge artifacts.InVideo AI✓ WorkedIt kept the moving subject’s silhouette clean, with no visible green-screen fringing or halo around the edge.Kapwing⚠ StruggledOn the beach silhouette, the cutout edge is soft and fuzzy with a faint greenish fringe around the hood rather than a crisp line.Picsart⚠ StruggledOn the beach clip, backlit sun glare was not cleanly separated and remained as a rainbow-tinted haze over the head and shoulder instead of a clean silhouette.VEED⚠ StruggledLeaves visible haloing and softer torso edges on the cutout, so the silhouette does not resolve cleanly at the boundary.
