Keeps the subject isolated but leaves visible edge artifacts around the hair and shoulders on the talking-head 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)

Indoor Talking Head
An indoor talking-head video of a person speaking directly to the camera with a static background, natural hand gestures, and facial expressions. It was used to test how well tools preserve the subject while replacing an indoor background.
Why this input is hard
- · Static camera performance
- · Face and body segmentation
- · Facial expression preservation
- · Background replacement accuracy in an indoor environment
Output — unretouched
Also checked on this input — same tool, 2 other criteria
Hair and fine detail⚠ StruggledLoses clean hair segmentation and leaves artifacts near the glasses/eye region on the talking-head clip, so fine facial detail is not preserved cleanly.Output resolution◐ MixedDownscales a 4K-class talking-head source from effective 2160×3840 to 1080×1920 on export, while preserving the 15.35s duration exactly.

Bria.ai⚠ StruggledA soft blue-ish fringe remains around the hair and jawline against the black background, indicating visible edge haloing.Cutout.Pro⚠ StruggledCuts the sleeves inconsistently at the frame boundary, so left and right sleeve edges do not line up across timestamps.Descript⚠ StruggledThe shoulder matte is feathered and desaturated compared with the surrounding fabric, leaving a visible rough cutout edge.Fotor✓ WorkedThe subject's outline is matted cleanly, with no obvious tearing or missing chunks around the silhouette.InVideo AI✓ WorkedIt preserved hair and clothing edges cleanly against the replacement set, with no visible halo on close inspection.Kapwing✓ WorkedOn the indoor talking-head clip, the cutout stays crisp with no visible fringing or color halo.Picsart◐ MixedThe indoor talking-head cutout was clean overall, but a faint purple/blue fringe still lingered along the shoulder and collar boundary.
