What was measured

Output resolution

Does it maintain the input resolution or downscale?

context, not decisivetransformation

Keeping full resolution is important for delivery quality, but it is a downstream output constraint rather than the main background-removal task itself. (3 of 3 judges)

What was given, what came back

Test input: Oregon Coast Walking · video · group: remove-or-replace-video-backgrounds-using-ai

Input — what we sent

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

Output — unretouched

Also checked on this input — same tool, 3 other criteria

Background options◐ MixedThe generated replacement background can include small texture glitches: one desert output showed a dark smeared patch and a stray green dot on the dune ridgeline.Edge quality✓ WorkedIt kept the moving subject’s silhouette clean, with no visible green-screen fringing or halo around the edge.Lighting adaptation⚠ StruggledA requested sunset look was rendered as a warmer color grade on the same midday sun position; the sun disc stayed the same size, brightness, and height in frame instead of moving to a low-horizon lighting setup.

Bria.ai✓ WorkedThe output preserved the source resolution exactly at 2160×3840, with no downscaling.Cutout.Pro⚠ StruggledDownscales the roughly 2160×3840 source to 360×640, so it does not preserve native resolution.Descript✗ FailedIt downscales a 2160×3840 source to a 720×1280 export instead of preserving the original resolution.Fotor✗ FailedA vertical 2160×3840 source was exported into a landscape 2464×1080 canvas, leaving the subject confined to a narrow center strip.VEED◐ MixedDownscales a 2160×3840 source to 1080×1920 on export, cutting the resolution in half while keeping duration nearly unchanged (5.30s→5.27s).
