One clip, three sets

The same 5-second clip — matted once, composited onto each set, cut together. She never moved.

Before / after

Left: where it was actually shot — a cluttered home office. Right: the same take, dropped onto a broadcast set. Hair edges clean, desk props kept.

Honest verdict

✓ What held

  • Bria matted a busy bookshelf-and-papers background cleanly in ~21s — hair edges intact, no halo.
  • Real alpha (with background_color:'Transparent') → composite onto any backdrop with full control.
  • Commercial-use licensed — safe for client/brand work, unlike scraped matting tools.
  • One matte → unlimited sets. Each new backdrop is one image + one ffmpeg pass.

⚠ What to watch

  • The default output bakes the background black (opaque) — you must pass 'Transparent' to get a keyable alpha matte.
  • Bria keeps connected foreground props (the desk + mug stayed) — a plus here, but frame the source so nothing unwanted touches the subject.
  • Match the lighting — a set whose key-light direction/temperature disagrees with the talent reads as fake. We matched golden-hour rim light to the skyline.
  • temp.bria.ai URLs expire — download + re-host the matte immediately.
