When to use it

Taking the background off a picture or a clip to get the subject back alone, ready to composite, layer, or drop onto something else.

When to reach for something else

It keeps what the model finds unless words or a box name one thing to keep, and it redraws nothing. Isolating a subject so it can become a 3D model is Image Isolate’s job: a 3D generator reads a plain backdrop better.

How to use it

1. Use the card’s Image or video area. The picture or clip whose background comes off. The result shows over a checkerboard.
2. Pick a model in the pill at the top of the card, or keep On this device.
3. Press Run.

On the card

Control	What it does	Choices
Image or video	The picture or clip whose background comes off. The result shows over a checkerboard.
Run	Starts the run. The number on it is what this run costs in credits, worked out before you press.
×1	Runs the card several times in a row with the same settings.	1 to 99

Models

The pill at the top of the card picks the model. On this device is the one a new card starts on.

Model	Good for
On this device	Cutting the subject out of a picture onto transparency for free, on the person’s own computer, with the card’s curve, edge and shadow controls shaping the cut.
Bria RMBG 2.0	Cutting the subject out of a picture onto real transparency as a PNG, with nothing to set.
Pixelcut	Cutting the subject of a clip out of its background, keeping fine hair, as a transparent clip.
VEED	Cutting the background out of a clip with no green screen, as a transparent WebM that plays on the canvas or an H.264 RGB plus alpha-matte pair for a video editor.

On this device

Not the one for: Needs a browser with WebGPU; ghosted glass, sheer fabric and motion blur come out cleaner from Bria RMBG 2.0, the other side of the pill.

Behind the settings button:

Setting	What it does	Choices
Hair detail	Rebuilds hair, fur and fine edges from the photo itself, only where the edge is already soft.	On or off
Remove fringe	Takes the old background’s colour out of the edge, so the cutout carries no halo onto its new ground.	0 to 100 %
Clean up	Specks left in the background and pinholes in the subject smaller than this go.	0 to 40 px
Shadow softness	Softens the photo’s own shadow when Shadow is on Keep.	0 to 20 px
Brush size	How wide Paint back and Paint out paint on the picture.	4 to 120 px
Preview on	What the cutout is shown over on the card. The result is transparent whatever this says.	Checker, White, Black
Output	Cutout lands the transparent picture. Mask lands it as black and white: white keeps, black clears. Both lands the two side by side.	Cutout, Mask, Both

Bria RMBG 2.0

Not the one for: Not the step before a 3D generator: those models read a subject on a white studio backdrop more reliably than transparency, which is what image-isolate makes; there is no prompt to say which object to keep.

Behind the settings button:

Setting	What it does	Choices
Hair detail	Rebuilds hair, fur and fine edges from the photo itself, only where the edge is already soft.	On or off
Remove fringe	Takes the old background’s colour out of the edge, so the cutout carries no halo onto its new ground.	0 to 100 %

Output	Cutout lands the transparent picture. Mask lands it as black and white: white keeps, black clears. Both lands the two side by side.	Cutout, Mask, Both

Pixelcut

Not the one for: It is slower than VEED, and like every cloud cut it makes glass and smoke opaque.

Behind the settings button:

Setting	What it does	Choices
Steady	Averages the cut over this many frames where the picture holds still, so an edge does not shimmer. A moving edge is left as the model cut it.	1 to 9 frames
Hair detail	Rebuilds hair, fur and fine edges from the clip itself, only where the edge is already soft.	On or off
Remove fringe	Takes the old background’s colour out of the edge, so the cutout carries no halo onto its new ground.	0 to 100 %
Clean up	Specks left in the background and pinholes in the subject smaller than this go.	0 to 40 px
Brush size	How wide Paint back and Paint out paint on the first frame.	4 to 120 px
Preview on	What the cutout is shown over on the card. The clip is transparent whatever this says.	Checker, White, Black

VEED

Not the one for: Person mode is for real people only, since it ghosts the edges on products and toys; Refine Edges adds a little cost, and the H.264 pair cannot play transparent on the canvas.

Refine edges	VEED’s own pass over the edge, before the card’s. Off costs less.	On or off
Subject is a person	Tells VEED the subject is a person. On a product or a toy it ghosts the edges, so leave it off there.	On or off
