Transparent cut-outs
An isolated subject on a transparent background, for motion-graphics shots and layouts. Generate it with transparency rather than removing a background later [official guidance].
An isolated subject on a transparent background, for motion-graphics shots and layouts. Generate it with transparency rather than removing a background later [official guidance].
Set the background to transparent.
Keep geometry, edges and any label exactly; no added shadow, backdrop or reflection.
A photoreal subject uses GPT Image's Sunburst model, for precision (on 2.6 the standard model; on 2.5 the Sunburst variant; see Still prompts, storyboard frames and diagrams → GPT Image's two jobs and its version rule). Exact label text follows the product rules: the client's artwork carries exact copy (see Photoreal anchors (Nano Banana Pro) → Products and labels). The client's product is always pristine (decided).
A stylised subject uses GPT Image's Flare model, never Seedream, with the approved stylised asset (a prop sheet or the style anchor, see Stylised films (Seedream 5.0 Pro) → Stylised plates and props) attached as Image 1, owning the design and the drawing style. Check the result beside it at full size for line weight, shading and colour.
Check the edge at full size against a dark and a light background, for halos, fringes and lost fine detail (steps below).
Template (written for this guide)
A transparent cut-out of {subject} for {use}, {view}, {aspect}.
INPUTS: {Image 1 owns {shape, colour, label / the design and drawing style} only.}
SUBJECT: {material, colour, details, state}.
LOCKS: background fully transparent; no shadow, no backdrop, no reflection; edges clean; {label exactly as Image 1 / no text}.
Example: photoreal, for an end card (written for this guide)
A transparent cut-out of half a pomegranate for a motion-graphics end card, the cut face toward the camera, tilted slightly up, 1:1.
SUBJECT: a fresh pomegranate cut cleanly in half, a leathery red-brown rind with small natural blemishes, pale yellow membranes dividing tight clusters of glossy deep-red seeds, a bright highlight on a few seeds, one bead of juice at the lower edge of the cut.
LOCKS: background fully transparent; no shadow, no backdrop, no reflection; edges clean; no text.
Do it yourself
Check a cut-out's edge (Photoshop, Affinity or any editor with layers)
Put the cut-out over a black fill layer.
Look at 100% for halos, fringes and lost fine detail.
Change the fill layer to white, and look again at 100%.
