Generate in 1080P if you want higher-quality Seedance 2.5 outputs.
Use a single reference image only (REFERENCE: [image1] ONLY) and explicitly restrict the video to one adult female model from that image to reduce identity drift.
To keep the face consistent, add an “ABSOLUTE FACE PERSISTENCE / IDENTITY ANCHOR” instruction that locks facial landmarks (eyes/nose/mouth/jaw/face proportions) across all frames and forbids face swap/face morph/identity drift.
Avoid full occlusions and risky transitions: don’t fully turn the head away, don’t fully cover the face with hair/hands/smoke, and avoid strong motion blur, fisheye distortion, heavy flare, deep shadows, or any moment where the face disappears and reappears.
If you need a look-back move, use a safe three-quarter turn that keeps multiple landmarks (cheek/one eye/nose bridge/lips/jaw) visible at all times; avoid full back-of-head and full profile.
Establish identity early by holding a clear close-up of the face for ~1.2s at the start before accelerating style changes.
Change only hair/makeup/accessories/outfit/background while keeping face geometry and body proportions fixed; explicitly forbid age/ethnicity shifts and facial anatomy changes.
When doing rapid style morphs, route the transformation through an external effect (e.g., ink smoke) around the body/clothes and keep a “safe zone” so the effect never crosses the face.
Maintain continuous motion as a single unbroken take (no cuts/teleports/pose resets); each segment should inherit the previous segment’s body pose, gait phase, and camera motion.
Limit occlusion during hand passes: keep face coverage under ~20% and never hide eyes+nose+mouth simultaneously.
To reduce identity drift, don’t stack multiple changes near the face at once—only allow one of {hair, makeup, camera angle} to change at a time while the others stay locked.
Use camera movement that prioritizes face visibility (front to front three-quarter tracking) and avoid extreme wide-angle distortion by keeping sufficient camera distance even at ~28mm.
Specify concrete generation settings like 15s duration, 16:9 aspect ratio, and 24fps to match the intended motion cadence.
