Prompt formula
Subject + appearance → action → setting → lighting / time-of-day → ONE camera move → style / mood. Put the most important thing first. Direct it like a human — don’t micro-manage the frame.
Language it loves
- Natural, human descriptions over photography jargon
- Exactly ONE clear camera move per shot
- Concrete lighting (golden hour, rim light, volumetric god rays, low-key)
- Film-stock / lens style: “anamorphic, shallow DOF, 35mm grain, teal-orange grade”
- Reference assets named in the prompt: @Image1, @Video1, @Audio1
- Short, abstract sound cues (“rain on leaves”, “distant city hum”)
Avoid
- Stacking conflicting moves (“push-in, then pan, zoom out, orbit”)
- Dense on-screen text or long paragraphs
- Over-detailed per-object foley (can error)
- Durations outside 4/5/6/8/10/12/15

Example prompts — Seedance 2.0
A golden eagle soaring through a misty mountain valley at sunrise, slow dolly-in, golden-hour rim light, anamorphic with shallow depth of field, 35mm grain, cinematic.
She slowly turns to face the camera as wind catches her hair; subtle handheld; soft window key light; quiet ambient room tone.
Smooth transition from day to night — the sky darkens and city lights flicker on; locked-off wide; time-lapse feel.
@Image1 speaks directly to camera in a clean studio, calm and confident, saying @Audio1; soft key light; shallow depth of field.
Tip: in the studio, the agent applies most of this for you — this manual is for when you want to hand-tune a shot.
