Prompt guides

Prompts that work in the feed.

Seedance 2.5, Wan 3.0 and Higgsfield Genjutsu: what each is good at, how to write for it, and prompts to start from.

Seven rules for the feed

  1. Win the first second

    Open mid-action on the most interesting thing. No establishing shot, no fade in. If the first frame works as a thumbnail, you’re close.

  2. Shoot for the phone

    Vertical 9:16, with the subject in the middle band. Captions and buttons cover the bottom fifth and the right edge, so keep faces and text clear of them.

  3. Short, then loop

    Six to ten seconds is the sweet spot. A clip that ends where it began gets watched twice, and rewatches count.

  4. Build to one payoff

    One idea per clip: a reveal, a twist or a transformation, landing in the last second or two. Cut anything that doesn’t build to it.

  5. Sound is half the hook

    Describe the sound you want. If you’ll post with a trending track, generate with sound off so the track sits clean.

  6. Make it a series

    Reuse the same character image and look across posts. Recognition turns a view into a follow.

  7. Label it, own it

    Turn on the platform’s AI-generated label for realistic clips, and only use references you have the rights to.

Seedance 2.5

The most cinematic motion on GoodGen, the best at keeping a character from your images, and the only model here that edits a clip you shot.

  • Cinematic hooks
  • Recurring characters
  • Spoken lines
  • Edits

  1. Put the hook in the first line

    Seedance weighs the start of the prompt most. Lead with the subject and the action, then the setting, then the style.

  2. Give each reference one job

    @image1 is the face and outfit, @video1 is only the camera move, @audio1 is the beat. A reference without a stated job gets used however the model guesses.

  3. Let images own the look

    Don’t describe what @image1 already shows. Spend your words on action, camera, timing and sound.

  4. Write beats in order, with times

    “0–2 s: the door swings open. 2–5 s: he freezes and stares into the lens. Last second: he goes back to cooking.” Seedance follows a timeline better than a paragraph.

  5. One camera move per beat

    Slow push-in, handheld follow, whip pan or orbit. Three moves stacked in one beat turn to mush.

  6. Tie speech to the speaker

    Quote the line and say who says it: She leans in and whispers, “don’t tell anyone.” Lines under ten words lip-sync cleanest.

  7. Edits: say only what changes

    Add your clip, switch on Edit and write “Make it snow. Keep the people, camera and timing as they are.” The clip keeps its length and framing.

  8. Know what gets refused

    Real celebrities, brand logos and outfits, and recognizable characters trip the model’s checks. A refused run refunds every credit.

Prompts to start from

POV hook

Seedance 2.5 · 9:16 · 720p · 6 s · Sound

POV: you open the fridge at 3 a.m. and a tiny chef is cooking in the butter tray. Phone-camera look, warm fridge light. 0–1 s: the door swings open on the chef mid-flip. 1–4 s: he freezes and stares into the lens. Last second: he shrugs and keeps cooking. Sizzle and fridge hum, no music.

Product drop

Seedance 2.5 · 9:16 · 1080p · 6 s · Sound

A matte black sneaker drops into frame and lands on wet asphalt at night, water splashing in slow motion, neon reflections everywhere. Low camera, slow push-in. Last second: the sneaker starts to spin on its own. A deep bass hit on the landing, rain ambience.

Your character, new scene

Seedance 2.5 · 9:16 · 720p · 8 s · Sound

@image1 is the character. She walks toward the camera through a crowded night market, steam and lanterns around her, stops, looks into the lens and smiles. Handheld follow, shallow depth of field. Market chatter and sizzling woks.

Add your character image, then generate.

One-line skit

Seedance 2.5 · 9:16 · 720p · 6 s · Sound

Close-up of an old man at a bus stop who turns to the camera and says, deadpan, “I’ve been waiting since 1987.” A bus drives past behind him without stopping. Overcast daylight, documentary handheld. Traffic noise.

Wan 3.0

Wan 3.0 Prime: the lowest price per second on GoodGen, clips from 2 seconds, and exact start, end and loop frames. Built for testing a lot of hooks fast.

  • Cheap hook tests
  • Seamless loops
  • Before and after
  • Short memes

  1. Draft at 480p, ship at 1080p

    480p costs about a quarter of 1080p. Find the hook that works, then run the winner again at full resolution.

  2. Use the formula

    Subject, scene, motion, then camera, light and style: “A golden retriever on a kitchen floor slowly tilts its head. Close-up, soft window light.”

  3. Enhance ideas, not finished prompts

    Wan rewrites your prompt with its own language model while Enhance is on. Keep it on for a one-line idea; switch it off once you’ve tuned every word.

  4. Loop from one image

    Add one image and choose Loop. Wan starts and ends on that exact frame, so the clip repeats with no seam. Ask for small motion only: steam, hair, rain, a blink.

  5. Before and after in one clip

    Add two images and choose Start and end. Wan animates from the first to the second: messy to clean, day to night, sketch to finished.

  6. Go short

    Wan renders from 2 seconds. A 3-second reaction or a 4-second gag is the cheapest way to post every day.

  7. Describe the sound

    Wan makes sound with the picture. Name it, “rain on a tin roof, distant thunder”, and quote any spoken line.

  8. Mind the limits

    Reference clips run 1–15 seconds, 15 in total, and the video plus its reference clips stays within 30 seconds. Frames can’t be mixed with other references. For edits or 21:9, use Seedance 2.5.

Prompts to start from

Head tilt

Wan 3.0 Prime · 9:16 · 480p · 3 s · Sound

Close-up of a golden retriever on a kitchen floor slowly tilting its head, ears lifting, as if it just heard its name. Soft window light, shallow depth of field. A quiet, curious whine.

Seamless loop

Wan 3.0 Prime · 9:16 · 1080p · 6 s · Sound · Enhance off

Steam curls up from the coffee, the cat’s tail flicks once and rain runs down the window. Nothing else moves. Static camera. Soft rain and a ticking clock.

Add one image, then choose Loop.

Before and after

Wan 3.0 Prime · 9:16 · 720p · 8 s · Sound · Enhance off

The messy desk tidies itself in one smooth time-lapse: papers stack, cables coil, the mug slides to the corner. Static top-down camera. Soft clicks and paper rustles.

Add the before image, then the after, and choose Start and end.

Street interview

Wan 3.0 Prime · 9:16 · 720p · 6 s · Sound · Enhance off

Handheld street-interview shot on a busy crossing in Tokyo. A woman in a yellow raincoat laughs into the microphone and says, “Honestly? Best day of my life.” Natural daylight, city noise, a light lens flare.

Higgsfield · on GoodGen

Higgsfield Genjutsu

Higgsfield’s Genjutsu remakes a clip that already works: keep a video’s motion, camera and timing, and swap who or what is in it. Add the source clip and the images, pick the mode, and say what changes.

  • Trend remakes
  • Character swaps
  • Product swaps
  • New sets

  1. Pick the mode first

    Motion Transfer keeps only the movement, camera and timing and rebuilds everything else from your references. Object Swap changes one thing (a character, outfit, product or place) and leaves the rest of the shot alone.

  2. Start from a clip that already holds attention

    Your own footage of a trend, a dance or a reaction, 4 to 30 seconds. One continuous shot with steady framing and the whole subject in view transfers best. Hard cuts and fast zooms don’t.

  3. Frame the source for the feed

    The result follows your source clip, so shoot or crop it 9:16 before you upload it.

  4. Clean references win

    Well-lit, front-facing images in the same pose and framing as the subject in the clip. Full body if the clip is full body. A plain background helps.

  5. Say what changes, then what stays

    “Replace the dancer with the woman in the image. Keep the choreography, camera and timing.” One change per run.

  6. Draft on Lite

    Switch on Lite for drafts: faster and much cheaper, for source clips up to 15 seconds. Find the version that works, then run the final at full quality.

  7. Priced by the clip

    A Genjutsu run costs what its source clip does: its length and the resolution set the price, which you see before you generate. Trim the clip to the part that matters.

  8. Rights and consent

    Use source clips you shot or have the rights to, and never put a real person’s face or body into a clip without their consent.
