Prompt 1
SEEDANCE · UNIVERSAL PET FIGHTER FORMAT: same duration and aspect ratio as @Video 1 / single-pet replacement / one continuous shot, keep original timing REFERENCES: @Video 1 is the sole source and timeline master. It is uploaded muted. Preserve its exact duration, camera position, camera movement, lens, framing, focus, motion blur, the wet night street, the neon and street-light reflections, the shop shutters, all lighting and color grading. The fighter's performance is the choreography: every stance, weight shift, hop, punch, paw strike, block, head movement, the charge toward the camera and the final strike into the lens, at the exact same moments, speed and direction, frame by frame. Nothing in @Video 1 changes except the fighter's identity. Do not inherit the original cat's identity, fur color, eyes or bandana. @Image 1 defines ONLY the new fighter. It can be a cat or a dog. Preserve this animal's face, eye color, eye condition, fur color, fur pattern, fur length, ear shape, nose, body size and proportions exactly as shown in @Image 1, including any unique features such as a different or cloudy eye, a scar, a missing ear tip or special markings. Keep any collar, bandana or accessory only if visible in @Image 1. Do not inherit the background, floor, furniture or lighting from @Image 1. [optional: short description of your pet, and any unique feature with its exact side, e.g. "black cat, the cat's LEFT eye is cloudy and blind"] VIDEO PROMPT: Replace ONLY the fighter in @Video 1 with the pet from @Image 1. The pet stands upright on its hind legs in the exact same position, scale and framing as the original cat and performs the exact same fight choreography 1:1: same guard stance, same hops and footwork, same punch and paw-strike combinations with the same paw at the same moment, same speed, same power, same head tilts and dodges, same charge toward the camera and the same final strike straight into the lens. The pet keeps its own species, breed, fur length, muzzle shape and body build; if it is larger or smaller than the original cat, keep its body center and floor position identical and scale the body naturally. Any unique facial feature stays on the correct side of the face in every frame, every head turn and especially in the final close-up when the face fills the lens, exactly as in @Image 1, never mirrored. The fur catches the neon and street-light reflections naturally; any accessory moves with the body on every strike. Motion blur on fast strikes matches @Video 1 exactly. Photorealistic, real fur physics, natural animal anatomy, believable upright balance and impact. Camera lock: the camera is a frame-by-frame copy of @Video 1: same position, same height, same movement, same focus changes, same speed and same duration. Do not slow the action down, do not shorten or cut it, do not stop early and do not add camera moves. AUDIO: silent. No music, no sound effects. CONSISTENCY: Exactly one animal. Same pet identity from first frame to last. Unique features and accessories present on the correct side in every frame. Street, lighting, camera and timing identical to @Video 1. NEGATIVE PROMPT: no original cat from @Video 1, no second animal, no human, no identity change, no breed change, no species change, no mirrored face, no eye change, no missing or moved unique features, no added accessories, no fur color drift, no changed punch order, no wrong paw, no slow motion, no slow action, no shortened move, no camera change, no daytime, no dry street, no flicker at the edges of the replaced region, no cartoon, no cheap CGI, no on-screen text, no watermark.

The Knockout
How to put any pet — cat or dog — into a night-street fight clip and have it throw the exact same combo, strike for strike, all the way into the lens.
A TUTORIAL BY DENIZ AKKABAK · @DENIZ.AKKABAK
PIPELINE SEEDANCE 2.5 FORMAT MATCHES THE REEL GENRE PET ACTION CLIP
Nobody can direct a cat through a fight scene. The trick is that you don’t have to direct anything — the fight already happened. Every guard, hop, jab and the final punch into the lens exist inside one eight-second clip. This workflow keeps all of it — the wet street, the neon, the camera, the timing of every strike — and swaps only the fighter. You aren’t describing a combo to the model. You’re handing it the combo and a new face.
THE PIPELINE AT A GLANCE
- 01
Get the reel
Download the reel from Instagram and mute it. This file is your @Video 1 — camera, street and every strike.
- 02
Cast your fighter
One clear photo of your pet. That’s @Image 1.
- 03
Generate
Attach both in order, paste the prompt, match duration and aspect ratio to the reel, render.
STEP 01 — INSTAGRAM
Download the Reel — It Is Your @Video 1
The prompt never lists a single punch. It points at @Video 1 and says copy it, frame by frame. Without the reel attached as a real reference there is no choreography to copy — you’d get a pet standing in the rain, not a pet throwing hands.
Save the reel itself from my Instagram post (@deniz.akkabak) to your phone or computer — the actual video file, not a link and not a screenshot. It goes into the references as @Video 1. Lil Rıfkı is still in it, and that’s exactly right: the prompt keeps every strike and throws away his identity.
@VIDEO 1 — THE REEL, THREE MOMENTS
STEP 02 — AUDIO OFF
Mute It — or Seedance Won’t Render
Reels carry sound, and a copyrighted track in a reference gets the whole generation blocked before a single frame is made — Seedance checks the audio of everything you attach. Strip it before you upload. The punches don’t need to hear anything; they only need to be seen.
AUDIO CHECK — BEFORE YOU UPLOAD
Mute the clip and export a new file. On iPhone: Photos → Edit → tap the speaker icon so it’s crossed out → Done. In CapCut or any editor: mute the clip, export.
Attach the silent file, not the original. Same length, same frames — only the audio track is gone.
Add sound at the end. The render comes out silent — lay your own track or impact sounds back in the edit, or pick a song when you post.
STEP 03 — CASTING
Cast Your Fighter
One photo, one role. Cat or dog, big or small — the prompt keeps your pet’s own body and scales it into the same stance. Pick the photo the way a casting director would: one animal, face toward the camera, both eyes visible, good light, head and chest in frame. The last beat of this clip is a face filling the entire lens, so the face in your photo matters more than anything.
REFERENCE INPUT — THE FIGHTER IN THIS VERSION
NAME ONE-SIDED FEATURES FROM THE PET’S POINT OF VIEW
Lil Rıfkı is blind in his left eye, and a fight clip is nothing but head turns, dodges and a final close-up — the exact moments a model mirrors a face.
If your pet has anything one-sided — an eye, a scar, a folded ear, a patch — fill in the [optional] line with the side as the pet sees it: “the cat’s LEFT eye is cloudy and blind.” Nothing to add? Delete the bracket line.
STEP 04 — SEEDANCE
Generate — One Prompt, Two References
Open Seedance in reference-to-video mode. Attach the two files in exactly this order, set the duration and aspect ratio to match the reel you downloaded, paste the prompt, and render.
REFERENCE INPUTS — ATTACH IN THIS ORDER

SEEDANCE · UNIVERSAL PET FIGHTER
same duration and aspect ratio as @Video 1 / single-pet replacement / one continuous shot, keep original timing
@Video 1 is the sole source and timeline master. It is uploaded muted.

STEP 05
Anatomy — Why It Holds Together
- 01
The contract
FORMAT says “same duration and aspect ratio as @Video 1 / one continuous shot, keep original timing.” The output is locked to the reel before a single pet is mentioned — no reframing, no invented cut.
- 02
The sole source
@Video 1 is “the sole source and timeline master” and “nothing … changes except the fighter’s identity.” The street, the neon, the shutters and the grade are all preserved by one sentence instead of described one by one.
- 03
Choreography by pointing
“Same punch and paw-strike combinations with the same paw at the same moment.” The fight is never written out — naming the paw and the moment is what stops the model from inventing its own combo.
- 04
One job for the photo
@Image 1 “defines ONLY the new fighter,” and “Do not inherit the background, floor, furniture or lighting” keeps your living room from leaking onto a wet street at night.
- 05
Identity marks, sided
“Especially in the final close-up when the face fills the lens … never mirrored.” The last frame is the one everyone screenshots — and the one where a one-sided eye or ear flips first.
- 06
Bodies that fit
“Keeps its own species, breed, fur length, muzzle shape and body build” while “body center and floor position” stay identical — a bulldog or a kitten fights in the same spot without turning into the original cat.
- 07
The camera lock and the insurance
“Do not slow the action down, do not shorten or cut it” fights the model’s habit of softening fast motion. The NEGATIVE list closes the rest: “no changed punch order,” “no wrong paw,” “no daytime,” “no dry street.”
THE RESULT
Output — Lil Rıfkı, Round One
Check yours against the reel, beat by beat: the same paw throws the same strike at the same moment, the hops land on the same frames, the charge reaches the lens at full speed, the street stays wet and neon-lit, and every one-sided feature holds through the final close-up. If something slips, don’t rewrite the prompt — fix the one line that owns it.
EIGHT SECONDS. ONE COMBO. YOUR PET.
The fight was already choreographed. You just pick the fighter.
Swap the street fight for any single-animal clip you love — a dance, a stunt, a dramatic entrance — and swap the photo for whoever runs your house. The skeleton carries all of it: one muted reference that owns the camera, the street and every strike, one image that owns the identity, a sided lock for anything that must not flip, and a camera lock that refuses to slow the punches down.
