Two record-store clerks. One stray dog with a red bandana. A pizza truck called Slice King. That is the whole cast of SLICE, a two-minute AI short film made end to end on Magnific with Seedance 2.5, and it lands harder than most things ten times its length.
Alejandro Pereira made it. He also kept every prompt, every rewrite and every failure, and he agreed to publish all of it. This is the making of, with nothing cleaned up except the typos. Jump straight to the prompts if that is what you came for.
In this post
The pipeline: which models, in which order
Five tools, one workspace, and a clear job for each of them.
- Seedance 2.0 for the first phase of video. Clips maxed out at 15 seconds, so the story was planned as four 15-second pieces.
- Seedance 2.5 for the final film. It launched mid-production with 30-second generations, and the whole structure was rebuilt around it the same week.
- Seedream for every reference asset: the two protagonists, the pizzaiolo, the dog, the food truck, the loft, the record store, and a bench of secondary characters. All cited later in the video prompts with @references.
- ElevenLabs Music Generation v2 for the original score, and ElevenLabs SFX for specific effects, both inside Magnific.
- DaVinci Resolve for the edit, color, mix and 4K upscale.
Notice what is missing: no stock, no photos, no library assets. Every pixel in the reference set was generated from text first.
A model launch in the middle of production
Seedance 2.5 shipped while Clip 1 was already in progress. Alejandro stopped, threw out the four-clip plan and rewrote the narrative as three 30-second clips, a fourth closing clip, and a four-second title card. Fewer seams, longer takes, more room for the dialogue to breathe.
That last point matters more than it sounds. A 15-second window forces you to compress lines. A 30-second one lets two men walk down a wet Queens sidewalk and argue about a folded Bowie pressing at the pace real people talk. The scene works because it is not in a hurry.
If you have not run Seedance 2.5 yet, it is live on Magnific now.
References before frames
Nothing in SLICE started from a photograph. The characters and sets existed as locked “definitivo” references before the first second of video was generated, built with Seedream in an earlier session, purely from text, iterated until the design held.
When a new set was needed mid-project, the same method: generate the record store interior with no people in it, then cite it as @vinyl store. Style is far easier to nail on a background than on a face, so keep the two problems separate.
IMAGE PROMPT · @vinyl store (Seedream)
Warm Pixar-like stylized realism, interior of a cozy cluttered New York record store, empty of people: wooden counter with a vintage cash register, crates and shelves packed with vinyl records, band posters and album covers on brick walls, a listening station with headphones, warm afternoon sunlight streaming through the front window, dust motes in the light, worn wooden floor, lived-in charming atmosphere, same warm color palette and stylized proportions as a heartwarming animated feature film, 16:9, no people, no text
The prompts, exactly as generated
Five clips, five prompts, all final versions. Read them as a directing document: timestamps every two to three seconds, one camera idea per beat, sound effects called out under every shot, and a hard cut at 29.15 that hands the next clip a locked frame to open on. That handoff is what makes five generations feel like one film.
Clip 1: the street and the food truck

VIDEO PROMPT · SEEDANCE 2.5
CLIP 1 — 30 seconds, 16:9, warm Pixar-like stylized realism. Golden-hour blue-orange New York dusk, wet pavement with neon reflections, parked taxis and manhole steam. Preserve the exact faces, proportions, wardrobe, record-store bags and vinyl sleeves of @Prota 1 and @prota 2 throughout. @Prota 1 speaks with a heavy, funny Queens accent; @prota 2 speaks with a relaxed, marked LA accent. All dialogue is delivered at a natural, unhurried conversational pace, never rushed. Natural voices and location SFX only; absolutely no music. 0-2: Low close tracking shot of their shoes splashing through a shallow puddle; camera dollies backward and rises smoothly. @Prota 1 begins on the very first frame, relaxed pace: “I’m tellin’ ya, that customer folded a first-press Bowie like a taco.” SFX: footsteps, splash, traffic hiss. 2-4: Waist-up two-shot as they walk shoulder to shoulder. @prota 2, unhurried: “Maybe he was hungry for glam rock, dude.” @secondary 1 crosses far behind them wearing headphones. SFX: vinyl sleeves rustling, distant horn. 4-6: Medium profile tracking shot; @Prota 1 clutches his record-store bag protectively: “That album’s older than his emotional maturity.” SFX: crosswalk chirp, soft tire spray. 6-8: Wide frontal tracking shot revealing the lively block; @secondary 2 browses a newsstand on the right without noticing them. @prota 2, grinning: “You did yell ‘vinyl abuse’ in front of a child.” SFX: newsprint flutter, bicycle bell. 8-10: Medium two-shot with a smooth 180-degree orbit from front to side while they continue walking. @Prota 1 shrugs: “Kid needed culture, bro.” Both laugh naturally. @secondary 3 sits on a bench in deep background, chatting silently with @secondary 4. SFX: passing bus rumble, city murmur. 10-13: Wide shot from across the wet sidewalk; the sensibly parked @Foodtruck definitivo Slice King truck appears ahead, tight to the curb on the wide sidewalk, service window facing pedestrians and never obstructing the roadway. Both men notice it while still walking; rack focus from a neon reflection to the Slice King sign. @prota 2 inhales deeply: “Whoa. I can smell carbohydrates achieving enlightenment.” SFX: oven crackle faintly emerging, traffic. 13-15: Low dolly rising into a delighted two-shot as they angle toward the truck. @Prota 1: “C’mon, let’s recharge our souls with some serious pizza.” SFX: quicker footsteps, curbside ambience. 15-17: Side tracking shot as they approach; @prota 2: “My soul wants extra cheese and zero personal growth.” SFX: light laughter, paper napkins fluttering. 17-19: Camera dollies through rising steam toward the service window. Inside, @Sheet pizzero def is perfectly consistent: Italian pizzaiolo, apron, glasses, curled mustache. He flourishes a wooden peel and greets warmly: “Buona sera, my hungry-a music men!” SFX: peel scraping stone, oven fire. 19-21: Medium two-shot from inside the window looking out at the friends. @Prota 1: “Two slices, boss. Big enough to fix retail trauma.” SFX: register button click. 21-23: Close-up on @Sheet pizzero def pressing fingertips dramatically to his chest, very thick Italian accent: “Trauma? I give-a you mozzarella therapy.” SFX: oven pop, apron rustle. 23-25: Over-the-shoulder from @Sheet pizzero def toward the friends. @prota 2: “Can mine come with emotional support pepperoni?” @Sheet pizzero def grins wide. SFX: distant siren, friendly street chatter. 25-27: Smooth lateral slider inside the truck as @Sheet pizzero def spins toward the oven, apron and face remaining exact. He announces: “Stand-a back. The king awakens!” SFX: boots pivoting, fire roar. 27-29: Medium profile shot; @Sheet pizzero def opens the oven and orange light washes across his glasses and mustache. The friends lean forward outside, clearly separate bodies and bags. No dialogue. SFX: oven door groan, crackling fire. Camera becomes completely still by 29.0. 29-30: At 29.15, hard camera cut to a fresh, locked extreme close-up from inside the glowing oven: the peel begins lifting the pizza toward lens, embers behind it. No dialogue. SFX: crisp scrape and fire crackle. End immediately after this new shot begins, with no camera movement, creating a seamless match into Clip 2’s opening oven shot.
Clip 2: the dog shows up
References: @Prota 1, @prota 2, @Foodtruck definitivo, @Sheet pizzero def, @sheetperrodefinitivo, @secondary (various). Note the new prop rule at the top: the bags are now on the ground, because a man holding a plate and a paper bag at the same time is exactly the kind of shot that breaks.
VIDEO PROMPT · SEEDANCE 2.5
Continue from the previous video, exact same color grading, lighting, tone and character consistency. CLIP 2 — 30 seconds, 16:9, warm Pixar-like stylized realism, golden-hour blue-orange New York dusk. Preserve the exact faces, proportions and wardrobe of @Prota 1 and @prota 2 throughout. @Prota 1 speaks with a heavy, funny Queens accent; @prota 2 with a relaxed, marked LA accent. IMPORTANT VOICE RULE: all dialogue at a natural, unhurried conversational pace — never sped up or compressed. Lines may flow continuously across camera cuts; a cut never interrupts or rushes a line. Natural voices and location SFX only; absolutely no music. IMPORTANT PROP RULE: the record-store bags and vinyl sleeves the boys carried are now resting on the sidewalk at their feet, leaning against the truck’s counter base — never under their arms while they hold plates. 0-2: Opens on the exact same locked extreme close-up from inside the glowing oven: the wooden peel lifts the pepperoni pizza toward lens, embers behind. No dialogue. SFX: crisp peel scrape, fire crackle. 2-4.5: Cut to medium shot inside @Foodtruck definitivo: @Sheet pizzero def, perfectly consistent Italian pizzaiolo with apron, glasses, curled mustache, raises the whole pizza close to his face and inhales deeply with an exaggerated grin: “Aaahh, che profumo incredibile!” The boys lean in outside the window, delighted. SFX: oven crackle, deep theatrical sniff. 4.5-7: Cut to a wide shot from outside the truck, facing @Prota 1 and @prota 2 standing right at the service counter: each is ALREADY holding his own paper plate with exactly ONE single pizza slice on it — never a whole pizza, the two plates clearly separate at all times, never touching or merging. Their record-store bags rest at their feet. @prota 2 stares at his slice: “Dude. It’s actually glowing.” SFX: cardboard plate rustle, street ambience. A cyclist walks his bicycle past in the deep background. 7-9.5: Cut to a low ground-level shot: @sheetperrodefinitivo, the skinny stray dog with red bandana, trots out from behind a nearby trash can and comes right up to their feet, sniffing eagerly toward the plates, huge pleading eyes looking up. SFX: soft paw patter, tiny hopeful whine. 9.5-12: Cut to close-up of @prota 2 glancing down; he softens for half a beat, then performs a fake casual shrug and looks away. In deep background a woman with a grocery bag waits at the crosswalk. SFX: city murmur. 12-14.5: Cut to medium shot: @Prota 1 looks down at the dog right beside him and nervously waves one hand downward to shoo it: “Nah, little guy, this ain’t a charity buffet, okay?” SFX: hand whoosh, distant horn. 14.5-17: Cut to ground-level tracking shot: the dog flinches gently, ears drooping, backs away several steps and sits farther down the sidewalk beside a lamppost, still watching them. A pedestrian with headphones and a tote bag passes behind the dog, never interacting. SFX: retreating paw steps, sad little exhale. 17-19.5: Cut to waist-up two-shot at the counter: @prota 2 takes a big bite and mumbles happily: “Mm. Enlightenment confirmed.” @Prota 1 lifts his slice toward his mouth. SFX: crunchy bite, cheese pull. 19.5-22: Cut to close-up on @Prota 1: the slice stops inches from his open mouth, not taking a bite; his eyes drift past it toward the dog. Rack focus from the slice to @sheetperrodefinitivo sitting by the lamppost, thin body curled, enormous wet tender eyes. No dialogue. SFX: low traffic, faint whine. 22-24.5: Cut to close-up on @prota 2, chewing, deadpan: “Dude, don’t look directly into the puppy galaxy. That’s how they get you.” SFX: soft chuckle. 24.5-27: Cut to medium shot: @Prota 1 lowers his slice, Queens bravado collapsing: “Ah, come on… he’s got eyes like my landlord when rent is late.” He walks two steps, kneels, and places his paper plate with his whole untouched slice on the clean sidewalk near the dog. SFX: knee bend, plate set on pavement. 27-29: Cut to ground-level shot: the dog approaches cautiously, tail trembling, and takes a first careful bite; its eyes brighten. @Prota 1, still crouched, whispers: “Don’t tell nobody I’m sweet.” Camera completely still by 29.0. 29-30: At 29.15, hard camera cut to a fresh, locked close-up: @Prota 1’s hand hovering just above the dog’s head, about to give a gentle pat, warm dusk light. No dialogue. SFX: soft dog chewing, city hush. End immediately after this new shot begins, with no camera movement, creating a seamless match into Clip 3’s opening pat shot.
Clip 3: the goodbye
References: @Prota 1, @prota 2, @sheetperrodefinitivo, @Sheet pizzero def, @secondary 10. This is the fourth substantive rewrite. Read the rules block at the top and you can see the scars of the previous three: the all-caps audio rule, the no-waving rule, the handle-less bags.
VIDEO PROMPT · SEEDANCE 2.5
CLIP — 30 seconds, 16:9, warm Pixar-like stylized realism, golden-hour blue-orange New York dusk, wet pavement with neon reflections, matching color grading, lighting and tone of the reference. Preserve the exact faces, proportions and wardrobe of @Prota 1 and @prota 2 throughout. @Prota 1 speaks with a heavy, funny Queens accent; @prota 2 with a relaxed, marked LA accent. @Sheet pizzero def is the Italian pizzaiolo of the Slice King food truck, identical to the reference: apron, glasses, curled mustache. AUDIO RULE — THE MOST IMPORTANT RULE OF THIS PROMPT: this clip contains ZERO music. No score, no melody, no soundtrack, no emotional swell, no ambient music, at no point, especially not in the final seconds. The entire audio track from first frame to last is exclusively: spoken voices, footsteps, city traffic, oven sounds, dog sounds. CRITICAL GESTURE RULE: neither boy EVER waves. No raised hands, no goodbye waves, no hand salutes, at any moment in the entire clip. All farewells are spoken only, or a small nod of the head. Their arms stay down. IMPORTANT PROP RULE: the boys’ record-store bags are brown paper bags WITHOUT handles, with vinyl records sticking out of the top, always carried firmly tucked and pressed under their arms exactly as in the reference — the bags never float, never hang, the carrying arm never lifts, and the act of picking them up is never shown on camera. IMPORTANT VOICE RULE: all dialogue at a natural, unhurried conversational pace — never sped up or compressed. Lines may flow continuously across camera cuts. BACKGROUND RULE: apart from the tagged characters, any other background pedestrians must be distant, small, out-of-focus silhouettes only — never close to camera, never with visible detailed faces. 0-2.5: Opens on a locked close-up: @Prota 1’s hand gently pats the head of @sheetperrodefinitivo, the skinny stray dog with red bandana, twice; the dog leans into the touch, eyes half-closing with happiness while still chewing pizza. @Prota 1, soft: “Yeah, yeah… good taste, buddy.” SFX: soft pats, happy chewing. 2.5-5: Cut to medium shot: @prota 2 stands nearby grinning, holding his paper plate in one hand and his half-eaten slice raised in the other, and says to @Prota 1: “Too late, bro. You’re officially soft now.” SFX: street ambience. 5-7.5: Cut to two-shot: @Prota 1 stands up, mock protest: “I’m not soft. I’m… locally tender.” @prota 2 cracks up and takes another bite of his slice. SFX: warm laughter, crunchy bite, distant horn. 7.5-10: Cut to a wide shot of the food truck: @Sheet pizzero def walks into frame from the left side of the truck carrying a small wooden crate of tomatoes and basil, absorbed in his own routine, humming to himself, and climbs back inside through the side door — never looking at the boys. Meanwhile on the right of frame the boys stay in continuous natural motion: @prota 2 keeps eating his slice while @Prota 1 crouches again to scratch the dog behind the ear, both still chuckling. Far in the deep background, a small out-of-focus silhouette crosses the street. SFX: crate thud, humming, chewing, traffic. 10-12.5: Cut to ground-level close-up of @sheetperrodefinitivo happily devouring the slice on its paper plate, tail wagging. Off-screen, @Prota 1’s voice: “See? Generosity pays, baby.” SFX: happy chewing, tail thumping, paper bag rustle off-screen. 12.5-15.5: Cut to wide shot: @Prota 1 and @prota 2 already have their handle-less brown paper record bags firmly pressed under their arms, exactly as in the reference, and are ALREADY MID-STRIDE walking away from the truck. Without stopping and WITHOUT ANY HAND GESTURE — no wave, both arms staying down and clamped over their bags — @prota 2 simply turns his head over his shoulder and calls out: “Grazie, boss!” Inside, @Sheet pizzero def, who was scrubbing the oven with his back turned, spins around for a quick beat, waves his kitchen towel and shouts warmly with a thick Italian accent: “Ehi! Tomorrow the dog, he eats-a for free!” Then he turns right back to his oven. Only the pizzaiolo waves — the boys never do. SFX: towel flap, warm chuckle, scrubbing resumes. 15.5-17.5: Cut to wide tracking shot: @Prota 1 and @prota 2 walk away down the sidewalk laughing, paper bags pressed under their arms, hands down; in the foreground the dog lifts its head from the empty plate, watching them leave. @Prota 1, walking: “Not a word about this at the store.” SFX: footsteps, city murmur. 17.5-20: Cut to close-up on @sheetperrodefinitivo: it looks at the empty plate, then at the boys walking away; ears perk up, head tilts, a beat of hesitation. No dialogue. SFX: soft city hush, faint paper plate scrape. 20-22.5: Cut to frontal tracking two-shot of the friends walking: @prota 2: “Your secret’s safe. Unless we need marketing.” @Prota 1 laughs: “Vinyl guy saves dog. Sales go up.” @secondary 10 walks past them in the opposite direction with his headphones around his neck, nodding to his own rhythm, never interacting. SFX: shared laughter, footsteps. 22.5-25: Cut to low ground-level shot: the dog’s paws start trotting after them, timid, keeping a few steps of distance, bandana bouncing. Audio here is only: paw patter on wet pavement, distant traffic hum. 25-27: Cut to frontal two-shot: @Prota 1 glances back over his shoulder, notices the dog following, and exchanges a look with @prota 2; both smile slightly, say nothing to the dog, and slow their pace just a little, arms still over their bags. @prota 2 murmurs, amused: “Dude… I think we’re being followed or something.” Audio here is only: soft footsteps, that murmured line, a distant siren far away. 27-29: Cut to a wide locked shot from across the street: the two friends walking down the glowing dusk sidewalk, the little dog trotting a few steps behind them. Camera completely still by 29.0. Audio here is only: continuous city traffic, footsteps, faint dog panting — absolutely no melody of any kind. 29-30: At 29.15, hard camera cut to a fresh, locked ground-level close-up: @sheetperrodefinitivo trotting toward lens, hopeful bright eyes, bandana bouncing, panting happily. Audio here is only: close paw patter, dog panting, city ambience. End on this locked shot with no camera movement. ZERO music in this clip.
Clip 4: the loft, and the payoff
References: @Prota 1, @prota 2, @sheetperrodefinitivo, @loft 1. The clip with the most generation rounds in the whole short, almost all of them spent on the last nine seconds: one continuous camera move that has to keep the boys in frame while the dog takes over the foreground.
VIDEO PROMPT · SEEDANCE 2.5
CLIP — 30 seconds, 16:9, warm Pixar-like stylized realism, matching color grading, tone and character consistency of the reference. Preserve the exact faces, proportions and wardrobe of @Prota 1 and @prota 2 throughout. @Prota 1 speaks with a heavy, funny Queens accent; @prota 2 with a relaxed, marked LA accent. AUDIO RULE — THE MOST IMPORTANT RULE: this clip contains ZERO music. No score, no melody, no soundtrack swell, no ambient music at any point, and ESPECIALLY none in the final ten seconds and the fade to black. The TV in the loft plays only faint sitcom voices and audience laughter — never music. The entire audio track is exclusively: spoken voices, footsteps, city ambience, door sounds, TV chatter, radiator sounds, dog sounds. TV RULE: the show on the TV is a goofy animated slapstick comedy with characters that look NOTHING like the two protagonists — completely different cartoon characters, different colors, different designs. IMPORTANT PROP RULE: the boys’ brown paper record bags have no handles and stay firmly pressed under their arms until they enter the building; the bags never float. IMPORTANT VOICE RULE: all dialogue at a natural, unhurried conversational pace — never sped up or compressed. 0-2: Opens on a locked ground-level close-up: @sheetperrodefinitivo, the skinny stray dog with red bandana, trotting toward lens on the dusk sidewalk, hopeful bright eyes, panting happily. No dialogue. SFX: paw patter, city ambience. 2-4.5: Cut to a wide shot: @Prota 1 and @prota 2 walk up to the stone stoop of their brownstone building and START CLIMBING THE STEPS with their BACKS to the street, clearly ARRIVING home, moving toward the green front door under the warm entrance light. Behind them, the dog stops at the bottom of the stoop and lets out a tiny hopeful whine. In the far background @secondary 9 walks past on the opposite sidewalk, small and unobtrusive. SFX: shoes on stone steps, tiny dog whine, distant traffic. 4.5-7.5: Cut to a medium shot on the stoop: hearing the whine, BOTH boys freeze mid-step and turn their heads back over their shoulders AT THE SAME TIME with genuinely SURPRISED faces — eyebrows up, mouths slightly open — discovering the dog followed them all the way home. A short beat of stunned silence. Then @Prota 1’s surprise melts into mock sternness and he points down at it: “Don’t gimme those eyes. We ain’t a shelter, pal.” SFX: city hush, a soft amused exhale from @prota 2. 7.5-10: Cut to close-up on @prota 2, one step above, still glancing back over his shoulder, deadpan: “Yeah, sorry, dude. Strict no-adorable-roommates policy.” They both face the door again and continue up; keys jingle at the lock. SFX: key jingle, lock click. 10-13: Cut to ground-level close-up of @sheetperrodefinitivo alone on the sidewalk, looking UP toward the door: the door is heard closing off-screen with a soft thud. The dog’s ears droop slowly… but the very tip of its tail gives one tiny, stubborn wag. Hold on its huge eyes. No dialogue. SFX: door thud, wind, a distant siren. 13-15: Cut to a locked wide shot of the stoop from across the street, the small dog sitting alone in the blue dusk, tiny under the streetlight, still looking up at the closed door. Hold the loneliness for a full two seconds. No dialogue. SFX: quiet city ambience only. 15-18: Hard cut to the interior of @loft 1 at night: cozy warm lamps, brick walls, shelves full of vinyl records, a glowing TV, an old radiator hissing softly by the window. @Prota 1 and @prota 2 sprawl on the couch laughing at the TV, which plays a goofy animated slapstick comedy with cartoon characters that look nothing like them; an open Slice King pizza box sits on the coffee table. @prota 2, pointing at the TV: “Dude, that’s literally you.” SFX: TV sitcom voices and audience laughter, real laughter from both, soft radiator hiss. 18-21: Cut to a closer two-shot on the couch: @Prota 1, grinning, throws a piece of popcorn at him: “Please. I’m way more charming.” They keep chuckling, eyes on the TV. SFX: popcorn bounce, warm laughter, faint TV chatter, an occasional gentle radiator clank. 21-30: The final shot, one single continuous movement INSIDE THE SAME ROOM, the boys never leaving the frame: the camera slowly pulls back from the couch and glides low toward the floor, WHILE @Prota 1 and @prota 2 remain visible in the background the entire time, laughing on the couch bathed in TV glow. As the camera settles near floor level, a plush dog bed enters the near foreground: @sheetperrodefinitivo curled up on it, red bandana still on, a leash on a hook above and a food bowl beside it with the name “SLICE” painted on it. Rack focus: the dog becomes tack sharp in the foreground while the boys and the TV glow stay softly BLURRED BUT CLEARLY VISIBLE behind it in the same frame — one continuous cozy room. THE DOG LOOKS COMPLETELY HAPPY: relaxed joyful face, a soft dog-smile, bright warm content eyes, absolutely NOT sad — no droopy ears, no worried brows. Its tail wags slowly against the bed as it watches the two friends with pure love, gives a long contented sigh, settles its head down on its paws still softly smiling, its eyes blink heavier and heavier, and it drifts off to sleep — beginning to SNORE very softly, a tiny cute rhythmic puppy snore. The camera comes to a complete rest on this locked frame: the sleeping, gently snoring dog sharp in the foreground, the two friends laughing softly out of focus behind. Hold 2 seconds, then gentle fade to black WHILE the audio continues underneath all the way into black: the tiny puppy snore, muffled TV chatter, the boys’ soft laughter, the radiator hiss, faint city hum. STRICTLY NO MUSIC, no melody, no piano, no strings, no humming, until the very last frame of black.
Clip 5: the title card
Reference: @sheetperrodefinitivo. Four seconds, one moving element, and a backup plan in DaVinci in case the lettering broke.
VIDEO PROMPT · SEEDANCE 2.5
4-second video, locked static camera, warm Pixar-like stylized realism. STRICT AUDIO RULE: absolutely NO music, no melody, only a soft happy dog pant and a gentle tail thump. Title card scene: on a warm cream background with soft vignette, the word “SLICE” written in large hand-painted vintage pizzeria lettering arranged in a gentle upward arch, warm red letters with a subtle cream outline, matching the retro Slice King food truck sign style. From behind the big letters, @sheetperrodefinitivo, the skinny dog with red bandana, pokes his head out between the letters, smiling blissfully with his tongue slightly out, ears perked; he tilts his head once and his tail tip appears wagging at the side of the letters. The typography stays perfectly still and perfectly spelled “SLICE” at all times; only the dog moves gently. No other text, no music
What put up a fight, and how each one was fixed
Two numbers first. Substantive rewrites, meaning a real change of approach: two for Clip 1, two A/B versions for Clip 2, at least four for Clip 3, several for Clip 4. Actual generations: far more, because every version ran again and again until a take came out clean, with no stray hands, no floating props, no music sneaking in. The score alone went through at least ten attempts. Here is where the time went.
Rushed dialogue
The first pass at Clip 1 packed roughly one line per second. Nobody can speak that fast, so the model sped the voices up to fit. The fix was structural, not cosmetic: fewer lines, more space between them, and an explicit instruction for an unhurried conversational pace. Timestamps are a budget. Spend them on the words.
Identity swaps
Alejandro tested dropping the @ tag on one protagonist to see if the model would carry him over from the previous clip. It did not. The two men swapped faces, wardrobe, accents. Both protagonists keep their @ tags in every prompt, every time. There is no inheritance between generations, only what you cite.
Hallucinated props
The record-store bags kept growing handles, or floating, whenever the prompt showed them being picked up off the ground. Solution: never show that action. In Clip 3 the boys are “ALREADY MID-STRIDE” with bags “ALREADY” under their arms. If a transition is fragile, cut past it and let the audience fill the gap. They always do.
Music that would not leave
Every clip asked for no music. Music arrived anyway, especially in the final seconds, where the model reads an emotional beat and reaches for strings. Two things fixed it together. The instruction escalated from a plain “no music” to an all-caps block flagged as the single most important rule in the prompt. And the last seconds of each clip were deliberately filled with concrete diegetic sound: footsteps, a door closing, a puppy snore. Leave no silence for the model to score.
Spatial continuity on the final shot
An early version of Clip 4 turned the camera around a corner. The boys left the frame, and with them went the feeling that dog and friends were in the same room. The shot was redesigned as one continuous pull-back that never loses sight of the couch, with a rack focus doing the emotional work instead of a cut.
Text on screen
Video models distort lettering. The title card went in with a fallback ready: an empty shape, with “SLICE” added later in DaVinci if the first generation misspelled it. Plan the rescue before you need it.
The tone of the score
The first music pass sounded like a lullaby. Wrong film. The prompt for ElevenLabs Music was rewritten to ask explicitly for an “adult Pixar” tone, no toy instruments, no nursery feel. Ten attempts later it landed.
The detail the model invented on its own
In one loft generation, unprompted, a pizza box appeared on the coffee table reading “Slice King.” A callback to the food truck from Clip 1 that nobody wrote. Alejandro locked it into the next prompt so it would not disappear, and it is in the final film.
That is the working relationship at its best. You direct hard, you specify everything that matters, and you still leave the model room to surprise you. When it does, keep it.
FAQ
How long is the SLICE AI short film?
About two minutes: three 30-second clips, a fourth closing clip, and a 4-second title card, all generated with Seedance 2.5 on Magnific and edited in DaVinci Resolve.
How do you keep characters consistent across Seedance 2.5 clips?
Lock reference images first, cite them with @references in every prompt, and never drop a tag to test whether the model remembers. It does not. Each clip is a new generation.
How do you stop Seedance 2.5 from adding music?
State the rule as the most important one in the prompt, in caps, and fill the final seconds with specific diegetic sound so there is no gap to score. Then add your own music in post.
Can Seedance 2.5 handle dialogue with accents?
Yes. Declare the accent per character and demand a natural, unhurried pace. Leave enough seconds per line or the voices will speed up to fit.
Where can I make an AI short film like this?
On Magnific’s AI video generator, with Seedance 2.5 for video, Seedream for references and ElevenLabs for music and SFX, all in the same workspace.
