I rebuilt a viral Youtube Short with AI — it got 522K views

Complex action is no longer the hard part. AI can reproduce it now. What it still can't do for you is direct — and that is the actual skill: shot sizes, camera moves, where the cut lands, and what you deliberately keep out of frame.

I rebuilt a 321-million-view Korean Short to test that. First attempt: 522,000 views. The result is 42 seconds: three 15-second generations cut together.

Most AI video falls apart for a boring reason — it cuts too much. Every second and a half the model hands you a new angle, and the result reads as a slideshow of unrelated frames. The clip I was rebuilding does the opposite: four camera setups inside the first four seconds, then 27 seconds without a cut. That contrast is the whole trick.

Here is the full process, including the three prompt sets that produced the result.

TL;DR — four cuts inside four seconds, then 27 seconds of continuous slow motion. One reference image, reused by all three clips. Three 15-second prompts, every beat timecoded to a camera and a single event. Expect several takes per prompt: the density is why one pass rarely lands.


The two clips

The original — 32 seconds, 321 million views. A Korean Short where a couple keeps a falling egg in the air. The uploader blocks off-site playback, so here is the cover — click through to watch:

The reference Short: a pastel kitchen, a woman with a purple braid carrying a tray of eggs, a man at the table

My rebuild — 42 seconds, 522,000 views. Three 15-second Seedance 2.5 clips, same kitchen, same beat structure, plus a dog:

One case, not a formula: the same prompts will not reproduce it, and they did not reproduce the original's numbers either. What is reproducible is the order of work:

  1. Tear the reference down frame by frame — write a shot list before you write a prompt.
  2. Build exactly one reference image — the whole Short runs on it.
  3. Write timed prompts — three 15-second clips, each beat given a timecode, a camera, an action.
  4. Generate several takes per prompt — the action is too dense for one clean pass.
  5. Cut in the timeline — sound effects are requested in the prompt; music and captions are not.

That order is the point. Everything below is detail.


1. The shot list comes first

Before any prompt, the reference is broken into beats down to the frame. Nearly every instruction later in this post comes from this table.

Timecode What happens Camera
0s00f–1s10f She cuts a snack; an egg rolls toward the table edge Eye-level medium
1s10f–2s00f The egg leaves the table Side view
2s00f–2s26f Egg falling; her astonished face Low angle from the floor, looking up
2s26f–4s08f The egg keeps falling Top-down
4s08f–8s11f He throws a whole tray of eggs into the air and dives after the falling one Wide, tracking the dive
8s11f–11s06f He lands flat; his right hand catches the egg and bounces it skyward Low, on the floor
11s06f–12s08f The egg rising Locked on the egg
12s08f–13s26f She reacts — mouth open — and dives after it Medium
13s26f–16s05f She moves under the egg and jumps, both arms up Wide
16s05f–17s19f Second save: she pushes it back up Medium
17s19f–19s22f Two levels: her jumping, him climbing from chair to table Wide + near
19s22f–20s22f Her face, close, eyes wide Close-up
20s22f–22s22f He hits the egg forward Medium
22s22f–23s26f She grabs a frying pan Medium
23s26f–25s03f Side view of the same hit Side
25s03f–26s03f She slides on her knees, pan held up Follow
26s03f–28s03f Top-down on the pan, push in to a close-up Top-down → macro
28s03f–31s17f The egg lands in the pan; thumbs-up Medium

Two things fall out of this table immediately:

  • The first four seconds are four different setups. That's what makes the egg's fall feel chaotic.
  • The next twenty-seven seconds never cut away from the action. Slow motion is what keeps a single continuous shot readable when that much happens inside it.

If you take one thing from this post: write the shot list first. A prompt written without a shot list produces exactly the slideshow you were trying to avoid.


2. One reference image, not three

This is where the workflow differs from the usual prompt list: three prompt sets, one image.

Left: the single kitchen reference image. Right: a frame from the finished Short — same room, same two people, same pastel palette.

Left: the reference image, built once and reused by all three clips. Right: a frame from the output. The composition, the characters and the palette all come from that one still.

The kitchen is built once — 9:16, the woman with purple braids on the left holding a tray, the man at the table on the right drinking water, one egg at the table edge between them — and every clip references that same image.

Two decisions worth copying:

Both characters are in frame from the start. Every clip needs her, him and the egg, so the reference has to establish all three at once. The cost is that each prompt then has to work to keep the wrong character out of individual shots (more on that below).

The iterations went into the egg and the poses, not the room. A reference image is cheap to fix and expensive to re-shoot. Fix it before you spend a single credit on video.

If you build your own, keep the shape: one room, two people, one small object that is going to fly.


3. The three prompt sets

Each set is a 15-second clip. The first line of every set names who is who, because one image carries both characters. Every beat has a timecode.

Set 1 — the egg rolls off the table

She is the purple-braid woman, he is the black-haired man.

[0-2s] Reference.

The black-haired man sits on the chair drinking water; the
woman carries a tray of eggs and is slowly walking toward the
counter top in front of her; the camera focuses on the single
egg on the dining table, which is rolling toward the table
edge and has just dropped off the table.

[3-5s] The instant the egg rolls off the table and drops, the
picture enters slow motion: a low-angle close-up from the
floor shows the egg falling through mid-air in slow motion.
While the low-angle close-up holds on the egg, the
black-haired man must watch the egg's slow-motion fall in
extreme panic.

[6-9s] The purple-braid woman looks toward the front of the
camera in extreme anxiety and panic; she throws the plate in
her hands and the eggs on it hard into the air behind her. The
picture enters slow motion; the eggs scatter in mid-air behind
the woman; the purple-braid woman dives forward toward the
front of the camera in slow motion, anxious and terrified.

[10-12s] Slow motion, shot from a ground-level point of view.
A slow-motion shot of the purple-braid woman: she lies on the
floor and slides toward the camera; in the background some
out-of-focus eggs are falling in slow motion and smashing on
the floor behind her. She looks up in utter terror at one egg
in the upper foreground that is falling toward the ground, and
she reaches one hand out along the floor, palm up, trying to
catch the egg falling from the air.

[13-15s] Slow motion. The egg drops into the woman's hand; she
pushes upward hard but does not hold it — the egg is pushed
high and flies up out of frame above the camera. The woman
must keep watching the egg in utter terror, and only this one
egg may appear in the picture.

Set 2 — the man's run and the first volley

This is where the negative constraints do the heaviest work: three beats in a row end with the woman must not appear in the picture, because the single reference image contains her.

She is the purple-braid woman, he is the black-haired man.

[0-1s] Reference.

Close-up of the man's chest and head. In extreme panic his
gaze moves slowly in slow motion from the upper right to the
upper left, and as he looks he slowly spits the water in his
mouth out in slow motion. The woman must not appear in the
picture.

[4-7s] Slow-motion shot of the man's upper body. Side-on to
the camera, he takes two quick steps toward the edge of the
frame, turning his head as he runs to look up above the camera
in extreme panic, then he jumps hard in slow motion with both
hands raised in a lifting motion. The woman must not appear in
the picture.

[8-11s] Slow motion, close-up of the man as he jumps in
mid-air in slow motion with both hands raised in a lifting
motion. An egg is flying from the air toward the man's hands;
he pushes up hard but does not catch the egg and sends it high
up, out of frame above the picture. The woman must not appear
in the picture.

[12-15s] Slow motion. In the background the man makes the
lifting motion, watching an egg above him in anxious panic as
it slowly flies up into the air. Side shot of the woman: in
the foreground she stands on the chair, looking toward the egg
in the sky with her back to the camera, knees bent and loading
to jump. There is no egg on the table at this moment.

Set 3 — the spike, the bowl and the face

The busiest set. She spikes the egg downward like a volleyball, he slides in on his knees with a bowl, and the clip ends on a gag instead of a clean catch.

She is the purple-braid woman, he is the black-haired man.

[0-2s] Reference [].

Slow motion, low-angle shot. In extreme anxiety and panic the
woman stands on the dining chair that the man sits on in the
reference image, looking up above the camera; she loads and
jumps high, reaching out one hand in the pose of a volleyball
spike. The black-haired man must not be in this shot.

[3-5s] Slow motion, shot of the black-haired man. In the
corner of the reference image, in utter anxious panic, he
looks up above the camera and runs toward the camera, pulling
a big bowl out from behind him at the same time, running in
slow motion toward the camera and out at the edge of the
picture, anxious.

[6-8s] Slow motion, side shot of the woman in mid-air in a
spike pose, her face full of anxious panic. An egg is flying
slowly from above her shoulder toward the front of her hand;
with one slow-motion spike she hits the egg and sends it
flying down and out of the picture at a diagonal. The egg must
not be broken by her hit.

[9-10s] Slow motion, high-angle follow shot of the
black-haired man sliding toward the camera on his knees, his
weight leaning back, holding a big bowl in both hands with the
bowl facing up in front of him, ready to catch something.

[11-12s] Over-the-shoulder view of the man, slow motion. His
weight leans back as he slides toward the woman on his knees,
holding the big bowl in both hands in front of his chest ready
to catch the egg; the woman is falling from mid-air in utter
terror watching the egg; an egg is flying slowly through the
air toward the man.

[13-15s] Slow motion, slightly high-angle follow shot of the
man sliding on the floor toward the camera, his weight leaning
back, his expression going slowly from anxious panic to happy,
looking up above the camera, holding the big bowl in both
hands in front of his chest as if he wants to catch something.
The slow motion ends: a raw egg smashes hard onto the
black-haired man's face, the egg breaks and the yolk and white
cover his face; the man freezes for a moment, then a close-up
of his face as he breaks down and screams.

4. What I learned about prompting complex action

These six rules are the transferable part. They apply to any multi-shot AI video, not just this kitchen:

1. One reference image for all three clips. Every set opens by naming who is who, and reuses the same image instead of rebuilding one per shot.

2. Every beat names its camera. Low angle, side, top-down, over-the-shoulder, follow — plus shot size and movement. The prompts read like a shot list, not a mood description.

3. Slow motion is stated in almost every beat. With this much action in 15 seconds, slow motion is what makes it legible. It is the one stylistic instruction that never gets left implicit.

4. Negative constraints replace missing references. Because one image holds both characters, shots that need only one of them say so explicitly: the woman must not appear in the picture, only this one egg may appear in the picture. If you've ever written JSON Schema or regex, this is the same idea: constrain what must not occur, don't hope the model infers it.

5. Beats are 2–4 seconds and exactly one event. Camera, action, expression, and what the object does. Nothing else.

6. The same closing line every time. Rich sound effects, no background music, no subtitles — leaving the edit to the edit.

And the unwritten rule that matters most: plan for several takes. The action is too dense for one clean pass. Generate multiple, keep the best beat from each, cut them together. Expecting a single prompt to land is the most common way this fails.


5. Things that will trip you up

The source was a working note, not a tutorial, and a few details don't line up:

  • The prompts don't end like the reference. The teardown ends with the egg landing in a frying pan and a thumbs-up; set 3 ends with a raw egg on his face and a scream. It's a comedy remix, not a frame-accurate copy — decide your ending and write it into the last beat.
  • The pan becomes a bowl. Use one word in both places or the prop will drift between clips.
  • Set 3 opens with an empty reference slot (Reference []). All three clips start from the same kitchen image — fill it.
  • Set 1 fights itself. [6-9s] throws a whole tray of eggs into the air, while [13-15s] says only one egg may appear. Keep the scattered eggs out of focus in the background and apply the rule to the foreground.
  • Timecodes restart in every set. [0-2s] in set 1 and in set 3 are different clips. Generate each as its own 15-second clip.

6. Adding the dog

The version that took off added a dog to make the scene more complex. My working document records the change and the view count but not the rewritten prompts, so that pass was written by hand.

The rule that made it work is the same one the two characters already follow: put the dog into the reference image first, then name it in every beat and give it one job in the rally — going for the egg. A dog that only sits in the background does not survive a 15-second shot.


Closing

The three prompt sets were generated in aiMakeVideo with Seedance 2.5, image-to-video, 9:16, 15 seconds per clip. The shot list is my own teardown of the reference Short.

If you want the parameter side of this — what each clip costs in credits, how 480p and 720p compare — that's collected in this open-source companion repo.

The transferable part isn't the egg. It's the order: shot list → one reference image → timed beats → multiple takes → cut in the timeline.
