Ten-second Roblox speedrun that ends with doing it all again

F*CKING GENIUS...

this guy took the classic "what if" concept and turned it into 2D Roblox animations.

his VERY FIRST video pulled 1.3M views, and he already monetized the entire channel.

so I recreated the exact format using Claude Opus, entirely with code, for $0.

and I'm dropping the full prompt for FREE.

barely anyone is doing this format right now.

thank me later for this 👇

<ROLE>

You are my AI animation studio, Roblox animation director, scriptwriter, character designer, motion graphics engineer, and video production specialist.

Your job is to create high-quality, fully animated Roblox-style YouTube Shorts similar in production style, pacing, storytelling, and visual polish to my attached reference video.

I want real character animation, not AI-generated still images with basic zoom effects.

You will handle the entire production workflow using Claude Code, Python, JavaScript, HTML Canvas, SVG, FFmpeg, and any necessary image and audio tools.

Your goal: Create an original, entertaining 45–55 second Roblox animated Short that feels like a professionally edited cartoon.

The reference is for understanding animation techniques, not for copying its characters, footage, dialogue, or exact storyline.

Before generating assets, show me the script, storyboard, and production plan.

Before rendering the final video, show me an animated preview and wait for approval.

<STEP 1 — ANALYZE MY REFERENCE VIDEO>

First, inspect the MP4 file I attached.

Use FFprobe to identify:

Resolution

Frame rate
Duration
Audio streams
Video encoding
Extract frames at regular intervals, plus additional frames around major scene changes.

Create a contact sheet showing the entire video.

Analyze:

Character design

Background illustration style
Facial expressions
Character movement
Scene composition
Camera movements
Transitions
Subtitle placement
Subtitle animation
Color grading
Gaming HUD elements
Storytelling rhythm
Average scene duration
Sound effects and narration timing
If speech transcription is available, transcribe the narration and estimate the words spoken per minute.

Do not assume the narration from the subtitles alone.

REFERENCE CHARACTERISTICS

The reference runs approximately 50 seconds at 1080×1920 and 60 FPS.

It features:

2D blocky Roblox-inspired cartoon characters

Clean dark outlines around characters and objects
Simple geometric bodies
Large square or rounded-square heads
Exaggerated expressions
Bright, saturated colors
Stylized Roblox game worlds
Cartoon bedroom environments
Oversized virtual-game interfaces
A persistent countdown timer
Dramatic close-ups
Comedic reactions
Fast-paced editing
Animated word-by-word captions
The storytelling alternates between a real-world family situation and increasingly ridiculous events inside a virtual Roblox-style world.

The narrative uses a countdown to create urgency, then escalates through rewards, power-ups, transformations, characters reacting, and an unexpected ending.

Identify the specific techniques that make these sequences engaging.

Recreate those techniques using original assets.

<STEP 2 — ASK ME FOR MY STORY>

Before production, ask me:

1. What should the video be about?

Examples:

What If Dad Deleted Your Roblox Account?

What If You Had Unlimited Robux for 10 Seconds?

What If Every Roblox Game Combined Into One?
What If You Became the Richest Noob?
What If Your Roblox Character Could Talk?
What If You Had One Minute to Escape Roblox?
If I don't have a topic, suggest five original story ideas with strong hooks.
2. Which voice generation tool should we use?

Options:

ElevenLabs

Kokoro

Other available text-to-speech service
3. Which asset generation tools are available?
Options:

GPT Image

Another reference-capable image model

Fully programmatic SVG/vector illustration
Prefer code-generated reusable vector assets for elements requiring consistent animation.
Only use image generation for assets that cannot be efficiently illustrated in code.

Do not begin production until I approve the concept.

<STEP 3 — SCRIPT STRUCTURE>

Write an original 45–55 second script.

Target approximately 135–165 words, adjusted to the chosen narrator's natural speaking speed.

The storytelling must feel fast, funny, and unpredictable.

Use short sentences.

Make every sentence introduce an action, joke, reveal, or consequence.

Avoid lengthy explanations.

STORY FORMULA

0–3 seconds — THE HOOK

Open with an absurd Roblox-related situation.

Example:

"What if your dad gave you just TEN seconds to become the richest player in Roblox?"

Show the situation immediately.

No intro sequence.

No logos.

No slow setup.

3–8 seconds — THE RULES

Introduce the challenge or restriction.

Show the protagonist reacting.

Use an animated timer, warning, or game mechanic to create urgency.

8–15 seconds — THE FIRST WIN

The main character starts making progress.

Show an entertaining action sequence.

Introduce the first reward, achievement, or surprise.

15–24 seconds — ESCALATION

Increase the stakes.

Add something visually ridiculous:

Massive rewards

A difficult obstacle course

A giant enemy

A strange transformation
An unexpected purchase
A character gaining an absurd ability
Each new event should be more surprising than the previous one.
24–33 seconds — THE TWIST
Introduce an unexpected problem.

The protagonist's advantage creates a new challenge.

Use exaggerated character reactions.

33–43 seconds — COUNTDOWN AND PANIC

Increase the urgency.

Show the character trying to solve the problem.

Use faster cuts, close-ups, ticking sounds, and a changing timer.

43–50 seconds — COMEDIC PAYOFF

Deliver an unexpected outcome that connects to the opening situation.

50–55 seconds — LOOPABLE ENDING

End with a funny final line, cliffhanger, or question.

Where possible, make the last scene visually connect to the beginning so the Short loops naturally.

SCRIPT REQUIREMENTS

Every line must be visually actionable.

Do not write narration that cannot be shown through animation.

The protagonist should have a clear objective.

The story needs at least one surprise and one comedic payoff.

Do not invent real Roblox game features and present them as verified facts. Fictional powers and game mechanics are allowed when clearly part of the story.

Provide the complete script for approval.

<STEP 4 — VISUAL STYLE>

VIDEO SETTINGS

Resolution: 1080×1920

Aspect ratio: 9:16

Frame rate: 60 FPS

Format: MP4

Target duration: 45–55 seconds

ART DIRECTION

Create an original Roblox-inspired 2D cartoon universe.

The visual language should resemble animated Roblox story Shorts rather than actual recorded Roblox gameplay.

Use:

Blocky geometric bodies

Square and rounded-square heads

Large expressive eyes

Thick clean character outlines

Flat colors with simple highlights
Soft shadows
Colorful cartoon environments
Stylized lighting
Recognizable game-inspired objects
Oversized reaction expressions
Characters should look like designed cartoon avatars, not realistic humans.
Avoid photorealistic renders, generic 3D avatars, anime proportions, or unrelated illustration styles.

The characters must be expressive.

Create reusable facial expressions:

Neutral

Smiling

Excited

Surprised

Angry

Sad

Crying
Terrified
Confused
Smug
Screaming
Laughing
EYES
Animate blinking approximately every 2.5–4 seconds with slight timing variation.
Allow eyes to widen during surprises.
Use eye position changes to communicate attention.
EYEBROWS
Animate eyebrow positions independently.

Angry expressions should use inward-sloping eyebrows.

Surprised expressions should raise the brows.

Worried expressions should use asymmetric curves.

MOUTH

Create reusable mouth shapes for speech animation.

At minimum, include:

Closed

Small open

Wide open

Rounded

Smile

Frown

Avoid repetitive animation loops when the scene calls for a specific action.

<STEP 8 — BACKGROUNDS>
Create reusable environments inspired by the reference's composition and production quality.
A. BEDROOM
A cartoon bedroom at night.

Include:

Bed with colorful blanket

Bedside table

Lamp

Window

Curtains

Posters

Door

Rug

Warm hallway lighting
Build the room with separate layers.
Characters should be able to stand in front of the bed, move through the doorway, and interact with objects.
B. ROBLOX-INSPIRED OBBY WORLD
Create a colorful obstacle-course environment.
Include:
Floating platforms
Checkpoints
Lava

Clouds

Finish-line signs

Bright geometric obstacles

Stage markers

Allow the avatar to jump across platforms.

Use background depth and perspective to create a sense of scale.
C. GAME SHOP
Create a stylized game-store interface with:
Item panels
Currency counter
Buy buttons
Upgrade icons

Inventory tiles

Progress indicators

The UI should be readable on a phone screen.

D. CARTOON GAME WORLD

Create a larger environment containing:
Grass platforms
Blocky trees
Paths
Decorative buildings
Other avatars

Floating rewards

Particle effects

Design additional environments according to the approved script.

Do not create unnecessary locations just to match the reference shot for shot.
<STEP 9 — GAME INTERFACE DESIGN>
Game-like UI is an important part of the reference.
Create reusable animated interface components.
COUNTDOWN TIMER
Place a rounded dark timer panel near the top center.
Include a stopwatch icon.

Display the relevant time remaining.

At normal time:

Dark background, white text.

At critical time:

Red background, white text.

The timer should animate when the story calls for it.

Treat the timer as a fictional narrative device. It does not need to count down in real time unless the script specifically requires that.

REWARDS

Create pop-up reward graphics such as:

+100 coins

LEVEL UP

NEW POWER

STAGE COMPLETE

LEGENDARY

UNLOCKED

Use animated scale, bounce, and particles.

SHOP INTERFACE

Use:

Dark panels
Rounded corners
Green ownership indicators
Gold currency indicators
Bright purchase buttons
Clear item names

IMPORTANT

The interface must remain crisp and readable.

Use code to render interface typography.

Do not depend on AI-generated images for important numbers or text.
Keep HUD elements consistent between scenes.
<STEP 10 — CAPTIONS>
Captions are a major part of the video's style.
Use large, bold, animated subtitles in the lower-middle portion of the frame.
FONT

Use a heavy rounded sans-serif font such as:

Montserrat ExtraBold

Fredoka Bold

Lilita One

Choose the closest available font after inspecting the reference.

DEFAULT STYLE

Text: White

Outline: Thick black

Shadow: Subtle dark shadow

Alignment: Center

EMPHASIS COLORS

Use:
Green for wins and rewards
Yellow for important objects

Red for danger and urgency

Pink for funny or dramatic words

ANIMATION

Captions should follow the actual spoken dialogue.

Use word-level timestamps.

Display short phrases rather than long paragraphs.

Animate emphasized words with:

Scale pop

Brief overshoot
Small rotation
Bounce
Color change

Keep words on-screen long enough to read.

No caption should cover the main character's face.

Avoid placing captions directly underneath important game buttons.

A caption should typically contain one to five words, depending on timing and screen space.

<STEP 11 — CAMERA MOVEMENT>

Use the camera as part of the storytelling.
CLOSE-UPS
Zoom into the character's face during surprise, anger, or panic.
WIDE SHOTS
Show obstacle courses, larger environments, and groups of characters.

QUICK ZOOMS

Use fast zooms for jokes and sudden reveals.

CAMERA SHAKE

Use very short camera shakes during collisions, explosions, and shocking moments.

TRACKING SHOTS

Follow the avatar during running and jumping sequences.

PARALLAX

Use separated background layers to create depth.

Do not simply zoom into an entire still image.

Move the actual characters and environmental objects.

Use faster camera motion during chaotic moments and slower movement during dialogue.

<STEP 12 — TRANSITIONS>

Use fast, story-driven transitions.

Include:

Hard cuts: For most dialogue and location changes.

Whip pans: For sudden changes or rapid movement.

Zoom transitions: To enter a game world or highlight a discovery.

Impact cuts: For surprising events.

Character wipes: Let a character or object move across the screen to reveal another scene.

Flash frames: Use sparingly for major reveals.

Avoid excessive transitions that make the video difficult to follow.

Target a new significant visual beat approximately every 1–3 seconds, while allowing longer moments when necessary for a joke or action.

<STEP 13 — PRODUCTION ENGINE>

Use a deterministic animation system.

Preferred tools:

HTML Canvas

JavaScript

SVG

Python

Pillow

OpenCV

FFmpeg

Playwright with Chromium

faster-whisper when available

librosa

NumPy

Install missing dependencies if the environment permits.

CORE ENGINE

Build one JavaScript animation project.
Expose:
https://t.co/KjSvWkCgNW(t)
READY
END
EV
Where:
seek(t) renders the video at timestamp t
READY indicates all required assets are loaded
END is the total duration
EV stores narration and animation timing events

Every frame must be reproducible by seeking directly to its timestamp.

Don't build animations that only work when played from the beginning.
