On Christmas Eve, Santa has one present left to deliver. Then a giant sneeze sends it tumbling into the snowy village below, and the smallest reindeer in the team, a scruffy little fellow called Nib, has to help him find it.
Santa's Tiny Flame is a 3 minute 56 second, 39-scene animated Christmas story made start to finish in Atlabs. We wrote one screenplay, picked the Volumetric Lit 2D style, and Atlabs designed the characters once, turned every beat into its own scene, animated them, and added narration and music. The result has the hand-drawn look with warm, glowing light and soft shadows that films like Klaus made famous. Here is exactly how we made it, with the full script and every scene.

Why long animated Christmas stories work on YouTube
Animated story videos are one of the most popular formats for faceless YouTube channels, and Christmas is their busiest season. Families search for Christmas stories to watch together, kids rewatch favorites, and the same videos come back every December.
Longer stories of three to ten minutes have a few advantages on YouTube:
More watch time per view. A viewer who stays for a four-minute story adds far more watch time than one who watches a short clip, and watch time counts toward monetization.
They come back every year. A good Christmas story is evergreen. It can keep finding viewers each holiday season.
They're easy to turn into Shorts. One long film gives you several short, vertical clips to promote the full video.
They build a series. Characters like Santa and Nib can return in new episodes, which turns one-off viewers into subscribers.
Can you make money with an animated story channel?
Yes, through the YouTube Partner Program, but it takes consistent, original work. To earn ad revenue, a channel needs 1,000 subscribers plus either 4,000 public watch hours in the last 12 months or 10 million Shorts views in the last 90 days (YouTube Help). YouTube also reviews channels against its monetization policies, which since 2025 specifically target mass-produced, repetitive "inauthentic" content.
That's why story quality matters more than volume. Channels that grow tell real stories with characters people care about, and that's where an end-to-end tool like Atlabs helps: you spend your time on the story, and the production is handled for you, so you can publish a full animated episode on a regular schedule. Results are never guaranteed, but the barrier to making a polished, original film is far lower than it used to be.
How to make a long animated Christmas story with AI, step by step
Write a full screenplay. Long stories need structure. Santa's Tiny Flame has four acts: the sneeze, the empty Christmas market, the dark house on the hill, and the miracle. Describe each shot in a line or two and add the narrator's lines.
Describe your characters once. A short paragraph per character is enough: Santa's red coat and round nose, Nib's oversized ears and blue scarf, Mia's blue coat and yellow scarf.
Start a new animated video. Open the Atlabs animated video maker, paste the screenplay, and choose the language, a 16:9 frame for YouTube and the scene pace.
Pick a cinematic style. We used Volumetric Lit 2D for warm, glowing light. There are 50+ styles to choose from.
Let Atlabs produce the film. It designs the characters, locations and props, splits the screenplay into scenes, animates each one, and adds the narration and music.
Polish with the AI editor. Redo any scene's image, motion or narration without touching the other 38, and adjust the timing until the story flows.
Export for YouTube. Download the full film, upload it with a clear title and thumbnail, and cut vertical Shorts from your favorite moments to promote it.
The inputs behind this film
Here is everything we gave Atlabs to make Santa's Tiny Flame. Atlabs did the rest: characters, locations, props, every scene, voices and music.
Project settings
Script: A full screenplay, shown in full below
Language: English
Aspect ratio: 16:9 (landscape, for YouTube)
Scene pace: Fast
Style: Volumetric Lit 2D (Klaus-style lighting)
The input script
This is the script exactly as it was pasted into Atlabs. It's written in plain English: who the characters are, what happens in each scene, and what the narrator says.
The style: volumetric lit 2D, Klaus-style lighting and shadows
Santa's Tiny Flame uses the Volumetric Lit 2D style in Atlabs. It's the look audiences know from Klaus, the 2019 animated Christmas film: characters that feel hand-drawn, but lit like a 3D movie, with soft volume, glowing rim light and deep, painterly shadows.
What makes it special:
Light you can feel. Warm lamplight spills across snow, faces glow on one side and fall into shadow on the other, and every scene has a clear light source.
Hand-drawn shapes with depth. Characters keep the charm of 2D drawing, but shading gives them weight and roundness.
Mood through color. Cold midnight blues set against warm golden light tell the story on their own: the dark cottage is lonely, and the lantern's glow is hope.
It's a perfect match for this story, because the whole film is about light. It starts in a cold, dark night and ends with one match lighting up a whole hillside.
Volumetric Lit 2D is one of more than 50 styles in Atlabs. Others that suit cinematic Christmas stories:
Painterly Cinematic 2D: Rich, film-like hand-painted scenes
Hand-Drawn Dark Fantasy: Moody adventures with a classic feature feel
Whimsical Gouache: Mid-century, Mary Blair inspired holiday art
Storybook Illustration: Gentle bedtime Christmas tales
3D Cartoon: Bright, Pixar-style family films
Claymation: Stop-motion style holiday classics
Meet the cast: characters, locations and props that stay the same in every scene
In a four-minute film, consistency is everything. Atlabs designed each character and prop once and reused them in all 39 scenes, so Santa's round red nose, Nib's crooked antlers and blue scarf, and Mia's yellow scarf never change.
Santa
A cheerful, slightly clumsy Santa with a big round nose, rosy cheeks, a thick white beard and his red fur-trimmed coat.
Nib
The smallest reindeer on the team: scruffy brown fur, oversized ears, short crooked antlers and a little blue scarf.
Mia
A 7-year-old girl with messy brown hair, an oversized blue coat and a knitted yellow scarf, waiting for Christmas in a dark house.
The golden present
The one prop that ties the story together: Santa's last delivery of the night, with a wooden toy horse inside.
The locations
Village Rooftops
Crooked snowy rooftops and chimneys under a starry midnight-blue sky.
Abandoned Christmas Market
An empty town square with wooden stalls, amber lanterns and a giant decorated tree.
Snowy Hilltop Cottage
A lonely dark cottage with a frosted window, a brass lantern and a crooked fence.

Frequently asked questions
How do I make a long animated story with AI?
Write a full screenplay with acts, shots and narration, paste it into Atlabs and choose a style. Atlabs designs the characters, locations and props once, splits the story into scenes, animates each one, and adds narration and music. Santa's Tiny Flame runs almost four minutes across 39 scenes, all from one screenplay.
How do I keep characters consistent in a long AI animation?
Use a tool that designs each character once and reuses that design in every scene. Atlabs creates a character sheet for Santa, Nib and Mia before animating, so their faces, outfits and colors stay the same from scene 1 to scene 39.
What is the Klaus animation style?
It's the look of the 2019 film Klaus: hand-drawn 2D characters lit like a 3D film, with soft volume, glowing light and painterly shadows. In Atlabs you can get a similar look with the Volumetric Lit 2D style.
Can I make money with AI animated story videos on YouTube?
Yes, if your channel joins the YouTube Partner Program. You need 1,000 subscribers plus either 4,000 public watch hours in the last 12 months or 10 million Shorts views in the last 90 days, and your videos must follow YouTube's monetization policies, which reject mass-produced, repetitive content. Original stories with recurring characters are the safest path.
How long should an animated story be for YouTube?
Three to ten minutes is a common length for animated stories. It's long enough to build watch time and short enough for kids and families to finish. Santa's Tiny Flame runs 3 minutes 56 seconds.
Do I need animation skills to make a 4-minute animated film?
No. You write the story. Atlabs handles design, animation, narration, music and editing, and you can change any scene by asking the AI editor.
Can I turn a long animated story into YouTube Shorts?
Yes. Pick your best moments, like Santa's sneeze or the lantern lighting up the hill, and export them as short vertical clips that point viewers to the full film.
Make your own long animated Christmas story
Santa's Tiny Flame started as a one-page screenplay about a sneeze, a lost present and one last match. Atlabs turned it into a four-minute, 39-scene film with glowing Klaus-style light, consistent characters, narration and music, all in one place. Your channel's first Christmas story can start the same way.
