Type an animal, a fact or a story idea. ShortFast writes the script, builds a scene for every line from real wildlife footage or in a 3D, clay or paper look, narrates it and adds captions.
To make an animal video with AI, type the animal or the fact into the box above, pick a look, and ShortFast writes the script, builds a scene for each line, narrates it and burns in captions. Built from documentary stock footage of real animals, the default here, a video typically costs about 12 credits; in a still-image style such as 3D Animation or Paper Cutout, about 25. The box sets the video up; generating it needs a ShortFast account, which starts with a 3-day trial for $1.
An animal video makes one promise: this is what the animal really does. Many of the most shared animal 'facts' are myths, and a realistic AI clip of an animal doing something it never did is a scene that didn't happen. So the steps below put a source behind every fact before the render, keep real behaviour in real footage, and tell invented stories in looks nobody mistakes for film.
How it works
One species, one surprising fact and the reason behind it: 'how does a sea otter stay warm with no blubber?' is a video; 'amazing ocean animals' is a channel. For a story, one animal hero, one problem and one age to tell it to.
Documentary footage when the video explains what a real animal does, 3D Animation for fun facts and stories for kids, Claymation for funny ones, Watercolor for bedtime, Science 3D for what happens inside an animal's body, Paper Cutout for fables and nature stories.
Check each fact and number against a zoo, a natural history museum, a university or a government wildlife agency, and note the page for the post text. Edit the draft or paste your own script; in script mode ShortFast narrates your words as written, and the narration can't be changed after the render.
A stock clip shows the species, but not always the behaviour the narrator describes; when no clip fits a line, the pipeline uses an AI image instead; and AI images can get anatomy wrong. Swap any scene that shows the wrong animal, the wrong behaviour or an extra leg for another image or one you upload, adjust captions, music, title and post text, then re-render.
Download the video, or connect TikTok, Instagram and YouTube. If the videos are made for kids, set that in YouTube Studio first: ShortFast doesn't set an audience on the videos it posts. An automation writes the next episode for each posting slot, a new animal in the same tone, format and length, and checks recent titles so it doesn't repeat itself.
Documentary stock footage is the default here and the cheapest look, at about 12 credits a video: licensed clips of real animals, with nothing to attribute. When a video explains what a real animal does, real footage is the honest picture. A clip shows the species, though not necessarily the exact behaviour the narrator describes, and when no clip fits a line the pipeline falls back to an AI image, so check every scene before you post.
3D Animation draws every scene with animated-movie characters, and ShortFast lists it for kids, fun facts and stories: a penguin dad's winter told for a five-year-old, or a fun fact explained by a friendly cartoon animal. Claymation turns each scene into a handmade stop-motion clay set, which suits funny animal stories and the youngest viewers. Watercolor's soft storybook washes are the bedtime look, for a slow story about an owl or a fox. Each typically costs about 25 credits a video.
Science 3D renders microscopic, medical-style scenes and is listed for health, biology and medicine, which suits what happens inside an animal: the gizzard where an ostrich grinds its food with the sand, pebbles and small stones it swallows, for example. Paper Cutout builds each scene from layered handmade paper and is listed for fairy tales and nature, which makes it the look for fables and nature stories: Aesop's animals, a migration, a forest through the seasons. Both cost about 25 credits.
None of these five drawn looks passes for wildlife footage, which matters for the labels below. Each can also turn every image into a short AI video clip. That raises a typical video to about 464 credits, so keep it for a series' strongest episodes; documentary footage doesn't have that option.
"How does a sea otter stay warm in a cold ocean with no blubber? Unlike whales and seals, it relies on dense, clean, water-resistant fur and a high metabolism, eating about a quarter of its body weight in food every day. Oil on that fur can destroy its insulation, and the otter can die of the cold. Documentary look, calm narrator, end on why that makes oil so dangerous to otters."
"A winter in the life of an emperor penguin dad, for ages 4 to 8: in the dark Antarctic winter he keeps one egg on his feet for nine weeks without eating, living on his fat. He huddles with other dads, up to 10 in a square metre on the coldest days, and they take turns between the cold edge and the warm middle. 3D Animation look, warm narrator, short sentences, end as the chick hatches."
"Aesop's The Crow and the Pitcher, for ages 5 to 9: a thirsty crow can't reach the water in a tall, narrow pitcher, so it drops in pebbles until the water rises. Then the true part: in 2009 a University of Cambridge study gave four rooks, members of the crow family, a tube of water with a worm floating on top, and they dropped in stones to reach it. Paper Cutout look, curious narrator."
Each fits the 400-character limit of the box above, and every fact in them is on a page you can link in the post text: the US Fish and Wildlife Service for the otter, the British Antarctic Survey and the Australian Antarctic Division for the penguins, and the University of Cambridge for the rooks. In a fable, let the narrator say where the story ends and the science starts.
Many of the animal 'facts' everyone knows are myths, and an AI draft can repeat them because they are everywhere. Ostriches don't bury their heads in the sand. San Diego Zoo Wildlife Alliance explains that an ostrich that senses danger and can't run away flops to the ground and stays still, with its head and neck flat on the ground in front of it; they are lightly coloured and blend in with the soil, so from a distance only the body shows. If a fact is something everyone already knows, check it before it carries a video.
Some myths were filmed. Lemmings don't commit mass suicide: the Alaska Department of Fish and Game calls it a myth, and says the lemming scenes in White Wilderness, a 1958 Disney nature film, were faked, according to a 1983 investigation by a Canadian Broadcasting Corporation producer. The animals were thrown off a cliff by the filmmakers, and the 'migration' was staged with careful editing, tight camera angles and a few dozen lemmings on a snow-covered turntable. Real lemmings disperse when the food runs out, and some drown crossing water. A realistic AI clip can now invent in seconds what that crew staged with a turntable.
Give every fact a source you could link to, such as a zoo or aquarium, a natural history museum, a university or a government wildlife agency, and name it in the post text. Say what a study showed and what it didn't: the Cambridge rooks solved Aesop's puzzle in an experiment, and the university's write-up says rooks are not believed to use tools in the wild. Use 'about' or 'up to' for numbers that vary from one animal to the next.
Never present AI-generated animal behaviour as real footage. A realistic AI clip of an animal doing something it never did, or never could, is what YouTube calls a realistic scene that didn't actually occur. ShortFast's AI Images and AI video styles can draw realistic animals too, and the same rule applies to them. Real behaviour belongs in real footage; an invented story belongs in a look nobody mistakes for film, such as 3D Animation or Paper Cutout. That is why this page is about explaining real animals and telling animal stories, not about the viral 'real' AI animal clip.
YouTube requires creators to disclose AI-generated or altered content that seems realistic, including content that 'generates a realistic scene that didn't actually occur'. You answer Yes under 'AI use' when you upload; for videos ShortFast posts for you, the setting is in YouTube Studio. Non-realistic content needs no disclosure, and neither does using AI for the script or the captions, and YouTube says disclosing alone won't limit a video's audience or its eligibility to earn money. Stock clips of real animals are real footage; a footage video's AI fallback image that could pass for a photo of a real animal is the case to answer Yes for, or to swap. 3D, clay, watercolor and paper scenes are plainly not footage.
TikTok requires a label on AI-generated content that shows realistic-looking scenes or people, while artistic styles and generic text-to-speech narration don't need one. These videos are made with AI from script to voice; TikTok encourages labeling AI-generated content and says the setting won't affect distribution, so turning it on costs nothing.
Both platforms have animal-welfare rules that shape what a wildlife video can show. YouTube doesn't allow content where humans coerce animals to fight, 'content that shows animal rescue that is staged and puts the animal in harmful scenarios', or 'graphic content that features animals and intends to shock or disgust', but it does allow 'animals fighting in the wild, like in a nature documentary'. TikTok says: 'We don't allow animal abuse, cruelty, neglect, or any other form of animal exploitation.' So in a video about a predator, tell the hunt and keep the kill off screen.
Compilations are a monetisation question. YouTube's reused-content policy lists 'short videos you compiled from other social media websites' and 'content uploaded many times by other creators' among what can't earn, says it 'applies even if you have permission from the original creator', and looks at the channel as a whole, so monetisation can be removed from the entire channel. A feed of other people's viral animal clips is what that list describes; licensed footage under a script written for one animal is the other side of the line.
If your animal videos are made for kids, say so. YouTube requires every creator to tell it whether their videos are made for kids, under an agreement with the US Federal Trade Commission, and its factors include animated characters or cartoon figures. ShortFast doesn't set an audience on the videos it posts, so set your channel's audience in YouTube Studio before the first one goes out.
Stock footage shows the species, not necessarily the behaviour. Ask for a penguin feeding its chick and the clip may show penguins walking across the ice. The narration carries the fact, so check that no scene contradicts it, and swap any that does for another image or one you upload.
When no clip fits a line, the pipeline falls back to an AI image, so a footage video can still contain AI scenes. Never tell viewers every scene is real footage; check every scene, and answer Yes under 'AI use' if a realistic AI image stays in.
AI images can get anatomy wrong: the wrong number of legs or toes, the beak or markings of another species. That goes for the drawn looks too, so check every AI scene and swap any that's wrong.
It doesn't animate maps. A migration's route has to be told, not drawn: put the distances in the narration, which the captions show word by word, or upload a map you made or have the right to use.
The narration is fixed once rendered. You can swap scenes, edit captions, change music, title and post text, and re-render, but correcting a fact the narrator says means generating again.
An automation has no approval step. In an animal series the AI picks each new animal and writes its script, and every episode posts automatically or arrives by email, so choose email delivery and check each episode's facts and scenes before you post it. The next two episodes are queued: you can edit their captions, scenes and post text, re-time, pin or delete them, but not change their script. Put your rules in the series brief, up to 500 characters: one animal per episode, facts from zoos, museums, universities or wildlife agencies, nothing graphic.
None of these channels use ShortFast; they show what animal audiences come back for. Ze Frank's True Facts series gives each video to one animal or one question, in titles such as 'True Facts: Geckos' and 'True Facts: Is The Goffin's Cockatoo The Smartest Bird?', with a voiceover that mixes the facts with reactions to the footage. Deep Look, from KQED and PBS Digital Studios, uses 'macro photography and microscopy in glorious 4K resolution' to get close to small animals, in titles such as 'These Mudskipper Fins Were Made For Walking'. Animalogic calls itself 'a deep dive into the biology, behavior, and evolutionary logic' of animals, and many of its titles correct a belief, such as 'We Were Wrong About What's Killing Monarchs'. TierZoo talks about animals as if they were characters in a video game, in titles such as 'The Mammal Tier List' and 'Are Stingrays Overpowered?'; its stated goal is 'to get gamers interested in zoology'.
Deep Look shoots its own macro footage; that look comes from its cameras, not from stock clips. What all four share is one animal or one question per video and an angle of their own: a narrator's reactions, extreme close-ups, a correction, a game. That is the part to copy; the scenes, the voice and the captions are the part ShortFast handles.
