Create a claymation videoClaymation is the look of stop-motion clay animation: chunky hand-sculpted characters, visible thumbprints and tool marks, felt and cardboard props, and small sets lit like a tabletop. It feels handmade and a little imperfect, which is exactly its charm. Food explainers, funny stories, failed inventions and kids content use it because it makes ordinary things look playful and worth a second look.
Real stop-motion takes days of posing figures frame by frame. ShortFast gives you the look without the modeling clay: paste a script or start from a topic like "How chocolate is made, from bean to bar," and it writes or keeps the narration, splits it into scenes and draws each one as a clay set. The same clay characters and palette run through the whole video, with captions, a voice and music added.
Start from an idea such as "How chocolate is made, from bean to bar", or paste a script you already wrote and ShortFast keeps your words.
Every scene gets its own picture, and a shared palette, setting and recurring characters keep each image in the Claymation look from the first scene to the last.
Pick one of 21 narration voices. Captions are burned in, and the Claymation defaults (natural pace, background music, transitions) are already set. You can change any of them.
Download the video, auto-post it to TikTok, YouTube Shorts and Instagram Reels, or turn the theme into an automated series that makes a new episode on a schedule.
Clay signals effort and play at the same time. The slight lumps, fingerprints and wobbly edges tell the viewer a person could have made this, and that handmade texture stands out in a feed full of polished footage and glossy renders. It invites a closer look, which is the whole game in the first two seconds of a short.
The style also has comedy built in. Clay characters have simple faces with big mouths and round eyes, so exaggerated reactions land easily: a chef watching a cake collapse, an inventor staring at a machine that just fell apart. Food looks especially good in clay, with glossy chocolate, lumpy bread and bright vegetables that read clearly on a small screen.
The strongest topics are processes and small stories. How a food is made suits clay because each step becomes its own set: cocoa pods on a tree, beans drying in the sun, a factory of clay machines, a finished bar. Funny failed inventions, a day in the life of a tiny chef, animal stories and simple lessons for kids work for the same reason. Each scene has one object or character doing one thing.
Clay is a weaker choice for anything that needs to look precise or serious. Data-heavy money topics, medical detail, news and true crime lose credibility in plasticine, and fine detail like maps, charts or small text does not survive the clay texture well. Real places also turn into toy versions of themselves, which is lovely for a playful travel piece and wrong for a documentary. A documentary or cinematic style suits those better.
Write in beats, one action per scene. Process videos almost script themselves: "First the beans ferment for days. Then they dry in the sun." Each sentence hands the scene writer a clear clay set to draw. For a funny video, set up the joke in one scene and pay it off in the next, so the reaction gets its own frame instead of being squeezed into the setup.
The style starts on a normal pace, with music and transitions on. A new image around every five seconds suits clay, because viewers like to take in the little details of each set, and a light soundtrack with gentle transitions fits the toy-box mood. If your script is a quick countdown of failed inventions, fast pace keeps the jokes moving. All three settings can be changed.
Stop-motion is defined by movement, so this is the style where the Animate images option earns its place most. It turns each clay scene into a short AI video clip in the same look, so figures move instead of holding a pose. It costs more credits, billed per second of video, and is available for videos up to two minutes.
Give ShortFast one theme and it makes a new claymation video on a schedule, every day, twice a day or a few times a week. Each episode covers a new topic on the theme, and the video is emailed to you or posted to your accounts. Themes that work well in this style:
A playbook for running a faceless facts channel: formats that add editorial value, ready-to-use hooks, a full sample script, what to put on screen, and an honest look at RPM and YouTube's inauthentic-content rules.
