Cartoon video for TikTok: designing for the scroll

The advantage animation has here

A TikTok feed is overwhelmingly camera footage — faces, rooms, streets. A drawn frame registers as different before the viewer has processed what it is, and that split second of pattern interrupt is the scarcest resource on the platform.

This argues for a distinctive style rather than a safe one. Claymation, paper cut-out and rubber hose looks stand out; generic flat vector blends into the sea of app ads.

Vertical from the start, never cropped

Generate at 9:16. Cropping a horizontal cartoon to vertical fails because the model composed for the wider frame — the character sits at a third, the action reads across the width, and the crop removes the interesting part.

One constraint catches people constantly: if you supply a source image or video, the output inherits that file's shape, not the ratio you selected. Crop your source picture to 9:16 before uploading.

Keep the subject in the middle 60% vertically and clear of the right edge. Roughly the top tenth and bottom fifth are covered by interface.

The first two seconds

Open mid-action on something that raises a question. Not a character walking into frame — a character already doing something inexplicable. Why is that robot holding a birthday cake in a snowstorm?

Openings that waste the moment: a logo, a title card, a slow fade, a character introducing itself. Every one of them spends attention you have not earned yet.

Design the loop

TikTok restarts automatically and a rewatch counts. A clip whose final frame flows back into its first gets watched two or three times by the same viewer without a conscious decision.

Build it deliberately: supply the same image as both the first and last frame, and the model animates a journey that returns to where it started. Even without that, end on the composition you opened on and avoid an ending that resolves too firmly — a character settling into stillness signals "over" and breaks the cycle.

Assume no sound, generate with sound anyway

Most first views are muted, so the visual must carry the meaning alone. Watch your own clip on mute; if you cannot follow it, neither can the audience.

Still generate with audio on. Synchronised sound noticeably lifts the experience for viewers who do unmute, and the platform measures their engagement too. Then burn in captions — large, high contrast, in the middle band, no more than six words at a time.

Length and volume

Shorter than you think. A visual gag lands at six to ten seconds. A satisfying loop wants eight to fifteen. Only a genuine mini-story needs the full thirty, and stretching a thin idea to fill the runtime is the most common self-inflicted wound.

Because a variant now costs minutes rather than a production day, the correct strategy is volume with variation: one body, three different openings, posted across a week. The winner is regularly not the one you predicted.
