How to Create Long Cartoon Videos with AI – Step by Step

This tutorial by Youri van Hofwegen walks through a complete, step-by-step workflow for creating long AI cartoon videos with fully consistent characters using OpenArt, Cling 2.6, and the Nano Banana Pro image model. The core technique centers on OpenArt’s grab-frame-to-video feature, which extracts the final frame of any generated clip and uses it as the starting frame for the next scene — enabling seamless narrative continuity across multiple generations without visible quality drops between shots.

The video begins with character creation inside OpenArt using Nano Banana Pro, valued here for its strong prompt adherence and high-resolution output. The creator builds a Pixar-style alien named Zumi, generates an initial animated clip with Cling 2.6 at 5 seconds, then progressively extends the story across four separate generations — each one picking up exactly where the last left off. A second character is introduced mid-sequence, demonstrating that OpenArt’s consistency tools apply not just to the original character but to newly introduced ones as well.

For creators working on animated shorts, YouTube content, or social media storytelling, this workflow offers a practical solution to one of AI video’s most persistent problems: maintaining visual coherence across scenes. The specific model choices (Cling 2.6 with audio enabled, Nano Banana Pro for stills) and the frame-chaining method give viewers a directly replicable process rather than a high-level overview.
