Method & Evidence

AimTo develop a framework for tokenizing and autoregressively generating vector animations, specifically using the Lottie format, from natural language or visual prompts.

MethodFramework Development and Machine Learning

ProcedureThe researchers developed a Lottie Tokenizer to encode layered geometric primitives, transforms, and keyframe-based motion into token sequences. They also curated a large dataset (LottieAnimation-660K) of Lottie animations and static images. This tokenizer and dataset were used to fine-tune a multimodal model (Qwen-VL) into LottieGPT, enabling it to generate vector animations from prompts.
