<p><b>Overview of the Vector Animation Data Construction Pipeline.</b>
|
||
<b>Data Collection & Conversion :</b> We convert SVG assets into static Lottie files and apply randomized animation effects to generate effect-tagged animated Lotties. In parallel, we gather professionally created Lottie animations from five online platforms and perform thorough filtering and cleaning. <b>Data Processing :</b> Each animation undergoes spatio-temporal normalization, followed by video rendering and random keyframe extraction. <b>Data Annotation :</b> Finally, we provide multi-granularity annotations emphasizing geometric structure, color attributes, and motion characteristics.</p>

<h3>OmniLottie Model</h3>
|
||
<p><b>Overview of OmniLottie.</b>
|
||
<b>Lottie Structure :</b> We reorganize the Lottie JSON representation, with a particular focus on the structure of its layers, including both common layer attributes and five special layer types. <b>Lottie Parametrization :</b> The hierarchical JSON format of Lottie is flattened into a sequence of function calls, which are further parameterized to define a dedicated vocabulary and token set for Lottie. <b>OmniLottie :</b> Built upon this parameterization, OmniLottie extends Qwen2.5-VL with a new tokenizer and vocabulary for Lottie, and is trained on our curated Lottie dataset.</p>
