MMLottie-2M Dataset

The first large-scale Lottie animation dataset for multi-modal vector animation generation, containing ~2M samples with diverse motion patterns and visual styles.

Dataset Overview

MMLottie-2M consists of two complementary subsets designed to support comprehensive training for Lottie animation generation:

1. Lottie Subset

Native Lottie animations collected from major online platforms including LottieFiles, IconScout, Flaticon, Iconfont, and Icons8.

Data Processing:

• Removal of irrelevant elements (base64 images, non-visual layers, After Effects expressions)
• Filtering of non-parameterizable layers
• Spatial normalization to 512×512 canvas
• Temporal normalization to 0-16 timestamp range
• Center alignment with aspect ratio preservation

Purpose: Provides authentic motion graphics with complex layer structures and real-world motion patterns.

2. Lottie_SVG Subset

SVG-to-Lottie converted animations generated from the large-scale OmniSVG collection with motion augmentation.

Generation Process:

• Base: Static SVG files from MMSVG-2M dataset
• Motion Transfer: 1,678 canonical motion templates extracted from native Lottie files
• Motion Patterns: Translations, zooms, rotations, opacity changes, and combinations
• Augmentation: Automated keyframe injection to create diverse motion dynamics

Purpose: Decouples visual content from motion semantics, enabling better alignment between visual components and animation conditions. Reduces the path distribution gap and increases animated layer coverage for improved model training.

Key Characteristics:

• Motion signatures encoding temporal patterns (e.g., "fade-in + upward motion + scale-down")
• Semantically clustered motion templates with caption keywords
• Reduces path distribution gap from 24% to <1%
• Increases animated layer coverage from 0% to 16%

Usage

Load specific configuration

from datasets import load_dataset

# Load native Lottie animations
dataset_lottie = load_dataset("OmniLottie/MMLottie-2M", "Lottie")

# Load SVG-based Lottie animations with motion augmentation
dataset_svg = load_dataset("OmniLottie/MMLottie-2M", "Lottie_SVG")

Load subset of data

# Load first 1000 samples from Lottie_SVG
dataset_subset = load_dataset("OmniLottie/MMLottie-2M", "Lottie_SVG", split="train[:1000]")

# Load 10% of Lottie data
dataset_10pct = load_dataset("OmniLottie/MMLottie-2M", "Lottie", split="train[:10%]")

Load all configurations

# Load both configurations together
dataset_all = load_dataset("OmniLottie/MMLottie-2M")

Dataset Fields

Supported Tasks

This dataset supports three multi-modal vector animation generation tasks:

1. Text-to-Lottie: Generate Lottie animations from text descriptions
2. Image-Text-to-Lottie: Generate animations from image + text (foreground motion focus)
3. Video-to-Lottie: Generate parameterized Lottie from video demonstrations

Data Annotation

Annotations are generated using Vision-Language Models (VLMs) with a coarse-to-fine strategy:

1. Coarse: Overall caption covering subjects, objects, motion, color, and style
2. Fine: Temporal details across frames with cues like "begins with" and "then"
3. Emphasis: Keywords highlighting geometry and motion for better text-following
