# CharacterShot: Controllable and Consistent 4D Character Animation

[**CharacterShot**](https://arxiv.org/abs/2508.07409) is a controllable and consistent 4D character animation framework that enables the creation of dynamic 3D characters (i.e., 4D character animation) from a single reference character image and a 2D pose sequence.

## Introduction

CharacterShot utilizes a powerful 2D character animation model based on a DiT image-to-video architecture. It lifts these animations to 3D using dual-attention modules and camera priors to ensure spatial-temporal and spatial-view consistency. The final representation is optimized using neighbor-constrained 4D Gaussian Splatting, resulting in stable and continuous character representations.

The model was trained on **Character4D**, a large-scale dataset containing 13,115 unique characters with diverse appearances and motions.
