What is StepVideo T2V?
StepVideo T2V leverages a 30 billion parameter DiT architecture with 3D full attention to generate high-quality videos up to 204 frames from text prompts. It employs a deep compression Video-VAE achieving 16x16 spatial and 8x temporal compression while maintaining exceptional reconstruction quality. The model supports both English and Chinese inputs through dual text encoders, and uses Video-DPO to minimize artifacts and enhance visual output.
Available under the MIT license, StepVideo T2V can be used for commercial purposes, modified, and fine-tuned on specific domains. Performance is validated on the Step-Video-T2V-Eval benchmark, demonstrating superior text-to-video quality compared to other engines.
