Create Amazing Videos with AI Power
Transform your ideas into stunning videos in minutes.
What is StepFunT2V?
StepFunT2V is an advanced model that turns text into videos. Imagine having a tool with 30 billion tiny helpers (parameters) that can create videos up to 204 frames long! It uses a special technique called Video-VAE to compress video data, making it faster and more efficient while still keeping the video quality high. Plus, it can understand both English and Chinese, thanks to its smart text encoders.
To make sure your videos look great, StepFunT2V uses a method called DiT with 3D full attention to clean up any noise in the video frames. It also applies a technique called Video-DPO to make the videos look even better by reducing any unwanted artifacts. This model has been tested on a special benchmark called Step-Video-T2V-Eval, proving that it creates top-notch videos compared to other tools out there.
Key Features of Step-Video-T2V?
State-of-the-Art Model
Step-Video-T2V is a cutting-edge text-to-video model with 30 billion parameters, capable of generating videos up to 204 frames long. It leverages advanced techniques like Video-VAE for deep compression and DiT with 3D full attention for high-quality video generation.
Bilingual Capability
The model uses two bilingual text encoders to process prompts in both English and Chinese, ensuring a wide range of user inputs can be effectively transformed into stunning video content.
Enhanced Visual Quality
With the integration of Video-DPO, Step-Video-T2V reduces artifacts and enhances the visual quality of videos, aligning the output more closely with human preferences and expectations.
How to Use Step-Video-T2V
Model Download
Download the Step-Video-T2V model from platforms like Huggingface or Modelscope. Ensure you have the necessary storage and system requirements.
Setup Environment
Install Python >= 3.10.0, PyTorch >= 2.3-cu121, and other dependencies. Use Anaconda or Miniconda for environment management. Clone the repository and set up the environment using conda.
Run Inference
Use the provided inference scripts to generate videos. Adjust hyperparameters like infer_steps, cfg_scale, and time_shift for optimal results. Ensure you have a compatible NVIDIA GPU for best performance.
Featured Examples
The Magical Forest
The boat travels through a gorgeous magical forest, where roses bloom as if enchanted, their petals fluttering in the air, forming a sharp contrast with the surrounding lava. In the distance, towering mountains are looming in the clouds, like a fantasy landscape painting painted by a powerful magician.
Fitness Routine
In the video, a woman lies on a blue yoga mat and does sit-ups. She is wearing a sports suit, sports gloves, and sneakers. She holds a large blue fitness ball above her head each time she stands up, showing good core strength. The background is a simple room with plenty of light and dark walls. The video is shot with a fixed lens, clearly showing the details of the fitness movements, with a realistic style.
Sunlit Portrait
The video shows a close-up of a person in the sun. A fence and some buildings can be seen in the background, and the sun shines softly on the person's hair, adding a sense of warmth to the picture. The person's expression is natural, sometimes smiling, sometimes blinking, giving people a relaxed and happy feeling. The whole video uses close-ups to highlight the person's expressions and details, with a realistic style.
Spacecraft Corridor
The handheld tracking camera glides through the corridor of the spacecraft, capturing the astronauts' focused and orderly demeanor as they work. The camera zooms in on an operator, who is staring at the screen intently, with beads of sweat on his forehead, and the low hum of the surrounding instruments heightens the sense of urgency.
Joyful Skipping
On a green lawn, a man in a light blue short-sleeved T-shirt and dark blue shorts, holding a blue skipping rope, and a woman in a rose-red sports vest and rose-red shorts, holding a red skipping rope, happily skipping rope side by side. The camera is clear, fixed, and shot horizontally. The background is a dense forest, and the sun is bright. The woman has long flowing hair and a smile on her face, and the man also smiles. In the middle of the video, the woman stops skipping rope, opens her arms, faces the camera, and then skips rope again.
