Emu Video: AI Text-to-Video Generation by Meta
What is Emu Video?
Emu Video is a cutting-edge AI tool developed by Meta AI for generating videos from text prompts. It stands out for its ability to create high-quality, 4-second videos at 16 frames per second (fps).
How does Emu Video work?
Emu Video employs a factorized generation approach based on diffusion models. This process is divided into two key steps:
- Image Generation: First, the system generates an image based on the provided text prompt.
- Video Generation: Next, it generates a video conditioned on both the initial text prompt and the generated image.
This factorized approach makes Emu Video highly efficient, requiring only two diffusion models to produce 512px videos.
Key Features and Advantages
- High-Quality Output: Emu Video produces videos with impressive visual fidelity and coherence.
- Efficiency: The factorized generation method allows for efficient training and video creation.
- State-of-the-Art Performance: Emu Video outperforms other text-to-video generation models in terms of both quality and faithfulness to the prompt, as determined by human raters.
Performance Comparison
In evaluations against state-of-the-art models, Emu Video consistently delivered superior results. It was compared against models such as Make-a-Video (MAV), Imagen-Video (Imagen), Align Your Latents (AYL), Reuse & Diffuse (R&D), Cog Video (Cog), Gen2, and Pika Labs.
