Key Features of Pusa V1
Text-to-Video Generation
Create videos directly from text descriptions with high coherence and quality. Simply input a prompt and watch as Pusa V1 generates realistic video content.
Image-to-Video Conversion
Transform static images into dynamic videos by using them as starting frames. Pusa V1 can animate any image with natural motion and transitions.
Start-End Frame Control
Provide both starting and ending images to guide video generation. The AI fills in the intermediate frames to create smooth transitions between the two points.
Video Extension
Extend existing videos by providing the first few frames. Pusa V1 can naturally continue video sequences, making short clips longer and more complete.
Vectorized Timestep Adaptation
Advanced timing control technology that allows precise management of events and actions within generated videos, resulting in more realistic and coherent content.
Multiple Camera Views
Generate videos with different camera angles and perspectives, including 360-degree views, providing comprehensive visual coverage of generated scenes.
Examples of Pusa V1 in Action
1. Text-to-Video Generation
Pusa V1 can create videos from simple text prompts. For example, describing "a car changing from gold to white" produces a smooth transformation video. The model handles complex scenarios like "a person eating a hot dog" with remarkable realism, capturing natural movements and expressions.

2. Image-to-Video Animation
Using a single image as a starting point, Pusa V1 can animate static content. The model excels at creating natural motion, whether it's a person getting up from a chair and stretching, or complex scenes with multiple moving elements.
