V 4mp4 🎉 👑

Capable of generating 204-frame videos (roughly 6-7 seconds at 30 fps) with realistic textures and motion.

The model is built on a massive, 30-billion parameter architecture designed for deep understanding of text prompts and visual generation. v 4mp4

The Step-Video-T2V (v 4mp4) is a state-of-the-art text-to-video AI model developed by Stepfun AI that, as of early 2025, has garnered attention for its ability to generate high-quality, long-duration videos. It focuses on producing 204-frame videos with a high degree of fidelity using advanced architecture. Capable of generating 204-frame videos (roughly 6-7 seconds

It uses a specialized VAE for video generation, achieving 16x16 spatial and 8x temporal compression. This allows for high-quality video reconstruction while accelerating training and inference. as of early 2025
