Framepack AI

공유

Main Features

  • Fixed-Length Context Compression: Compresses all input frames into fixed-length context 'notes', preventing memory usage from scaling with video length
  • Minimal Hardware Requirements: Generate 60-120 second 30fps high-quality videos with only 6GB VRAM, compatible with RTX 30XX, 40XX, and 50XX series NVIDIA GPUs
  • Efficient Generation: Approximately 2.5 seconds per frame on RTX 4090, reducible to 1.5 seconds per frame using teacache optimization
  • Strong Anti-Drift Capabilities: Progressive compression and differential handling of frames by importance mitigates the 'drift' phenomenon
  • Multiple Attention Mechanisms: Support for PyTorch attention, xformers, flash-attn, and sage-attention

Technical Features

  • Based on next-frame prediction neural network structure
  • Computational load decoupled from video length
  • Supports FP16 and BF16 data formats
  • Open-source and freely available on GitHub

Target Users

  • Content creators
  • Video production professionals
  • AI researchers
  • Users with consumer-grade GPUs

Core Advantages

  • Extremely low VRAM requirements (6GB sufficient)
  • Capable of generating long videos (60-120 seconds)
  • Open-source and free with no usage restrictions
  • Runs locally on devices, protecting privacy

Usage Workflow

  1. Prepare input image
  2. Configure generation parameters
  3. Start video generation
  4. Export high-quality video

FAQs

Q: What is Framepack AI? A: A specialized neural network structure for AI video generation using 'next frame prediction' technology, compressing input context information to fixed length, making computational load independent of video length.

Q: What are the hardware requirements? A: Requires NVIDIA RTX 30XX, 40XX, or 50XX series GPU with at least 6GB VRAM, compatible with Windows and Linux systems.

Q: How long can generated videos be? A: Can generate 60-120 second 30fps high-quality videos depending on hardware configuration and optimization techniques used.

Q: What makes it different from other video generation models? A: Main innovation is fixed-length context compression, avoiding the linear growth of context length with video time faced by traditional models, significantly reducing VRAM requirements and computational costs.

Q: Is it open-source? A: Yes, developed by ControlNet creator Lvmin Zhang and Stanford professor Maneesh Agrawala, code and models are publicly available on GitHub.
