ComfyUI-FlashVSR Introduction
ComfyUI-FlashVSR is an innovative extension designed to enhance video quality through real-time super-resolution processing. Built on the powerful FlashVSR model, this extension allows you to upscale video resolution effectively, making it particularly useful for streaming applications. By integrating with ComfyUI, it provides a seamless experience for AI artists looking to improve video clarity and detail without the need for extensive technical knowledge.
How ComfyUI-FlashVSR Works
At its core, ComfyUI-FlashVSR leverages the FlashVSR model, which is a diffusion-based framework for video super-resolution. This means it uses advanced algorithms to predict and enhance the details in video frames, effectively increasing their resolution. Imagine taking a low-resolution video and transforming it into a high-definition version, much like how a magnifying glass can reveal finer details in a picture. The extension processes video frames in real-time, ensuring that the enhanced video is ready for immediate use, which is ideal for live streaming scenarios.
ComfyUI-FlashVSR Features
- High-Quality Video Upscaling: The extension can upscale videos to 2x or 4x their original resolution, significantly enhancing clarity and detail.
- Multiple Model Versions:
- Full Model: Offers the highest quality output but requires more memory.
- Tiny Model: Balances speed and quality for faster processing.
- Tiny Long Model: Optimized for devices with limited memory, suitable for longer videos.
- SageAttention Optimization: When installed, this feature boosts processing speed by 20-30%. If not installed, the extension defaults to standard processing.
- Smart Tiling: This feature allows the extension to process videos in smaller sections, making it possible to handle high-resolution videos on devices with limited memory.
- Automatic Model Download: The necessary models are automatically downloaded from Hugging Face, ensuring you always have the latest version.
- Audio Passthrough: Maintains the original audio quality and synchronization during video processing.
ComfyUI-FlashVSR Models
The extension supports several models, each tailored for different needs:
- Wan2_1-T2V-1.1_3B_FlashVSR_fp32.safetensors: The latest model offering improved clarity and stability.
- Wan2_1-T2V-1_3B_FlashVSR_fp32.safetensors: The previous version of the main model.
- Wan2.1_VAE.safetensors: Used for video variational autoencoding.
- Wan2_1_FlashVSR_LQ_proj_model_bf16.safetensors: Designed for low-quality projection.
- Wan2_1_FlashVSR_TCDecoder_fp32.safetensors: A decoder for the Tiny model. Each model serves a specific purpose, allowing you to choose based on your quality and performance needs.

Troubleshooting ComfyUI-FlashVSR
Here are some common issues and solutions:
- Missing Model Files: If you encounter a
FileNotFoundErrorforWan2.1_VAE.safetensors, it may be due to a failed download. To resolve this, delete theFlashVSRfolder inComfyUI/models/and restart ComfyUI to trigger a re-download. - Out of Memory Errors: If you experience memory issues, especially with high-quality presets or 4x upscaling, try using the FlashVSR Advanced node with
enable_tilingto reduce memory usage.
