Mirror of [FlashVSR v1.1](https://github.com/OpenImagingLab/FlashVSR) model weights for [ComfyUI-FFMPEGA](https://github.com/AEmotionStudio/ComfyUI-FFMPEGA).
## Model Files
| File | Description | Size |
|---|---|---|
| `FlashVSR1_1.safetensors` | DiT v1.1 weights (one-step diffusion backbone) | ~5.7 GB |
| `Wan2.1_VAE.safetensors` | WAV2.1 VAE decoder | ~254 MB |
| `LQ_proj_in.safetensors` | Low-quality 4× projection encoder | ~576 MB |
| `TCDecoder.safetensors` | Tiny Conditional Decoder (for Tiny/Tiny-Long modes) | ~181 MB |
| `Prompt.safetensors` | Cross-attention conditioning embeddings | ~4 MB |
## Variants
- **FlashVSR Full** — Best quality, full VAE decode (~12-16 GB VRAM)
- **FlashVSR Tiny** — Fast mode with TCDecoder (~8-12 GB VRAM)
- **FlashVSR Tiny Long** — Streaming for long videos, lowest VRAM (~8-12 GB)
All variants share the same weight files. The variant determines which pipeline and decoder components are used at inference time.
## Usage
These models are automatically downloaded by [ComfyUI-FFMPEGA](https://github.com/AEmotionStudio/ComfyUI-FFMPEGA) when selecting any `flashvsr_*` model from the `upscale_model` dropdown.
