| # FlashVSR Model Mirror (AEmotionStudio) |
|
|
| 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. |
