✨ **Highlights**

✅ [add realesr-general-x4v3 and realesr-general-wdn-x4v3](https://github.com/xinntao/Real-ESRGAN/commit/b827be13a1db242ebaea1be8669c62b757bd2796). They are very tiny models for general scenes, and they may more robust. But as they are tiny models, their performance may be limited.
✅ [support denoise strength for realesr-general-x4v3](https://github.com/xinntao/Real-ESRGAN/commit/576aaddfaf1dec031cdf580924c00f4b29b9b35a). You can use the **-dn** option to adjust the denising strength. Denoise strength. 0 for weak denoise (keep noise), 1 for strong denoise ability. Only used for the realesr-general-x4v3 model.
✅ [update inference_video: support auto download](https://github.com/xinntao/Real-ESRGAN/commit/61e81d3108f9437a9d97b02fd94439e9fc191ed0). You do not need to download models explicitly. If the models are not download, they will be downloaded automatically.

✅ [support ffmpeg stream for inference_realesrgan_video](https://github.com/xinntao/Real-ESRGAN/commit/cdc14b74a54e4247581b31c66caf93ea9e0cf159)
✅ [fix colorspace bug & support multi-gpu and multi-processing](https://github.com/xinntao/Real-ESRGAN/commit/8cb9bd403e0b8206eb69780b97b35cf7aa84bd4e)
✅ [Added GPU selection feature to python inference](https://github.com/xinntao/Real-ESRGAN/commit/6b15fc693646da1f16ba38ee47cf71a285f08390)
✅ [deal with flv format](https://github.com/xinntao/Real-ESRGAN/commit/e5e79fbde32cf96720d484511fbae2272144beb6)

The major update: 🎉

✅ We update the **RealESRGAN AnimeVideo-v3** model, which can achieve better results with a faster inference speed.
The improvements are:
- **better naturalness**
- **Fewer artifacts**
- **more faithful to the original colors**
- **better texture restoration**
- **better background restoration**

You can find more details in [anime video models](https://github.com/xinntao/Real-ESRGAN/blob/master/docs/anime_video_model.md) and [comparisons](https://github.com/xinntao/Real-ESRGAN/blob/master/docs/anime_comparisons.md).

The models can be downloaded from [realesr-animevideov3](https://github.com/xinntao/Real-ESRGAN/releases/download/v0.2.5.0/realesr-animevideov3.pth).

✅ We also update the ncnn.
Portable [Windows](https://github.com/xinntao/Real-ESRGAN/releases/download/v0.2.5.0/realesrgan-ncnn-vulkan-20220424-windows.zip) / [Linux](https://github.com/xinntao/Real-ESRGAN/releases/download/v0.2.5.0/realesrgan-ncnn-vulkan-20220424-ubuntu.zip) / [MacOS](https://github.com/xinntao/Real-ESRGAN/releases/download/v0.2.5.0/realesrgan-ncnn-vulkan-20220424-macos.zip) **executable files for Intel/AMD/Nvidia GPU**.

Have a nice day 😸 and happy everyday 😃

I am happy to add a simple logo to Real-ESRGAN 😋 (designed by myself! and inspired by the [4K logo](https://www.google.com/search?q=4k+logo))
So I release a new version~

You can see it on [ReadMe](https://github.com/xinntao/Real-ESRGAN)

Long long time no see😺

We have added small models for **anime videos**: 🎉

You can find demos and usages in https://github.com/xinntao/Real-ESRGAN/blob/master/docs/anime_video_model.md


:white_check_mark: We add small models that are optimized for anime videos :-)

Now we have added two models.

| Models | Scale | Description |
| ---------------------------------------------------------------------------------------------------------------------------------- | :---- | :----------------------------- |
| [RealESRGANv2-animevideo-xsx2](https://github.com/xinntao/Real-ESRGAN/releases/download/v0.2.3.0/RealESRGANv2-animevideo-xsx2.pth) | X2 | Anime video model with XS size |
| [RealESRGANv2-animevideo-xsx4](https://github.com/xinntao/Real-ESRGAN/releases/download/v0.2.3.0/RealESRGANv2-animevideo-xsx4.pth) | X4 | Anime video model with XS size |

This release also contains the following files:

- RealESRGANv2-animevideo-xsx2.pth
- RealESRGANv2-animevideo-xsx4.pth
- realesrgan-ncnn-vulkan-20211212-windows.zip
- realesrgan-ncnn-vulkan-20211212-macos.zip
- realesrgan-ncnn-vulkan-20211212-ubuntu.zip

See you again 😺

**The major update**: :tada:

- :white_check_mark: We add [*RealESRGAN_x4plus_anime_6B.pth*](https://github.com/xinntao/Real-ESRGAN/releases/download/v0.2.2.4/RealESRGAN_x4plus_anime_6B.pth), which is optimized for **anime** images with much smaller model size. More details and comparisons with [waifu2x](https://github.com/nihui/waifu2x-ncnn-vulkan) are in [**anime_model.md**](https://github.com/xinntao/Real-ESRGAN/blob/master/docs/anime_model.md)
