## How to Use
|
|
|
|
### PyTorch Inference
|
|
|
|
```bash
|
|
# download model
|
|
wget https://github.com/xinntao/Real-ESRGAN/releases/download/v0.2.3.0/RealESRGANv2-animevideo-xsx2.pth -P experiments/pretrained_models
|
|
# inference
|
|
python inference_realesrgan_video.py -i inputs/video/onepiece_demo.mp4 -n RealESRGANv2-animevideo-xsx2 -s 2 -v -a --half --suffix outx2
|
|
```
|
|
|
|
### ncnn Executable File
|
|
|
|
#### Step 1: Use ffmpeg to extract frames from video
|
|
|
|
```bash
|
|
ffmpeg -i onepiece_demo.mp4 -qscale:v 1 -qmin 1 -qmax 1 -vsync 0 tmp_frames/frame%08d.png
|
|
```
|
|
|
|
- Remember to create the folder `tmp_frames` ahead
|
|
|
|
#### Step 2: Inference with Real-ESRGAN executable file
|
|
|
|
1. Download the latest portable [Windows](https://github.com/xinntao/Real-ESRGAN/releases/download/v0.2.3.0/realesrgan-ncnn-vulkan-20211212-windows.zip) / [Linux](https://github.com/xinntao/Real-ESRGAN/releases/download/v0.2.3.0/realesrgan-ncnn-vulkan-20211212-ubuntu.zip) / [MacOS](https://github.com/xinntao/Real-ESRGAN/releases/download/v0.2.3.0/realesrgan-ncnn-vulkan-20211212-macos.zip) **executable files for Intel/AMD/Nvidia GPU**
|
|
|
|
1. Taking the Windows as example, run:
|
|
|
|
```bash
|
|
./realesrgan-ncnn-vulkan.exe -i tmp_frames -o out_frames -n RealESRGANv2-animevideo-xsx2 -s 2 -f jpg
|
|
```
|
|
|
|
- Remember to create the folder `out_frames` ahead
|
|
|
|
#### Step 3: Merge the enhanced frames back into a video
|
|
|
|
1. First obtain fps from input videos by
|
|
|
|
```bash
|
|
ffmpeg -i onepiece_demo.mp4
|
|
```
|
|
|
|
```console
|
|
Usage:
|
|
-i input video path
|
|
```
|
|
|
|
You will get the output similar to the following screenshot.

|
|
</p>
|
|
|
|
2. Merge frames
|
|
|
|
```bash
|
|
ffmpeg -i out_frames/frame%08d.jpg -c:v libx264 -r 23.98 -pix_fmt yuv420p output.mp4
|
|
```
|
|
|
|
```console
|
|
Usage:
|
|
-i input video path
|
|
-c:v video encoder (usually we use libx264)
|
|
-r fps, remember to modify it to meet your needs
|
|
-pix_fmt pixel format in video
|
|
```
|
|
|
|
If you also want to copy audio from the input videos, run:
|
|
|
|
```bash
|
|
ffmpeg -i out_frames/frame%08d.jpg -i onepiece_demo.mp4 -map 0:v:0 -map 1:a:0 -c:a copy -c:v libx264 -r 23.98 -pix_fmt yuv420p output_w_audio.mp4
|
|
```
|
|
|
|
```console
|
|
Usage:
|
|
-i input video path, here we use two input streams
|
|
-c:v video encoder (usually we use libx264)
|
|
-r fps, remember to modify it to meet your needs
|
|
-pix_fmt pixel format in video
|
|
```
|
|
|
