 ## Description
 
 Video2X is an automation software based on waifu2x image enlarging engine. It extracts frames from a video, enlarge it by a number of times without losing any details or quality, keeping lines smooth and edges sharp.

 ## Quick Start
 
-To enlarge a video on a computer with NVIDIA GPU
+### Nvidia CUDA (waifu2x_caffe)
+
+Enlarge the video to 1920x1080 using CUDA. You may also use the `-r/--ratio` option.
 
 ```bash
-$ python video2x.py -i video.mp4 -o video.mp4 -m gpu --width=1920 --height=1080
+$ python video2x.py -i video.mp4 -o video_output.mp4 -m gpu --width=1920 --height=1080
 ```
 
-To enlarge a video on a computer with CPU
+### Nvidia CNDNN
+
+Enlarge the video to 1920x1080 using CUDNN. You may also use the `-r/--ratio` option.
 
 ```bash
-$ python video2x.py -i video.mp4 -o video.mp4 -m cpu --width=1920 --height=1080
+$ python video2x.py -i video.mp4 -o video_output.mp4 -m cudnn --width=1920 --height=1080
+```
+
+### AMD or Nvidia (waifu2x_converter_cpp OpenCL)
+
+Enlarge the video by 2 times using OpenCL. Note that `waifu2x_converter_cpp` doesn't support width and height.
+
+```bash
+$ python video2x.py -i video.mp4 -o video_output.mp4 -m gpu -r 2
+```
+
+### CPU
+
+Enlarge the video to 1920x1080 using the CPU. You may also use the `-r/--ratio` option. This is potentially much slower than using a GPU.
+
+```bash
+$ python video2x.py -i video.mp4 -o video_output.mp4 -m cpu --width=1920 --height=1080
 ```
