+### Anime4K
+
+Enlarge the video by 2 times using Anime4K. **Remember to install and configure [JRE 12](https://www.oracle.com/technetwork/java/javase/downloads/java-archive-javase12-5440181.html) path in the configuration file.**

 ### CPU
 
 Enlarge the video to 1920x1080 using the CPU. You may also use the `-r/--ratio` option. **waifu2x-based upscalers potentially run much slower than using a GPU, but Anime4K is more CPU-dependant**. The configuration file for this method is similar to the previous methods.
