When you convert videos to a different quality, you'd want to compare them. While there are objective methods of comparing it, the subjective evaluation by a human is generally more accurate. When looking for solutions, I found a brilliant solution named Vivict. It not only allows you to compare streaming videos, it also allows you to compare local videos, by using the little white icon near the address bar. The best part of Vivict, is that it shows half of one video and half of another, and allows you to move the mouse to view more or less of the video.
Limitation of Vivict: It does not support all video file formats. When I wanted to play an mkv file, it didn't work.
Another solution, is to simply use ffplay like this:
ffplay -f lavfi "movie=leftVideo.mp4,scale=iw/2:ih[v0];movie=rightVideo.mp4,scale=iw/2:ih[v1];[v0][v1]hstack"

I created a program similar to Vivict which shows the videos like this:
