TRY IN 720p60fps
A direct render from ReplayMod for Minecraft 1.16.4
Before being processed in YouTube, the input video was rendered in 60fps 1280x960, with a bitrate of 25.607mbps, in 4:3 display ratio.
It works better than the last test video I did, as the 720p60fps setting appears on the quality menu. I still don't like how YouTube compresses videos, because I noticed that clarity of the output is lower, compared to the crisp-clear input.
I also noticed that the output resolution was downscaled from 1280x960 to 960x720. Will be uploading more higher resolution test videos to see if I can get 1080p.
