Exported video quality is very bad even though the quality is in the highest. How to fix it?
I don't know where did I go wrong because before exporting the video, I made sure that the quality is in the highest setting. At first, I used the preset Youtube 1080p Full HD.

As you can see, the quality is not bad at all
But after exporting, the quality is ruined.

I thought, maybe the preset caused the problem so I customized the setting and set it manually to the highest setting. Now, the file size reached 800+ but the quality is still bad.

I followed a tuns of YouTube tutorials about the proper way of exporting a video in Premiere Pro and I'm sure I followed exactly what they taught me to do. Is it a Premiere Pro bug or it's my fault why the quality sucks? Sorry, I'm still a beginner in Premiere Pro. Thank you and God bless!
