I need some help here. So I've been rendering my videos fine and the quality looks really decently good in the video itself, but for some reason when I upload it to youtube, it become a blurry mess. Is someone able to assist me?

Could it be the bitrate? If there are a lot of different colours on the screen or a fairly intense pattern on screen then the bitrate tends to mess up the video's consistency...that's all I can think of though
