A better understanding of bitrate

I've been using OBS for a few years now, but I haven't tooken the time to do research about it, all I knew was higher bitrate equals higher quality. However, I want a deeper understanding of this, I knew about the OBS forums since I have been using obs for so long, so I want to know, when there is movement, (using constant bitrate) Why does the quality degrade and look more pixelated? This only happens when there is a lot of movement on the screen, however when it's a stand still the picture doesn't look that bad. How come big streamers have their streams look so consistent and frame and picture quality. Summary: I want to know how big streamers get their so consistent and picture perfect quality image for streaming/recording, is it simply just higher bitrate?

Bitrate defines how much data is used for the difference between frames. If you limit how much data is used, then when there's a lot of motion it has be heavily compressed to fit it in, resulting in pixelation.

It's a balance between bitrate, frame rate & resolution, and the amount of motion in the content. Larger streamers often use dual-PC streaming with a slower x264 preset, which provides a slightly better compression algorithm than the default.

Thanks for the information, I will continue pursue my adventure into dual pc streaming, as it has been proven time and time again that it is awesome. I will make another post about my efforts in this area, but for now thanks for the support.
