On codecs and bitrate? It's basically codec = file type (.avi, .mp4) and bitrate is how much data is sent per second for the video. Videos only track what changed between frames, so a video of a still image can be 4k with a really low bitrate, but if things are moving it'll get really blurry with a low bitrate even in 4k.
"File types" like avi, mp4, etc are container formats. Codecs encode video streams that can be held in different container formats. Some container formats can only hold video streams encoded with specific codecs.
ah yeah I figured it wasn't quite right, I just remember seeing the codec on the details and figured it was tied to it, thanks.
