Canon Video bitrate

hi all,
I posted this in another forum before I realized this is the better forum for my question:

I am trying to get a better understanding of the image quality of various Canon cameras particularly in relation to bit rate. The Canon 80d say it has a max bitrate of 90mbps and the Canon C100 MK1 says it has a max bitrate of 24mbps and the C300 MK1 around 54mbps. Does this mean that the 80d shoots at a higher bitrate than these other cameras?
How does the 35mm sensor relate to this ( if at all). What exactly is the bitrate? assuming that all these files are being compressed in ALL-I what does the bitrate correlate to? How does the codex relate to the bitrate?

In short, yes. The 80D is five years newer than the C300 and C100, and thus, incorporates some better features! Usually, that highest bitrate is reserved for the 59.94 framerate--I don't know that for sure on the 80D, but that's what I suspect.

The bitrate literally refers to how much data is being compressed into each frame--the higher the bitrate, the less compression. In general, that's what you need to know. However, codec DOES matter, and the C300's mpeg2 MXF files are very different from the h.264 that you'll get in the 80D and C100.

Don't make the mistake of believing bitrate and codec are the only thing that matters. The C300 and C100 have very nice dynamic range, and the integrated XLR audio features are priceless for a working shooter. Both these cameras, despite the fact that they competed with cameras that shot 10-bit 4:2:2 files, were extremely popular for working shooters who weren't going to do a ton of color work; they get clean, nice-looking footage with no fuss.
