I am simply looking for the formula that should be used here. All the results I've found base "finding the bitrate" off of already existing video. I'm talking about LIVE streaming. (indeterminate length)

So, I know some basic parts of it, but I just need to know if I'm right or missing anything.

For Kbps:

Resolution * Framerate / 1024

Is it really that simple? Audio would be a separate element for our purposes here. Am I missing anything from this formula?

(Coming up with a proposal of what amount of bandwidth would be required, relative to possible resolution options, so I just need to be sure that I'm not missing anything or inaccurate about it)
