No more hand waving than declaring that all videos should be less than 200MB. Not that i am saying that is our current procedure, but it is close. :-)

But more seriously, just asking about bitrate, without extra information about the actual size (width/height) of the video, how big the ASL interpreter is presented in the video (just a tiny picture-in-picture in the corner, or actually taking up half the image?) etc, is not likely to yield any tangible/actionable answers...
