A conferencing service is probably going to want to define the postage stamp as a fixed resolution (and probably framerate), not a scale of the full resolution that can slide around. 

I Agree. 

And we also need to deal with the case where the small is not even the same aspect ratio as the large as that is a very common use case. I think we need max width, max height and do our usual thing of fixing it to landscape mode and then using other things to deal with rotation.
