"Assuming the bitrates are the same, 48fps will require 80% of the bandwidth needed to handle 60." Not exactly - while your 80% approximation is true for uncompressed footage, h.264 encoded video and essentially every modern day video compression schema will inherit data from the frame(s) before it. The higher the framerate, the less (generally speaking) the images will change between frames - leading to a reduction in data per frame. Here's an example: File 1: http://files.jjcm.org/60fps.mp4 http://files.jjcm.org/60fps.mp4 - 127KB File 2: http://files.jjcm.org/48fps.mp4 http://files.jjcm.org/48fps.mp4 - 119KB As seen here, the 48fps video 94% of the size of the 60 fps video. Granted, this is a singular example, but at least it supports the concepts that I described above.
