Answer #1

Finding size of video file :

= 60 * 1080 * 1920 * 36 * 8400

= 37623398400000 bits

= 4702.9248 Gigabytes   

-------------------------------------------------------------------------------------------------------------------------------------------------------

Finding video bit rate per second:

=  37623398400000 / 8400

= 4478976000 bits/sec

=  4478.976 mbps
