Calculating media size intensity numbers 1 1 0 1 0 0 1 1 pixels column &rows. 1024 column & 768 rows colour model rgba (red green blue alpha) transparency for alpha. 4 channel with each with 8 bits 4 x 8 x 1024 x 768 = 25,165,824 bits data size. 320 x 240 = 76,800 pixel rgb ( 8 bits) x 24 = 1,843,200 bits data size. 1920 x 1080 x 32 = 66,355,200 x 30 = 1,990,665,000 bits data size. Aspect ratio shape of example 3 is 16 x 9 which is square. 44,100 hz x 16 bits x 2 channels = 1,411,200 (1 sec) x 74 minutes x 60 seconds = 96,000 hz x 24 bits x 8 channels x 3. 5 minutes (210) = 3,800,000,000 bits data size / 8. Bits have resource costs, not free kilo 1000 or 1024 is unclear mega 1,000,000 or 1024 x 1024 or 1000 x 1024.
