Video File Size Calculation for a Single Frame
Select your image/video resolution: pixel count for the width and pixel count for the height.
select image size
total pixels per image (l*h) 345,600 px (or 0.3 Megapixels)
now we add color (RGB resp. YUC)
pixel count with color (l*h)*3 1,036,800 px
now add bit depth to each pixel
bits per pixel (bpp)
bits per color channel 8-bit =  8,294,400 bits
or in byte (bit/8) 1,036,800 Byte = 1,012.50KB/frame

Video File Size Calculation for running Frames

Calculation Help:
If each pixel is represented by 1-bit, each frame has 0 color bits (0 pixel count x3); or in Bites this would equal to 0.00 Bites (8 bits in one Bite) (1024-based)

For example, this is the ways we export most of our 8mm film transfered to a final file

Background: During the past three years, we experienced the need for increased hardware upgrades. So we kept asking ourselves, "What kind of storage capacity is needed, and what kind of data transfer rate will it require?" Also our website estimation tool required this information. So we went ahead an programmed this calculator. We hope this calculator will helps you, as much as it heps us make an informative decision.
