    Video File Size Calculation

    Need help.

    How much file space (flash drive/disk drive, etc) in KB would be required if I wish to record a video for 120 minutes, with the following parameters:
    Encoding- MPEG-4
    Resolution- 640 x 480 pixels
    Frame Rate- 30 fps

    Please show me the calculation so that I can do the maths in future.

    Appreciate your help.

    Wikipedia: MPEG-4
    MPEG-4 is efficient across a variety of bit-rates ranging from a few kilobits per second to tens of megabits per second.
