the video and audio files you create can be very large files. however, there is a simple formula that helps you estimate the amount of disk space you need per uncompressed avi file.

    the formula for calculating the approximate file size of an avi (uncompressed video) file is:

    height x width x color depth x fps x length (in seconds)

    8,000,000

    for example you have a video with the following characteristics:

    1 video window size = 320 (h) x 240 (w)

    2 color format = 24-bit rgb

    3 frames per second (fps) = 30

    4 length = 60 seconds

    320 x 240 x 24 x 30 x 60

    8,000,000

    this results in an avi file of approximately 414.72 megabytes.
