Speaking of AJA, the following is taken directly from my Web page (URL
in sig).
AJA Video Systems offers a free program for calculating data rates and
storage space requirements for video files based upon user-selected
frame size, frame rate, and compression parameters. For maximum
accuracy, audio sampling rate, bit depth, and number of channels can
also be specified. Both Mac and Windows versions of the program are
available at the links given below (look under "Utilities and Optional
Downloads"). Use of an AJA capture card (Kona, Xena, etc.) is not
necessary in order to use these programs.
