SUMMARY:

Total Bytes read: 741406. Total number of frames: 480.  Length is 19.20 sec

Width: 320	Height: 240
Avg. Frame Size: 1541 bytes + 3 bits  (average rate 308286.04 bits/sec)

Total Compression Rate:  0.67 % of uncompressed 24 bit images
                        =  0.16 bits per pixel

Number of Macroblocks [width * height = sum]: 20 x 15 = 300 per frame
Skipped Macroblocks = 95097 (70.50%), Coded Macroblocks = 39794 (29.50%)
	Coded blocks: 23.77%	[ 17.99  17.85  18.37  17.91  15.79  12.10 ]

MPEG-Viewer requirements:
	Pixel aspect ratio of 1 (VGA)
	Required display speed: 25 frames/sec
	Specified bit rate is variable
	Requested buffer size is 20K ints (16 bits/int).
	And the constrained parameter flag is on.
	The stream does not meet the constrained parameter requirements,
	due to the following factors:
		Bit rate is variable.

Length of vectors in half pixels:
	Horizontal forward vectors, maximum :  31	average:   5
	Vertical forward vectors, maximum   :  31	average:   5

	Horizontal backward vectors, maximum:  31	average:   4
	Vertical backward vectors, maximum  :  31	average:   4
