Document Summary

Where will i be viewing my video: on the web, on cd, dvd video. Assume we have a video that is: 1440 x 1080 pixels 1,555,200 pixels per frame, 24 bit colour, 30 fps, 1 second long, audio is stereo (2 channels, audio is 48,000hz, 16 bit = 1,536,000 bits. Video: 1,555,200 x 24 bits per pixel (colour) = 37,324,800 bits per frame, 37,324,800 x 30fps x 1 second = 1,119,744,000 bits/8 = 139,968,000 = 133mb. Total: 133mb + 188kb = ~133mb lots of storage for just 1 sec, thus a dvd could hold 35 seconds of uncompressed video. Lower the frame size of the video. If it was 640 x 480, change it to 320 x 240, less pixels. Lower the frame rate of the video (frames/sec: changing the frame rate by will generally the file size. Pick a file that does higher compression. Codec is a piece of code or program.
