False 70) What software allows us to do pathbased animation? Flash 71) What does a bigger FPS imply?

72)
73)
Tweening: short for inbetweening, the process of generating intermediate frames between two images to give the appearance that the first image evolves smoothly into the second image Onion Skinning: is a 2D computer graphics term for a technique used in creating animated cartoons and editing movies to see several frames at once

81) Which one will the human eye detect changes in more easily? How does this help us with compression? human eye is more sensitive to variations in brightness (our eyes have more rods which detect brightness. Cones detect color but we have fewer of them) THUS video compression works on reducing color so compress and get rid of color information and keep the brightness 82) USB—FIREWIRE difference physically look different transfer rate 83) Know that another name for firewire is (I.LINK – IEE1394) Transfer data from camcorder to another medium Faster rates 84) know what FIREWIRE was transmitted originally at 400m BPS 85) Know definition of ‘analog’ records electrical signals/pulses directly onto a medium(like a tape) with a magnetic encoding 86) Know definition of ‘digital’ Records a binary code (string of 1s and 0s) compressed on magnetic tape or other media 87) “MEMORIZE FOR THE EXAM” in order to accommodate the color they went from 30 to 29.97 FPS (digital video)
