Learning Motion Graphics in 21 Days - Day 7
DAY 7
INTRODUCTION TO KEYING
What is Keying? Keying is defining transparency by a particular color value or luminance value in an image. When you key out a value, all pixels that have colors or luminance values similar to that value become transparent.
Keying makes it easy to replace a background, which is especially useful when you work with objects too complex to mask easily. When you place a keyed layer over another layer, the result forms a composite, in which the background is visible wherever the keyed layer is transparent.
PS: Always execute the video lessons over and over again as much as you possibly can. The aim is to learn and master motion graphics as best as you can in 21 days
