Chris & Trish Meyer
CMG Keyframes is a repository for columns, articles, and videos created by Trish & Chris Meyer of the subject of creating motion graphics using Adobe After Effects and other related programs. It also contains articles on typography, audio, and 3D, as well as links to relevant articles Chris & Trish have published elsewhere. Trish & Chris Meyer are the founders of Crish Design (formerly known as CyberMotion), an award-winning motion graphic design studio that has recently relocated from Los Angeles to the Albuquerque area. Their design and animation work has appeared on shows and promos for CBS, NBC, ABC, Fox, HBO, PBS, and TLC; in opening titles for several movies including Cold Mountain and The Talented Mr. Ripley; at trade shows and press events for corporate clients ranging from Apple to Xerox; and in special venues encompassing IMAX, CircleVision, the NBC AstroVision sign in Times Square, and the four-block-long Fremont Street Experience in Las Vegas. In addition to their motion graphics work, Trish and Chris were among the original users of After Effects, and have written numerous books including "Creating Motion Graphics with After Effects" and "After Effects Apprentice" (both published by Focal Press). They speak regularly at conferences around the country, and perform custom training for studios. Both have backgrounds as musicians, and a close relationship between sound and picture informs much of their work.

Luminance Ranges in VideoDifferent video systems have differing internal definitions of “black” and “white.”
It would seem like a simple concept: “black” is the darkest color you can have; “white” is the brightest color. However, not all video hardware and software think this way. Quite often, systems can go “darker” than black and “brighter” than white, allowing safety margins for certain situations. This means that some systems uses different values for black and white than others. This can cause a lot of problems for a video editor or artist who uses a variety of tools during a production, because images may shift in relative brightness and contrast for no apparent reason. Compounding this problem is a lack of accurate information about how to manage these shifts. But if you ignore them, the results can range from washed-out images to illegal color values. Therefore, you will need to take it upon yourself to be aware of the black and white definitions that different systems are using, and to translate between them as needed. We will also discuss the oft-confused analog concept of “set up” and how it relates to these digital values. It initially requires a bit of a mind-twist, but will pay off in the long run. We will be using After Effects for some of the examples later in this article, but these concepts apply to all systems - so read on… more »
