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.

Mastering field rendering may not top your list of creative exercises, but you can’t achieve professional results without it.
If you thought most NTSC video ran at 29.97 frames per second, that’s only half the story - literally. It actually runs at a speed of 59.94 fields rather than 29.97 frames per second (fps), with pairs of fields “interlaced” to form a complete frame (see the illustration at left). When you shoot footage with your camcorder, it does not record whole video frames unless you are explicitly in a special mode known as “progressive scan.” Instead, most of the time it captures one field, then a second field, and lays these fields down in a linear fashion to tape.
