The two most-watched cable channels in our household are CNN and Speed (guess who watches which). Speed just started a new game show called “Pass Time” where several of the bumpers as well as in-show inserts exhibit the maddening two steps forward/one step back staggered motion of fields that have been reversed (maybe they thought it was a “look”...). CNN isn’t immune to this either; through the years some of their graphics have also exhibited this reversed-field judder.
This prompted us to upload an updated version of a classic column we wrote on interlacing, field rendering, and separating fields; you can find it here. But like any good motion graphics designer who tries to reverse-engineer any graphic they see on television, this has led us to speculate what might have been at the root of this particular problem.
Chris & Trish Meyer are the founders of CyberMotion, an award-winning Los Angeles motion graphic design studio. Their design and animation work has appeared on shows and promos for CBS, NBC, ABC, Fox, The Learning Channel, HBO, and PBS. CyberMotion was one of the first studios to create major release film opening titles using desktop tools (including major films such as The Taleneted Mr. Ripley), and they have also created promotional and trade show videos for corporate clients from Apple Computer to Xerox. They specialize in unusual format videos, having animated for IMAX, CircleVision, the NBC AstroVision sign in Times Square, and the four-block-long Fremont Street Experience in Las Vegas.
