The show was the first to use the "
Syncro-Vox" optical printing system because of budgetary limitations and the pressure to create animation within a tight time frame. Syncro-Vox was invented by
Edwin Gillette, television cameraman and partner in Cambria Studios, as a means of superimposing real human mouths on the faces of animals for the popular "talking animal" commercials of the 1950s.
Clutch Cargo employed the Syncro-Vox technique by superimposing live-action human lips over limited-motion animation or even motionless animation cels. To further cut costs, Gillette and special-effects man Scotty Tomany supplemented Syncro-Vox with other tricks to save time and money. Haas explained, "We are not making animated cartoons. We are photographing 'motorized movement' and—the biggest trick of all—combining it with live action...Footage that
Disney does for $250,000 we do for $18,000." Traditional animation was also employed in the series on occasion. The musical soundtrack to
Clutch Cargo was also limited. Jazz musician
Paul Horn provided a score using bongos, a vibraphone, and a flute. == Episodes ==
