One of the hottest video technologies to keep an eye out for, Guidi explains, is CinemaScope (2.35:1 or 2.40:1) aspect ratio systems.

“Movies were made in many different aspect ratios over the years, especially as studios tried to outdo each other with large screen productions,” says Guidi. “Until very recently, none [movies] were made with exactly the 16:9 or 1.78:1 ratio chosen as the new widescreen TV standard, but most finally settled in at a ‘matted’ 1.85:1 or widescreen 2.35:1 or 2.40:1.

“The difference between them is small enough that slightly enlarging the 2.40:1 image to fill the height of a now–common 2.35:1 format screen clips less than 2 percent of the picture off each end and slightly less than that from a 2.39:1 image.

“If flat-panel TVs follow the lead of front projectors, they too will probably settle on a 2.35:1 format, but will have to be larger than present panels or they will disappoint viewers when watching SD [standard definition] or HD. For the front-projection market 2.35 is the new standard.

“Hi-Rez Projections Inc. [Guidi’s video repair and manufacturing company] designed and engineered a 2.35 system to retrofit most projectors on the market. Our theater design company — Home Theater By Design — also uses 2.35 to solve sight line problems in the custom theaters we design. It allows us to have a wider screen for a given height and that allows for better sight lines.”
