Some have referred to this method as providing for increased resolution, which is an erroneous assumption – the content resolution STARTED AT, and ALWAYS REMAINS at 1920 x 810, and as such the end resolution presented on-screen can never be greater than that. However, there is the added cost and complexity to consider in such installations with external lenses. That is a key advantage here – no black bars and no possible dark image “halo” above/below the screen when watching content. The top/bottom black bars fall off the chip set. ![]() As an example, when using an outboard cylindrical anamorphic lens the image must first be "stretched". This is a result of the ‘Scope material ALWAYS being provided within the 16/9 delivery image frame. But, is there more resolution when using an anamorphic lens?Īn important point to remember: the 2.35:1 content is ALWAYS presented at 1920 vertical columns x approximately 810 horizontal lines. An advantage here is the use of the complete chip set, providing appx. An external lens is mounted in front of the primary optics. There are three ways to do “anamorphic” – (1) using a high‐quality outboard anamorphic lens, (2) using the on-board lens focus/zoom memory system called VariScope™, and (3) E‐VariScope™, a technology feature built into our outboard ProScaler video processors.īelow is information from one of my training presentations to help further explain these three ‘CinemaScope’ firing methods:ġ/ Anamorphic lens. Eliminating those unwanted black bars is a great experience for the home theater enthusiast, and we at Wolf Cinema wholeheartedly encourage the sale and installation of CinemaScope ultrawide screens and matching projectors - by whichever methodology you chose to deploy. We all want to get rid of the top/bottom “black bars” as embedded in our media providers. We often field questions about anamorphic imaging methodologies, and especially how Wolf Cinema projectors work best on constant height, 2.35:1/2.40:1 CinemaScope™ screens.
