This alignment must also include an overlap between the projectors of from 10 to 25 percent of the total screen width. They need to be perfectly horizontal and perpendicular to the screen in both the horizontal and the vertical axes. The video projectors must be physically aligned to provide an image on the screen within one pixel precision, with no distortion. Once you have chosen the right video projectors, you need to follow a few guidelines in order to position them properly. Horizontal and vertical lens shift is required, since lenses with this functionality provide a far more precise result for adjustments. Among the main criteria to consider here is that all the video projectors you use must be identical in terms of color setting (lamp life-time), black adjustment, resolution, etc. The quality of your projectors will have a direct impact on the end result of the Soft Edge.
Another point of note: you should use digital connections between projectors and Mixers/Seamless Switchers as opposed to analog connections, wherever possible. Short-throw lenses can cause hot spots in a rear projection installation.
You can still achieve excellent results with rear projection, as long as you account for the proper space behind your screen, and as long as you do not use projectors with short-throw lenses. You will also have to know which video projectors you plan to use.įirst of all, to ensure optimum results, it is recommended that front projection be used rather than rear projection for Soft Edge Blending. To make an image as seamless as possible, the first element you need to consider is the configuration of your projection. This article aims to clarify some of the key components you should consider if you are interested in incorporating Soft Edge Blending into your worship services. New solutions have been developed that can be used by all types of churches, regardless of their budget or the technical skills of their volunteers. Soft Edge Blending used to be a technology affordable only by mega churches with experienced technicians. Creating a seamless image across a wide surface can be a key element in Houses of Worship who wish to display different elements on multiple screens, with the flexibility of merging all the images into one large, panoramic display. Soft Edge Blending is essentially a term used for creating a large screen image using multiple video projectors with seamless overlapping areas.
You may have already heard the term “Soft Edge Blending” before. There is a practical amount of science that goes on behind the scenes to make this effect possible. There is a captivating effect created by having multiple displays that can be separated and then merged together to form one connected image. Screens are getting larger and projections on multiple surfaces are becoming more common. Undeniably churches are using more and more visual media to capture worshipers’ attention and help to convey the pastor’s message. The demand for visual media is of course increasing in Houses of Worship. Video has proven to be one of the most efficient ways to convey a message to an audience. In our every day lives, we are surrounded by motion graphics, movies and video clips, and we access them through different kinds of displays such as television, smart phones, digital signage devices, and so on.
