You would need to replace all the bulbs each time one failed to ensure similar characteristics and some additional calibration would probably still be required to produce ideal picture quality. If multiple lamp-based projectors are used, not only would the bulbs fail regularly, they will dim at different rates, causing color and brightness shifts. This is a tool aimed for experienced users (like VJs), and uses the Syphon framework to stand between any Syphon-enabled player (like Modul8 and many others) and the projection mapping tool (like MadMapper or Arena). Projectors with laser light engines offer a significant advantage over a bulb-based system in a long-term projector blended installation. Blendy VJ is an Edge Blend solution for multiple projectors. Laser projectors are ideal for edge blending applications. However, Edge Blending can’t be combined with pixel shifting but that is okay in many situations where maximum flexibility is more important than absolute resolution. The result is an image that looks seamless, like it’s being displayed by a single projector.
You can use the projector’s Black Level setting to make the difference even less noticeable.
Under the Blend Range menu’s sub-setting, you can fine-tune the blend’s starting position and the width of the blended area. If you need more light output or want to utilize multiple projectors to display a larger, wider aspect image, many projectors are equipped with several features to make that goal easier.īy utilizing Edge Blending, you can split an image over multiple projectors and display it as one large image while reducing the hard transition from one projector to another.
