- What is Soft Edge Blending?
Soft Edge Blending is essentially a term used for creating a large screen image using multiple video projectors
with seamless overlapping areas. Creating a seamless image across a wide surface is important if one
wishes to display different elements on multiple screens, with the flexibility of merging all the images into one
large, panoramic display.
The Soft Edge Blending is often used in Rental and Staging, live events, corporate, government and church
market.
- Soft Edge Blending configuration
To make an image as seamless as possible, the first element you need to consider is the configuration of your
projection. You will also have to know which video projectors you plan to use.
The quality of your projectors will have a direct impact on the end result of the Soft Edge. The video projectors
must be physically aligned to provide an image on the screen within one pixel precision, with no distortion.
They need to be perfectly horizontal and perpendicular to the screen in both the horizontal and the vertical
axes. This alignment must also include an overlap between the projectors of from 10 to 25 percent of the total
screen width.
Now that your video projectors are perfectly positioned, you can begin to adjust the settings that will create
your seamless blend.
