that's because of the 20% overlap.Ĥ) Now you'll need to define the blend width in the the Stage Setup window.
Edge blending projectors windows#
Here's the result in the preview windows which are in the 1.77 to 1 aspect ratio so as to mimic the 1920x1080 outputs.Īs you can see, the man's right shoulder is shown twice. One of them is shifted all the way to the left (horz pos = -100) and the other is shifted all the way to the right (horz pos = 100.) These two images are routed to Stage 1 and Stage 2 respectively. In this example, I didn't have any 3456 x 1080 content, so I used a 4K James Bond trailer and chopped it to that size using the Chopper actor that says "Ignore Me" If you really had 3456 x 1080 content, you wouldn't need that first chopper.īut next to that, you'll see two Chop Pixel actors, both set to a resolution of 1920x1080 - which is the output size of your two stages. Here's a preview stage that replicates the 3.2 to 1 aspect ratio with some content in it.ģ) The next step is to split your media using Chop Pixels actors. So, to calculate the overlap, take 3840 - 3456 = 384 pixels of overlap (That's 20%, which is a reasonable amount.) If you had no overlap and two 1920x1080 screens, the total width would be 3840 x 1080. Let's say for this example that it will be 3456 x 1080 (i.e., 3456 = 1.8 x 1920 across, 1080 = 1 x 1080 down the resulting aspect ratio is 3456/1080 to 1 = 3.2 to 1.)Ģ) Once you know this, you can calculate the overlap. (The team are testing this blend feature as we speak.) But to try to get you going:ġ) Define the size of the media you'll render. And this is all going to become approximately 1 million times easier in Isadora v3. I don't know if there is a tutorial "out there" but I can say that we don't have one.
Edge blending projectors how to#
Using Edge Blending with such types of screens will avoid such problems, thus rendering better images in terms of resolution, focus and brightness.Said: Is there a tutorial or KB article out there that describes in simple language how to set up multiple projectors and blend their edges in order to project a single image? It can be difficult to project on entire Curved Screen using one single projector because the screen’s arc-cord does not allow any suitable focus point. Indeed, the more projectors used, the shorter the projection distance.Ģ.5 Projection on Specific Shaped Screens (i.e. By using a multi-channel high-resolution image processor, Ultra High- Resolution images can be synthesized.īy using Edge Blending with two or more projectors, the projection distance can be reduced. By using a multi-channel high-resolution projection since the projectors’ performance is combined. The allows a higher resolution projection since the projector’s performance is combined. Multiple projectors are used together to display a single image source, by each projecting a part of the final image. By using Edge Blending, the image projected by multiple video projectors with equal brightness will maintain the original image brightness. When the image projected by a single projected by a single projector is magnified, its overall Brightness will be lowered. The image projected jointly by multiple video projectors is indeed larger than one image projected by one single video projector. 2.1 To Increase the Image’s Size and Integrity:
