Adjust Projectors

PreviousBlending & Global AdjustmentsNextIntegrated Videoplayer

Last updated 7 months ago

This set of functionality operates on the projector level. While the overall calibration—such as soft edge, overlap, and warping—remains intact, you can adjust each individual projector in terms of intensity, color balance, and masking. Fine-tuning and precisely adjusting each projector is key to achieving a convincing and seamless overall projection.

One launched, start by selecting a projector to adjust:

  • brightness & color: Adjust so that the projector matches the surrounding ones. Kepp join channels checked to adjust the total brightness; uncheck if you need to adjust the color channels individually

  • projector masking: Masking on projector level is handled here.

    • Clear mask will erase any existing projector mask.

    • from file loads a prebuilt mask (image file, BMP or PNG) where black = masked and white = see-through

    • new/edit mask opens the mask editor to create or edit masks on the fly. Learn more here: Projector masking

Keep Show disply identification checked to see the name of the projector rendered on the projector output. This way you can easily identify which projector you are handling at the moment.

Optimizing blending quality by adjusting projectors

In an ideal world, after running automatic projector alignment will provide a perfect blending between the projectors. However, due to the numerous physical reasons, this is not always the case - especially when working with low-cost/low quality projectors or projectors with a non-standard lens (like UST projectors).

A pretty bad example of a bad blend is shown here:

Use „Adjust Projectors“ make fine adjustments of each projector:

  1. Perform color adjustments for all projectors using several test images.

With proper settings applied, even challenging setups can be handled to get acceptable results:

Start with color matching of the projectors. Having your projectors matched in color improves the blending quality significantly. For color adjustment, use individual color channel faders after unchecking the "join channels" box:

After your projectors are matched and have the same brightness, switch to and fine tune the blending settings, which now work more streamlined on matched projectors.
