Choosing a projector for video mapping requires calculating the throw ratio (distance divided by image width) to select the correct lens. You must also dimension the lumen output based on ambient light and your surface area. Avoid extreme optical corrections; instead, rely on intuitive software like HeavyM to easily warp and map your shapes without degrading image quality. Turning the constraints of your location into clear hardware choices is the foundation of a successful video mapping project. To achieve a sharp, high-contrast image without extreme corrections, you need to understand projection ratios, zoom limits, and light output. \ud83d\udc49 Ready to test your hardware?
