What is the difference between warping and keystoning?<\/h3>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
\n\t\t\t\t
\n\t\t\t\t\t\t\t\t\t

Keystoning is a basic digital or optical adjustment used to maintain a rectangular image when a projector is tilted. Warping is a much more advanced process that manipulates and distorts a specific grid of the projected image to compensate for highly irregular, curved, or spherical surfaces.<\/p>

Why do I need optimized video codecs for mapping?<\/h3>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
\n\t\t\t\t
\n\t\t\t\t\t\t\t\t\t

Optimized codecs like HAP, DXV, and ProRes are specifically designed to be decoded by your computer’s graphics card (GPU) instead of the processor (CPU). This is essential in video mapping because it allows your computer to smoothly play multiple high-resolution videos simultaneously without lagging.<\/p>

What is edge blending and when should I use it?<\/h3>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
\n\t\t\t\t
\n\t\t\t\t\t\t\t\t\t

Edge blending is a technique used to fluidly merge the overlapping edges of beams from several adjacent projectors. You should use it when you need to create a single, massive panoramic image that is continuous and homogeneous in brightness, which cannot be achieved with just one projector.<\/p>

How can I make my visuals react to music?<\/h3>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
\n\t\t\t\t
\n\t\t\t\t\t\t\t\t\t

To make visuals react to music, you use audio-reactive features within your mapping software. The software analyzes the frequency variations (bass, mids, treble) of a real-time audio source (connected via an Audio Input) and dynamically generates visual effects or animations that pulse to the beat.<\/p>
