Aspect Ratios
Canvas size, crop, letterbox, pillarbox, and oddball screen formats.
Basics you can see
Projection, video, displays, signal flow, and live production systems. No filler. One idea at a time. Move the control and see what changes.
Each module gets a short explanation, a visual model, a practical rule, and an interactive control when interaction teaches better than text.
Throw ratio, zoom, lens shift, focus, cage alignment, convergence, and blend overlap.
Canvas size, crop, letterbox, pillarbox, and oddball screen formats.
Pixel pitch, cabinet count, processor outputs, and viewing distance.
Where scaling, conversion, sync, latency, and format mismatches enter the chain.
Teach the thing. Skip the brochure voice.
If the concept is spatial, temporal, or signal-based, draw it.
End with the field move: what to check, what to adjust, what to avoid.
