Why Aspect Ratios Vary
- Aspect ratios vary because different creators make different choices and old physical film constraints influenced standard sizes.
- Standardization began with the Academy setting 4:3 ratio for sound films in the 1920s, but it evolved with new technologies.
Movies vs TV Aspect Ratio Race
- Television adopted 4:3 aspect ratio to compete with movies but movies responded by creating wider images.
- Various widescreen formats and cropping techniques emerged to differentiate cinema from TV's format.
Origin of 16:9 Aspect Ratio
- The 16:9 aspect ratio was devised as a mathematical compromise between old 4:3 and widescreen 2.35:1 formats.
- It's near 1.85:1, making it suitable for most TV content with minimal black bars.
