The 1.33:1 aspect ratio was established as the standard for sound film by the American Academy of Motion Picture Arts and Sciences (AMPAS) in 1932. At this time, the film industry was undergoing a transformation: the introduction of sound film necessitated adjustments, and AMPAS defined clear technical standards. The 4:3 aspect ratio (1.33:1) was recognized as an international standard and remained the dominant cinematic format for over 50 years.

The 1.33:1 aspect ratio is important for my composition: I work with a more square frame that offers more height than modern widescreen formats. The format requires a different lighting design, focusing on frontal and top-bottom axes.
As a director, I choose 1.33:1 for classic storytelling or when I'm consciously aiming for a timeless, retrospective look. It's particularly suited for psychological dramas and character-driven stories.
