The following is general information about the 235-4P (4-Perf) system, a type of motion picture film camera and film format.

Key Features and Benefits
Four Perforations: The film advances four perforations (or “perf”) per frame, a key feature that distinguishes it from other formats like 3-perf. The four-perf system is a long-standing standard in the film industry, offering great stability and compatibility with a wide range of equipment.

Wider Frame: The 4-perf system uses more film real estate per frame, resulting in a larger negative. This larger negative provides a higher-quality image with finer detail and less grain when enlarged. This makes it an excellent choice for theatrical release where a high-resolution image is critical.

Compatibility and Standardization: It is a globally accepted standard, which ensures compatibility with a vast network of post-production facilities, projectors, and scanners. This reduces the risk of technical issues and makes the workflow smoother.

Robustness: The 4-perf system is highly reliable and less prone to mechanical failure due to its established design. It’s often used for visual effects work where frame stability is of utmost importance.
