Multiple-image Network Graphics
The ambitious, complex, and largely obsolete animated cousin of PNG.
MNG (Multiple-image Network Graphics) was designed as the animated equivalent of the PNG format. Just as PNG was created to replace GIF for static images, MNG was intended to replace GIF for animations, offering superior compression, full alpha transparency, and complex features like nested loops and sprites. However, its complexity led to poor adoption.
MNG is a stream-based format that shares the same chunk structure as PNG. It can contain embedded PNG (lossless) or JNG (JPEG-based) images. Unlike a simple filmstrip, MNG is a scriptable animation format; it supports 'sprites', frame deltas (only updating changed pixels), and complex composition rules.
Published in 2001 by the creators of PNG. Despite high hopes, browser vendors (like Mozilla) eventually removed support due to the large code footprint and complexity of the library (libmng). The simpler APNG format won the browser war for 'animated images'.
Kodak Cineon
A pioneering 10-bit logarithmic format designed by Kodak for digital film scanning and mastering.
The Cineon format (.cin) was developed by Kodak in the early 1990s as part of their Cineon Digital Film System. It was designed to capture the full dynamic range of film negatives. Unlike standard linear image formats, Cineon stores data in a 10-bit logarithmic density format, which closely mimics the response of film to light. This allows it to preserve highlight and shadow details that would be lost in linear 8-bit formats.
Cineon files use 10 bits per color channel (Red, Green, Blue), packed into 32-bit words (with 2 bits of padding). The key feature is the logarithmic encoding: pixel values represent printing density rather than linear brightness. A value of roughly 95 represents 'D-min' (clear film base), and the values scale up to represent increasing density. This allows the format to store a dynamic range that exceeds standard video formats.
Introduced in 1993, the Cineon system was the first end-to-end 4K digital intermediate workflow for motion pictures. While the hardware system was discontinued in 1997, the file format became the industry standard for visual effects and digital mastering until it was eventually superseded by the more flexible DPX (Digital Picture Exchange) format, which is directly based on Cineon.
