Minimum-Maximum (video)

In the context of video encoding and analysis, the term "Minimum-Maximum" typically refers to a pair of values representing the lower and upper bounds of a specific parameter within a video stream. This parameter could be anything measurable or configurable, such as:

• Bitrate: A video codec might dynamically adjust the bitrate based on content complexity, with a minimum bitrate to ensure basic quality and a maximum bitrate to prevent excessive bandwidth usage. The Minimum-Maximum bitrate values define this range.

• Quantization Parameter (QP): QP values control the level of compression applied to each frame. A Minimum-Maximum QP pair defines the allowable range, impacting the balance between file size and visual fidelity. Lower QP values mean less compression, higher quality, and larger file sizes, and vice versa.

• Frame Rate: While less common, a video might dynamically adjust its frame rate within specified limits. A Minimum-Maximum frame rate would define the lowest and highest permissible frame rates.

• Color Values: In some specialized applications, Minimum-Maximum might refer to the range of allowable color values (e.g., luminance or chrominance) to ensure compliance with broadcast standards or artistic intentions.

The "Minimum" value represents the lowest acceptable or permitted value for the parameter in question, while the "Maximum" value represents the highest. These bounds are often used to constrain encoding or analysis algorithms, preventing them from exceeding predefined limits. The specific interpretation and application of "Minimum-Maximum" depends heavily on the context in which it is used within video technology.
