How video software works: frames, resolution, frame rate, color, and gamma explained in plain language.
Video processing is the study of what a video signal is and what software does to it. It starts with the basic structure: a video is a series of still frames shown in rapid succession, and its look is set by resolution, frame rate, and aspect ratio.
Color is the second half of the story. Real-world color becomes numbers through color spaces such as RGB, and brightness is shaped by gamma correction so that encoded values look natural on a display.
The articles here explain these building blocks in plain language, with the concepts first and the formats second.
