To edit video correctly you must read its color metadata with ffprobe, understand the YUV model, limited versus full range, BT.601/BT.709 gamuts and transfer functions, apply the appropriate YUV‑to‑RGB matrices, convert gamuts to BT.709, and re‑encode with matching color parameters.
This article introduces the basic concepts of audio and video capture—including sampling, quantization, PCM storage, YUV formats, camera operation, and pixel resolution—explaining how these technologies enable non‑contact, fully digital government procurement services during the COVID‑19 pandemic.
The article explains common color models such as grayscale, RGB and YUV, describes image fundamentals like resolution and aspect ratio, outlines typical storage formats (RGB, YUV420P, NV12/NV21) and their bit‑depth considerations, and introduces video basics including frame rate, compression stages and HDR mapping.
This article explains how digital images are captured as pixel arrays, describes the physiological basis of color perception, compares RGB and YUV color spaces, and introduces video compression concepts such as spatial and temporal redundancy, frame types, and common encoding formats.
