video codecs

A video codec is a technology that compresses and decompresses digital video files. "Codec" stands for coder-decoder. When you record or stream a video, the codec reduces its file size for easier storage and faster transmission without significantly lowering quality. Different codecs use various methods for compression. For example, H.264 is common for online videos due to its efficient compression, while HEVC (H.265) offers higher quality at smaller sizes, ideal for 4K content. When you watch a video, your device uses the codec to decode the file, allowing you to see and hear the content smoothly.
