A codec is a tool that helps make video files smaller while keeping their quality. Think of it like a special translator that can compress large video files into smaller ones for easier sharing and streaming, then decode them back for viewing. When you see this term in a resume, it usually means the person knows how to work with different video formats and can choose the right compression method for various projects. Common codecs include H.264, ProRes, or DNxHD. This knowledge is important because it helps deliver high-quality videos that don't take up too much storage space and can play smoothly online.
