What is video resolution? Explain SD and HD video resolutions.

Question

Accepted Answer

Video resolution refers to the number of pixels that make up a video image on a screen, affecting its clarity, sharpness, and quality. SD (Standard Definition) has fewer pixels (e.g., 640x480), looks less sharp on large screens, but needs less storage and internet data, suitable for small screens and older devices. HD (High Definition) has more pixels (e.g., 1280x720 or 1920x1080 Full HD), giving sharper, clearer, and more colorful video, but requires more storage space and a faster internet connection.
