HD Video, or High Definition Video, refers to video quality that is significantly higher than standard definition. It typically has a resolution of 720p (1280x720 pixels) or higher, with 1080p (1920x1080 pixels) being the most common format. This increased resolution allows for clearer, sharper images and more detail, making it ideal for watching movies, sports, and other visual content. The technology behind HD Video has evolved over the years, leading to the development of even higher resolutions like 4K and 8K. These formats provide even greater detail and clarity, enhancing the viewing experience on larger screens. HD Video is widely used in various platforms, including television, streaming services, and video games.
