Standard definition (less than 720p). Not much use anymore unless it’s for artistic purposes.
Standard definition (SD) refers to video resolutions that are below 720p (1280×720 pixels), typically around 480p (720×480 pixels). While SD was once the standard for broadcast television and home video, it has become less common in recent years as high-definition (HD) video has become more prevalent.
Today, most video content is shot and distributed in HD or higher resolutions, such as Full HD (1080p) or 4K (2160p). This is because higher resolutions offer greater detail, clarity, and color accuracy, and they can help to create a more immersive and engaging viewing experience for audiences.
However, there are some cases where SD video may still be used for artistic purposes. For example, some filmmakers and videographers may choose to shoot in SD to create a nostalgic or retro look, or to evoke a certain era or style of filmmaking. Additionally, some video games and other interactive media may still be designed to run at lower resolutions in order to ensure compatibility with older hardware or to create a specific aesthetic.
Overall, while SD video may no longer be as common as it once was, it still has some uses and applications in the world of video production and media.
