30 lines per frame

"30 lines per frame" refers to the amount of visual information displayed on a screen during one complete picture cycle, called a frame. In video or television, each frame is made up of many horizontal lines of pixels. At a rate of 30 lines per frame, the display shows 30 horizontal lines of detail for each image. This setting affects the resolution and clarity of the picture; higher lines per frame generally produce sharper images. It's a technical detail that impacts how smooth and detailed the video looks, especially during motion. This standard was common in older television systems and continues to influence display and video processing.
