What is 480i vs 480p?

480i and 480p are both standard-definition video formats used in older televisions.

480i stands for "480 interlaced lines" and is a format where every frame of video is split into two fields, alternating between odd and even scan lines. This means that the image on the screen is actually being painted in two passes, which can result in motion blur or flicker.

480p stands for "480 progressive lines" and is a format where every frame of video is displayed progressively, or all at once. This results in a smoother and clearer image with less motion blur or flicker.

In general, 480p is considered superior to 480i because it provides a better image quality. However, some older televisions may not be able to display 480p and can only receive a 480i signal.
