When was 480p introduced

The reason is that not all pixels are square. Any image can be made up of any number or shape of pixels. When we watch most SD widescreen video like Fox Widescreen or video games which are only capable of displaying a certain number of pixels, they use square pixels so they can produce a 16x9 image. DVD players do this as well as video game consoles and cable boxes.

This is why they all these devices have settings which allow you to set the aspect ratio of your TV. If you turn it to widescreen even though you don't have a widescreen TV the image will be distorted. Some cable boxes will actually add black bars on either side so that the image is not distorted by the TV. The interesting thing is that DVDs are x which also isn't 16x9, but thanks to anamorphic abilities of your player, your TV scales the image to the native resolution of your TV.

Fox Widescreen has worked like this for years, Fox was the first to update their infrastructure to digital, but before HD was prevalent, as a result they were reluctant to go HD and ended up the last of the 4 major networks to go HD. More pixels in the image produces a sharper image.

If the image has more pixels, it is easy to see the details of the image even if you zoom in a lot. Usually, we use two numbers to represent the resolution. The number of pixels displayed horizontally x the number of pixels displayed vertically. For instance, now my screen resolution is x What resolution is p? The letter p represents a progressive scan, that is, non-interlaced scanning. An HD p Animoto video is crisp, sharp, and looks great on most displays.

For an even higher resolution, you can download your videos at p, another favorite for HD television stations. NOTE : p is available for download or sharing on social only. Once your video is the resolution you want, you can export it to YouTube, Facebook , Twitter , and more. You can also embed or share Animoto video links at up to p or download your video as an mp4 at up to p.
