For a widescreen movie with a common aspect ratio of 2.35:1, 560p typically results in a frame size of roughly pixels after letterboxing. For 16:9 content, it’s about 560 × 315 pixels. In raw numbers, that’s approximately 0.3 megapixels per frame.
In the early days of digital file sharing, 560p was sometimes used by encoders to provide a "pseudo-HD" experience. It allowed for a perceived quality boost on smaller monitors without the massive file size of 720p.
