Converting a video from a lower resolution like 480p to a higher resolution such as 1080p involves a process called upscaling. This process increases the number of pixels in the video frame. For example, a 480p video has 640×480 pixels, while a 1080p video has 1920×1080 pixels. Upscaling algorithms attempt to fill in the missing pixel data to create a larger, more detailed image.
The importance of increasing video resolution lies in improved viewing experience, particularly on larger screens. Higher resolution videos appear sharper and more detailed, reducing pixelation and blurriness. Historically, the ability to upscale videos has become increasingly relevant as display technology has advanced, with larger screens and higher resolutions becoming more common. It is important to note that upscaling cannot restore detail that was not originally present in the source video; it can only attempt to approximate it.
