explain about video resolution
Answers
Video resolution in a display device refers to the number of distinct pixels that could be displayed in each dimension. It is usually quoted as width× height; for an example: “1024 × 768″. In this example 1024 indicates the width and 768 indicates the height that the display could be resolved in pixels. A display resolution is controlled by factors like the cathode ray tube and flat panel display which are presented in digital televisions and computer monitors.
In video resolution, the need to resolve more or less might occur. For example, while uploading a video in a computer to your mobile phone, you might have to reduce video resolution. Increasing video resolution does not have a very good impact since even though the video resolution is increased the quality does not necessarily improve, however, the size of the video file will definitely grow. Nevertheless, sometimes these transformations may be essential. If you want to burn a low-resolution video (for example a 320×240 video shot on your cell phone) to a DVD, you will need to increase the resolution because DVD standards require the video to have a resolution of at least 720×480
