As we all know that High-definition video or HD video refers to a video system of higher resolution than standard-definition (SD) video, and most commonly involves display resolutions of 1280×720 pixels (720p) or 1920×1080 pixels (1080i/1080p). As there are more and more devices and equipment available for playing and recording HD videos, it has become the favorite video format for people to enjoy more wonderful video very soon. However, not all the software and devices can support this format, such as Windows Movie Maker; iPod, iPhone, Zune, Creative Zen; Youtube, myspace and other online video website. etc. Sometimes we still need a third party—[/b]HD Converter[/b] to overcome such inconvenience.
