I heard about the complaint of the Nexus S' lack of 720p video recording? What does 720p mean? How does it compare to the standard Samsung Galaxy S phones?
720p is the shorthand name for a category of HDTV video modes having a resolution of 1280×720 (for a total of 0.92 megapixels or 921,600 pixels) and a progressive scan. The number 720 stands for the 720 horizontal scan lines of display resolution (also known as 720 pixels of vertical resolution), while the letter p stands for progressive scan or non-interlaced. When broadcast at 60 frames per second, 720p features the highest temporal (motion) resolution possible under the ATSC and DVB standards.
Its referring to the resolution that the video camera can record video in. 720p (1280×720 ) is a High Definition resolution. Apparently the maximum video resolution of the Nexus S is only 720x480 which is Standard Definition. Many new Android handsets have the ability to record HD video which is why it would be something to complain about with the Nexus S.
