RESOLUTION V. ASPECT RATIO:
Resolution is how the video world describes the number of
pixels (the tiny dots of color that make up an image) in each
dimension (height and width) of the image being displayed. If
the resolution of a video is written as 720x480, for example, this
means the images of the video are made up of rows containing
720 pixels across (from left to right) and columns containing
480 pixels from top to bottom.
In standard definition video, there are two different standards
for resolutions: NTSC and PAL. These standards originated in
the broadcast television days, so they naturally carried over
into the beginning of the digital video era. When applied to a
standard definition DVD, a NTSC video would have a resolution
of 720 x 480 pixels and a PAL video would have 720 x576
pixels. In both cases, the resulting aspect ratio could be 4:3 or
16:9... More on that later.
Digital video standards came together around the same time
as the rise of high definition television and video, so the old
PAL and NTSC systems were able to better synchronize their
standards. In high definition video, the standard resolutions are
720p (1280 x 720 pixels) and 1080p (1920 x 1080 pixels). In HD
video resolutions, the aspect ratio is 16:9, or widescreen.
