In interlaced video, each field of a video image displays every other horizontal line of the complete image. The main benefit of interlaced video is that it allows more detailed images to be created than would otherwise be possible within a given amount of bandwidth -- in effect, interlacing allows a doubling of image resolution. Progressive video, on the other hand, is made up of consecutively displayed video frames that contain all of the horizontal lines that make up the image being shown. As a result, images appear smoother, fast-motion sequences are sharper and artifacts are much less prevalent. NRSEC can help determine the correct recording format for your companies bandwidth.
