How is a PowerPoint presentation to video conversion in HD format different from non HD format?

HD video means high-definition video which brings you a better picture and sound quality as compared to standard video. In HD quality, you get more lines of resolution as compared to standard video. The more lines of resolution you have, the sharper your video looks. 

High-definition starts at 720p (720 progressive lines of resolution) whereas standard-definition starts at 240p. A video created in 720p clearly is more crisp and sharp as compared to the one in 240p.
