Most of today's video footage is born digital, whether it's professionally recorded in a studio environment or captured on a smartphone. Compressed formats such as MPEG-4/AVC and HEVC are popular choices for storing video but these are inherently 'lossy' which means that some of the information in the original video is lost during compression. What effect does this have on the video image? How much information loss is acceptable? These are important questions when designing and specifying systems for archiving and retrieving visual images.

In this tutorial I will examine the factors that influence our perception of visual quality. I will explain how popular compressed formats can affect video fidelity and will introduce the concept of video quality measurement. Attendees will gain an understanding of how to assess and maximise visual quality when archiving and disseminating digital video.
