Many processing tasks produce images. When Media Server ingests video, it decodes the video into individual frames. Analysis tasks can also produce images, for example keyframe extraction, face detection, and number plate recognition produce images of keyframes, faces, and number plates, respectively.
You might want to resize these images before encoding them. For example, you might extract keyframes for use in a web application, so that your users can navigate through a video file. In this case you might prefer to have thumbnail-size images rather than the high-definition video frames.
This section describes how to resize images in Media Server metadata tracks.
