The document discusses transcoding video files for both access and preservation purposes. Transcoding involves converting a video file from one format to another, such as converting a preservation master file to a smaller file that can be more easily streamed online for access. Transcoding can improve access by reducing file sizes and switching to popular codecs, while preservation transcoding focuses on migration to more efficient or supported codecs. The document provides examples of how various properties of a video file, such as frame size and rate, are manipulated during the transcoding process.
