Abstract
A method of providing file data for a converted video file from a file system. After receiving a request for a portion of file data from the converted video file, an existing video file from which to derive the file data is determined. A portion of file data from the existing file that corresponds to the requested portion of file data is then determined, and file data from the portion of file data from the existing file data, by converting the portion of file data to file data of a different quality. The generated file data is then returned.
