Abstract: Some embodiments provide a method for automatically identifying settings of a media file. The method initially receives the identification of a piece of media content. Media content includes sound and image data that can be stored as a media file. It then performs an automated process for discovering the media settings of the media file. Examples of settings that are automatically identified in some embodiments include video codec type, audio codec type, frame height and frame width, video bit rate, video frame rate, audio channels, etc. The method then stores the media settings that are discovered from the media file. The stored media settings are used subsequently in some embodiments to generate a media file.
