Abstract
The invention provides an editing system for editing and combining media material into a resulting media composition. The media may be film or video based material, and also may include audio material. The video may adhere to either NTSC or PAL timing. In response to editing instructions, an Edit Decision List (EDL) is produced that specifies the material that makes up the edited composition, and the order of presentation of this material in the output composition. The EDL specifies the input clips that are taken from the source material using source timecode and similarly defines the output order again according to a new time code, the record time code. The editing system produces an extended EDL that facilitates the downstream processing (after the editing has been completed) for post production tasks requiring the need to know accurately where edit points occur.
