Abstract
The present invention provides a video editing system that provides dynamic synchronization of recorded video elements of a presentation with a script text that is to be read by an announcer or displayed while the video element is played. The editing system includes a word processor whereby the script text may be created and edited in a text window on the editing system display. Raw video clips, from video sources connected to the editing system, may be selected and previewed in a video window on the editing system display. Selected video clips are linked to the script text by embedding edit link control sequences into the text at selected points. The control sequences in the script text are linked through a link table to edits in an edit decision list (EDL) that define the video clips that are to be synchronized to the script text. A text scanning routine scans the script text and updates the EDL to reflect changes to the script text to maintain synchronization between the script text and linked video clip segments. A completed program may be viewed on the editing system display in a manner showing the synchronization between the video program elements and the script text. The edi…
