Abstract
Some embodiments of the invention provide a novel method for processing a high definition (“HD”) digital video that includes video data and closed captioning data. The method (i) imports an HD digital video in a computer system, (ii) extracts closed captioning data from the HD digital video and (iii) stores the extracted closed captioning data in a storage of the computer system (e.g., hard drive of the computer system). Some embodiments first import all of the video before extracting closed captioning data from it, while other embodiments extract closed captioning data from the video as they import the video into the computer system. In some embodiments, a video editing application of a computer system performs this HD-video processing method. Accordingly, in some such cases, the method also edits the video that is extracted from the HD digital video. In addition, when video data is edited, the extracted closed captioning data is also edited in some embodiments.
