Abstract
Disclosed is a method for clipping a segment from a video file having a multiplicity of video frames. Preferably, at least some of the frames in the video file are encoded as predicted frames. The method includes selecting a mark-in location in the video file that defines the beginning of the clipped segment. A mark-out location defining the end of the clipped segment is also selected in the video file. Once the mark-in and mark-out locations are selected, the method decodes a first frame associated with one of the mark-in location and the mark-out location. The first frame is preferably a predictive frame that has an associated first format. The first frame is then re-encoded into a second format and stored. The method then proceeds to create a clipped segment that includes the re-encoded first frame.
