Abstract

Disclosed is a method for copying a segment from an audiovisual file having a multiplicity of audio frames and a multiplicity of video frames. In a first step, a mark-in location in a video file is selected to correspond to a first video frame in the segment such that the first video frame has an associated start time. Next, a mark-out location in the video file is selected to correspond to a last video frame in the segment, and the last video frame having an associated end time. Once the mark-in video frame is selected, a first audio frame having a first audio frame start time that is at least as early as the first video frame start time is designated as an initial audio frame. A second audio frame having a second audio frame start time that is at least as late as the last video frame end time is designated as the last audio frame. The audiovisual file is copied to include a video portion extending from the first video frame to the last video frame and an audio portion extending from the initial audio frame to the last audio frame. In this manner, the audio portion of the segment may preferably be longer than the video portion of the copied segment.
