Abstract
A method, system and article of manufacture is provided for processing a previously encoded MPEG video file for frame accurate timecode identification of each individual video frame. For each frame of the MPEG video file, the method creates a compressed timecode packet having an identifying signature, an absolute timecode of the frame, and a relative timecode of the frame, wherein the timecodes have the SMPTE timecode format HH:MM:SS:FF. Next, the MPEG video file is modified by inserting in a header of each frame of the MPEG video file the corresponding compressed timecode packet, while maintaining the MPEG video file's original frame presentation timing, thereby preserving the MPEG compliance and compressed audio/video data of the MPEG video file. The timecode packet is preferably automatically inserted in a user data packet of the frame, between the picture start header and the first slice header.
