Abstract

Background There are worldwide a very large number of analog videotapes. These tapes may be in old formats (reel-to-reel), they may be gradually deteriorating, and they may be hard to access because of the inherent sequential nature of tape. Digitizing these tapes solves all these problems. However, if these tapes have timecodes, these may or may not be carried forward when they are digitized. Tape may or may not have time codes. Digitizer may or may not be able to read time codes. Digitizer may be able to read time codes, but person digitizing elects not to transfer the timecodes to the digitized file or elects a format for the digitized file that cannot hold time codes.
