Step 1: Record ABC Evening News, October 24, 1997

The project presented here skips the most difficult step for an amateur videographer, the creation of video footage. Camcorders are easy to use, in the same sense that word processing software is easy to use. But few of us can create the instructional equivalent of a good novel or a good movie. In this case, the video footage was created by the large and talented staff of ABC News.

Step 2: Convert analog VHS video to digital video

If the video footage had been created using a miniDV camcorder, the IEEE1394 output of the camcorder would have been connected to the IEEE1394 input of the PC. The camcorder would have been placed in Play mode, and the transfer of the already digital video signal to the computer would have been done under the control of video capture software. Because the ABC News footage is on analog VHS tape, the procedure here requires a device that will convert the analog signal to digital. The device I used and recommend is the ADVC-100 Advanced DV Converter from Canopus, which costs $270. The ADVC-100 converts VHS and sVHS analog video to miniDV using its own custom hardware Codec chip instead of using software and the processing power of the PC. The output of the ADVC-100 is already miniDV video, which gets connected to the IEEE1394 port of the PC. The only significant difference between the output of the ADVC-100 and that of a miniDV camcorder is that the capture software cannot start and stop the playing of the VCR; you’ll have to manually start and stop your captures. Therefore, I started capture slightly before the point that would become the start of my video clip and ended capture slightly after the point that would become the end of my clip. Then I used the editing software to trim the clip, as described below.

When using a VCR connected to the ADVC-100, you will not need a TV to look at the playing tape, because the capture software will display it in a window on the computer monitor screen.
