VHS-C to DVD transfer is based around the VHS-C tape, or "Video Home System-Compact." It was introduced by JVC in 1983 to take advantage of VHS's popularity, but provide a smaller alternative for the burgeoning consumer camcorder market. Fun fact: the first VHS-C camcorder model was used by Michael J. Fox in Back to the Future! (He used it to tape the event video of the DeLorean's first time-travel departure.)
JVC introduced its small VHS-C camcorder to compete with Sony's Betamovie, the first consumer camcorder. Some companies also released video cameras that used full-size VHS tapes, to compete with the longer running time of the Video8 tape.
The VHS-C cassette is 3 5/8" long, 2 1/4" wide, and 7/8" thick. The half-inch tape inside is the same width as a VHS tape. Inside, the magnetic tape is wound between a main spool and a take-up spool, with a geared wheel moving the tape forward. These wheels can also be moved by hand.
We convert VHS-C tapes using the famous VHS adapter shell, but we always flip each tape's protective cover open to check that it is intact first. The easy-to-use adapter shell is one big reason that VHS-C continued to be a popular video format as long as the VHS VCR was a main piece of electronics in most homes. As DVD players and digital video cameras arrived, VHS-C became an obsolete format.
The VHS-C format displays 250 lines of resolution on the television screen, and is thus the same quality level as VHS. This resolution stays intact when we transfer VHS-C.
