Some early releases were time-compressed in order to save tape time and money and to compensate for long-playing cassettes being unavailable in the early days of home video. One example was 1978's Superman in which the film was released in a 127-minute format, compared to its 143-minute theatrical release. In addition, early film-to-video transfers of films from WCI were noted for being in poor quality, compared to modern day video releases. By the end of 1980, the quality of transfers had improved. The company was noted in its early days for releases in big cardboard boxes, that opened like a book, colored in Black, with cast credits on the inside. Some early releases under the Warner Home Video name also used this design. In early 1981, the company switched to plastic clamshell cases, with a multicolor design, with a few releases using the cardboard boxes and the multicolor designs, and to cardboard sleeves in 1985 for packaging, eliminating plastic cases by 1986. In the late 1990s, the studio revived the use of plastic cases for a handful of releases from Warner Bros. Family Entertainment. Warner Bros. began to branch out into the videodisc market, licensing titles to MCA DiscoVision and RCA's SelectaVision videodisc formats, allowing both companies to market and distribute the films under their labels. By 1985, Warner was releasing material under their own label in both formats. Titles from Warner Home Video were and continue to be distributed and manufactured by Roadshow Entertainment in Australia and New Zealand because of its film counterpart's films released by Village Roadshow. Rentals Warner also experimented with the "rental-only" market for videos, a method also used by 20th Century Fox for their first release of Star Wars in 1982. Two known films released in this manner were Superman II and Excalibur. Other films released for rental use include Dirty Harry, The Enforcer, Prince of the City, and Sharky's Machine.
