Audio commentary - Wikipedia. An audio commentary is an additional audio track, usually digital, consisting of a lecture or comments by one or more speakers, that plays in real time with a video.

Commentaries can be serious or entertaining in nature, and can add information which otherwise would not be disclosed to audience members.[1]The DVD medium allows multiple audio tracks for each video program. DVD players usually allow these to be selected by the viewer from the main menu of the DVD or using the remote. These tracks will contain dialogue and sound of the movie, often with alternative tracks featuring different language dialogue, or various types of audio encoding (such as Dolby Digital, DTS or PCM). Among them may be at least one commentary track. There are several different types of commentary.

The two main types simply define the length of the commentary rather than the type of content. They are: Partial or scene- specific, which only covers selected scenes of the film. Sometimes these are recorded without the speaker viewing the film and thus the commentator may make more general comments than pointing out specific details. Feature- length or screen- specific, which is recorded in one session: the speakers watch the movie from beginning to end and give their thoughts directly based on what is happening on- screen. Typically a commentary track will include feature- length commentary from the film's director, cast members, or occasionally writers and producers.

Occasionally actors will perform commentary in- character. In recording sessions with multiple speakers, a designated moderator may encourage the discussion flow.) Some DVDs include outsider commentary performed by film critics, historians, scholars or fans. In more elaborate productions, multiple speakers from various recording sessions may be edited together for a single audio program. Some DVDs feature commentaries with on- screen video enhancements, such as telestrator prompts, (allowing the director or commentator to "draw" on the screen, pointing out specific details), or the Ghostbusters "video commentary", where one of the subtitle tracks is used to add silhouettes of the speakers in a manner where they seem to be in a theater commenting on the movie as it was screened for them in the style of Mystery Science Theater 3. Less common are actual video commentaries, showing the speakers as they are recording the commentary, requiring separate video tracks.

History[edit]The value of audio commentaries as a marketing tool was revealed during the heyday of laserdisc, the laser- based video format produced before the introduction of DVDs. The Criterion Collection company, for example, produced high- quality "deluxe" editions of classic films on laserdisc, using the best available prints and re- edited versions.

These were often very expensive compared to today's DVDs and included bonus material such as trailers, deleted scenes, production stills, behind- the- scenes information, and audio commentaries from the directors, producers, cast, cinematographers, editors, and production designers. They were marketed to movie professionals, fans and scholars who were seen as an elite niche of consumers who could afford to pay more for definitive, quality editions. The audio commentaries on laserdiscs were typically encoded on secondary analog tracks which had become redundant, as modern laserdiscs had stereo audio encoded digitally alongside. This is why certain older videodisc players, which pre- date the digital audio standard, are only able to play back analog tracks with audio commentary. The first audio commentary was featured on the Criterion Collection release of the original King Kong movie, on laserdisc in December 1. It featured film historian Ronald Haver and his first words were: Hello, ladies and gentlemen, I'm Ronald Haver, and I'm here to do something which we feel is rather unique. I'm going to take you on a lecture tour of King Kong as you watch the film.

The laserdisc technology offers us this opportunity and we feel it's rather unique — the ability to switch back and forth between the soundtrack and this lecture track.. The idea for the commentary track arose in the film- to- tape transfer room when laserdisc producers, Peter Crown and Jennifer Scanlin of Romulus Productions, Inc., thrilled by Haver's incredible commentary, suggested to Bob Stein and Roger Smith that this material needed to be included on the disc. They played back the completed movie as Ron watched and ad libbed his comments. The decline of the laserdisc format and the increasing popularity of DVD was highlighted in the fall of 1. DVD editions of the movie Contact were released. The former contained one bonus audio commentary track by director Robert Zemeckis, and producer Steve Starkey. However, the DVD contained two additional, separate audio commentaries (by Jodie Foster and the special effects producers), as well as other bonus features.

Despite its history with laserdiscs, the idea of audio commentary was still such an uncommon notion that, in its January 1. Contact DVD, Entertainment Weekly scoffed, "Who in the universe would want to journey through more than eight hours of gassy, how- we- filmed- the- nebulae trivia included in this "Special Edition" disc? Meant to show off DVD's enormous storage capacity, it only demonstrates its capacity to accommodate mountains of filler."[2]In general, directors are open to recording commentary tracks, as many feel it can be helpful to young filmmakers, or they simply want to explain their intention in making the film. Eli Roth, for example, specifically states on the producer's commentary track for The Last Exorcism, that he and the other filmmakers will offer advice to people interested in making films, as well as film school students.

He is a strong proponent of the educational use of audio commentary, having recorded five commentary tracks for his debut, Cabin Fever. He also recorded insightful commentary tracks, with Quentin Tarantino, for both Hostel films, in which the two horror movie fans share film- making anecdotes and offer advice on working in the movie business. Meanwhile, others (such as Steven Spielberg or David Lynch) feel commentary can de- mystify and cheapen a movie. Director Steven Spielberg has not recorded commentary tracks for any of his films. He feels that the experience of watching a film with anything other than his intended soundtrack detracts from what he has created. Woody Allen has a similar lack of enthusiasm for commentaries, stating, "I'm not interested in all that extra stuff.

I want my films to speak for themselves. And hopefully they do."[3]A number of movies released today feature audio commentaries. While many of them will not hold the interest of the casual viewer, specific releases stand out, mainly those with elements of historical interest or subject- specific information from expert advisors. For example, the inventor of the steadicam, featured throughout the audio commentary track for The Shining, discusses his work with the ground- breaking technology in several films leading up to that landmark production. Non- movie buffs may be interested in the anecdotes offered by advisors to the filmmakers, such as the FBI profiler commenting on The Silence of the Lambs (Criterion DVD release). Filmmakers and cast may reveal stories from behind the scenes, explain the process involved in their work, or simply offer additional laughs.
