In filmmaking, behind-the-scenes (BTS), also known as the making-of, the set, or on the set, is a documentary film that features the production of a film or television program. This is often referred to as the EPK (electronic press kit) video, due to its main usage as a promotional tool, either concurrent with theatrical release or as a bonus feature for the film's DVD or Blu-ray release.

A blooper, or gag reel, is a short clip from a film, television program or video production, usually a deleted scene, which includes a mistake made by a member of the cast or crew. It also refers to an error made during a live radio or TV broadcast or news report, usually in terms of misspoken words or technical errors.

scene that is removed from a film before release

An outtake is a portion of a work (usually a film or music recording) that is removed in the editing process and not included in the work's final, publicly released version. In the digital era, significant outtakes have been appended to CD and DVD reissues of many albums and films as bonus tracks or features, in film often, but not always, for the sake of humor. In terms of photos, an outtake may also mean the ones which are not released in the original set of photos (i.e. photo shoots and digitals).
