Movie in the context of "Special effect"

Sheet music is a handwritten or printed form of musical notation that uses musical symbols to indicate the pitches, rhythms, or chords of a song or instrumental musical piece. Like its analogs – printed books or pamphlets in English, Arabic, or other languages – the medium of sheet music typically is paper (or, in earlier centuries, papyrus or parchment). However, access to musical notation since the 1980s has included the presentation of scores on computer screens and the development of scorewriter computer programs that can notate a song or piece electronically, and, in some cases, "play back" the notated music using a synthesizer or virtual instruments.

The use of the term sheet is intended to differentiate written or printed forms of music from sound recordings (on vinyl record, cassette, CD), radio or TV broadcasts or recorded live performances, which may capture film or video footage of the performance as well as the audio component. In everyday use, sheet music (or simply music) can refer to the print publication of commercial sheet music in conjunction with the release of a new film, TV show, record album, or other unique or popular event which involves music. The first printed sheet music made with a printing press was made in 1473.

A digital music store is a business that sells digital audio files of music recordings over the Internet. Customers gain ownership of a license to use the files, in contrast to a music streaming service, where they listen to recordings without gaining ownership. Customers pay either for each recording or on a subscription basis. Online music stores generally also offer partial streaming previews of songs, with some songs even available for full length listening. They typically show a picture of the album art or of the performer or band for each song. Some online music stores also sell recorded speech files, such as podcasts, and video files of movies.

A fan or fanatic, sometimes also termed an aficionado or enthusiast, is a person who exhibits strong interest or admiration for something or somebody, such as a celebrity, a sport, a sports team, a genre, a politician, a book, a television show, a movie, a video game or an entertainer. Collectively, the fans of a particular object or person constitute its fanbase or fandom. They may show their enthusiasm in a variety of ways, such as by promoting the object of their interest, being members of a related fan club, holding or participating in fan conventions or writing fan mail. They may also engage in creative activities ("fan labor") such as creating fanzines, writing fan fiction, making memes, drawing fan art, or developing fan games. Some excessively avid fans are called "stans" (a portmanteau of stalker and fan).

The term illusory motion, or motion illusion or apparent motion, refers to any optical illusion in which a static image appears to be moving due to the cognitive effects of interacting color contrasts, object shapes, and position. The stroboscopic animation effect is the most common type of illusory motion and is perceived when images are displayed in fast succession, as occurs in movies. The concept of illusory motion was allegedly first described by Aristotle.

Bilibili (stylized in all lowercase), nicknamed B Site (Chinese: B站, romanized: B zhàn), is a Chinese online video sharing website based in Shanghai where users can submit, view, and add overlaid commentary on videos.

Bilibili hosts videos on various themes, including anime, music, dance, science and technology, movies, drama, fashion, and video games, but it is also known for its extensive kuso-style parodies by subcultural content creators. Since the mid-2010s, Bilibili began to expand to a broader audience from its original niche market that focused on animation, comics, and games (ACG), and it has become a major Chinese over-the-top streaming platform serving videos on demand such as documentaries, variety shows, and other original programming.

Patrick Anthony Powers (October 8, 1869 – July 30, 1948) was an Irish-American producer who was involved in the movie and animation industry from the 1910s to 1930s. He established Powers' Cinephone Moving Picture Company, also known as Powers Picture Plays. His firm, Celebrity Productions, was the first distributor of Walt Disney's Mickey Mouse cartoons (1928–1929). After one year, Disney split with Powers, who started the animation studio Iwerks Studio with Disney's lead animator, Ub Iwerks.
