Sync sound
From Wikipedia, the free encyclopedia
Sync sound refers to sound recorded at the time of the filming of movies, and has been widely used in U.S. movies since the birth of sound movies. The first animated film in which sync sound was used is Walt Disney's Steamboat Willie. The characters and the boat dance in time with the music, and the gags are sound-related.
In Hong Kong, sync sound was not widely used until the 1990s, as the generally noisy environment and lower production budgets made such a method impractical.
