Sync sound

From Wikipedia, the free encyclopedia

Sync sound (synchronized sound recording) 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.

Most Bollywood films from the 60s onwards do not employ this technique and for that very reason the recent film Lagaan was noted for its use of Sync sound. The common practice in Bollywood is to 'dub' over the dialogues at the Post-Production Stage. Although the very first Indian talkie Alam Ara released in 1931 saw the very first use of Sync Sound in India, and since then Indian films were regularly shot in Sync Sound till the 60's with the silent Mitchell Camera, with the arrival of the Arri 2C, a noisy but more practical camera particularly for outdoor shoots, 'dubbing' became the norm and was never reversed.

Use of this technique has increased in recent times with development in film techniques and instrumentations like Arri Blimp camera.This system has been used in Hindi movie jodhaa akbar(2008).
