Why is it said that sync sounds are widely used in movies?

               Sync sound or synchronized sound recording means the recording of sound at the time of filming a movie.

               It is a technique used since the birth of sound movies. The first Indian talkie ‘Alam Ara’ released in 1931, used sync sounds. Following this trend, many other films too were shot using the same technique until the 1960s. 

 

               The 1960s saw the arrival of the practical, but noisy camera Arri 2C for outdoor shoots. After its introduction, sync sounds were not used, owing to the noisy environment it created. This in turn, popularized the technique of dubbing.

               However in recent times, many Indian films have adopted sync sounds. Some examples are films like Jodhaa Akbar, Lagaan, Dil Chahta Hai and Rock On.

               Although more effort needs to be put in, film-makers who go with sync sound say that the technique helps to breathe life into films. The challenge is to have a controlled environment while shooting.
