Chennai Express - "Titli" - Interesting Song Making
The song is shot in high-speed - in this case they needed to shoot it at higher frame rate and then play it in lower frame rate to give it a slow motion effect. If you don't have to do lip-sync or speech scene then it's not much problem like filming action shots or running scenes or some other stuff. But this is a song in which you needed to do lip-sync and if they filmed it while playing a song in its normal speed. The outcome would've been just crap, audio wise, cause they wouldn't be able to sync the audio with the video. So to shoot this they played song at high speed, and when you play it fast the pitch gets changed and it sounds funny like a chipmunk song as Rohit Said in this video.
