With the recent released blockbuster Kal Ho Na Ho doing a great business, Visual Computing Labs (VCL) seems to be rubbing its palms in glee. Reason, VCL has executed the visual effects of the appealing Bollywood venture.

The Tata Elxsi Limited's branch used VFX focus on look-n-feel, aesthetic appearance of the film.

VCL offers content creation, animation and special effects services to both Hollywood as well as Bollywood, says a company release.

According to the VCL head K Chandrashekhar, "The challenge with Kal Ho Na Ho was in creating special effects that go beyond the conventional treatment used in tricks, stunts and action sequences. The emphasis of the VFX was towards working on the look-n-feel, design and thus enhance the viewers experience on the film's aesthetic appearance. We achieved this using our rich expertise and our in-house optimization techniques. The effects are not felt visibly as these were used to enable storytelling in an effective manner, and this was the biggest compliment for us."

VCL has delivered about 40 minutes of special effects on Karan Johar's Kal Ho Na Ho - a mega blockbuster venture that revolves around the power of friendship. An emotional love story starring Jaya Bachchan, Shah Rukh Khan, Preity Zinta and Saif Ali Khan was released on 28 November 2003.

Directorial venture of Nikhil Advani, the film it is packaged with some stunning visual effects that have been choreographed by the VCL team at Mumbai, under creative director Pankaj Khandpur's eye.

The special effects comprise primary and secondary colour correction, and chroma-key corrections, which has been used on the introduction of each character in the movie, to replace backgrounds, says the release. Other methods used in the film include time warp techniques, transitional sequences, costume replacement and time devices used during narratives, where two activities are incorporated in the same shot simultaneously.

Besides Kal Ho Na Ho, VCL has successfully delivered VFX and animation effects for various Indian and Hollywood films from its Bangalore and Mumbai labs and undertakes TV series, ad films, animatics and games development projects.
