What Has Led to The Popularity of VFX Courses?
The VFX sector is set to experience a remarkable 29% surge, reaching a valuation of 180 billion Indian rupees by 2024. The surge is attributed to two factors.

Firstly, there is a noticeable rise in the production value or budgets of the film industry. Thanks to the growth of digital theatres, there is a greater opportunity for global distribution, enabling directors to undertake more ambitious projects.

Secondly, the industry is transcending beyond traditional film productions. Production companies and studios are incorporating VFX in various genres and content types.

These are the primary drivers of the growing demand for skilled VFX artists and, thus, the need for VFX courses.
