Conventional shooting has obvious limitations in conveying a message clearly and effectively. Therefore, when extraordinary effects, fictitious characters and environments are needed to be displayed; animation is the only available option. Being an expensive option, animation is usually adopted when other options are unable to achieve the desired objectives

When filming, animation, VFX and sound are done, the challenge is to combine them together in a way as to enhance the quality and improve the aesthetics of the message. Post involves colour treatment, image processing, motion graphics, compositing, editing, etc.
