VFX is an essential aspect of todays modern day films. It is hard to imagine film companies not adding these effects to enhance our cinema experience.

I will talk you through what VFX is, how it is used in films and why many of us have become big fans of it.

Anything can be created, anything impractical that is impossible or difficult to film in live action, even a person

Different types of VFX

Computer-generated imagery – this type of VFX uses computer software such as Adobe After Effects to create animation and still visual effects. CGI is 3D computer graphics that are used in film, TV and gaming to create characters and environments. This type of VFX is used in advertising (motion graphics) and even virtual reality which gives us that amazing immersive experience.

Compositing – this is the final step that happens within the project. Compositing combines live action with visual effects. These elements are created separately however this process brings them together effortlessly to make it look as though they were created in one place. A green screen is used for filming this technique as it’s easier for compositors to edit in objects etc in post-production.

Motion capture – this type of VFX is all about the movement of the actor. An actor wears a motion-capture suit that has markers on various parts of the body. These markers are tracked by cameras that are then transferred onto the computer which is then generated into a 3D model using motion-capture software. Recording an actor’s facial expression is called performance capture. Markers are put on the actor’s face and tracked.
