What is VFX Visual Effects (abbreviated VFX) is the process by which imagery is created or manipulated outside the context of a live action shot in film making. Visual effects involve in the integration of live-action footage (special effects) and generated imagery (digital effects) to create environments which look realistic, but would be dangerous, expensive, impractical, time consuming or impossible to capture on film. Visual effects using computer-generated imagery (CGI) have recently become accessible to the independent filmmaker with the introduction of affordable and easy-to-use animation and compositing software.

Categories Visual effects primarily divides into two groups of:
ďƒ˜Special Effects: It covers any visual effects that take place in live action, e.g. on set explosions or stunt performances. ďƒ˜Digital Effects (commonly shortened to digital FX or FX): It covers the various processes by which imagery is created or manipulated with or from photographic assets. Digital Effects often involve the integration of still photography and computer-generated imagery (CGI) to create environments which look realistic but would be dangerous, costly, or impossible to capture in camera. FX is usually associated with the still photography world in contrast to visual effects which is associated with motion film production.

Digital FX also divides into different subgroups of professions such as: Matte paintings and stills: digital or traditional paintings or photographs which serve as background plates for 3D characters, particle effects, digital sets, backgrounds. Motion Capture (Mo-Cap for short): It’s the process of recording the movements of objects and or people. In a session of motion capture, the subject whose motion is being captured is recorded and sampled many times per second by different scanners placed all over the environment.

There are different types of systems that read the actor’s movement.
optical method that uses tracking cameras that lock onto specialized markers placed over the
actor’s motion capture suit. The other type of method is called the non-optical method where instead of capturing the markers location in space, it recorders and measures the inertia and mechanical motion in the area. Modeling: Creating 3D models of props or characters using specialized software. Animation: Assign movements for any objects and characters in 2D or 3D. Compositing: Combining visual elements from different sources to create the illusion that all those elements are parts of the same scene.
