VFX (Visual Effects) in Nepal -A Quick Beginner’s Guide
VFX is exciting, right
Yes. Indeed. It is.
VFX is important today more than anytime before.VFX is applied today in film industries almost all over the world. People love to see something that they can’t see off the camera
All movies have to be dramatic. And, visual effects help a lot in these scenarios. Before we dive into different aspects of VFX, let’s take a moment to get back to the basics.
What is VFX?
VFX is about manipulating the scenes outside the context of a live action shot.Let’s make it simple.
Often times, there are situations when we cannot shoot something in live action.For example, the city destruction.We can’t destroy the city for 1 movie.That’s the reason the imagery for this kind of situation is manipulated or even created through softwares in post-production.Most people confuse visual effects with special effects.Special effects are visual effects that take place in live action. As some would imagine – for example – set explosions.However, VFX can be much broad.In fact, most of the works from Visual effects would go unnoticed.
Aspects of Visual Effects
Here are few important aspects of visual effects:
It is quite simple.The composition is bringing images and footages from various sources to organize them into one scene.This creates an illusion to the viewers that everything belongs to one scene.Often we see the backgrounds removed and replaced with a new one.These are typically scenes shot with “Green Screen” background and replaced with a new appealing background.
Motion Capture / Tracking
It’s a process of recording the object’s motion – as the name suggests.Objects might sometimes be people.VFX artists replicate and apply the camera movement from the shot to the elements that were not there in the shot.They track points in the footage using tracking points.If a scene is composited well and tracked well, you should not be able to say that it’s fake.
When you manually cut out something frame by frame.Rotoscoping is an act of tracing an object in film or video to be able to add or remove that object.Remember the first time you used Photoshop.You probably cut yourself into a different layer and changed the background or something.Rotoscoping is the same.It’s almost the same technique, however in the video.
As mentioned in the composition section, it’s using green screens or blue screens in the background.You need to use colors that are not there in the composition.Basically, you want keying to remove or replace something in the background.You want to see everything but that color.Green Screen keying is one of the favorites among filmmakers.
Matte Paintings have been there for a very long time.Simply, it is a painted representation of a landscape or anything used to create an environment that’s not there in live action.
