What are Visual Effects?
Visual Effects or VFX can be described as follows:
Making extra-ordinary things or environments which are not possible in REAL Life or way too expensive to build.
Now, these are not real like “Special Effects” which include actual physical things like BOMB BLASTS, BLOOD SPLASH, CAR CRASH etc. Going DEEP! Let’s see what we have in Visual Effects Menu:
You might have seen movies like Avengers, Justice League, Superman etc. and their “behind the scenes” footage. There you can see Big Blue or Green Screens. Let’s explain its purpose with following example:
As you can understand easily, it is used for Removing or Adding backgrounds in a shot. So… convenient right. You can simply shoot inside a cozy movie set and then change it to Himalayas later. This technique its widely used in Hollywood and other Movie industries around the World.
Another powerful Visual Effects technique. In this, we can arrange different Shots, Images, 3D Objects, Textures etc. one one other making it a Whole Big Picture. Consider the example below to understand it better.
Now, you know get it clearly that Composting is basically a Layered Arrangement of different Shots or Images to make one Single shot. After Effects will be the first priority of a beginner to learn composting. After that NUKE is also an outstanding software for Advanced Composting.
This technique helps where Green Screen fails or is not applicable. For example if you don’t want to change whole background but just a small thing like moustache from the face of an Actor, you will opt to Rotoscoping. Check this example to understand it better.
Simply, Rotoscopy is manual Green Screen Keying with the help of a graphics software. Digitally adding and removing things to shots is done by Roto(Nickname) too. There are different methods to do a clean and less time consuming Rotoscoping.
A well know VFX techinque used to track the moving things in a shot. You must have heard this term in Smartphone market, where Apps like Snapchat track your movements and put filters on your Face. In visual effects field, motion tracking is done in the following way.
Thus, it is easier to put an effect on moving objects or scene with motion tracking. Moreover, there are two types of tracking done, 2D (generally used for Vector Graphics) and 3D (used in VFX Industry).
Yes, Thanos is not real, niether do Groot. Hollywood is using Animated 3D characters frequently since 90s. The role of 3d objects is very simple in Visual Effects, to save money. You can cut the cost of building a Big Mehanical Dinosaur by replacing it with a 3D Dinosaur, that is way to easy to move.
There are endless uses of 3D Objects in VFX field, especially while learning 3D motion tracking. For designing purpose, Maya, 3Ds MAX, Cinema 4D etc. are few sofwares to make 3-D models.
These are the magic makers. From fairy dust to dragon fire everything comes under particle simulation. It is used on a large scale in Visual Effects Industry. In this, you create particles in a software and then add them to the shot. To simplify, look at this example.
It might look easy, but it is very difficult to make believable Particle Effects. As humans can easily distinguish between Natural and Computer generated particles. Particular by Red Giant is a nice choice to begin your particle effects training.
