How to learn complete VFX Online || Complete RoadMap to Visual
Effects.
Creating VFX is not a very simple process and not a single process. Many different departments and people with specilization in each department are involved in this process of creating such huge vfx.
We will be discussing which are those processes , how to learn them , where to start , and important one which ones are not necessary at most times.
What are the various departments in VFX industry ?
1. Matchmoving
We will understand it very simply. Say you have a video footage and your camera is in motion during shooting the video. In this process the camera’s motion is tracked ,the software tries to understand how the actual camera has moved and collecting this data . You would be wondering that why is this necessary ? But it’s the most important process , It has various uses which we will discuss ahead in this Article . One of the use is to place 3d objects into the scene.

Main softwares uesd for Matchmoving are :
P F Track
3 D Equilizer
Syntheyes
2. Modelling
In this department 3D models are created so that they can be later animated and integrated into the scene. Most probably you must have seen Marvel Movies andyou are aware about superhero Hulk.
This creature was created in 3d inside computer using modelling software. 3D modelling does not only include creating 3D creatures but also means creating 3d environment. Best example would be the movie Avataar. In that movie the planes, the planet, the forests, the people, everthing was created in 3d using modelling.These models are also called as CGI (computer generated Imagery).
Hence 3D modelling is a crutial step in in VFX. Also this is useful for game development in order to create assests, game world etc.

Softwares used are :
Autodesk Maya
Autodesk 3ds Max
Blender
Cinema 4D
3. Animation
Let’s have the example of Hulk from Avengers movie. Since we created a 3d model of hulk but its can’t move on its own and its useless till now . In this process we first do rigging. Rigging means we make the inner skelton of model. We define its arms ,legs , head, etc.so that indivuial parts can be moved during animating it.
Then we animate the character accordingly . Suppose we want him to move forward so we make him move forward etc.
Here no specialized softwares are used. Animation process is done in the 3D softwares mention for modelling itself
4.FX
You must have seen destrutions involved in movies like buildings falling , fire ,smoke ground collapsing, ship went on fire,etc. All this is done by the fx department. Yes in 3d softwares using the 3d models . Later its integrted into the scene . Everthying is taken care of the lighting of scene , environment etc.
These are also done in the 3D softwares itself. The most popular are Austodesk Maya and Autodesk 3Ds Max.( To learn fx go here)
5.Rotoscopy
suppose we have a destruction fx or a 3D model which is to be integrated behind a person into the video . In these cases the person or the thing is cut out frame by frame through the video footage and then the fx or 3d thing is put behind him. There is also a term called roto paint . Roto paint is painting on a video frame by frame. Mostly used for processes like wire removal or removing any unwanted thing that came up in video during shooting it.
Software used for Rotoscopy is silluette fx. (To learn roto scopy go here :)
6. Compositing
This is the best part of all called composting. This Department is responsible for integrated all the above stuff into one and creating that masterpiece. In this the 3D models , Fx , Cg Environment all are mixed into the video scene. This is the end part of Vfx pipeline.
Most popular software used for compositing is Foundary Nuke. There are other softwares which are also used many a times like Fusion, After Effects. After Effects is also a popular software among vfx artists but its mostly used for 2D motion Design and vfx at small scale.
This was a rough Road map to get started into vfx. To Know more about different small scale proceeses involed in each of then check out the Blog. You will find a lot of information in this single Blog.
