vfx video If you love movies, you must have heard about the technology.
Well, film aside, today VFX is used in everything from advertising, video games to making YouTube videos.
Now the question arises: What is VFX and how is it used?
VFX stands for visual effects And with this technology, things are shown on the screen that are not actually there.
Visual effects are used to add interest to any video or create impossible scenes.
For example, VFX has been widely used in popular Hollywood films Titanic or Jurassic Park and Indian films Bahubali, RRR or Robot.
Tell us more about this technology.
What is VFX? What does VFX mean in Hindi?
Before knowing more about this technique, let’s see what is the complete form of VFX?
Full form of VFX – Visual effects (visual effects,
Meaning of VFX in Hindi – visual effects
This means that with VFX technology, we can get the effect we want to show in any scene where it would be too dangerous, difficult or impossible to shoot live.
In the above Baahubali video, you can clearly see how the VFX artists painstakingly create things that don’t actually exist.
Using VFX technology, it is possible to create environments, objects, creatures and even people that are almost impossible to render on screen.
Visual effects are created by combining real film footage with simulated or animated images, which then appear to resemble the original.
Using this technique is much cheaper, time saving and easy and safe than shooting the actual scene.
Apart from VFX, you must have heard of SFX too, but do you know the difference between the two?
What is SFX? What is the difference between SFX and VFX?
sfx Of full form It happens Special effects And it’s different from VFX.
While VFX are added during post-production editing using computer software, SFX, or special effects, are used only during video shooting.
VFX – for example, the crowd and stadium that will be added later for the TV commercial shown above
SFX – It is used in a real-time set, such as fake rain, controlled explosions, gunshots, wounds or fake makeup.
vfx How is it used? How does VFX work in Hindi?
Now you may be wondering how VFX artists, producers and editors achieve these amazing effects?
Visual effects can be used in one or more of the following ways:-
- chrome key
- motion capture
Let us know what they are!
1. What is CGI?
cgi Of full form It happens Computer generated images and his Hindi meaning This a fictional computer-generated scene ,
In the world of film and television, CGI is used to implement digitally generated VFX.
It is a type of computer graphics, also called 3D VFX or 3D modeling, in which a 3D model of any object, surface, living or imaginary creature is created.
In addition to creating huge castles, dragons, monsters, etc., CGI VFX is also used to create subtle things like filling a stadium to make an actor look younger or older, or showing hundreds of soldiers in battle.
Today, CGI is widely used because it is generally cheaper than traditional methods.
For example, nowadays there is no need to hire extras during filming, from creating physical models of objects to crowd scenes.
2. Compositing Chroma-key What is green screen video?
Now imagine that 3D models are made from CGI for a fantasy scene and now need to add them to the main scene, then how is this done?
Composition or chroma keying is a technique in which different scenes are combined into a frame in such a way that they appear to be in the same place.
For this, a green screen or a blue screen is used as a background, which is then replaced by what needs to be displayed using software.
In the past, matte painting was used to show some amazing scenery in the background or something like that, but nowadays the same thing is done qualitatively using CGI.
Apart from movies, nowadays people are also making green screen videos for YouTube where the desired background can be added later using editing software.
Now you can ask –
Why is only green screen used in background VFX?
Green screen is used in background VFX because:-
- The green color does not match the natural skin tone or hair color, which makes it easier to remove the background during editing.
- Removing the background using any other colored veil will greatly affect the face of the actor/actress.
- If the actor/actress’s clothes are green, a blue screen is used.
3. What is motion capture?
Motion capture is a technique where the movements of an actor/actress are digitally recorded and then transferred to a 3D model.
With its help, phrases can be created in numerical or imaginary characters.
In this, the actor wears a motion capture suit with special markers that the video camera can track.
To measure facial expressions, sometimes marker points are placed on the face and the camera follows it.
After that, the data from the camera is placed into a 3D model using motion capture software.
In addition to movies, motion capture technology is also used in the medical and robotics fields.
