Visual effects (VFX) unite live-action footage with special computer images to create a special environment. The main techniques are covered in details by all reputed video editing courses in delhi.
This article discusses, in brief, some of the important VFX techniques prevalent in the industry. It also covers key VFX concepts. A good editing course can help you gain expertise in these techniques. The techniques are elaborated below:
- Chrome Keying
In Chrome keying, two images are layered together and a color range of the top layer is made transparent. The second layer thus becomes visible. Thus both the layers appear as one image. This technique is normally used in many videos and commercials. A good video editing course can help you practice this technique through practical sessions.
This is typically an animation technique. In rotoscoping a live video footage is converted to animation frame by frame. Animators take each frame and then trace lines, paint the frame with desired colors or apply certain animation effects for creating really like animation characters. An editing course teaches this technique through live demonstrations.
- Matte Painting
In matter painting, two or more images are combined to create a final single image. The foreground image could be the subject/actor and the background image is usually the desired backdrop/scene. This technique is very popular in films. Most of the editing courses cover this technique.
- Physical Simulation
This is a very popular technique used in a variety of movies these days. Physical simulation is used to create dynamic movements and simulations. This technique is used in movies to represent disaster events like floods, nuclear attack or any other form of destructive event.
- Motion Tracking
In motion tracking graphics and images are inserted into live action shots. Parameters such as the position of the image have to be taken care of while insertion. Motion tracking is a primary technique and is covered in details by most of the courses.
In morphing one image is substituted by another very smoothly and seamlessly. The transition is so smooth that it can’t be noticed with naked eyes. Morphing is often used in action films to create give slow-motion effect to an action shot. Morphing is a popular technique and therefore the good course imparts knowledge on this through workshops and practical sessions.
Apart from these visual effects includes many other techniques for e.g. 3D modeling, stop action, optical and makeup effects etc. Most of these techniques are used together to create a VFX presentation.
Some of the popular software applications used for VFX are 3DS Max, Adobe After Effects, Cinema 4D etc.
To learn VFX you should start right from the basics and then move on to the techniques. It is very important to have an eye for detail. A good editing course helps to gain knowledge through practical exposure and live projects.
