Visual effects in its most elementary structure are digitally controlled live action footage. Simply a visual effect is the ideal utilization of computers to insert and remove special effects or enhancements that wasn’t initially inside the shot. A visual effect is that the assimilation of live-action footage and generated imagination to make realistic environments. However formation of such fanciful would be critical, costly and basically difficult to capture on film. Jobs of visual effects employing computer-generated imagery (CGI) got to be continuously common in big-budget films, and have conjointly become open to the novice film producer with the presentation of economical animation and compositing applications. The article is must read for beginner filmmaker and visual effects artist interested in knowing common application and techniques for creating realistic visual effects.
Common Software Used for Creating Visual Effects (VFX)
3Ds Max is a 3D modeling, rendering and animation application. The application depends on computer 3D technology that meets expectation by making groups of “points” commonly known as vertices (who form surfaces when linked together). The image of three dimensions is made by modeling objects from assorted surfaces. Still pictures, films and video-game environments (besides other media) can be made with this technique.
Adobe After Effects
Adobe After Effects is the commonly used software for creating visual effects. Its essential uses include motion graphics (title introductions and logo movements) & compositing (including fake stuff into live footage). This program is incredible for fresher to visual effects. Its convenience and extensive variety of uses make it the ideal tool for Indy film making and small productions groups.
Boujou is a 3d motion tracking application that permits the insertion of computer graphics into real-life footage with right position, scale, introduction, and motion in respect to the physical information of the original footage. Also called matchmoving Boujou is like PFTrack and Syntheyes.
Maxon Cinema 4D
Cinema 4D is a 3D animation, modeling and rendering application. The application depends on computer 3D technology that meets expectation by making groups of “points” commonly known as vertices (who form surfaces when linked together). The image of three dimensions is made by modeling objects from assorted surfaces. Still pictures, films and video-game environments (besides other media) can be made with this technique. Cinema 4D applications are used on a professional level mainly for motion graphics. The software is easy to use and permits direct exporting into After Effects which additionally makes it preferred software amongst users of After Effects.
Autodesk Maya resembles like a special application for cg artists due to its “node base” framework. It has a strong ability about dynamics, particles, animation, modeling, rendering, etc. Maya is best if you utilize it all the time. However if you don’t use it regularly, you will need to “re-learn” it every time you lift it up. Maya encompasses some of the best features of animation.
Mocha software is mainly used for planar tracking & rotoscoping. The software comes along with tools for wire removal, lens distortion correction, clean plate generation & mesh warping, to convey an all-in-one VFX tool set. Mocha Pro is intended to supplement any editing, compositing and finishing environment, and offers computerized media artists an influential, instinctive and creative planar following based arrangement with a streamlined interface, accelerated work process and the ability to effectively manipulate and track shots impossible with customary solutions. It permits artists to effectively track shots where point trackers fail: shots with commotion, shots with motion blur and shots that go off-screen or are clouded. Mocha AE comes free along-with After Effects CS4 and above.
Nuke is primarily compositing software, similar to Adobe After Effects however utilized on a more specialized level. Nuke is one among the commonly used compositing software on big budget movies. Mainly professional VFX companies use Nuke and Flame. Nuke’s uses a node-based methodology which takes into consideration effective workflow inside a vfx group. Also it facilitate for integration of 3d models making it perfect for 3D compositing and environments. Nuke additionally permits for deep compositing which implies that users can work with ‘deep images’ containing numerous opacity or color samples per pixel. This permits rendering of CGI components without foreordained holdout mattes, avoiding the requirement for re-renders when substance changes.
PFTrack is a 3D motion tracking software that permits the insertion of computer graphics into real-life footage with appropriate positioning, scale, introduction, and motion in respect to the physical information of the original footage. Also called as matchmoving PFTrack is like Boujou and Syntheyes. PFTrack is likely the most refined instrument when in terms of the algorithms used. It supports object tracking, facial feature tracking (utlized for motion caputure). PFTrack 2011 being a node based application is easy to use for Flame and Nuke users to work with.
Syntheyes is a 3D motion tracking application that permits the insertion of computer illustrations into live-action footage with appropriate positioning, scale, introduction, and motion in respect to the physical information of the original footage. It is also called as match-moving Syntheyes is similar to Boujou and PFTrack. The application offers a complete high-end feature set, including stabilization, tracking, mesh building and motion capture.
Commonly used Visual Effects Techniques
Green screening is a technique for compositing (layering) two images or pictures together. A color range in the top layer is made straightforward, revealing an alternate image behind. Otherwise called known chroma keying technique, it is generally utilized as a part of video production and post-production.
Motion Tracking permits the insertion of computer graphics into live-action footage with right position, scale, introduction, and motion in respect to the captured objects in the shot. The term is utilized loosely to refer to several diverse ways of extracting motion information from a motion picture, especially camera movement. Motion tracking relates to photogrammetry and rotoscoping. It is often referred to as match moving.
A 3D model is a representation of any three-dimensional surface of article (either lifeless or living) by means of a 3d modeling software for example, 3Ds Max, Maya, or Cinema 4D. The product is known as 3D model. It can be shown as a two-dimensional image through a methodology called 3D rendering or utilized as a part of computer simulation of physical phenomena.
A matte painting as its name describes is painted representation of something like set, location, or landscape. It is very useful to create illusion of an environment that is impossible in real life and very expensive too for film makers and game developers.
Physical simulator software permits recreation or simulation of the way bodies of several types are influenced by a variety of physical stimuli. They are likewise used to make Dynamical simulations without needing to know anything about physics (material science). Physics engines are utilized throughout the video game and film industry. They are regularly utilized for high budget movies including natural disasters such as 2012.
Rotoscoping is the technique of physically modifying film or video footage frame by frame at a time. The frames can be painted on subjectively to make exclusively animated impacts like lightning or light-sabres, or followed to make realistic traditional style animation or to deliver hold-out mattes for compositing components in a scene and, all more recently, to create depth maps for stereo transformation.
