Video Editing
• The process of editing: segments of motion video footage special effects
sound recordings.
FILM=Videos + sounds + Effects
What is VFX ? :
a category of special effects in which images or film frames are created and manipulated for film and video.
integration of live-action footage with computer generated imagery.
Types Of VFX : Visual effects may be divided into at least four
categories: Models: miniature sets and models, animatronics, stop
motion animation. Matte paintings and stills: digital or traditional
paintings or photographs which serve as background plates for keyed or rotoscoped elements.
Live-Action Effects: keying actors or models through bluescreening and greenscreening.
Digital animation : computer graphics lighting, texturing ,and rendering computer-generated 3d characters, praticle effect, digital sets, background.

Optical effects
Chroma Keying It is a technique for compositing two images or frames
together in which a color image is removed (transparent) revealing another image behind it.
It is commonly used for weather forecast broadcasts.
This technique is also used in the entertainment industry.
The color image is generally a green or blue colored clothing.
examples :
Original print
Final print
Rotoscoping
It is an animation technique in which animators trace over live-action film movement, frame by frame, for use in animated films
The technique was invented by MaxFleischer
example:
• from live action to animation
Morphing• It is a special effect in motion pictures and
animations that changes (or morphs) one image into another through a seamless transition.
• examples:
image Of George.W.Bush & Hollywood
Actor Arnold Schwarzenegar
Stop Action• Stop Action Also known as stop action is an
animation technique to make a physically manipulated object appear to move on its own. The object is moved in small increments between individually photographed frames, creating the illusion of movement when the series of frames is played as a continuous sequence. Clay figures are often used in stop motion for their ease of repositioning. Motion animation using clay is called clay animation or clay-motion.

Challenges for VFX :
We will able to build virtual human.
We will able to create believable facial animation.
We will able to create synthetic massive environments.
Pipeline tools will be standardized.
Advances in digital VFX animation will mean far less physical effects work.
Movie/game conversion will become common.
Detriments of VFX Specific hardware and special programs are required to
obtain and process the data.
The cost of the software, equipment and personnel required can potentially be prohibitive for small productions.
Movement that does not follow the laws of physics
generally cannot be captured.
If the computer model has different proportions from the capture subject, artifacts may occur.
