3. Video Editing
• The process of editing:
 segments of motion video footage
 special effects
 sound recordings.
FILM=Videos + sounds + Effects

4. 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.

5. 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.

7. 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.

8. examples :
Original print
Final print

9. 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

10. example:
• from live action to animation

11. 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

12. 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.

13. Stop Action
example:

14. 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.

15. 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.
