Tutorial 4
Q3) Discuss several
considerations in shooting and editing video for multimedia. What techniques should
you use to produce the best possible video, at a reasonable cost? Which of the
techniques apply to all video, and which apply specific to multimedia?
There are many considerations
to keep in mind when setting up your production environment, depending on the
capabilities of your camcorder:Fast processor(s)Plenty of RAMComputer with FireWire (IEEE
1394 or i.Link) or USB connection and cablesFast and big hard disk(s)A second display to allow for

Shooting Platform
The shooting
platform must be steady. Using a tripod or even placing the camera on a stable
platform, such as a rolled-up sweater on the hood of a car, can improve a shot.
Try to use a camera with an electronic image stabilization feature for static if
you must shoot handheld.
StoryboardingPreplanning
a video project is a factor that cannot be ignored without costing time loss,
lots of unnecessary aggravation, and money that would be better spent
elsewhere. Successful video production, of any sort, deserves the time it takes
to make a plan to carry it out. Storyboards are like any sequential comic you
read daily. A storyboard can get everyone on one page quickly.LightingWith proper lighting, however,
it may be difficult for uninitiated viewers to differentiate between shots
taken with an expensive studio-grade video camera and an inexpensive camcorder.
Using a simple floodlight kit, or even just being sure that daylight illuminates
the room, can improve your image. Chroma KeysChroma keys allow you to
choose a colour or range of colours that become transparent, allowing the video
image to be seen “through” the computer image. This is the technology used by a
newscast’s weather person, who is shot against a blue background that is made
invisible when merged with the electronically generated image of the weather
map. The weatherman controls the computer part of the display with a small handheld
controller.
CompositionThe general rules for shooting
quality video for broadcast use also apply to multimedia. When shooting video
for playback in a small window, it is best
to avoid wide panoramic shots, as the sweeping majesty will be lost. Use
close-ups and medium shots, head-and-shoulders or even tighter. Depending upon
the compression algorithm used, consider also the amount of motion in the shot:
the more a scene changes from frame to frame, the more “delta” information
needs to be transferred from the computer’s memory to the screen. Keep the
camera still instead of panning and zooming; let the subject add the motion to
your shot, walking, turning, talking. Titles and
TextTitles and text are often used
to introduce a video and its content. They may also finish off a project and
provide credits accompanied by a sound track. Titles can be plain and simple,
or they can be storyboarded and highly designed. Nonlinear
Editing (NLE)Top-of-the-line nonlinear editing (NLE) software includes Adobe’s Premiere, Apple’s Final Cut, and
Avid’s Media Composer, the “A Team” of professional video editors. These are
feature-packed and expensive packages designed to work hand-in-hand with fast
and powerful computers and dedicated file servers.
