Digital Media Production Video Production

Video is the technology that captures moving images electronically.

Those moving images are really just a series of still images that change so fast that it looks like the image is moving.

o   Video is the technology of electronically capturing, recording, processing, storing, transmitting, and reconstructing a sequence of still images representing scenes in motion.

o   The term Video comes from the Latin word videre (to see) and describes sequences of moving pictures, which can be used to display on screen.

Video Terminology

*  Shot: A continuous piece of video or film footage. Everything you get between pressing "record" and "stop".

*  Framing and composition: subjects are framed and arranged within in your shots.

  Tilt

* Tilting is a cinematographic technique in which the camera is stationary and rotates in a vertical plane (or tilting plane).

*  A rotation in a horizontal plane is known as panning.

*  Tilting the camera results in a motion similar to someone nodding their head "yes" or to an aircraft performing a pitch rotation.

  Pan

*  Panning refers to the horizontal movement or rotation of a still or video camera, or the scanning of a subject horizontally on video or a display device.

*  Panning a camera results in a motion similar to that of someone shaking their head "no" or of an aircraft performing a pitch rotation. 

  Iris (exposure)

*  This is an adjustable opening (aperture), which controls the amount of light coming through the lens (ie. the "exposure").

*  The video camera iris works in basically the same way as a still camera iris, as you open the iris, more light comes in and the picture appears brighter.

*  The difference is that with video cameras, the picture in the viewfinder changes brightness as the iris is adjusted.

  White Balance

*  Process of removing unrealistic colour casts, so that objects which appear white in person are rendered white in your photo

*  Proper camera white balance has to take into account the "colour temperature" of a light source, which refers to the relative warmth or coolness of white light.

*  Our eyes are very good at judging what is white under different light sources, however digital cameras often have great difficulty with auto white balance (AWB). 

*  An incorrect WB can create unsightly blue, orange, or even green color casts, which are unrealistic and particularly damaging to portraits. 

Production

       Film production occurs in five stages:

1.    Development—The script is written and drafted into a workable blueprint for a film.

2.    Pre-production—Preparations are made for the shoot, in which cast and crew are hired, locations are selected, and sets are built.

3.    Production—The raw elements for the finished film are recorded.

4.    Post-Production—The film is edited; production sound (dialogue) is concurrently (but separately) edited, music tracks (and songs) are composed, performed and recorded; sound effects are designed and recorded; and any other computer-graphic 'visual' effects are digitally added, all sound elements are mixed into "stems" then the stems are mixed then married to picture and the film is fully completed ("locked").

5.    Sales and distribution—The film is screened for potential buyers (distributors), is picked up by a distributor and reaches its cinema and/or home media audience.

Non Linear Editing (NLE)

*  Non-linear editing (NLE) is a method that allows you to access any frame in a digital video clip regardless of sequence in the clip.

 

*  The freedom to access any frame, and use a cut-and-paste method, similar to the ease of cutting and pasting text in a word processor, and allows you to easily include fades, transitions, and other effects that cannot be achieved with linear editing.
