Back to Top - What are some basic general shooting tips?
Get as close as you can to your subjects and shoot close-ups whenever possible.
For online video, avoid pans (horizontal movement of the camera) and zooms (focusing in or out using the zoom feature on the camera) because not only does it look bad on the Internet, but unnecessary movement also slows down the video stream.
Back to Top - How do I create quality sound?
Speak clearly, slowly and make sure there is limited background noise.
Have a simple script written ahead of time with the item description, price, year, make model any general information that a buyer and seller would exchange.
Back to Top - How important is lighting while shooting my video?
Turn On The Lights!
Camcorders typically have a difficult time recording video in darker areas. Camcorders will typically make video shot in dim areas look as though it was shot in complete darkness. If you have the ability to turn on more lights where you are, do it. the brighter the area you are recording the better
Back to Top - How do I create special effects?
Special effects are traditionally divided into the categories of optical effects and mechanical effects.
Optical effects (also called visual or photographic effects), are techniques in which images or film frames are created and manipulated for film and video. Optical effects are produced photographically, either "in-camera" using multiple exposure, mattes, or the Schüfftan process, or in post-production processes using an optical printer or video editing software. An optical effect might be used to place actors or sets against a different background, or make an animal appear to talk.
Mechanical effects (also called practical or physical effects), are usually accomplished during the live-action shooting. This includes the use of mechanized props, scenery and scale models, and pyrotechnics. Making a car appear to drive by itself, or blowing up a building are examples of mechanical effects. Mechanical effects are often incorporated into set design and makeup. For example, a set may be built with break-away doors or walls, or prosthetic makeup can be used to make an actor look like a monster.
Back to Top - How do I create a green screen using everyday items?
The process:
The principal subject is filmed or photographed against a background consisting of a single color or a relatively narrow range of colors, usually blue or green because these colors are considered to be the furthest away from skin tone. The portions of the video which match the preselected color are replaced by the alternate background video. This process is commonly known as "keying", "keying out" or simply a "key".
In analog color TV, color is represented by the phase of the chroma subcarrier relative to a reference oscillator. Chroma key is achieved by comparing the phase of the video to the phase corresponding to the preselected color. In-phase portions of the video are replaced by the alternate background video.
Clothing:
A chroma key subject must not wear clothing similar in color to the chroma key color(s) (unless intentional), because the clothing may be replaced with the background video. An example of intentional use of this is when an actor wears a blue covering over a part of their body to make it invisible in the final shot.
Background:
Blue is generally used for both weather maps and special effects because it is complementary to human skin tone. However, in many instances, green has become the favored color because digital cameras retain more detail in the green channel and it requires less light than blue. Green not only has a higher luminance value than blue but also in early digital formats the green channel was sampled twice as often as the blue, making it easier to work with. The choice of color is up to the effects artists and the needs of the specific shot. In the past decade, the use of green has become dominant in film special effects. Also, the green background is favored over blue for outdoors filming where the blue sky might appear in the frame and could accidentally be replaced in the process. Although green and blue are the most common, any color can be used. Red is usually avoided due to its prevalence in normal human skin pigments, but can be often used for objects and scenes which do not involve people. Occasionally, a magenta background is used.
With better imaging and hardware, many companies are avoiding the confusion often experienced by weather presenters, who must otherwise watch themselves on a monitor to see the image shown behind them, by lightly projecting a copy of the background image onto the blue/green screen. This allows the presenter to accurately point and look at the map without referring to monitors
Even lighting:
The biggest challenge when setting up a bluescreen or greenscreen is even lighting and the avoidance of shadow, because it is best to have as narrow a color range as possible being replaced. A shadow would present itself as a darker color to the camera and might not register for replacement. This can sometimes be seen in low-budget or live broadcasts where the errors cannot be manually repaired. The material being used affects the quality and ease of having it evenly lit. Materials which are shiny will be far less successful than those that are not. A shiny surface will have areas that reflect the lights making them appear pale, while other areas may be darkened. A matte surface will diffuse the reflected light and have a more even color range. In order to get the cleanest key from shooting green screen it is necessary to create a value difference between your subject and your green screen. In order to differentiate the subject and screen use a two stop difference either by making the green screen two stops higher than the subject or visa versa.
Back to Top - How do I create camera movement to make a more interesting video?
This is one of the most critical elements in making your video. Slow, even movement of the camcorder creates interest in the final video; whereby shaking or quick camera moments will translate into a blurred, out of focus video.

Back to Top - What do I need to be aware of about email spam, spoofs and phishing?
In computing, phishing is an attempt to criminally and fraudulently acquire sensitive information, such as usernames, passwords and credit card details, by masquerading as a trustworthy entity in an electronic communication.
