This lesson will present a few basics for using a video camera to record a scene for inclusion in a multimedia presentation.
|We will be using a Panasonic camcorder (analog) and a Sony Handicam (digital) . Take the time to become familiar with their basic operation before you begin shooting.|
Following a few simple rules when filming for desktop video will improve the quality of the shot:
Video creates large files, so avoid occupying screen area with unnecessary background. Stable backgrounds compress better than moving backgrounds, so try to avoid any camera motion. Moving the camera or changing the frame in any way (zooming in or out) makes file compression more difficult because it generates a greater difference between video frames.
Sound is actually harder to do well than images, so don't underestimate the attention that you need to devote to getting a good sound track. The environment is full of sounds. Human hearing is all about filtering out the things that are not important and paying attention only to the important details of what we hear. In a recording, we can hear all of the noises that we normally do not notice because our perception filters them out. Make sure that the sound track includes only the sounds that you want.
The larger the screen, the easier it is to see facial features and the
more screen area may be occupied by background. Cinema, television,
and computer screen video formats must take relative size into consideration
when determining the best framing for
the subject. Which of the following frames is a better choice for
your online digital video?
In our previous lesson on video capture, we looked at using Adobe Premiere
to capture a video.
|There are numerous tools that allow us to capture video.
Some video cards have a built-in video capture function, there are video
capture devices that connect to a computer through a USB or Firewire connector,
one might have a separate card that only does video capture, or a digital
video camera might transfer the digital video as a file directly to your
The photo at the right shows the interface for capturing video using the Matrox Marvel G400 video card. This card is designed to capture video in MPG format, so that is the CODEC (compression / decompression algorithm) that we would use with this device. Once the video is captured, we use video editing software to make any changes needed. Because there are so many different tools on the market, and because they behave so differently, it is necessary to follow the directions that come with the software and hardware that you have purchased.
