5.3 Other camera settings
Usually applications offer separate menu items for 'hardware' settings. These settings are not included in the
camera property pages themselves, and might be called different names in different applications. The most
important ones are Frame rate, Resolution and Format.
5.3.1 Frame rate (or Image rate, or something similar)
The frame rate setting determines the number of pictures per second in the video stream.
The set of frame rates from which the user can choose depends on the currently selected video format
(resoiution) and the available bandwidth on the USB bus (the number of devices connected to your USB port
and the amount of data they transport). To enable higher frame rates choose a smaller video image format in
your application. Applications will usually offer resolution switching (image format setting) under menu items
within the applications themselves. The maximum frame rate for VGA resolution (640 x 480) is 10 frames per
second
5.3.2 Resolution (or Size, or something similar)
Typically given in terms of pixels, this is used to describe overall video size. Related to quality in that the higher
the resolution, the better the quality and the more pixels. But more pixels and a high frame rate demand a lot of
bandwidth from your computer. So you have to compromise between frame rate and resolution for your
different applications if your computer lacks computing power.
5.3.3 Format (or Quality or Codec, or something similar)
This refers to a compression format for creating sound and video streams on the computer; a process for
compacting or squeezing video information into a smaller than normal size. For example, 2 to 1 compression
would indicate that 2 pixels would now only occupy the space of 1 pixel. Not all video applications use the
same formats (or codecs). It may be a source of error messages if your camera and the video application do
not use the same formats.
