On the following window the video capture parameters can be set. These values can be left at default settings but the
user has the options to modify these values.
The bitrate can be increased if the computer’s USB bandwidth is fast
enough to handle it. The quality setting determines the degree of data compression. If quality is set at 100 then the
images are captured at the highest quality resulting in larger video files on the disk.
The
Key Frames Setting
determines how frequently video frames are shown on the monitor while video is being
captured on the hard disk. If this value is set too high, then the captured video will be slow and jerky. In the final
window it is possible to enter information to identify the video to be captured.
Exposure Time
In astronomy, the exposure time should be selected manually from pull down menu (
H
) on the left panel. Un-tick the
Auto Exposure
option and set the exposure time from the sliding bar or by clicking on the time and typing the
exposure time manually in milliseconds.
