6.6.6 Setting Encoder Bitrate and FPS

The Dashcam tab allows specifying the encoder bitrate. Bitrate is specified in kb per second and can be
chosen freely within the range from 10 kbps to 40 Mbps. Encoder bitrate trades off video quality to the
compression speed and size of the video. For the Industrial DashCam 1 000 a value of 1 000 kbps is a good
combination of image quality and size of the created video file.
Further the desired framerate can be set by FPS slider. The maximum framerate is limited by the currently
selected area of interest. A smaller region enabled higher frame rates.
A recorded video file with a frame rate much higher than 100 fps is played so fast that no details can be
seen. The "Limit FPS in video file" switch bounds the frame rate resulting in a kind of slow motion when
playing the video file.

6.6.7 Setting Recording mode and video length

The Recording mode can be selected by positioning the "Video length" range sliders. The arrow in the mid-
dle represents the trigger point (↑). The two slider points are used to adjust the video length and how the
video is positioned around the trigger point. The left side represents the history part and the right the future
part. By knowing this, setting the right slider to the trigger point the history mode will be used. On the other
hand, setting the left slider to the trigger point future mode is used. When none is at the trigger point mixed
mode is used. A speech bubble that is indicating the time offset appears when clicking on the slider.
