Motion Tab
The options are:
• Frames per second - This pulldown menu is used to specify the frames per second
that the robot should use when capturing video. The available values are 1, 2, 5, 10,
15 or 30 frames per second.
• Video Compression - These parameters are used to specify the type of compression
to use as well as the parameters associated with the compression type selected. Be
sure to consider your needs and the type of camera you are using when selecting
values.
• Type - This pulldown menu is used to select the type of video compression to
use. The default value is none.
• Data rate - If the compression algorithm that you selected supports this
parameter, select the checkbox. The range of values depends on the compression
method chosen, the frame rate, the quality and the key frame rate. Pick a
reasonable value to correspond to your other settings, should you choose to set
this value manually.
• Quality - If the compression algorithm that you selected supports this
parameter, you can specify the percent of the optimal possible quality at which
to save the video file. Specifying a higher value will yield higher resolution, but
also larger file size. Selecting a smaller value will yield lower resolution, but a
smaller file size. The file size should be considered when emailing video files.
The default value is 85%.
• Key frame spacing - To select this parameter, select the checkbox and specify a
value. If you want to be able to scan quickly through your video, you will want
keyframes, which do not depend on previous frames for determining what is in
them. The first frame is always a key frame, since it can not depend on any other
frames. If you had no other key frames, and you wanted to start watching the
video from the middle, the system would have to decompress all the
intermediate frames to determine what was in the middle frame. If you have
keyframes, say every 10 frames, it would have to decode at most 10 frames to
determine what was in that section of video.
• Add a sequence number to each video - Use this parameter to append a number on
the end of a file name, before the file type extension. This parameter helps to create
unique filenames, thus reducing the probability of overwriting files by accident.
• Resolution - Use this parameter to select a resolution or create a new one. Be sure
that you specify a resolution that is produced by your camera.
Motion Tab
This tab is used to configure options related to the robot’s motion. Parameters can be
specified for a specific behavior, otherwise the default values will be used.
