H.264 & MPEG-4
GOV Settings
The GOV structure describes the composition of the video stream. Setting the GOV-length to a higher value saves considerably
on bandwidth but may have an adverse effect on image quality.
Bit Rate Control
The bit rate can be set as Variable Bit Rate (VBR) or Constant Bit Rate (CBR).
VBR adjusts the bit rate according to the image complexity, using more
bandwidth for increased activity in the image, and less
for lower activity.
CBR allows you to set a fixed Target bit rate th
at consumes a predictable amount of bandwidth. As the bit rate would usually
need to increase for increased image activity, but in this case cannot, the frame rate and image quality are affected
negatively. To partly compensate for this, it is possible to prioritize either the frame rate or the image quality whenever the bit
rate needs to be increased. Not setting a priority means the frame rate and image quality are equally affected.
Notes:
•
AXIS M1054 does not support MPEG-4.
• To determine a reasonable bit rate, go to Setup > Video & Audio > Video Stream > Image, check the Include
checkbox and enter the code #b in the Include text: field. The current bit rate will display as a text overlay on the Live
View page.
• To view the image stream while configuring the GOV settings and Bit rate control, select Open... under Preview.
