 Maximum Quantizer—A parameter related to video quality.

The value range is from 2 to 31.

 Input Filter Mode—The level of filtering applied to the video

signal before it is encoded, helping to remove high

frequency noise from lower quality cameras or noisy video

feeds.

 Resolution—The number of pixels (columns * lines) for each

picture of the video sequence.

 Rate Control Mode—The mode controlling the bit rate

variation. The available modes are:

 CBR—The Constant Bit Rate mode is the most effective

to maintain the target bit rate. Video quality may suffer

and the frame rate may decrease. This mode should be

used when transmitting video over networks that have

very limited bandwidths, and with an intra interval

value of 0.

 CFR (Constant Frame Rate)—This mode maintains the

target frame rate. Video quality may suffer and the bit

rate may exceed the target value.

 Nextiva Storage—This is the optimized mode to be

used only for the Nextiva enterprise video management

software.

 Intra Interval—The frequency at which a complete video

frame (called I-frame) is sent by the encoder. Possible

values are in the 0–1000 range. A value of 0 indicates that

no I-frame will be sent automatically by the device; a value

of X means that a complete image refresh will occur every

X frames.
