Expert Settings
Click this button to reveal the additional fields for Encoder Profiles. You can use the expert
settings to adapt the I-frame quality and the P-frame quality to specific requirements, if
necessary. The setting is based on the H.264 quantization parameter (QP).
GOP structure
Select the structure you require for the Group of Pictures here. Depending on whether you
place greater priority on having the lowest possible delay (IP frames only) or using as little
bandwidth possible, you can choose between IP, IBP, and IBBP.
Averaging period
This parameter allows you to set the averaging period ....
Options are: No averaging (default), 1 min, 2 min, 5 min, 10 min, 30 min, 1h, 2h, 5h, 12h, 1
days, 2 days, 3 days, 7 days.
I-frame distance
This parameter allows you to set the intervals in which the I-frames will be coded. With the
Auto setting, the encoder inserts I-frames as necessary. An entry of 3 indicates that only every
third image is an I-frame; the frames in between are coded as P-frames. Note that if you have
selected IBP as GOP structure only even values are supported. If you have selected IBBP as
GOP structure only 3 or multiples of 3 are supported as value.
Min. P-frame QP
This setting adjusts the maximum image quality of the P-frames. Auto automatically adjusts to
the optimum combination of movement and image definition (focus).
The value 9 represents maximum image quality, a value of 51 represents minimum quality.
With the slide control, define a control range from a chosen value to 51. The encoder delivers
the best possible quality within this control range while maintaining the maximum bit rate.
I/P-frame delta QP
This setting sets the image quality of the I-frames. Select Auto to ensure that the maximum bit
rate is not exceeded. Auto automatically follows the P-frame image quality.
Default
Click Default to return the profile to the factory default values.
