Allow enhanced prediction
This function allows for multiple references in H.264 and H.265 streams, which can reduce
bitrate. Some decoders do not support this feature and therefore can be disabled.
Min. P-frame QP
In the H.264-protocol, the Quantization Parameter (QP) specifies the degree of compression
and thus the image quality for every frame. The lower the QP value, the higher the encoding
quality. A higher quality produces a higher data load. Typical QP values are between 18 and
30. Define the lower limit for the quantization of the P-frames here, and thus the maximum
achievable quality of the P-frames.
I/P-frame delta QP
This parameter sets the ratio of the I-frame QP to the P-frame QP. For example, you can set a
lower value for I-frames by moving the slide control to a negative value. Thus, the quality of the
I-frames relative to the P-frames is improved. The total data load will increase, but only by the
portion of I-frames.
To obtain the highest quality at the lowest bandwidth, even in the case of increased
movement in the picture, configure the quality settings as follows:
1.
2.
3.
Background delta QP
Select the appropriate encoding quality level for a background region defined in Encoder
Regions. The lower the QP value, the higher the encoding quality.
Object delta QP
Select the appropriate encoding quality level for an object region defined in Encoder Regions.
The lower the QP value, the higher the encoding quality.
Default
Click Default to return the profile to the factory default values.
Click Set to apply the changes.

Encoder Streams

When this menu is accessed while the device is recording, the following message appears at
the top of the page: "Recording is currently active. At 'Active profile' the stream profile used
for recording is displayed, and overrules the 'Non-recording profile'."
Property
Select one of the resolutions from the drop-down menu for each stream.
Non-recording profile
Select one of the following profiles for each stream:
Profile number
Profile 1

Observe the coverage area during normal movement in the preview images.
Set the value for Min. P-frame QP to the highest value at which the image quality still
meets your needs.
Set the value for I/P-frame delta QP to the lowest possible value. This is how to save
bandwidth and memory in normal scenes. The image quality is retained even in the case
of increased movement since the bandwidth is then filled up to the value that is entered
under Maximum bit rate.
Description
For a high resolution image, the video bit rate and frame quality are
adjusted to ensure that the picture quality is the priority.
