Description
Setting
I-frame
interval
You can set the I-frame interval when
Coding protocol
is set to
H.264
.
I-frame is an intra-coded frame that
represents a fixed image independent of other
picture types. Each group of picture (GOP)
begins with this type of frame.
Decreasing the I-frame interval improves the
video quality but devours more bandwidth.
[Value range]
An integer ranging from 1 to
60
[Default value]
25
NOTE
If the frame rate is low, you are
advised to set the I-frame
interval to the same value as the
frame rate; otherwise, the media
stream request duration is long.
JPEG
quality
When you set
Coding Protocol
to
MJPEG
,
the image quality can be adjusted.
Increasing the JPEG quality improves the
video quality but devours more bandwidth.
[Value range]
An integer ranging from 10 to
90
[Default value]
60
