MPEG4
E Bitrate For setting the MPEG4 encoding bit rate.
[Setting range: 64 kbps to 8000 kbps]
F Bitrate
Control
For selecting whether to set the MPEG4 rate control mode to CBR (Constant
Bit Rate) or VBR (Variable Bit Rate).
CBR : Encoding is performed at a fixed bit rate regardless of the
condition of the input video signals. Enables easy forecast of
the bit rate.
VBR : Changes the bit rate according to the condition of the input
video signals. Picture quality is stable, but forecast of the bit rate
is difficult.
G FPS For setting the MPEG4 frame rate.
[Setting range: 1 fps, 7.5 fps, 10 fps, 15 fps, 25 fps, 30 fps]
H I Frame
Interval
For setting the I-frame interval. MPEG4 starts encoding from the I-frame.
Shortening the interval stabilizes the picture quality even when there are
rapid changes in the video image. However, the picture quality for images
with little change will deteriorate. In addition, when multicast packet loss
occurs, the time interval required to restore the image is shorter.
[Setting value:30, 60, 90, 120, 150]
I Priority For selecting whether to assign priority to the frame rate or picture quality
during MPEG4 encoding.
FPS : Assigns priority to frame rate. Select this setting to enable
smooth monitoring of motion images.
Quality : Prioritizes image quality.
