Parameter Function
Main Stream Code-Stream Type General bit stream.
Encode Mode Select from four options for Encode Mode: H.264 (Main Profile), H.264H
(High Profile), H.264B (Baseline Profile), and MJPEG mode.
H.264: Main profile encoding mode.
H.264H: High profile encoding mode.
H.264B: Baseline profile encoding mode.
MJPEG: In this encoding mode, the video needs a larger bit stream to
guarantee the video definition. You can use the maximum bit stream
value in the Recommended Bit to get better video output.
Resolution You can select from multiple resolutions from the drop-down list.
The recommended bit stream value is different for each resolution.
Main Stream Frame Rate (FPS) PAL: 1‒25 fps; NTSC: 1‒30 fps.
Bit Rate Type Select either VBR or CBR.
Note You can set the video quality in VBR mode.
Reference Bit

and frame rate that you have selected.
Bit Rate In VBR, the Bit Rate here is the maximum value. In CBR, it is a fixed
value. See the Reference Bit Stream for a recommended value.
I Frame Interval Set the number of P-frames between I-frames. The value ranges from 25
to 150. The default value is 50.
The recommended value for I Frame Interval is 2 times the frame rate
setting.
