7.3.2 Video Coding
See Figure 16 for the ‘Video Coding’ interface
Figure 16
[Coding Level]:
Only Baseline and Main profiles are available for the
H.264 compression format. Baseline is suitable for
low video streaming delay, and the situation have
requirement on real time. Main profile is suitable for
better video quality.
[Coding]:
H.264 and MJPEG options are available.
[Resolution]:
To set the resolution of the video images.
Preferred Stream:
2592*1520/2048*1520/1920*1080;
Alternate Stream:
720*576/640*480/640*352/320*240;
[Quality]:
You can choose the video quality according to your
needs: Fine, Normal, and Basic are parameters that
can also be user-defined by choosing [advanced].
[Rate control]:
CBR and VBR are optional. CBR adopts a constant
encoding bitrate, VBR adopts variable encoding bitrate.
[Quality]:
Under the CBR setting: set the bitrate range via “Image
Quality”, where you can choose self-adaption. This
means that the bitrate can be controlled by the software
and you can also select between ±10% ~ ±50%. ±10%
means that the bitrate range is from -10% to +10% of
the value of bitrate. Under VBR setting: set the image
quality via “Image Quality”, there are 6 levels available,
going from best to worst.
