Parameter Description
Encode Mode Modes of H.264M, H.264H, MJPEG, and H.265 can be selected.
Resolution
The higher the value, the clearer the overall image. For each resolution,
the recommended bit stream value is different.
The resolution of sub stream cannot be greater than that of main
stream.
Frame Rate (FPS)
The higher the value, the smoother the video image. The frame rate
might vary due to different resolutions.
Bit Rate Type
You can select from
VBR
(variable bitrate) and
CBR
(constant bitrate).
●
VBR
: Gives the best balance between quality and file size as the
bitrate can be altered depending on the video.
●
CBR
keeps the bitrate the same during encoding, and it is more
advantageous to use when the network connection is limited to
performing at, for example, 320 Kbps.
