• MJPEG
Motion JPEG (M-JPEG or MJPEG) is a video compression format in which intraframe coding technology is
used. Images in a MJPEG format are compressed as individual JPEG images.
•
Profile
This function means that under the same bitrate, the more complex the profile, the higher the quality
of the image, and the requirement for network bandwidth is also higher.
4.1.8 Smoothing
The stream smoothness. The higher the smoothing value, the better the stream fluency, though the video
quality may not be satisfactory. The lower the value of the smoothing, the higher the stream quality,
though it may appear less fluent.
4.2 ROI
ROI (Region of Interest) encoding helps to discriminate between the ROI and background information in
video compression. The technology assigns more encoding resource to the region of interest, thus
increasing the quality of the ROI, whereas the background information is less focused.
4.2.1 Set ROI
ROI (Region of Interest) encoding assigns more encoding resource to the region of interest, thus
increasing the ROI quality, whereas the background information is less focused.
Before You Start
Check the video coding type. ROI is supported when the video coding type is H.264 or H.265.
