Set up rate, resolution, quality, encode and max bit stream according to the actual situation.
Then apply the settings.
Resolution
: The higher the resolution is, the clearer the image is.
FPS
: The higher the frame rate is, the more fluency the video is. However, more storage
room will be taken up.
Encode
: Including CBR and VBR. CBR means that no matter how changeable the video
resources are, the compression bitrate keeps constant. This will not only facilitate the
image quality better in a constant bitrate but also help to calculate the capacity of the
recording. VBR means that the compression bitrate can be adjustable according to the
change of the video resources. This will help you save much storage room.
Image Quality
: When VBR is selected, you need to choose image quality. The higher the
image quality you choose, the more bitrate will be required.
Average Bitrate
: When VBR is selected, you need to choose image quality.
