3
FPS
Frame rate. Normally, more “frame rates”, the video will be more smooth.
And there’s a trick to setup the frame rate. For example, if your input is 1080p_60hz in, the frame
rate better to 60fps or 30fps (same frame rate as the input or a half as the input). This is helpful
with the video quality.
Another, if your input does not have so many “frame rates” and you set to a value which is much
more than the “real” frame rate, your configuration will not be working and keep the same frame
rates as the input.
Key interval: 5~200
It means how many P frames encode one I frames, for instance, now frame rate is 30fps. if “key
interval” is set to 60, that means encode is “every 2 seconds per I frame”.
Bitrate
the number of bits per second output from video data, the Unit is Kbps.
Bitrate setting Reference
1080p@60fps
Resolution: 1920x1080, bitrate: 4500Kbps~9000Kbps
1080p@30fps or lower
Resolution: 1920x1080, bitrate: 3000Kbps~6000Kbps
720p@60fps
Resolution:1280x720, bitrate:2200Kbps~6000Kbps
Bitrate Control
CBR, VBR.
CBR:
means that a stable encoding bit rate is guaranteed within the bit rate statistical time.
VBR:
means that a stable picture quality is ensured within the bit rate statistical time when the
bit rate changes.
