Video Bitrate (bps)
The bitrate of the video specifies the amount of information stored in the video. The higher the bitrate
is, the clearer the video is. However, when choosing your encoder settings for streaming, you should
first check your available upload bandwidth. A good rule of thumb is for the bitrate of your stream to
use no more than 50% of your available upload bandwidth capacity on a DEDICATED line. For example,
if the result you get from a speed test shows that you have 2Mbps of upload speed available, your
combined audio and video bitrate should not exceed 1Mbps.
Usually high bitrate means good image quality; however, there are also exceptions. For example, SD
video may appear acceptable at 1000 Kbps (1M) but HD video is unacceptable at 1000 Kbps.
Available video bitrates are listed as follows:

10M

8M

6M

4M

2M

1M

512K

256K
Audio Bitrate (bps)
