Resolution
The first step of encoder setup is to adjust the image size. It is best to either match your original video
source or scale it down. For example, capture at HD 720 and stream at HD 720. Or capture at HD 720
and stream at 540 (high).
You should never be scaling up and streaming at a higher resolution than your original video source.
For example, it does not make sense to capture at 720 and stream at 1080. Note that you will also
have no gain in quality and you are using more bandwidth than is necessary for your viewers.
You should also be aware that higher resolutions require greater processing power to encode the
stream. Attempting too high of a resolution on too little processing power can result in degraded
image quality and corrupted or interrupted streams or recordings.
Resolutions available for your stream encoder are listed as follows:
 1080x1920
 720x1280
 576x720
 480x720
 480x640
Frame Rate
Select a frame rate from the drop-down menu for video streaming. Note that frame rates should
always match the frame rate of the video source.
 60.00
 50.00
 30.00
 25.00
 20.00
 15.00
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
