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 the stream encoder are listed as follows:

1080x1920

720x1280

576x720

480x720

480x640

240x320
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
