Datavideo KMU-200 Instruction Manual page 29

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
 2M
 1M
 512K
 256K
