Before setting your encoder, make sure you have sufficient bandwidth. See the table below for the
required bandwidth for H.264 video streaming at various resolutions.
Resolution
H.264/AVC Bandwidth Required
480p
1.5 Mbps
720p
3 Mbps
1080p
6 Mbps
Resolution
Once you’ve chosen your encoder, 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:
1920x1080
1280x720
720x576
720x480
640x480
320x240
Frame Rate
Select a frame rate from the drop-down menu for video streaming. Note that frame rate should always
match the frame rate of the video source.
60.00
59.94
50.00
30.00
29.97
25.00
24.00
23.98
20.00
15.00
Profile
Profile sets the H.264 encoding profile for your stream. The available options are Baseline, Main,
and High. Typically, High profile provides the best image quality and is suitable in most instances.
