Limit to 30 fps – if your video input is 60 fps, limiting your



streaming to 30 fps will improve quality in most cases.

Latency Mode – only "Normal" is currently available.



Encoding Mode – Fixed or Variable. Variable allows the encoder to



"burst" data at a higher rate to maintain quality, but may not be

ideal for some networks. Fixed is the preferred mode.

Key Frame Interval – Determines how often a MPEG GOP I frame



and H264 "IDR" is produced. More key frames allow decoders to

start the video sooner, but reduces compression efficiency. Value

of 2 to 10 seconds is recommended depending on bit rate.

Video Encoding and Rate – Only H264 is available. The output bit



rate is set in Kbps (e.g. 1000 Kbps = 1 Mbps).

H.264 Profile – select Baseline, Main, or High profile. Generally,



lower bit rates should use Baseline, medium rates use Main, and

higher rates use High. High profile also puts more burden on the

decoding players.

Audio Encoding – Only Advanced Audio Codec Low Complexity



(AAC-LC) is available. The audio sampling rate is always 48 KHz.

The audio bit rate determines the quality of the audio. 128 Kbps is

a good choice for most uses.

Output Settings
