    The following are recommended encoder settings for live streaming. As you set up your encoder, please be aware of the default settings of your encoder. For instance, the default settings in Wirecast are for 720p HD videos.

    Recommended Encoder Settings

    The following settings are required for live streaming with Dacast, regardless of your selected resolution and bitrate:

    VIDEO CODEC
    H.264 (x264 may work)
    FRAME RATE25 or 30
    KEYFRAME INTERVAL
    2 secs (or 2x frame rate)
    SCANNINGProgressive
    ENCODING BITRATEConstant (CBR)
    AUDIO CODECAAC
    AUDIO BITRATE128 kbps
    AUDIO CHANNELS2 (Stereo)
    AUDIO SAMPLE RATE48 kHz (48,000 Hz)

    Resolution & Bitrate Settings

    Please select one of the following configurations and ensure your encoder is set up with these exact settings to help prevent streaming issues:

    H.264 ProfileMainMainHighHighHigh
    Audio Bitrate (kbps)6464128256256

    Single Bitrate

    We recommend a standard or low definition (480p/360p) under 1000kpbs (audio and video bit-rates included based on the table above).

    Multi Bitrate

    Please keep in mind that:

    • Your total bandwidth requirements will be the total of all your streams added together, audio and video bitrates.
    • Your internet speed connection has to be at least the double of your total bandwidth requirements (to test your internet speed connection: http://testmy.net/)

    Note: To record your stream using Dacast Auto Archiving Beta feature, please remember that the maximum bit-rate allowed is 3.5 Mbps. It means that if you are doing a multi bit-rate stream, your total amount of bandwidth should not exceed 3.5Mbps.
