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 RATE | 25 or 30 |
KEYFRAME INTERVAL | 2 secs (or 2x frame rate) |
SCANNING | Progressive |
ENCODING BITRATE | Constant (CBR) |
AUDIO CODEC | AAC |
AUDIO BITRATE | 128 kbps |
AUDIO CHANNELS | 2 (Stereo) |
AUDIO SAMPLE RATE | 48 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:
ULD | LD | SD | HD | FHD | |
Name | Ultra-Low Definition | Low Definition | Standard Definition | High Definition | Full High Definition |
Video Bitrate (kbps) | 350 | 350 – 800 | 800 – 1200 | 1200 – 1900 | 1900 – 4500 |
Resolution Width (px) | 426 | 640 | 854 | 1280 | 1920 |
Resolution Height (px) | 240 | 360 | 480 | 720 | 1080 |
H.264 Profile | Main | Main | High | High | High |
Audio Bitrate (kbps) | 64 | 64 | 128 | 256 | 256 |
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.
