Live streaming – Recommended settings

Live streaming settings – updated for Streamio live transcoding (beta).

Live streaming without live transcoding

Once you are logged in, you will find the settings for sending the stream to Streamio with your streaming hardware or software under the Live tab and the “Streaming settings” heading. These settings are customised for your account. The settings of different streaming solutions are similar, if your system does not exist, it is very likely that it works with one of the other systems’ settings.

Recommended default settings:

Codec: H.264
H.264 Profile: High
  • Lower to main or baseline if you have receivers with older equipment
Bitrate: 2500 kbps
  • Raise for higher image quality if the receivers can handle it (risk of stuttering and buffering otherwise)
  • Lower for lower cost of streaming (and more people able to receive without buffering).
FPS: 30
  • Increase to 60 for smoother motion in the movie, requires higher bitrate to maintain quality
Audio Bitrate: 128kbps
  • Turn up if the sound is essential – for example, for music
Audio codec: AAC
Resolution: 720p
  • Upgrade to 1080p or more if image quality is very important – requires more bitrate, costs more and places higher demands on the receiver
  • Drop to 540p or 480p to save bandwidth, money and safer receiver performance – but lower quality.

Recommended settings with Streamio live transcoding (beta)

With Streamio Live transcoding, you send in a high-resolution video that is automatically adjusted to lower qualities. Each visitor then gets the stream that the player thinks works best (which can change during the broadcast if, for example, the viewer gets worse coverage.)
Live transcoding is only relevant if you want to have a high quality video, without shutting out viewers. Therefore 1080p video is required as input. Rackfish offers fully customized solutions for live video transcoding for those with other requirements.

Recommended settings for Streamio live transcoding:

Codec: H.264
H.264 Profile: High
Bitrate: 6000 kbps
  • Higher and lower works, we don’t recommend going higher than 8000 kbps. Please contact us if you need more advanced transcoding.
FPS: 25, 30, 50 or 60
  • 25 and 30 fps will be kept intact for all transcoded resolutions (480p, 720p, 1080p).
  • 50 and 60 fps will be halved for the lower transcoded resolutions (480p, 720p)
Audio Bitrate: 256kbps
Audio codec: AAC
Resolution: 1080p
  • Streamio Live Transcoder will create and deliver 1080p, 720p and 480p
  • With other resolution, the stream will not transcode.
