Understanding the limits of streaming video

This guide details the elements necessary for the optimal diffusion of your flows on the service ofStreaming videoInfomaniak.

Recommended Bitrate based on video quality

When encoding your flows, it is essential to adapt the bitrate to the desired quality:

• SD video (480p): minimum 1,000 kbit/s.
• HD video (720p): between 2,500 and 4,000 kbit/s.
• Full HD video (1080p): between 5,000 and 8,000 kbit/s.
• 4K Ultra HD video (2160p): from 15,000 kbit/s.

Ensure adequate Internet throughput

To ensure uninterrupted streaming, it is recommended that you have an Internet throughput at least twice the bitrate of your encoded stream, e.g.:

• For a full HD stream encoded at 6,000 kbit/s, a minimum Internet rate of 12 Mbit/s is required.
• This margin avoids interruptions due to variations in connection or other devices using the same network.

Use multi-bitrate for maximum adaptability

Themulti-bitrateallows your stream to be available in several qualities, adapted to the connections of the spectators. This ensures:

• A fluid experience for those with limited bandwidth.
• Optimal quality for spectators with a quick connection.

Optimize your flows for mobile users

Mobile spectators may encounter fluctuating network conditions. To improve their experience:

• Encoding at a maximum bitrate of 1,000 kbit/s per stream for lower resolutions.
• Implement the multi-bitrate to automatically adjust the quality.

Good practices for successful encoding and dissemination

• Test your Internet connection before each broadcast.
• Prioritise a reliable encoder and update its parameters according to the above recommendations.
• Make sure your network is dedicated to broadcasting to avoid disruptions caused by other uses.
• Provide a backup solution (such as a 4G/5G modem) in case of connection problems.
