This guide details the elements necessary for optimal broadcasting of your streams on the Video Streaming Infomaniak service.

Recommended bitrate based on video quality

When encoding your streams, it is essential to adjust the bitrate to the desired quality:

• SD video (480p): minimum 1000 kbit/s.
• HD video (720p): between 2500 and 4000 kbit/s.
• Full HD (1080p) video: between 5000 and 8000 kbit/s.
• 4K Ultra HD (2160p) video: from 15000 kbit/s.

Ensure sufficient internet bandwidth

To guarantee uninterrupted streaming, it is recommended to have an internet bandwidth at least twice as high as the bitrate of your encoded stream, for example:

• For a Full HD stream encoded at 6000 kbit/s, a minimum internet speed of 12 Mbit/s is required.
• This buffer prevents interruptions due to connection fluctuations or other devices using the same network.

Use multi-bitrate for maximum adaptability

The multi-bitrateallows your stream to be available in multiple qualities, adapted to the viewers' connections. This ensures:

• a smooth experience for those with limited bandwidth.
• Optimal quality for viewers with a fast connection.

Optimize your streams for mobile users

Viewers on mobile devices may experience fluctuating network conditions. To improve their experience:

• Encode at a maximum bitrate of 1000 kbit/s per stream for lower resolutions.
• Implement multi-bitrate to automatically adjust the quality.

Best practices for successful encoding and streaming.

• Test your internet connection before each broadcast.
• Use a reliable encoder and update its settings according to the recommendations above.
• Ensure your network is dedicated to streaming to avoid disruptions caused by other uses.
• Plan for a backup solution (such as a 4G/5G modem) in case of connection problems.
