Adaptive Bitrate Streaming
Viostream uses a technology called HTTP Live Streaming (HLS) to give your audience the best possible viewing experience. The Viostream player automatically adjusts the bitrate of your video to best suit every viewer's device and internet connection.
When a viewer's internet connection is poor, the player will serve a more compressed version of your video, ensuring that smooth playback continues and buffering is avoided. When the connection improves, the player will automatically increase the quality, giving the viewer the sharpest playback experience.
By using adaptive bitrate streaming, Viostream is able to seamlessly stream video to desktop, tablet and mobile.
Bitrate Presets
Viostream has configured you account to use default presets that are designed to deliver a quality viewing experience across all playback conditions.
| Quality | Width | Height | Video bitrate | Audio bitrate |
|---|---|---|---|---|
| 1080p | 1920px | 1080px | 5Mbps | 96 Kbps |
| 720p | 1280px | 720px | 2.5Mbps | 96 Kbps |
| 540p | 960px | 540px | 1.5Mbps | 96 Kbps |
| 432p | 768px | 432px | 0.9Mbps | 96 Kbps |
| 288p | 512px | 288px | 0.6Mbps | 96 Kbps |
If you would like to adjust the presets for your account, please contact Customer Success via the Live Chat.
Transcoding
When you upload a video to Viostream it is converted into HLS, with multiple copies (renditions) corresponding to the bitrate settings on your account. Please note that video quality is not upscaled - for example if you upload a 720p video, the maximum bitrate available will be 720p.
