Why do I need multiple qualities of the same video?

To ensure an optimal viewing experience on any device and in varying network conditions, our servers transcode the uploaded, recorded or – in the case of livestreaming – broadcasted video to multiple qualities. The video player will then choose the best possible quality, taking into account available bandwidth and processing power available to the device used for watching.

This technology is often referred to as adaptive streaming, because the video quality adapts to the individual conditions¬†of the viewer. Viewers don’t need to do anything for this to work, it just happens automatically.
