Dynamic Delivery and High Quality

Brightcove's multi-bitrate streaming feature improves a viewer's experience by enabling you to deliver videos with the resolution and bit rate that best matches the viewer's connection speed. The videos in your Media Library can include one or more renditions encoded at different bit rates and sizes. The Brightcove player automatically selects the highest quality rendition that the viewer's download connection speed can support, taking into account the rendition's resolution and bit rate.
