Since viewers of live or recorded streams use different networks and come from various locations, the best method to deliver streaming video to a worldwide audience is by using multiple bitrates and resolutions. Playback quality depends on the viewer connection to the internet and type of device they use. Most social media sites and streaming services support "adaptive bitrate" technology: during playback the stream adjusts to the viewer capability to receive low to high quality video. Videolinq top tier plans support ABR on live streams. All Videolinq plans support ABR for video-on-demand.

Before configuring a live stream, confirm what's the bitrate and resolution set by your target endpoints (example: YouTube accepts 4K video up to 50 Mbps*, but Facebook Live limits the stream to 1080p at a maximum of 4 Mbps). When streaming to social media sites, we recommend sending a minimum of 720p stream at 4 MBps to Videolinq and distributing the same stream to all endpoints.
