![]() ![]() We will always encode audio up to 256 Kbps, but if the internet connection does not need to use all the available bitrate, the player will provide as much as needed, given your setup. For instance, we cap 1080p video at 5 Mbps, which is significantly higher than other online video services.įor audio, we encode to two stereo channels, regardless of the channels on the original video file. Each playback resolution has its own cap in order to preserve smooth playback over the internet, and these caps correspond with our bandwidth requirements for each viewing quality. That said, we always encode at an above-average quality level, as we value quality video over anything else. (Please note that this is not supported for live video the highest resolution that live can display is 1080p.) We support 4K/HDR videos on desktop and mobile browsers. We generate multiple playback versions, and the player will intelligently choose the highest quality possible based on your network connection, graphics processing ability, and player size. Our player then delivers these segments sequentially in real-time. This process breaks a video up into smaller chunks. For implementers.By default, all videos on our site playback using a technology called adaptive streaming.
