By default, videos use a technology called adaptive streaming by which the player will intelligently choose the highest quality possible based on your network connection, graphics processing ability, and player size.
As long as the original source file and their viewing environment support it, videos can be viewed in resolutions up to 1080p at 5Mbps.
For audio, we encode to two stereo channels, regardless of the channels on the original video file. 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. If your playback is choppy or slow, try adjusting the quality/resolution in the web player manually by clicking the gearwheel icon in the lower right corner of the player.
