![]() Most production equipment will work at either 44100 hz or 48000 hz.Sample rates above this are unsupported and can cause a failure in the stream or recording. ![]() ![]() 48000 hz is the highest supported sample rate.In addition, the perceived quality gain at bitrates above 320kbps is minimal, so it is recommended to keep the audio bitrates within the ranges suggested above. The audio bits take up much less of the overall bandwidth than your video bitrate.If your available bandwidth is limited, you should reduce both your resolution and your bitrate accordingly.Using too high or low of a bitrate can lead to poor image quality or buffering for your viewers. It is important that you use the guidelines provided in the chart above to appropriately match your bitrate to the resolution you are using. Higher resolutions require a higher bitrate to achieve the same perceived quality video stream.For example, "talking heads" sitting at a desk with a relatively static shot can use the lower end of the bitrate recommendations provided above, whereas a sporting event or concert with high motion and many moving cameras will typically require a significantly higher bitrate at the same resolution to have the same perceived quality. Higher motion content requires a higher bitrate to achieve the same perceived quality video stream. ![]() This is one of the reasons why having adequate headroom in your bandwidth is so important. Depending on the level of motion in your video content and your keyframe interval, the actual encoded bitrate of the stream will go higher and lower than the target. With a variable bitrate encoder, when you set a bitrate, you are only setting a target.
