Recommended streaming options
– Check your outbound bandwidth at speedtest.net. Based on your available outbound bandwidth, choose the one highest quality from below that you can reliably stream. A good rule of thumb is to encode only up to 50-60% of your outbound bandwidth. For example, if you have 2Mbps of upload speed available, your combined audio and video bitrate should not exceed 1Mbps. The FPS value of your stream should match your original video source.
– We recommend streaming at a resolution with a 16:9 aspect ratio. It is best to either match your original video source, or scale it down. For example, capture at 720 and stream at 720. Or capture at 720 and stream at 480. You should never be scaling up and streaming at a higher resolution than your original video source. For example, it does not make sense to capture at 720 and stream at 1080. You will have no gain in quality and you are using more bandwidth than is necessary for you and your viewers.
– Ensure your encoding CPU can handle your encoding settings. HD streams and high bitrate streams take significantly more CPU resources to capture and encode. If you find your stream is dropping frames, you most likely are over-taxing your encoder. Reducing the input resolution size and or reducing your stream output resolution and bitrate can fix this issue. Most professional encoding programs allow you to monitor the CPU usage and whether or not you are dropping frames while encoding.
