01What is a hardware video encoder?
It is a small box that takes the picture from your camera or video switcher, usually over HDMI or SDI, compresses it and sends it to a streaming server. No computer has to stay on during the show, so a laptop update or a full disk cannot take you off air.
02How do I connect a hardware encoder to an RTMP server?
Open the encoder's web page or app, find its streaming or publish settings and choose RTMP. Type the server URL, then the stream name in its own field, then the publish username and password. For a Primcast channel all four are in your setup email, and the tutorials above show where each one goes on a Teradek, Epiphan or Hauppauge box.
03What bitrate and keyframe settings should a hardware encoder use?
Set the keyframe interval to 2 seconds and keep it fixed. For bitrate, stay under 5 Mbps for video and audio together, which is the ceiling on our paid live video plans and plenty for 1080p. On a slow upload, choose a lower figure and a lower resolution rather than letting the encoder drop frames.
04Can I stream 4K from a hardware encoder?
Not on a live video channel. They carry 1080p, so set a 4K encoder to output 1080p. If you really need 4K, or more than 1,000 people watching at once, a dedicated streaming server is the right home for it, and the same encoder simply points there.
05Will my encoder work if it has no tutorial here?
Yes, if it can send H.264 video over RTMP. Look for the words RTMP, custom server or publish in its menus and use the values from the settings list on this page. If it only speaks SRT, the Pro and Platinum plans of our video CDN take it.
06How many people can watch my encoder's stream?
Up to 1,000 at the same moment on every live video channel. Your viewers watch in their browser through a player you embed on your own page.
07Who can help me if my encoder still will not connect?
Open the chat on this page. Our AI assistant answers in seconds, can check your channel and your settings while you wait, and brings in a person from the team whenever you ask.
