FAQ
Common questions about hardware video encoder setup, network configuration, server connection and troubleshooting your video broadcast device.
What is a hardware video encoder and when should I use one?
A hardware video encoder is a dedicated physical device that captures a video signal and encodes it for live streaming, independently of a computer. Devices like the TeraDek CUBE and Epiphan encoder are designed for professional broadcast environments where reliability, low latency, and portability are critical. They are ideal for live events, sports broadcasting, remote productions, and any situation where a stable 24/7 video stream is required without depending on a PC.
How do I connect a hardware video encoder to a streaming server?
You will need your Server Room server hostname, port number, stream key or mount point, and stream password. Access your encoder's configuration interface - usually a built-in web panel reached by entering the device's IP address in a browser - and enter your server credentials in the streaming output settings. Our individual tutorials for TeraDek CUBE, Epiphan, and SelenioFlex walk through every field with screenshots.
What video formats and resolutions do hardware video encoders support?
Most professional hardware video encoders support H.264 (AVC) and H.265 (HEVC) encoding at resolutions from 480p up to 1080p or 4K, depending on the model. The TeraDek CUBE and Epiphan encoders support H.264 output compatible with RTMP, RTSP, and HLS streaming protocols. Always check that your encoder's output format matches what your Server Room streaming plan supports before configuring your device.
What network settings does a hardware video encoder require?
Hardware video encoders need a static or DHCP-assigned IP address on your local network, outbound access on the streaming port used by your server (typically port 1935 for RTMP), and a stable high-bandwidth internet connection. Video streams require significantly more bandwidth than audio - allow at least 4 Mbps upload for a 720p stream and 8 Mbps or more for 1080p. If your encoder is behind a firewall or NAT router, ensure outbound TCP traffic on the streaming port is not blocked.
What is the difference between OBS and a dedicated hardware video encoder?
OBS (Open Broadcaster Software) is a free software encoder that runs on a computer and offers extensive scene mixing, overlays, and customisation. Dedicated hardware encoders like TeraDek CUBE or Epiphan are standalone devices with no software dependency, offering greater portability, reliability, and consistent performance at the cost of flexibility. OBS is ideal for desktop streaming and content creators, while hardware encoders suit field production, live events, and unattended 24/7 broadcasts.
