Frequently Asked Questions

No — the Streaming Encoder 4K is completely self-contained. Simply connect your 12G-SDI camera or source, connect to ethernet or tether a 4G/5G phone, and start streaming. There is no PC, no streaming software and no complicated configuration. Everything is controlled via the front panel buttons and LCD, or remotely via the Blackmagic Streaming Utility software over ethernet.
The Streaming Encoder 4K supports any RTMP or SRT destination, which covers virtually all major platforms. Pre-configured profiles are available for YouTube, Facebook, X (Twitter), Twitch, Restream.IO, Vimeo, BoxCast, Castr and many more. It also works directly with Zoom, Skype, Microsoft Teams and OBS Studio via its USB webcam output.
H.264 (AVC) is the most widely compatible streaming codec, supported by all platforms via RTMP. H.265 (HEVC) delivers better quality at lower bitrates, particularly important for 4K streaming where bandwidth is critical. The Streaming Encoder 4K supports H.264 via RTMP and both H.264 and H.265 via SRT. For 4K streaming, H.265 via SRT gives the best quality-to-bandwidth ratio.
You connect a 4G or 5G smartphone to either of the USB-C ports on the front or rear panel using standard phone tethering. The Encoder automatically uses the phone's mobile data connection for streaming. If ethernet is also connected, you can configure priority — ethernet primary with phone as automatic failover, or phone primary. This makes it ideal for field production where fixed internet is unavailable or unreliable.
The Streaming Decoder 4K receives H.264 or H.265 streams — from the Streaming Encoder 4K, Blackmagic cameras, or any compatible source — and converts them to 12G-SDI and HDMI video outputs. It is primarily used to create point-to-point broadcast links: Encoder at the camera/remote location, Decoder at the studio or production centre. The Decoder also sends tally, talkback and camera control back to the encoder end, enabling full remote camera operations.
The Streaming Encoder 4K can stream to multiple destinations simultaneously when used with a streaming service like Restream.IO, which distributes to multiple platforms from a single RTMP/SRT input. For direct multi-destination streaming without a third-party service, you would need to route to multiple encoders or use a streaming platform with multi-destination features.
