Set up OBS, vMix or a hardware encoder

Copy your push details from the Studio into OBS, vMix or a hardware encoder, choose settings that hold up, and confirm the picture arrives.

Whoever runs the encoder at the venue needs two things from the Studio: where to push, and the key that proves it’s you. This page shows where to find both and where they go in each encoder. If your camera operators have their own sign-ins, they get feed details without anyone copying keys around — see crew and operator logins.

Hardware encoders

Most hardware encoders offer RTMP, SRT or both. For RTMP, paste the RTMP URL and stream key into their matching fields; if the encoder has a single address field, enter the RTMP URL, a slash, then the key. For SRT, set the encoder’s mode to match the Mode the Studio shows, and enter the hostname, port and stream ID from the feed page — or paste the SRT URL if the encoder accepts a full address.

Encoder settings that hold up

The right numbers depend on your venue’s connection and your encoder, so start from these choices rather than a fixed recipe.

SettingChooseWhy
Video codecH.264Plays on your site and apps and is accepted by every simulcast destination
AudioAAC, stereoAccepted everywhere; other audio formats can be refused by destinations
Rate controlConstant bitrate (CBR)A steady stream is easier on destinations and on adaptive quality for viewers
BitrateComfortably below the upload speed you measured at the venue — and for an SRT feed, no higher than the Max Bitrate on its feed pageLeaves headroom for the moments the connection dips
Keyframe intervalA fixed value, never automaticViewers join quickly and quality levels switch cleanly
Resolution and frame rateWhat the encoder can hold steadily at that bitrateDropped frames look worse than a lower resolution

Check the picture arrived

  1. 1
    Find the stream

    Open Studio → Feed Console → Feed Hub for a feed, or Event Hub for an event. Both refresh every 5 seconds while Auto refresh is on, and the card switches to live with a moving preview.

  2. 2
    Confirm your settings

    Open the stream’s detail page and compare Resolution and Bitrate (Mbps) with what you set in the encoder.
