StreamLive ProConnect Wirecast to StreamLive Pro with an RTMP Server
Send Wirecast's program to StreamLive Pro through an RTMP Server output and reach YouTube, Facebook Pages and more with one upload: Address, Stream, settings and fixes.
Wirecast can stream to any server through its generic RTMP Server destination. Point that destination at StreamLive Pro, with the address and the stream key from the Encoder card, and one output from Wirecast reaches every channel you tick in StreamLive Pro. You keep Wirecast for the production and send a single stream, instead of one output per network from your own connection.
The Wirecast steps follow Telestream's own support article, Wirecast: Output Destination - YouTube (RTMP Stream Now event), and the Wirecast 14 User Guide for Windows, both checked 5 November 2026. Menu names can differ between Wirecast versions.
Before you start
- A paid StreamLive Pro plan. Receiving a stream from other software is on the paid plans; the 7-day trial streams from the browser studio. See the pricing page.
- Channels connected under Connections.
- Wirecast installed, with your shots ready. Telestream's user guide lists port 1935 for RTMP streaming, so the network must allow it.
Steps
- Open the Encoder card. In StreamLive Pro click New stream and choose Stream from software like OBS (RTMP / SRT). Open the RTMP tab and copy the address and the stream key.
- Open Wirecast's output settings. In Wirecast choose Output, then Output Settings, and add a new output destination.
- Choose RTMP Server. As the destination, choose the generic RTMP Server, not a named service.
- Fill in Address and Stream. Telestream's article puts the server URL in the RTMP Address field and the stream name or key in the RTMP Stream field. Paste the StreamLive Pro address into Address and the key into Stream.
- Pick the encoding. Choose an H.264 preset with AAC audio. If your version asks for a keyframe interval in frames, enter twice the frame rate (60 at 30 fps) for a keyframe every 2 seconds. Keep the bitrate within what your upload holds.
- Tick your channels in StreamLive Pro. Switch on the destinations in the Channels list and keep the Live stream page open and in front. It checks for your stream every ten seconds and sends it out when it arrives.
- Start streaming in Wirecast. Within about ten to thirty seconds StreamLive Pro shows that the stream was detected.
- End from StreamLive Pro. Press Stop stream to end on every network, then stop the stream in Wirecast.
What the ingest accepts
| Item | Value |
|---|---|
| Video codec | H.264 only |
| Audio codec | AAC |
| Bitrate (video and audio together) | 2 to 14 Mbps |
| Keyframe interval | 2 to 10 seconds; 2 is safest, and YouTube asks for 2 and no more than 4 |
Sources: Cloudflare Stream: Start a live stream and YouTube Help: live encoder settings. The keyframe idea is explained in What is a keyframe interval, and why set it to 2?.
Wirecast's own multistreaming or StreamLive Pro
Wirecast can add several output destinations and send each one from your computer. Each extra destination is another full upload from your line. Sending one output to StreamLive Pro keeps the upload at one stream, and adds per-network titles, YouTube and Facebook comments in one chat, and Shorts after the broadcast. Where Wirecast is the stronger tool is in Wirecast alternative for Mac and Windows: an honest look.
What we have not checked
We have not tested a specific Wirecast version against StreamLive Pro, and the Telestream pages we read do not say whether every edition accepts rtmps:// addresses, so this page uses the RTMP tab. If your Wirecast offers SRT output, the SRT tab is explained in Stream with SRT from OBS, vMix or a hardware encoder. Run a test with one unlisted YouTube channel before an important show.
What can go wrong
| Symptom | Fix |
|---|---|
| Wirecast cannot connect | Address and Stream swapped, or a space at the end. Copy both again |
| Works at the office, fails at the venue | Port 1935 is blocked there. Try the RTMPS tab if your Wirecast accepts rtmps://, or another network |
| Wirecast streams, networks empty | The Live stream page was closed or in the background, or no channel was ticked. See OBS is streaming, but YouTube and Facebook show nothing |
| Detected, no picture | An HEVC preset, or keyframes too far apart. See My encoder says it is streaming, but there is no picture |
| Stutter on every network | The bitrate is more than the line holds. Lower it |
Frequently asked questions
Can Wirecast stream to YouTube and Facebook at the same time through StreamLive Pro?
Yes. Wirecast sends one output to StreamLive Pro, and our servers send it to YouTube, your Facebook Page and every other channel you ticked.
Which Wirecast destination do I choose?
The generic RTMP Server destination. Put the StreamLive Pro address in Address and the key in Stream.
What keyframe setting should Wirecast use?
A keyframe every 2 seconds. If the setting is in frames, enter twice the frame rate, for example 60 at 30 fps.
Can I use Wirecast during the StreamLive Pro trial?
No. Streaming from other software is on the paid plans. The trial streams from the browser studio.
Does StreamLive Pro replace Wirecast?
Not for local production. Wirecast stays the switcher on your computer; StreamLive Pro takes its one output to every network.
