Multistreaming to 20 Platforms, Landscape and Vertical at Once

Multistreaming is broadcasting one live stream to several platforms at the same time, such as YouTube, Twitch, and TikTok. Instead of choosing where your audience watches, you reach all of them at once. In ShowUs you produce the show once, and the cloud sends it to every destination you have enabled.

Doing it yourself usually means uploading a separate stream per platform from your own computer, which multiplies the bandwidth you need, or paying for a relay service on top of your streaming software. ShowUs does the relay as part of the studio, so the show you produce and the show your audiences receive are the same product.

To stream to Twitch and YouTube at the same time, connect both accounts in the ShowUs Multi Stream section, make sure both destinations are enabled, and go live. ShowUs sends the same show to both platforms at once, and chat from both arrives in the studio. Neither connection needs a stream key copied by hand.

1. 1Open your show in the ShowUs Produce page.
2. 2In the Multi Stream section, click Connect YouTube and approve access. The YouTube guide covers it step by step.
3. 3Click Connect Twitch and approve access. See the Twitch guide.
4. 4Check that both destinations appear in the list. If either shows as Disabled, click Enable.
5. 5Start the show. Both platforms go live together, and their chats flow into the studio.

Most multistreaming sends one landscape feed everywhere, so TikTok and Instagram viewers get a wide shot letterboxed into a phone. ShowUs composites a dedicated 9:16 output beside the 16:9 one. Each scene has a landscape and a portrait layout, built from the same sources, and the producer switches both with one TAKE.

You decide which output each destination receives. A common setup sends landscape to YouTube, Twitch, and Kick, and vertical to TikTok and Instagram, all from the same show. The vertical layout is not a crop of the landscape one: you can stack guests, enlarge the speaker, and move graphics so the phone version reads well on its own.

Send each platform the format its viewers actually watch in. The split below is where most shows start. You can change it per show from the Multi Stream section.

Yes, you can go live on TikTok and YouTube at once from a computer. Add your TikTok server URL and stream key in the ShowUs Multi Stream section, connect YouTube with one click, and start the show. TikTok receives the vertical version and YouTube the landscape one. TikTok stream key access depends on account eligibility and region.

The TikTok live streaming guide shows where to find the server URL and key in TikTok LIVE Center and what to do if the key changes between streams.

ShowUs streams to YouTube, Twitch, TikTok, Instagram, Kick, X, and any destination that accepts RTMP or RTMPS. How many you can use at once depends on your plan: 3 destinations on Starter, 20 on Pro, and unlimited on Enterprise.

All six guides live in the streaming setup guides. Anything else, such as Facebook, LinkedIn, or your own media server, connects as a custom RTMP destination with its server URL and stream key.

Multistreaming splits your audience across apps, which can mean watching three chat windows while you host. ShowUs brings chat from your ShowUs event page, Twitch, and YouTube into one conversation inside the studio, so you can read and answer everyone from the same place.

The same audience desk holds polls, highlights, and your store, and it is where you spot viewers worth inviting on air. That matters most for call-in shows, where the best callers can come from any platform.

Every show records in the cloud in landscape and portrait. After the stream, both versions are ready to download as MP4, and fans can watch the replay on your ShowUs event page with the chat alongside it.

• Post the landscape recording as a full episode or podcast video.
• Cut the portrait recording into Shorts, Reels, and TikToks without reframing.
• Keep the event page working after the show, so ticket holders can watch the replay.

Most multistream problems come from a destination that changed since the last show. Run through this before you go live:

1. 1Open the Multi Stream section and confirm every destination you want is listed and enabled.
2. 2For stream-key platforms like TikTok, Instagram, Kick, and X, check whether the key changed since your last show. Some platforms issue a new key per stream.
3. 3Check that each destination is set to the right output: landscape for YouTube and Twitch, vertical for TikTok and Instagram.
4. 4Preview the vertical layout of every scene you plan to use, not just the opening one.
5. 5Pause any destination you do not want this time, rather than deleting it.
6. 6Post your ShowUs event link on each platform, so viewers everywhere know where to call in or buy a ticket.

Multistreaming and simulcasting mean almost the same thing: broadcasting one live program to several destinations at once. Simulcasting is the older broadcast term, from TV and radio stations airing the same show on two channels. Multistreaming is the term streaming tools use for sending one stream to several platforms.

The useful distinction is between sending the same feed everywhere and sending each platform the version it was built for. ShowUs does the second: one production, simulcast in two formats, so landscape and vertical platforms each get a native show.
