StreamLive Pro

Stream to TikTok and YouTube at the same time

Stream to TikTok and YouTube at the same time from one computer: who gets a TikTok stream key, YouTube's live requirements, vertical or landscape, and fixes.

You can send one live broadcast to YouTube and to TikTok LIVE at the same time. YouTube connects once with a sign-in, and after that StreamLive Pro starts the YouTube live for you. TikTok works only with a stream key that TikTok gives your account, and the key changes between sessions, so you paste a fresh one before each live. Your computer uploads one stream; our servers send it to both.

Before you start

• TikTok must have given your account a stream key. TikTok decides who can stream from software. Its LIVE Safety Guide says you must be at least 18 to go LIVE and that the account needs "a certain number of followers, which may vary by market" (TikTok LIVE Safety Guide, checked 5 November 2026). If your TikTok has no stream key option, no outside tool can add it.
• YouTube live must be enabled on the channel. YouTube asks for a verified channel, no live streaming restrictions in the past 90 days, and an age of at least 16 (YouTube Help: Get started with live streaming, checked 5 November 2026). The first time, enabling can take up to 24 hours, so do it a day ahead.
• Two destinations at once. Every plan and the 7-day trial allow at least two destinations; the numbers per plan are on the pricing page.
• A source. The Browser Studio works on every plan and in the trial. OBS, vMix and other encoders need a paid plan.

Steps

1. Connect YouTube. Open Connections, add YouTube and sign in with the Google account that owns or manages the channel. With a Brand Channel, choose the channel after connecting.
2. Get the TikTok key. In TikTok, start a LIVE with a stream key and copy the Server URL and the Stream key.
3. Paste them into StreamLive Pro. Use the TikTok LIVE block on Connections, or the key window from the channel list. TikTok keys are accepted only for TikTok addresses, so a key pasted into the wrong place is refused.
4. Open your source. Click New stream at the top of the dashboard and pick Browser Studio, or Stream from software like OBS (RTMP / SRT) on a paid plan.
5. Tick both channels. In the Channels list, switch on YouTube and TikTok LIVE. If TikTok shows "New key needed", the key is from an earlier session: paste the new one.
6. Go live. Start from the studio or start your encoder. YouTube goes live by itself.
7. Confirm in TikTok if it asks. If TikTok shows a Go LIVE button for the session, press it there.

Vertical or landscape

TikTok is watched on phones held upright. On YouTube many people watch in landscape, on a computer or a TV. Both destinations get the same picture: StreamLive Pro does not make a separate vertical version for TikTok. Two honest options:

The browser studio has 9:16 safe-frame guides that show the part of a landscape picture that stays visible in a vertical crop.

After the live

When the broadcast ends, Shorts are cut from it automatically (unless you switched that off). You can post them to YouTube now or on a schedule. TikTok accepts posts only when you publish them yourself from the Publish screen: TikTok posts cannot be scheduled or sent automatically.

Frequently asked questions

Can I stream to TikTok and YouTube at the same time from a computer?

Yes, if TikTok has given your account a stream key. Connect YouTube once, paste a fresh TikTok key for each session, tick both channels and go live. Your computer uploads one stream.

Why is there no stream key in my TikTok?

TikTok decides which accounts get one. Its safety guide says creators must be at least 18 and that the follower requirement varies by market. No outside tool can grant access.

Do I need to paste the TikTok key every time?

Yes. The TikTok key changes between sessions. Before each live, take the current key from TikTok and paste it into StreamLive Pro.

Should I stream vertical or landscape?

Pick the shape of your main audience. Both networks receive the same picture, so a vertical stream suits TikTok and a landscape stream suits YouTube; keep important things in the middle either way.

Can I schedule a TikTok live in StreamLive Pro?

Not unattended. A scheduled broadcast can start YouTube on its own, but TikTok needs a fresh key from your account for each session, so someone has to paste it before the live.
