How to stream on YouTube and Rumble at the same time

Short answer: Can you stream on YouTube and Rumble at the same time? Yes. YouTube supports going live with the same content on several platforms at once, and Rumble says creators can stream to Rumble while restreaming to other platforms.

YouTube brings search and replays that keep working for you after the stream ends; Rumble brings an audience that only partly overlaps with it. Both openly allow streaming to other platforms at the same time, so one OBS can feed both.

Here are two ways to do it with Multistream: Multistream Cloud, where OBS uploads once and the cloud sends the stream to YouTube and Rumble, and the free Multistream app, where your PC sends both copies. After that: keys that stay the same on both platforms, and settings that suit both.

Method 1: Multistream Cloud (one upload for every platform)

Multistream Cloud takes one stream from OBS and sends a copy to YouTube and Rumble, and to up to 12 platforms in all. Your internet only uploads that one stream, so adding a platform doesn't need a faster connection. It comes with Pro, $10/mo.

  1. Create your Multistream account, then get Pro on your Account page.
  2. In the Studio's setup guide, on Where do your viewers watch you?, click Add a platform and add each one:
    • YouTube: click Sign in with YouTube and pick your channel's Google account. Multistream Cloud then starts your YouTube broadcast by itself, so it doesn't sit in preview.
    • Rumble: paste the Stream URL and stream key from Rumble's streamer configuration. Create a Static Stream Key in your Rumble account so it stays the same.
  3. Install Multistream for OBS (Windows 10 or 11, or a Mac as a beta; OBS 31.1 or newer) and open OBS. The Multistream dock opens on the right.
  4. In the dock, click Sign in with your browser and approve it.
  5. The dock's pre-flight check looks at your OBS settings, Multistream Cloud, your platforms and where OBS sends. If OBS isn't sending to Multistream yet, click Point OBS at Multistream.
  6. Click Go live on 2. After a 3, 2, 1 countdown, OBS starts streaming and YouTube and Rumble go live.

If OBS or your internet drops, Pro keeps your platforms live on your BRB clip for up to 30 minutes, and when OBS is back you carry on in the same broadcast, with the same chat. Turn it on under Disconnect protection.

Method 2: the free Multistream app (from your own computer)

The free Multistream app for Windows and Mac can send the copies from your own computer instead. Your upload then carries one copy for each platform, and if your PC's internet drops, your platforms drop with it. Run the app's Speed test first to see what your connection can carry, or work it out with the free upload calculator.

  1. Download the Multistream app for Windows 10 or 11, or macOS 11 or newer, and open it.
  2. Go to Multistream → Go live and set Send from the cloud or from this PC to This PC.
  3. Open Setup guide and click Add a platform for YouTube and Rumble. Twitch, YouTube and Kick accounts you've connected in the app add in a click; the others take their stream key.
  4. Install Multistream for OBS and open OBS. Without Pro, the Multistream dock sends your stream through the app on this PC, so keep the app open.
  5. Click Go live on 2 in the dock. Your PC uploads one copy for each platform.

If this happens: the app keeps saying Waiting for OBS to go live after you press Start Streaming. Open OBS's Settings → Stream again and check the server and key match the app's Setup guide, then make sure the app is still open. If you open the app a second time, it just brings the first window forward, so you never end up with two. If an app update stops partway, the app says why and offers Try again.

Good to know for YouTube and Rumble

Turn on live streaming on YouTube first. Your channel needs to be verified, and the first time YouTube can take 24 hours or more to turn on live streaming, so do it a day ahead (YouTube Studio → Create → Go live).

No stuck preview. Add YouTube to Multistream Cloud with Sign in with YouTube and it starts your YouTube broadcast by itself. Without that, turn on Auto-start in YouTube Studio, or YouTube waits for you to press Go live there.

Make both keys stay the same. On YouTube, create a custom key under Create → Go live, on the Stream tab, with Create new stream key. Rumble gives each stream its own key (under Get the streamer configuration after you fill in the Go live form) unless you create a Static Stream Key in your Rumble account. Then you paste each key into Multistream once.

Both allow streaming elsewhere. YouTube says you can go live with the same content on several platforms at once, as long as your accounts there are in good standing. Rumble says creators can stream to Rumble while restreaming to other platforms.

One set of settings for both. Every platform gets the same stream OBS sends, so pick settings both accept. YouTube recommends H.264 and a keyframe every 2 seconds (never more than 4); Rumble recommends a keyframe every 2 seconds too, AAC audio at 128 kbps and 8,000 kbps at most. For 1080p at 60 fps, YouTube's range is 6,000 to 17,000 kbps and Rumble's is 4,000 to 6,000 kbps, so around 6,000 kbps fits both.

Check your upload before going free. YouTube suggests an upload speed of 1.5 to 2 times your combined bitrate. With the free app, your upload carries a full copy for each platform, so run the app's Speed test or the free upload calculator first. With Pro, OBS uploads one stream however many platforms you add.

Read both chats in one window

Chat is separate from your video, but the free app can put YouTube and Rumble chat in one list so you answer both from one place. In the app, open Connections in the top bar: for YouTube, click Authorize with YouTube and sign in; for Rumble, paste the link from Live Stream API in your Rumble account. YouTube chat shows once your YouTube stream is live, and Rumble chat only fills while your Rumble stream is live. See all your chats in one window for the steps.
