YouTube dual stream (Beta)

With YouTube’s dual stream, one broadcast can carry both a horizontal and a vertical version of your stream. YouTube shows each viewer the version that matches the format they’re watching in, so you reach desktop and mobile viewers without running two separate streams.

In SE.Live, you send each format from its own output and connect both to the same scheduled stream in YouTube Studio.

Beta feature

Dual stream isn’t fully integrated into SE.Live yet, so some steps below are manual. We’re working with YouTube to streamline the experience for both streamers and viewers.

Before you begin

• Install SE.Live and connect your YouTube channel.
• Enable live streaming on your YouTube channel.
• Create a vertical canvas for your vertical layout. YouTube channels get a horizontal and a vertical output in the Multistream dock. See Set up multistreaming.

Set up the stream in YouTube Studio

1. Create a scheduled stream

Open YouTube Studio from your profile menu.

Select YouTube Studio from your profile menu.

In the left menu, select Content, open the Live tab, and click Get started to schedule a stream.

Go to Content, open the Live tab, and click Get started.

2. Open the stream settings

Open your scheduled stream and select the Stream settings tab. Make sure Dual stream is turned on. It lets you connect a vertical stream from your encoder, or have YouTube generate a vertical cropped version for the Shorts feed.

Turn on Dual stream in the stream settings.

3. Set the vertical stream to use an encoder

In the vertical stream panel, change the source to Encoder and select your vertical stream key. The horizontal stream keeps using the default stream key.

Horizontal uses the default stream key. Set the vertical stream to Encoder and pick its key.

Go live from SE.Live

4. Enable the main output

In the Multistream dock in SE.Live, turn on your main YouTube output, the horizontal one with the desktop icon.

Turn on the horizontal output first. The vertical output, with the phone icon, stays off for now.

5. Start the stream in SE.Live

Start your stream in SE.Live. When prompted, choose the scheduled stream you created in step 1.

6. Enable the second output

In the Multistream dock, turn on the vertical output, the one with the phone icon.

7. Choose the same scheduled stream

When SE.Live prompts you to start the vertical output, choose the same scheduled stream you picked in step 5. Both outputs must use the same scheduled stream.

8. Go live in YouTube Studio

Once both outputs are connected, click Go Live in YouTube Studio. Each preview in YouTube Studio shows No data until its output connects.

End the stream

9. End the stream in YouTube Studio

End your broadcast in YouTube Studio first.

10. End the stream in SE.Live

Then end the stream in SE.Live.
