How to Stream Vertical Live Video on YouTube

To stream vertical live video on YouTube, send a 9:16 feed — 1080×1920 or 720×1280 — from an encoder or cloud streaming service using your normal YouTube stream key. Phones show it full screen, and YouTube can surface vertical live streams to people scrolling short-form video.

The settings take minutes. The decisions around them — whether vertical fits, how to frame for a phone, and whether you also need a horizontal version — take more thought.

Key takeaways

• Send a true 1080×1920 output, not a horizontal frame with black bars.
• Keep faces and text centered; phone apps overlay the edges.
• Vertical suits phone-first, single-subject content; horizontal still wins on TV and desktop.
• Horizontal and vertical versions are two separate streams.

How YouTube handles a 9:16 live stream

YouTube's live system accepts vertical video over the same ingest as any other stream. You don't need a special key or app; the orientation comes from the video you send. On a phone, a vertical stream fills the screen. On desktop and TV, it plays in the middle with empty space on either side.

YouTube has also shown vertical live streams to mobile viewers in its short-form feed, where people can swipe past or tap in. How often that happens, and for whom, is decided by YouTube's systems and changes over time, so treat it as a possible bonus rather than a promise. Check YouTube's current creator updates.

Everything else stays familiar: live chat, titles, descriptions and the channel requirements in our YouTube live requirements checklist.

Resolution, frame rate and bitrate for vertical

Treat vertical like its horizontal equivalent turned on its side:

• Resolution: 1080×1920 for full HD, or 720×1280 if bandwidth is tight.
• Frame rate: 30 fps for talk, music and product content; 60 fps only for fast motion.
• Bitrate: about 4,500–6,000 kbps at 1080×1920 and 30 fps, or 3,000–4,000 kbps at 720×1280. Check YouTube's current recommendations.
• Encoding: H.264, constant bitrate, 2-second keyframe interval, AAC audio at 128–160 kbps.

The classic mistake is a 1920×1080 canvas with a vertical video pillarboxed inside it. YouTube then receives a horizontal stream with black bars on both sides. Set the output itself to 1080×1920, and confirm the preview looks vertical before going public. There's more on choosing settings in our resolution and frame rate guide.

Framing for a phone screen

A vertical frame is narrow, and the mobile app covers parts of it. Design with that in mind:

• Keep the middle for what matters. Faces, products and key text belong in the central band.
• Leave room at the bottom and right edge. Chat, the comment box and action buttons commonly sit there.
• Use bigger text. Captions that look fine on a monitor are unreadable on a phone; roughly double their size.
• Recompose rather than crop. Cropping a wide shot often cuts people or products in half. Reframe in your editor instead of letterboxing a 16:9 video into a 9:16 frame.

For talk or tutorial content, a stacked layout works well: the main video in the upper half and a caption or topic card beneath it, above the overlay zone.

When vertical beats horizontal, and when it doesn't

Vertical is a strong choice when most viewers are on phones and the subject is naturally tall or single-focus:

• One person talking to camera, interviews and call-in formats.
• Product demos, unboxings, and crafts or cooking filmed from above.
• Highlights from content that already performs well as short-form video.
• Calm scenes meant to sit on a phone like a live wallpaper.

Horizontal is still better for gameplay, wide scenes, panels with several people, slides and screen shares, and music or ambient channels people leave playing on a TV. If your analytics show most live watch time comes from TV or desktop, a vertical-only stream shrinks the picture for the viewers who matter most. If you can't decide, run both — just know that means two streams.

Running horizontal and vertical versions side by side

A single stream has one orientation. To serve desktop and mobile viewers with properly framed video, run two streams: a 16:9 version and a 9:16 version, each with its own source files and its own YouTube broadcast.

• Two broadcasts, two chats. Viewers split between them, so moderate both and link each from the other's description.
• Distinct titles. Mention the format where it helps viewers pick the right one.
• Two exports per video. Build a real vertical cut, not just a crop.
• More vertical destinations. The 9:16 stream can also go to TikTok if your account has LIVE access; see TikTok LIVE vertical settings.

Check YouTube's help pages for any current limits on running more than one live stream on a channel at the same time.

Running a vertical 24/7 YouTube stream with StreamHouse

StreamHouse offers a vertical 9:16 output preset next to horizontal 16:9, at 720p or 1080p and 30 or 60 fps depending on your plan. To run a vertical stream:

1. Export your videos in 9:16 — StreamHouse doesn't reframe or edit video — and upload them to the media library.
2. Create a stream with the vertical preset and build a looping playlist.
3. Connect your YouTube channel and pick a thumbnail from your library, or paste a stream key instead.
4. Press Start or schedule it. The stream runs in the cloud around the clock, with your computer off.

Need the horizontal version too? Create a second stream with the 16:9 preset; it uses a second stream slot. Plan sizes are on the pricing page.

Frequently asked questions

What resolution should a vertical YouTube live stream be?

Use 1080×1920 for full HD, or 720×1280 on a slower connection. Set the encoder's output to that size so YouTube receives a true 9:16 stream rather than a horizontal frame with black bars on each side.

Do vertical live streams show up in the YouTube Shorts feed?

YouTube has shown vertical live streams to mobile viewers in its short-form feed, but it decides when and to whom. Treat it as a possible source of discovery, not a guarantee, and check YouTube's current creator updates.

Can I go live vertically from the YouTube mobile app instead?

Yes, the app can go live from your phone's camera, though YouTube sets eligibility rules for mobile live that change over time. Encoder and cloud streaming use a stream key instead, which suits recorded or 24/7 content better.

Can one live stream be both horizontal and vertical?

No. A stream has one output orientation. To serve both desktop and phone viewers well, run a 16:9 stream and a separate 9:16 stream, each with properly framed source videos and its own YouTube broadcast.
