You can stream vertical video on YouTube from the mobile app, or create horizontal and vertical versions together in YouTube Studio’s Live Control Room. If you use the dual-format workflow, choose the vertical layout before you start the broadcast because YouTube does not let you add the vertical format after a stream has begun.
The right method depends on the job. A phone is practical for a quick portrait update, while Live Control Room is better when viewers may watch on both a mobile screen and a computer or television. The vertical version is a centre crop by default, but YouTube also provides fit-to-phone-width and stacked layout choices.
Choose between the mobile app and Live Control Room
The YouTube mobile app is the shorter route to a portrait live stream. In the app, open Create, choose Live, and decide whether the phone will remain in portrait or landscape orientation. This works well for a presenter speaking directly to the camera, a local update from the street, or a short devotional broadcast where the phone itself is the production setup.
The trade-off is control. Your framing, sound, lighting, battery and internet connection all depend on the phone and the immediate location. There is no separate landscape production feed for viewers using a desktop or television. You are choosing a simple, phone-led workflow rather than a two-format programme.
Live Control Room is the better route when one event needs to serve different screens. YouTube can create a 16:9 horizontal version and a 9:16 vertical version together. Viewers browsing the Shorts feed on a mobile device can see the vertical presentation, while other viewers receive the horizontal version. The stream uses one URL, one go-live notification and shared live chat.
That shared arrangement is useful, but it does not make the two views identical. A speaker may look well framed on a phone but leave too much empty space on a television. A wide devotional scene may work in landscape but crop out the singer, lamp or text when converted to portrait. Plan the important visual area before you choose the workflow.
For a prerecorded channel that needs to keep running while your computer is switched off, StreamNeo removes the need to leave a local machine operating throughout the broadcast. This article, however, is about YouTube’s native mobile and Live Control Room choices, so use those controls to decide how a live camera or encoder should be framed.
Check eligibility and plan the format first
Do not begin with camera settings. Begin by checking whether the channel can use the intended live-streaming method. YouTube’s general guidance says the channel must be verified, must not have had live-streaming restrictions during the previous 90 days, and the creator must be at least 16. Mobile streaming has additional conditions, including a subscriber requirement listed by YouTube.
The current requirements are described in YouTube’s live-streaming overview and its mobile live-streaming guidance. Read the official pages before scheduling an event because eligibility rules and Studio surfaces can change. If live streaming has only just been enabled, YouTube says first-time activation may take up to 24 hours.
Choose the audience before choosing the canvas. A local news presenter who reads messages and shows a wide street scene may need both formats. A person demonstrating a recipe from close range may be able to work in portrait alone. A bhajan or naam simran channel with a fixed camera, altar and lyric panel needs to check whether those elements remain visible after a centre crop.
Write down the intended format in plain language. For example:
- Portrait only: one phone remains upright, with the presenter’s face and upper body inside the frame.
- Dual format: landscape serves desktop and television viewers, while portrait serves mobile viewers in the Shorts feed.
- Encoder dual format: a production system sends separate matching feeds for the two orientations.
This decision matters because vertical output is not an extra switch that can be safely added halfway through the broadcast. In Live Control Room, configure the dual-format stream and inspect the vertical preview before going live. If you start with only the horizontal version, YouTube says the vertical format cannot be added after the stream has started.
Think about text as well as people. A title card designed across the full width of a 16:9 frame may be unreadable or partly missing in portrait. Keep names, prices, prayer text and lower-thirds close enough to the central area that the portrait composition can retain them. If the information only makes sense in a wide frame, a landscape-first stream may be more honest than forcing it into a mobile crop.
Set up horizontal and vertical versions in Live Control Room
On a computer, open YouTube Studio, choose Create, then Go live, and create or select the scheduled stream. In the Manage area, select the stream and open the vertical preview. YouTube’s dual-stream workflow creates both orientations by default, so the important work is checking how the source appears in each one before the audience sees it.
Use Edit layout in the vertical preview. You can choose the crop or layout, then adjust zoom and position where the controls allow it. The purpose is not to make the portrait version look like a second camera angle. It is to decide which part of the horizontal source deserves priority when the available width becomes narrow.
A useful test is to mark three zones in your source scene:
- The subject that must remain visible, such as a face, product or altar.
- Supporting information, such as a logo, ticker or lyric line.
- Details that may be sacrificed, such as empty background or decorative side panels.
Place the first zone near the centre of the landscape composition. Keep the second zone away from the extreme left and right edges. Then use the preview to see whether the portrait view preserves the intended order of information.
The dual workflow uses one live URL and one notification rather than asking you to promote separate events. Chat is shared between the formats. That simplifies promotion, but remember that the viewing experience still differs. A message written for a horizontal layout may not align with what a person sees in portrait.
You can also use a third-party encoder when you need encoder-based production. YouTube’s workflow supports sending a horizontal feed and a vertical feed using RTMP or RTMPS and a second stream key. This is a more involved setup: each key must receive the matching orientation, and the two feeds must represent the same event.
Do not assume that every encoder can create or deliver both orientations. Check the documentation for the exact software or hardware you intend to use, then test it with an unlisted stream. If your encoder only produces one feed, it may be suitable for a single-format broadcast but not for YouTube’s dual-format arrangement.
Choose centre crop, fit or stacked layout
YouTube’s default vertical treatment is a centre crop. It takes the horizontal source and uses the central portion for the portrait view. This is quick and often acceptable when the important subject is already in the middle, but it can remove people, captions or objects positioned towards the sides.
Centre crop is usually the cleanest choice for a single subject. A presenter standing centrally, a close-up of a singer, or a product held in front of the camera can survive this treatment with little adjustment. It becomes problematic when two people stand apart or when a wide scene carries information across its entire width.
Fit to phone width preserves more of the source within the portrait frame, though it may introduce unused space or reduce the apparent size of the subject. This can be preferable for a landscape scene where losing the edges would remove useful context. Check how YouTube presents the surrounding area rather than assuming that preserving the whole source will automatically look polished.
Stacked layout gives you another way to organise the available portrait space. It can place source material in a portrait composition rather than simply cutting a tall window from the middle. This may suit a presenter and supporting visual, or a live camera view paired with information that should remain visible below or above it.
The choice is a communication decision, not just a technical one. Consider this example: a local shop owner demonstrates a machine while a price panel sits on the right side of the landscape frame. Centre crop may remove the price. Fit may keep the panel but make the demonstration smaller. A stacked layout may preserve both by giving the demonstration and the supporting information separate areas.
Use the layout canvas before starting the stream. YouTube says the layout can continue to be adjusted while live when it has been edited in the canvas, but do not treat that as a substitute for a proper preflight. A change made during a busy broadcast can alter what viewers are reading or watching. Prepare the likely layout in advance, then make only deliberate corrections.
| Layout | Keeps most useful when | Main risk | Good starting choice |
|---|---|---|---|
| Centre crop | One subject is near the middle | Side content disappears | Presenter, singer or close product view |
| Fit to phone width | The whole wide scene matters | Subject may appear smaller or leave unused space | Street view, room view or group scene |
| Stacked | Two visual elements need separate priority | Composition needs more preparation | Presenter plus graphic, product or supporting view |
There is no universal best layout. Watch the preview at the size your viewers will use and select the arrangement that keeps the essential message understandable.
Understand how the vertical version is framed
A vertical screen is taller and narrower than a standard landscape player. The portrait version therefore changes the relationship between people, objects and text even when the source video has not changed. A person who is centred in a wide frame may become too close to the top or bottom once the crop is adjusted.
Start with headroom. Leave enough space above a speaker’s head for the portrait crop, but avoid placing the face so low that captions or controls compete with it. If the camera is fixed, record a short test and inspect both previews rather than judging the composition from the camera’s own screen.
Groups require particular care. Two people standing side by side may fit in landscape but force one person out of the centre crop. Move them closer together, use a fit layout, or consider a stacked arrangement. Do not wait until viewers report that one participant is missing from the vertical version.
Text is another common failure. A ticker that runs from edge to edge can be cut at both ends. A large logo in a corner may disappear, while a small logo near the centre may compete with the speaker. Put essential labels in a safe central area and use fewer words when the information must be readable on a phone.
Portrait viewers also encounter the stream in a different context. YouTube says vertical live video can appear as people browse the Shorts feed in the mobile app, giving the broadcast a full-screen vertical viewing experience. That does not mean every feature available around a standard live player is present in the vertical feed.
YouTube’s feature comparison notes differences including the availability of clickable links in chat or the channel description, live pre-roll and mid-roll ads, Premieres and Live Redirect in that feed. These feature surfaces can change, so check the current YouTube comparison guidance before planning a campaign around a particular interaction.
The practical lesson is to make the video understandable without requiring a link or description. Put the essential instruction in the spoken presentation or visible frame, and tell viewers where to find more information only after checking which surfaces the intended audience can use.
Check encoder and stream-key requirements
If you use an encoder, prepare the stream in Live Control Room before sending the feeds. In the Stream tab, YouTube’s documented workflow lets you change the vertical preview from Auto to Encoder, choose RTMP or RTMPS, and select the second stream key for the vertical version.
A stream key is a credential that tells the encoder where to send the feed and allows YouTube to accept it. Treat it like a password. Do not publish it in a tutorial screenshot, paste it into an untrusted message, or reuse it carelessly across unrelated productions. If you suspect it has been exposed, follow YouTube’s current key-management process rather than continuing with a compromised key.
The horizontal key must receive the horizontal feed and the vertical key must receive the portrait feed. Label them clearly in your encoder and confirm the canvas orientation for each output. A portrait-shaped crop sent to the landscape key, or the same landscape feed sent to both keys, can produce a confusing preview even when the connection itself is working.
YouTube’s encoder preparation guidance recommends setting up in advance, starting the encoder before the scheduled event, reviewing the preview and checking the result on mobile. Follow the exact current instructions in Studio because the names and positions of controls may change.
Network planning matters more when two feeds are involved. YouTube’s guidance recommends leaving 20% upload bandwidth headroom beyond the combined stream bitrate requirement. Treat that as planning guidance, not a guarantee. Shared household uploads, Wi-Fi changes, background backups and mobile-network variation can all reduce the capacity available to the encoder.
If you are running from a spare computer, read the practical advice in how to run a YouTube radio stream from a spare PC before relying on it for a long event. For OBS users, the reconnect settings guide can help you think through recovery behaviour, but it does not replace testing the actual dual-output workflow.
A local encoder also creates a local failure point. Power loss, operating-system updates, a sleeping computer or a router restart can interrupt the broadcast. YouTube’s official encoder checklist is useful for checking the production path, while a separate stream-disconnection troubleshooting guide can help you investigate interruptions after a test.
Test the viewing experience before going live
Use an unlisted stream to test the actual path, not just the camera preview. Check what the horizontal viewer sees on a computer and what the vertical viewer sees on a phone. Confirm the face, product, altar, text and any lower-third remain where you expect them to be.
Lock the phone’s rotation before a mobile broadcast. YouTube recommends deciding the orientation and locking rotation so an accidental turn does not change the shot. Charge the phone, enable Do Not Disturb, and consider an external battery pack for a longer mobile session. YouTube’s mobile guidance gives a rough estimate of 1% battery use per minute of streaming, but treat that as planning guidance rather than a result guaranteed for every phone.
Test sound separately from picture. Listen through the phone or another device for echo, wind, clipping and background noise. A devotional stream with a clean image but distorted vocals is not ready, and a local update with clear speech but unreadable framing still needs work.
For an encoder, send the feeds early enough to inspect the previews. YouTube recommends preparing the encoder at least two hours before an event and starting it at least 15 minutes before the scheduled start. Confirm that the preview is moving, the audio meter responds, the correct orientation is assigned to each key, and the event opens on mobile.
Make a simple test checklist:
- Is the channel eligible for the selected workflow?
- Did you choose portrait-only or dual format before starting?
- Is the vertical preview using the intended crop or layout?
- Are faces, products and essential text visible in portrait?
- Does the horizontal version still work on a wide screen?
- Is the phone charged, rotation locked and protected from interruptions?
- Are the encoder outputs and stream keys matched correctly?
- Does the unlisted stream play with stable picture and sound on mobile?
If the test exposes a framing problem, correct the camera position or layout before publishing. Do not assume viewers will simply rotate their phones or tolerate missing information. A short test is cheaper than discovering after launch that the headline, speaker or price panel exists only outside the portrait crop.

FAQ
Can I stream vertical video directly from the YouTube app?
Yes. Open the YouTube mobile app, choose Create, then Live, and set the phone’s orientation before starting. Check mobile eligibility first, lock rotation and test the connection, picture and sound with an unlisted stream.
Can YouTube show horizontal and vertical versions at the same time?
Yes, Live Control Room can create 16:9 horizontal and 9:16 vertical versions for the same event. They use one URL, one notification and shared chat, but you must configure the vertical format before the stream starts.
What is YouTube’s default vertical layout?
The default is a centre crop of the horizontal source. You can instead choose fit to phone width or a stacked layout, then adjust the framing in the vertical preview so important people and information remain visible.
Can I add vertical format after going live?
No. YouTube says the vertical format cannot be added after the stream has started. Decide on portrait-only or dual-format output during setup, then inspect both previews before you begin.
