To stream in portrait mode with the Streamlabs Mobile app, choose the intended orientation and destination, configure a scene, and check the live preview before relying on it. The steps are similar on Android and iOS, but the available controls can differ by device and app version.
Portrait orientation shapes the video; it does not, by itself, guarantee placement in YouTube’s Shorts feed. For screen sharing, begin in the orientation you intend to use and keep the phone there, since rotating after the stream starts can make the shared image appear smaller on some destinations.
Check access and permissions first
Install Streamlabs Mobile from the app store for your phone and sign in. The names and positions of menu items can change, so use the current app interface rather than assuming every guide screenshot matches your version. Before building a scene, decide whether you want to show the phone’s camera, its screen, or both if the app and destination provide that combination.
For a camera stream, allow camera and microphone access when the app requests it. Without camera access, the app cannot show your camera image; without microphone access, it cannot capture your spoken audio through that input. If you denied a permission earlier, review the app permissions in your phone’s settings and return to Streamlabs. The exact labels differ between Android and iOS, but the aim is the same: allow only the access your chosen stream needs.
For screen capture, read the system prompt carefully. Screen broadcasting may use a phone-level capture control rather than the camera permission. Depending on the device, the prompt may also explain how audio is captured or whether system audio is available. Do not assume that a microphone toggle also includes audio from other apps. Make a short private test or check the destination preview to confirm what viewers will hear.
Prepare the phone as well as the app. Charge it, close apps you do not need, and suppress notifications that could expose private messages or interrupt a presentation. If the camera will be hands-free, a phone tripod with an adjustable holder can help keep framing steady, but it is optional. Check that the holder does not cover a lens, microphone, charging port, or side button you may need.
Create or choose a scene
Open the main menu and select Scenes. Create a scene for this particular stream or select one you have already arranged. A scene is the composition viewers receive: it may contain the camera, text, images, widgets, or other overlays. Keep the purpose of the stream in mind as you choose. A devotional session, a drawing demonstration, and a phone-screen tutorial need different amounts of visible space.
The Streamlabs editor is used in landscape view, even when you are preparing portrait content. That can make it tempting to arrange elements according to the editor’s wide canvas and assume they will all remain prominent when the camera output is vertical. Preview the scene at the actual orientation and destination where possible. Treat anything close to the far left or right edges with caution: the editor guidance describes those side regions as places where widgets may appear beside the camera image in its portrait-camera behaviour, but this is not a promise that every destination receives an identical layout.
Keep scenes simple enough to inspect. If you use a title, place it where it remains readable without covering a face, instrument, scripture, or the part of the screen being demonstrated. If a scene has several layers, hide or remove anything that is not useful. A crowded composition is harder to check on a small phone display and can obscure the content that matters.
If you are making a recurring format, consider saving a distinct scene for portrait and another for landscape rather than repeatedly resizing one layout. This is useful when, for example, you alternate between a vertical phone-camera greeting and a horizontal video or presentation. Scene selection does not alter the destination’s technical rules, but it reduces the chance of going live with a title or overlay in the wrong place.
Arrange overlays for the viewer’s frame
Place the primary subject first, then position text and other elements around it. With a camera stream, frame the person or object inside the portrait image before adding decoration. With screen capture, identify the central area viewers need to read, such as a menu or lesson page, and make sure labels do not sit on top of it. Think about where a viewer’s hand or device interface might cover part of the screen as well.
Small text that looks acceptable while editing may be difficult to read on a phone. Use short labels, clear contrast, and enough empty space around essential words. Avoid putting a running ticker, logo, or decorative border across the top or bottom without checking how the destination preview presents the full image. Some viewers may see controls around the video, and a layout that reaches the edges can feel cramped even when no part is technically cropped.
For portrait camera streams, Streamlabs’ editor guidance notes that black side bars can appear beside the camera image and that widgets placed far to the left or right may occupy those areas. That is a layout observation for the described editor behaviour, not a guarantee about every output path. If a side widget contains information viewers must read, verify it on the intended destination rather than designing around an assumed 16:9 canvas.
A practical check is to review the scene at the size viewers are likely to use. Look for three things: whether the subject is recognisable, whether essential text can be read, and whether an overlay hides an important gesture or screen control. Ask someone else to look at the preview on a separate phone if you can. This often catches a title that is technically present but too small to be useful.
If the project later becomes a recorded or continuous programme, the content itself needs separate preparation. For example, a channel built around recurring audio or video may benefit from a plan for looping podcast episodes in OBS, while creators with pre-recorded material can review how a 24/7 channel can run from a home computer. Those are different workflows from a phone-based live scene; the useful point here is to keep the scene and the programme format in view together.
Review streaming settings before going live
Open Streaming Settings and inspect the available video, audio, camera, and screen-capture options. Streamlabs documents controls such as resolution, frame rate, bitrate, audio input, camera choice, and orientation-related options, but not every control is available on every phone or operating system. Use the options your installed app actually shows rather than following a setting list copied from another device.
Choose a resolution and frame rate your phone and connection can sustain. There is no single setting that suits every camera, network, or destination. A higher output demand can make a weak connection less forgiving; a lower one may be a reasonable test when you see repeated drops or stuttering. Make a brief test and observe the app’s status and destination preview. If the image freezes, simplify the scene and reduce competing network activity before changing several settings at once.
Audio deserves its own test. Select the intended microphone input if the app offers a choice, then listen for speech level, background noise, and any echo. If you are narrating a screen demonstration, check that your voice is audible while the captured image remains legible. If you are streaming music or another programme, confirm that the audio source is permitted for your use and that it is not unintentionally doubled by both device and microphone capture.
Confirm the account and destination as well. Streamlabs’ mobile guide lists several supported platform connections, while the app’s actual options can change; check the installed version before planning around a destination. Choosing portrait does not require multistreaming. Streamlabs documents mobile multistreaming as an Ultra feature, which is a separate decision from using a vertical layout. Review the current app information before relying on any subscription feature or destination combination.
A useful comparison is not “which setting is best” in the abstract, but which workflow fits the material and viewer:
| Choice | Works well when | Check before starting |
|---|---|---|
| Portrait camera | You are speaking to viewers or showing a tall subject | Face or subject framing, microphone input, and overlays at the sides |
| Portrait screen share | The phone screen itself is the lesson or demonstration | Start orientation, readable screen detail, and capture audio behaviour |
| Single destination | You want a straightforward setup for one platform | Account connection, privacy, and the destination preview |
| Multiple destinations | You have a reason to reach separate platforms at once | Current app support, subscription requirements, and a layout that works in each place |
Keep a note of settings that worked for your own phone and network, but treat it as a starting point rather than a guarantee for the next location. A home Wi-Fi connection, a crowded venue, and mobile data can behave differently. If you plan long sessions or recurring broadcasts, test at the place and time you intend to go live.
Start a portrait camera stream
Select the camera as your source, choose the destination, and set the phone upright before you begin. Check the camera preview for framing, focus, lighting, and any background detail you do not want to show. If the app offers a front or rear camera choice, use the preview to confirm which one is active. A tripod or stable surface can make the framing easier to maintain, especially if you need both hands for an instrument or demonstration.
Review the scene one last time in the portrait composition. A face positioned near the top of a wide editor canvas may be cropped or feel off-centre once the camera view is vertical. Place important text and widgets where they do not compete with the face or obscure the activity. If you are showing an object, leave enough room for your hands to enter the frame without covering the subject.
Start the stream from the app and then verify the destination’s live preview. Do not rely only on the local preview: check the actual broadcast view for orientation, sound, and overlays. If the destination offers a delay before the public stream appears, allow it to load and confirm that it is the intended account and stream. If anything is wrong, stop and correct the scene before sharing the link.
For a YouTube stream, vertical appearance and discovery placement are separate questions. YouTube Help describes vertical live viewing and discovery through Shorts, but a vertical stream sent through third-party software may not be identified for the Shorts feed. Confirm current YouTube behaviour and examine the live view; do not tell viewers they will find the broadcast in Shorts merely because the phone is upright. If you also publish edited highlights, this guide to turning a Twitch clip into a YouTube Short covers a separate format, not a setting that changes a live stream’s placement.
Share the screen in portrait
For a screen-share stream, first decide what viewers need to see and whether the app offers the right capture option for your device and destination. Open the relevant app or page before going live, dismiss private notifications, and position the content so that its important details fit a tall frame. If the material is a wide spreadsheet or slide, portrait may make text too small. It can be better to simplify the material, zoom into one section at a time, or choose a horizontal workflow when the whole width is essential.
Set the phone to portrait before starting the screen-share broadcast, then keep it there during the stream. Streamlabs has documented a case in which a stream begins in landscape and the phone is then rotated to portrait; the output can remain locked to landscape while the display turns, making the shared image appear smaller. The behaviour is not necessarily the same on every device or destination, so check current app guidance and test your exact setup.
Do not assume that rotating back and forth will preserve the same image size. If you need to switch orientation, end the stream and start again in the intended orientation after checking the scene and capture preview. That is less disruptive than discovering mid-explanation that the shared screen has become hard to read. Streamlabs’ support article describes a workaround for Twitch or Trovo and reports no workaround for YouTube and other platforms at the time of that article; because issue status can change, consult the current support page rather than treating that as permanent platform behaviour.
Screen capture also raises different audio questions from a camera broadcast. Decide whether viewers should hear your narration, the app’s audio, or both, and check the capture prompt and available settings. Play a brief sample and listen from the destination side if possible. A phone can mute notifications yet still capture an alert visually, so suppress them before sharing any screen that might reveal personal messages or account details.
Understand destination behaviour and orientation changes
Portrait is a shape for the outgoing video; it is not a universal switch for every platform feature. YouTube has more than one vertical-live workflow. Its Help documentation describes a Live Control Room path where horizontal and vertical outputs can be configured together, including a third-party encoder route that uses matching stream keys and RTMP(S). That specific workflow should not be confused with simply turning a phone sideways or upright in Streamlabs Mobile.
YouTube Help states that, by default, live streams from the Live Control Room go live in both horizontal (16:9) and vertical (9:16) formats at the same time. The scope matters: this describes streaming from the Live Control Room, not a guarantee for a Streamlabs Mobile stream. Read the current YouTube live-streaming guidance for the workflow you plan to use. Also consult Streamlabs’ mobile live-streaming guide and screen-share troubleshooting note when the interface or orientation behaviour differs from what you expect.
The practical distinction is this: first confirm the stream’s aspect and composition in the destination preview; separately check how that destination surfaces or recommends the stream. A vertical third-party broadcast may display as a vertical video without appearing in the Shorts feed. Neither an app setting nor an upright phone can guarantee a discovery surface, and YouTube can change how its viewing experiences work.
If your programme needs a horizontal version as well as a vertical one, plan for two compositions rather than assuming the same scene will suit both. A title at the edge of a portrait frame can be lost or become awkward in a wide frame, while a horizontal layout may leave a portrait viewer with unused space. YouTube’s Live Control Room or an encoder-based workflow may be more appropriate when you specifically need its documented dual-output path; a direct mobile stream may be simpler when a single phone-shaped view is enough.
Check the selected account, audience settings, title, and destination before you send viewers to the live page. If you are building a longer-running channel rather than making a one-off phone broadcast, there are other operational questions too: archiving a 24/7 sleep-sounds stream and planning a continuous Sanskrit mantra playlist involve continuity and recording choices beyond portrait framing.
Make a final pre-live check
Before pressing Go Live, verify four things in sequence: the chosen source is correct, the scene is readable in portrait, audio is coming from the intended input, and the destination is the account you mean to use. Then watch the destination preview for a moment after starting. This catches a common class of mistakes that a settings screen cannot show, such as a missing overlay, silent microphone, or screen capture that is too small.
If a stream drops, avoid changing several settings at once. Note whether the app reports a connection issue, whether audio continues, and whether the preview recovers. For a recurring programme, keep a simple record of the phone model, operating system, app version, destination, and conditions under which the issue occurred. That information makes it easier to compare a later test and to explain the problem to support without assuming the cause.
A phone is useful when you need a mobile camera or want to present the phone’s own screen. It is less convenient when you need a carefully controlled continuous broadcast that should run after the phone is put away. For that specific problem, StreamNeo removes the need to leave a phone or computer running by turning an uploaded video into a YouTube live stream that you start with your channel’s stream key.

FAQ
How do I stream in portrait mode with the Streamlabs Mobile app?
Grant the access your chosen source needs, choose or create a scene, select the destination, and set the phone upright before you start. Review the portrait preview and test the audio and overlays at the destination, because controls and output behaviour can differ across devices and platforms.
Does portrait mode put my YouTube live stream in the Shorts feed?
No. Portrait orientation can produce a vertical-looking stream, but it does not guarantee Shorts-feed placement. Check the current YouTube workflow and the destination preview, and avoid promising viewers a particular discovery location.
Should I rotate my phone after starting a screen-share stream?
It is safer to set the intended orientation before starting and keep it fixed. Streamlabs has reported that rotating after a landscape start can leave the output locked in landscape and make the shared image look smaller on some destinations; verify current behaviour for your device and platform.
Is the setup identical on Android and iOS?
The broad process—permissions, scene, settings, destination, and preview—is similar, but available controls can differ by operating system and app version. Follow the options actually shown on your phone and check Streamlabs’ current support guidance if a setting is missing.
