You can send portrait and landscape versions of a live programme at the same time, but the available routes do not all create the two pictures in the same way. Some derive portrait from a crop of a landscape scene; others let you arrange separate canvases, and some lock orientation choices before you go live.
Start by checking where you need to publish, then decide whether one shared composition can survive both shapes. If the portrait framing needs its own camera position, text placement or overlays, choose a workflow that gives you that control and test both outputs before the scheduled broadcast.
What simultaneous portrait and landscape means
Portrait and landscape usually refer to different frame shapes: 9:16 and 16:9. YouTube documents dual-format live streaming in those aspect ratios. A simultaneous stream is not simply one video rotated on a phone: the service or streaming software needs to produce an image suited to each shape and route it to the relevant destination or live event.
That image can be made in a few ways. A system can take one landscape feed and crop its centre into portrait; it can adapt a single set of sources to two shapes; or it can let you build a portrait scene and a landscape scene separately. These approaches affect what viewers can see. A wide shot may crop out a person standing to one side, while a title designed for the wide frame may be too small or clipped in a narrow one.
The phrase “at the same time” also needs a destination check. A tool may support two output orientations but not every platform, account or routing combination. A platform-native feature may create formats for that platform, whereas a third-party studio may route channels according to its own supported integrations. Do not infer from a dual-output switch that every connected destination receives both versions.
Choose between a shared crop and separate canvases
A shared crop is usually the simpler choice when the important subject stays near the middle and the same content works in both shapes. For example, a teacher speaking to camera with a centred whiteboard may be legible in a centred portrait crop. A wide panel discussion, scrolling ticker or gameplay HUD is less likely to survive it intact.
Separate canvases take more preparation, but they allow you to make different framing decisions. You might keep a full-width camera and lower-third in landscape, then use a closer camera crop and shorter caption in portrait. This matters especially when the vertical viewer would otherwise receive a narrow strip of a much wider composition.
| Choice | What it does | Useful when | Main trade-off |
|---|---|---|---|
| Shared centre crop | Derives portrait from the horizontal picture | The subject is centred and overlays are minimal | You cannot independently reposition cropped content |
| Synced, adjustable layout | Carries sources between layouts, with some repositioning | You want one source set adapted to two shapes | The layouts are related rather than fully independent |
| Separate canvases or scenes | Lets you place and size sources differently by orientation | Framing and readable overlays matter in both formats | More setup and preview work; routing may differ by destination |
Before choosing software, make a simple list of the destinations and the image each needs. Then inspect what happens to the parts that carry meaning: faces, product details, lyrics, captions, scores or a news ticker. If the horizontal layout is already a carefully composed scene, do not assume a crop will preserve it. The OBS settings guide for an ambient music stream is a useful reminder that scene composition and output settings need to suit the content, not just the encoder.
YouTube Live Control Room dual stream
YouTube's Live Control Room offers a native dual-stream route. In YouTube Studio, open Live Control Room and the stream settings, then enable Dual stream. The documented Auto option creates the portrait version by centre-cropping the horizontal live feed. This avoids building a second composition, but the crop is the key limitation: anything outside the central vertical area will not appear in portrait.
YouTube also documents an encoder route. Instead of Auto, select Encoder and add a second stream key for the vertical output. That route is for an encoder producing the relevant formats, rather than assuming YouTube can invent a separately arranged portrait scene from your horizontal output. Keep track of which key belongs to which format and verify the matching output before the event.
The encoder-based dual-stream feature is not available to every creator yet; YouTube says availability is rolling out. There is also a live-setting constraint: YouTube says the vertical stream cannot be removed once the broadcast has started. Treat orientation and stream-key selection as preflight decisions, not adjustments to make casually after going live.
For a centred speaker or a simple ambient visual, Auto may be sufficient. For a presenter who moves across the frame, a product demonstration with close details, or a layout with edge-positioned text, inspect the portrait preview carefully. If the crop is wrong, redesign the landscape framing around the centre or use a route with separate portrait composition. YouTube's [live streaming instructions for desktop] (https://support.google.com/youtube/answer/2474026?co=GENIE.Platform%3DDesktop&hl=en-gb%3B) describe its dual formats and stream setup; check the current Help page and your account's available controls before relying on the option.
TikTok LIVE Studio Dual layout
TikTok LIVE Studio's Dual layout starts from the portrait layout. Its help instructions say to right-click a scene, choose Switch layout and select Dual layout. In this mode, sources from portrait are synced into landscape, where you can reposition or resize synced sources. That gives you more adjustment than a fixed centre crop, but it is not the same as maintaining two entirely independent scenes.
The practical implication is to design the portrait arrangement first, then inspect the landscape result and adjust it where the controls allow. A source that looks balanced in a tall frame may leave too much empty space in a wide one. Check each camera, text element and visual source at the actual output shape rather than relying on the editor thumbnail alone.
Some widgets do not carry across. TikTok documents that chatbox and ranking widgets are removed when moving a landscape scene into Dual layout because those widgets are unsupported in portrait. If those elements are important to the broadcast, plan a different way to communicate the information or choose another workflow. Do not build an event around a widget before checking whether it remains in both layouts.
This route is particularly relevant when TikTok is a required destination and a synced source set is acceptable. It is less suitable when the portrait and landscape editions need different scene logic, such as a vertical close-up and a wide multi-person panel. TikTok's Dual layout help article explains the feature and its supported elements; review it again before a scheduled session because controls may change.
Restream Studio and its OBS Vertical plugin
Restream Studio lets you assign channels under Portrait or Landscape before going live. One Studio session can produce both orientations, but the channel orientation choices are made before the broadcast and cannot be changed while live. Elements appear in both shapes, though the amount of space available differs, so a logo, lower-third or guest tile may not land as expected in each output.
That makes a preflight layout check essential. Decide which channel receives which orientation, then confirm that captions and other overlays remain visible. If an audience is on a portrait channel, a landscape-optimised title can become cramped; if the landscape image is only a rearrangement of elements, verify that it still looks deliberate rather than merely resized. Restream's Studio instructions set out its orientation assignment process.
For people who build their scenes in OBS, Restream's Vertical plugin adds a vertical scene alongside the main OBS stream. That can provide a distinct portrait framing without abandoning the existing landscape scene. It is a different choice from Studio's shared element handling, and it involves a plugin workflow: install the version for macOS or Windows, create the vertical scene, set channel orientation in Restream before going live, then start OBS.
Check audio and encoding assumptions as well as the picture. The plugin's vertical output uses the primary OBS audio mixer, and its encoding settings inherit from the main OBS settings, although a separate bitrate is available. If you expected an independent audio mix or fully separate encoder configuration, verify those controls before committing. Through this Restream route, YouTube receives separate live events for the two orientations, so audience links and event setup may not behave like one event with an automatically generated second view. Restream's OBS plugin guide documents the current workflow.
Streamlabs Desktop Dual Output
Streamlabs Desktop Dual Output offers separate horizontal and vertical settings, with per-source visibility controls. The arrangement is useful when a source should appear in one orientation but not the other, or when you need to position overlays differently. Connect the destinations, enable Dual Output, configure each orientation tab, arrange sources and preview both. At Go Live, assign destinations to the intended vertical or landscape output.
Separate canvases make it easier to treat each frame as a composition rather than a crop. They also create more opportunities for mismatches: a hidden source may be absent in the wrong version, or a text overlay may be readable on one canvas and too small on the other. Review both outputs with the same care you would give two separate scenes. Streamlabs' guide recommends 1080x1920 at 30 FPS for TikTok; that is its configuration recommendation, not a guarantee of performance for every computer, connection or scene.
The guide states that multiple destinations within each orientation require Streamlabs Ultra. That is a specific tier condition, so check Streamlabs' current support page and your account before planning a multi-destination setup. This article does not treat a paid tier as necessary for everyone: a single destination or a different supported workflow may be enough. Streamlabs' Dual Output guide is the place to confirm its steps and current limits.
Check destination support and live-setting limits
Make a destination map before spending time on layouts. For each platform or channel, note whether it needs portrait, landscape or both, which method supports that route, and whether the output is a separate live event or a format derived inside the destination. A workflow that works for YouTube does not establish that TikTok or another channel receives the same outputs. Check current account eligibility too, particularly when a feature is rolling out or depends on a software integration.
Next, record which decisions become fixed at Go Live. YouTube says its vertical output cannot be removed after the stream starts. Restream Studio requires channel orientation to be assigned before the broadcast and does not permit changing it live. Other methods have their own controls and constraints; do not assume they match these examples or that every layout can be edited on-air. Treat any uncertain control as something to verify in the current official guide, not as a fallback plan.
Then build the two compositions and inspect them at their intended sizes. Check faces and hands at the edges, text legibility, logos, captions, background detail and any element that communicates a time, name or instruction. For a devotional channel, a lyric line that fits in landscape may need different line breaks in portrait. For local news, a ticker can consume too much of a vertical frame. For a small business, a product close-up may need its own portrait camera crop. These are layout problems, not simply resolution problems.
Audio deserves a separate check. Listen to each route and confirm that speech or music is present, balanced and not unintentionally doubled. In the OBS plugin route, the vertical output uses the primary mixer, so changes to the shared mix affect both. For other routes, confirm their behaviour from the relevant documentation and an actual preview rather than expecting independent controls by default.
Finally, rehearse the exact routing you plan to use. Confirm the right destination receives the right orientation, the correct scene is visible, and the stream key or channel assignment matches. Keep a fallback plan that is realistic: if a vertical output is not eligible or a plugin fails, can you proceed with only the landscape destination, postpone, or switch to a simpler single-format broadcast? A guide to keeping a 24/7 YouTube stream running in India addresses continuity problems, but dual-format composition adds its own checks; a stable connection cannot fix a badly cropped frame.
For a repeating channel, remember that the content itself may have been designed for one format. A pre-recorded landscape loop does not become a considered portrait programme just because a platform crops it. Before making the loop part of an always-on schedule, check sample sections with titles, credits and any important visual moment visible. The guide to streaming old gaming videos as a YouTube live channel is relevant when adapting an existing library: an existing file still needs framing that suits the output viewers receive.
The simplest workable route is the one whose constraints you can test and live with. Choose Auto when a centre crop is genuinely acceptable; choose a synced layout when shared sources with some repositioning suffice; use separate scenes when portrait and landscape need distinct framing. Do not select on the basis of a feature label alone. Confirm the destination, preview each composition, and check the current official documentation before the event.

FAQ
Can I send portrait and landscape video to every platform at once?
No single method guarantees both formats to every destination. Support depends on the platform, account eligibility and the software route, so map destinations first and verify current documentation before scheduling.
Does YouTube make a separate portrait scene automatically?
YouTube's Auto dual-stream route creates portrait by centre-cropping the horizontal feed. If important content sits outside that crop, reframe the landscape scene or use an encoder workflow that supports a separately composed vertical output, where available to your account.
Can I change the layouts after going live?
Do not assume so. YouTube says the vertical stream cannot be removed after a stream starts, and Restream Studio says orientation cannot be changed midstream; other tools have their own controls, which you should check before broadcast.
Which route should I choose for a 24/7 channel?
Use the route that supports your destinations and preserves the important parts of your composition. A centre crop can suit a centred, simple scene; separate canvases are better when the portrait version needs different framing, but require more preparation and testing.
