If your devotional video is portrait, the cleanest result comes from composing for a vertical output and keeping the clip’s original proportions. If you also want a conventional horizontal viewing option, YouTube documents a Live Control Room flow for vertical layouts; prepare and inspect that layout before starting rather than assuming every viewer or device will receive a particular version.
In OBS, the important choice is the shape of the scene, not a trick that forces a portrait clip to fill any frame. A landscape canvas can show the full portrait image with intentional side space, but stretching it will distort faces, artwork and text. This guide covers both approaches and how to check the devotional focal points before you go live.
Choose one output or YouTube’s vertical-layout flow
Start by deciding what you want to produce. A single vertical output makes sense when the source itself is portrait and the composition is meant to be read on a phone: for example, a darshan clip framed around the murti, or a bhajan video with lyrics placed below the singer. Build the OBS scene around that shape, then confirm in YouTube’s preview that the output is accepted and framed as intended. Exact menus can vary by software version, so treat the settings below as composition guidance rather than click-by-click instructions for every OBS build.
A horizontal output remains useful if your channel’s programme is designed for a television or desktop frame, or if it includes material arranged across the width. You can put the portrait clip inside a 16:9 scene without changing its proportions. The remaining space becomes part of the design: plain colour, a restrained blurred background, or other relevant scene content can make it look deliberate instead of like a failed fit.
If you want horizontal and vertical audiences at the same time, YouTube’s Live Control Room documents vertical-layout options and an encoder-based setup. The options are not interchangeable with simply stretching one portrait source to landscape. The documentation describes layout choices including center crop, fit to phone width and stacked; for an external encoder, YouTube’s flow uses RTMP(S) and a second stream key for the vertical output. The format sent to each key needs to match that stream.
| Approach | Useful when | Main trade-off |
|---|---|---|
| Single vertical output | The devotional source is portrait and the intended composition is phone-shaped | Horizontal-screen presentation may not be the composition you want; check the actual YouTube preview. |
| Horizontal scene with portrait clip fitted | You want a conventional wide scene and need to preserve the whole portrait image | Unused side space remains unless you design the rest of the scene around it. |
| Live Control Room vertical layout | YouTube’s documented layout options suit your source and channel workflow | A crop can remove side content, while other arrangements need deliberate framing and preview. |
| Separate encoder outputs | You need separate landscape and vertical compositions and can configure each stream key correctly | More setup to check: output formats, keys and both previews must agree. |
YouTube describes vertical live streams as a full-screen mobile viewing experience and says people browsing Shorts may find them. That is a product description, not a promise of discovery or reach. Feature availability and presentation can change, so check the current YouTube vertical live streaming help page and the options visible in your own Live Control Room. YouTube also lists some feature differences between orientations; do not assume every horizontal feature is available in a vertical feed.
Set the OBS canvas around the portrait clip
For a single vertical output, set the OBS base canvas and output resolution to a portrait aspect ratio accepted by your chosen YouTube encoder setup. In OBS, the base canvas is the workspace on which sources are arranged; output resolution determines the encoded frame sent out. Keeping them aligned avoids composing a portrait scene in one shape and then unexpectedly scaling it into another. You can find the controls in OBS’s video settings, though the exact labels may differ by release.
A 9:16 shape is a common portrait proportion, but the source and the platform’s accepted stream settings should guide the final choice. A clip might have borders baked into the file or use a slightly different crop. Check its properties and compare the frame in OBS’s preview before settling on the canvas. You do not need to buy a capture card or other physical product to solve this layout problem; this is a matter of scene composition and output configuration.
For a horizontal output, keep the landscape canvas and add the portrait clip as a source. Scale it until the full width and height of the source fit inside the canvas. It will occupy a narrow central area, leaving space to the left and right. That is not a fault in OBS: it is the geometric result of fitting a tall rectangle inside a wide one without cropping or distortion.
If you fill that side space, keep the background subordinate to the main devotional image. A static colour, a softened duplicate of the clip, or a restrained border can work, depending on the material. Avoid adding decorative elements that compete with scripture or the deity image. For more guidance on building a composed scene, see how to customise a stream with overlays. An overlay should support the picture rather than cover the very content viewers came to see.
YouTube’s encoder documentation is useful if the requirement is genuinely to send separate orientations rather than to place a portrait clip inside one landscape scene. It explains the RTMP(S) flow and the use of a second vertical stream key. Read the current YouTube encoder setup guidance alongside Live Control Room: the key detail is that each output must go to its corresponding key in the matching format.
Preserve proportions instead of stretching
A portrait source has a fixed relationship between width and height. If you drag its left and right edges independently until it fills a landscape canvas, you change that relationship and warp the image. Faces appear wider, circular motifs become oval, and lettering can become difficult to read. OBS’s aspect ratio guide advises against stretching mismatched content for precisely this reason.
Use a fit operation that scales the source uniformly, or adjust its size while keeping the aspect ratio locked. In a landscape frame, fitting the whole portrait clip leaves side space. In a portrait frame, a landscape source that fills the screen must lose material at the sides or top and bottom, depending on the crop. Neither is a software defect; each is a framing choice.
The distinction matters when a source is a recording of a temple or a singer with important material near the edge. If you choose a crop, inspect which parts disappear. If you choose fit, decide how the unfilled area should look. If neither compromise suits the source, prepare a dedicated portrait edit or scene instead of forcing a mismatched frame.
This is also a useful point to check that OBS is not scaling the source twice through nested scenes or a later output conversion. Select the source, look at its transform and the preview, and confirm that the picture still looks proportionate. For a longer-running channel, changes to the scene are best tested before the stream is scheduled; a practical OBS audio-level guide for an Indian home PC covers a different part of the setup but reinforces the same habit of checking the actual output rather than relying on a setting name.
Keep devotional focal points and text in frame
A fitting method can be technically correct and still produce an awkward devotional composition. Decide what viewers should see first: the face of the singer, the deity image, the scripture line, or perhaps a lamp and altar. Keep that focal point away from the edges if a crop may be used, and inspect the result at the size and orientation where viewers are likely to watch.
For embedded lyrics or prayer text, check the whole line at phone scale. Text that is legible on a laptop preview can become too small on a phone, and text near a crop boundary can be cut off. If the source already includes captions, do not add a second line over them without checking for overlap. When you place new text in OBS, leave a margin from the frame edges and keep it clear of faces and central religious imagery.
YouTube’s documented vertical layout editor allows adjustment of zoom and position. That gives you room to centre a focal point when the source and chosen layout permit it, but it does not make every wide composition safe to crop. A group of musicians spread across a stage, for instance, may not fit naturally in a narrow view. You may need a separate close-up, a designed stacked layout, or the full frame with unused space rather than a tight crop.
For a wide source adapted to a phone-oriented layout, check the whole visual hierarchy, not only the centre pixel. A small shift can keep a face in frame while dropping a prayer line, a temple detail or a second performer. In a devotional context, restrained framing is often clearer than filling every available area with labels and decoration. If the channel uses a recurring clock or other information, keep it secondary; a guide to adding an on-screen clock to an FFmpeg stream offers a related example of placing persistent information in a scene without making it the subject.
Preview the composition before going live
Prepare the stream in YouTube Studio or Live Control Room, then inspect the vertical preview where it is available. Do this after choosing a crop, fit or stacked arrangement, not before. Look at the preview from the beginning and through a representative part of the video: an image can change position, lyrics can appear later, and an opening title can use more frame area than the main scene.
YouTube says a vertical format cannot be added after the stream has started. The layout should therefore be set up and inspected in advance. The documentation notes that you can adjust a layout through the canvas while live, but do not confuse that with being able to add the vertical format once a broadcast is under way. If you are using the encoder path, verify the second key and its corresponding output before starting as well.
A useful preflight is to check three separate views: the OBS preview, YouTube’s available preview, and the actual playback view on a phone if you can test privately or before the public start. Confirm the image is not stretched, no essential text is clipped, audio is present, and the stream is connected as expected. If you make a correction, inspect the preview again; one adjustment to zoom or position can affect more than one visual element.
If your channel loops a prerecorded clip, review what appears at the loop boundary too. Make sure the final frame and restart do not create an unintended blank or abrupt composition change. A separate policy question is whether repeated material is appropriate for your channel; this article explains how YouTube treats repeated plays on a live channel. Check YouTube’s current rules and your channel’s circumstances rather than treating a layout choice as an answer to content-policy questions.
Use YouTube’s documented vertical-layout options where they fit
Live Control Room’s documented options address different source shapes and editorial needs. Center crop is the most direct way to turn a wide source into a narrow view, but it discards the sides. It can work for a centred singer or altar; it is a poor fit for a wide group scene where performers or text sit near the edges.
Fit to phone width keeps the wide source’s width visible in the phone-oriented layout. Depending on the source and canvas, it can leave empty space above and below. Stacked places separate content areas one above another, which can preserve more than a centre crop but makes each element smaller. YouTube allows the operator to adjust zoom and position in its vertical layout editor, so use the preview to decide whether a given arrangement is readable rather than assuming its name tells the whole story.
The encoder-based route is for a more deliberate two-output workflow. YouTube’s instructions describe selecting the encoder option in the vertical preview, using RTMP(S), and choosing a second stream key for the vertical version. Send the matching format to each key. A dedicated vertical OBS scene gives you more control over the portrait composition than an automatic centre crop, but it also means you have another output configuration to validate.
| Layout choice | What it does in practice | Check before using it |
|---|---|---|
| Center crop | Fills the vertical composition by retaining a central portion of a wider source | Are the deity, singer and any text all within the retained area? |
| Fit to phone width | Preserves the wide source’s width in the vertical viewing layout | Does the remaining space look intentional, and is the picture large enough? |
| Stacked | Places content areas in a vertical arrangement | Can viewers still read each element, and does the order make sense? |
| Separate vertical encoder output | Sends a purpose-built portrait scene through the documented encoder flow | Is the second key selected, and does each key receive its matching format? |
The right choice depends on the clip, not on an assumption that one layout suits every devotional stream. If the vertical version needs a distinct crop, titles or focal-point placement, create and test that composition deliberately. If a simple crop removes something essential, choose another layout or keep to a single output that preserves the full image. YouTube’s feature description also notes that horizontal and vertical feeds differ in some capabilities; review its current comparison in the vertical live streaming documentation before deciding what matters to your channel.
Check playback, connection and channel access
After the layout is right, check that the broadcast itself is behaving as expected. In OBS, watch the connection and dropped-frame indicators, and in YouTube Studio check the stream health messages and preview. A stable-looking preview does not prove that every viewer’s device will display the same layout or quality. Use the playback view available to you, and ask a trusted viewer to check a phone or television if you need a second device check.
For the encoder workflow, confirm that the horizontal output is not accidentally being sent to the vertical key, or vice versa. If you are using one output, make sure the selected stream settings and preview correspond to the intended orientation. Keep a record of the scene and stream configuration that worked; that makes the next scheduled broadcast easier to prepare without treating last time’s settings as a guarantee.
YouTube’s general live-stream eligibility guidance says channels need verification and must not have had a live-streaming restriction in the preceding 90 days; it also gives a minimum streamer age of 16. The reviewed official guidance does not describe a separate India-specific OBS canvas procedure. Check YouTube’s current live streaming eligibility page and your Studio account before planning a broadcast, since account-specific access and current platform rules matter more than assumptions about region.
The orientation decision is only one part of running a channel continuously. If your concern is keeping the stream available after a disconnect, investigate the actual cause and test recovery separately; a troubleshooting guide for a radio stream that appears offline after reconnecting is relevant to that operational problem, but it will not determine whether a portrait frame is composed correctly.

FAQ
How do I make a vertical video fit in OBS?
Use a portrait canvas and output for a single vertical composition, or fit the portrait source proportionally inside a landscape canvas and design the side space. Do not stretch the source to fill a frame with a different aspect ratio. Preview the result in OBS and YouTube before going live.
Can YouTube show vertical and horizontal layouts at the same time?
YouTube documents a Live Control Room vertical-layout flow and an encoder-based setup using RTMP(S) and a second stream key for vertical output. The encoder flow requires the matching format to go to the corresponding key, and you should verify the preview before starting. Do not assume a particular layout will be delivered to every viewer or device.
Which YouTube vertical layout should I use for a bhajan video?
Use center crop only if the important subject and text remain in the crop. Fit to phone width can retain a wider source, while stacked can organise separate elements vertically, but each has its own space and readability trade-offs. Check the actual preview with the full composition, including lyrics and opening titles.
Can I add the vertical version after I have started streaming?
YouTube’s documentation says the vertical format cannot be added once the stream has started, so set it up and inspect it beforehand. It describes adjustments through the canvas while live, but that is different from adding the format after starting. Check the current Live Control Room instructions for the flow available to your channel.
