A portrait clip can play in a landscape YouTube live loop, but you need to decide what the landscape frame should show: a cropped close view, or the full portrait image with space around it. Start with a 16:9 landscape canvas, then scale and reposition the clip for the shot; do not stretch it to fill the frame.
A crop that works for one shot may cut off a face, caption or moving subject later in the loop. Preview the whole clip before streaming. If you also need a portrait broadcast, that is a separate output and layout workflow, not something a landscape loop creates by itself.
Set the goal: portrait source, landscape output
Your source and output have different shapes. A portrait video is taller and narrower than a 16:9 landscape frame, so fitting one into the other requires a composition choice. You can enlarge the portrait image until it fills the landscape canvas, which crops away parts of the source, or preserve the complete image and use the unused space for a background or other scene content.
For example, a devotional clip may show a singer and a caption near the lower edge. Filling the frame can make the singer larger, but may remove the caption or details at the top and bottom. Preserving the full portrait view keeps those details, but leaves space at the sides that you need to compose deliberately.
Think about what the viewer needs to see before choosing a treatment. For a close-up with a centred face, a crop may be clear and simple. For a dance, demonstration or shot with text near the edges, showing the whole portrait frame may be more useful. The right choice depends on the footage; there is no single crop that suits every portrait shot.
This is a framing decision, not a reason to change the proportions of the image. Keep the source's shape intact, then choose which parts fit into the landscape composition. If your practical question is how to arrange a full video for a live broadcast, the guide to looping a video on YouTube Live with VLC covers the playback side; this article focuses on the frame itself.
Create a landscape 16:9 canvas
Set the output canvas to landscape before adjusting the portrait clip. OBS gives 1920x1080 and 1280x720 as examples of 16:9 output sizes in its aspect-ratio guide. These are examples, not mandatory resolutions. Choose the canvas and frame rate that suit your actual streaming setup and source material.
The canvas is the frame the live stream sends out. The clip is an item placed inside it. If you begin by resizing the canvas to match the portrait source, your output will be portrait rather than landscape. If you enlarge the source without setting a landscape canvas, you may also end up evaluating the wrong composition for the final broadcast.
In your editing or scene software, create a landscape project or scene, then add the portrait clip. The labels and controls differ between applications, so look for the canvas or output dimensions and the source's scale and position controls rather than relying on a particular menu path. Confirm the preview itself is landscape before you begin cropping.
You can use one prepared landscape clip in a playback workflow or compose the source live in a scene. Either way, check that the landscape framing is part of the content being sent to YouTube. A correctly shaped canvas does not automatically make the portrait source fill it well. If you are still choosing a playback approach, adding a video playlist to OBS is a separate setup question from deciding how each item is framed.
Crop and reposition for the shot
To make a portrait image fill a landscape canvas, scale it up while preserving its proportions. Continue until the canvas is covered, then move the enlarged image to place the important part of the scene inside the visible frame. The parts beyond the canvas edges are cropped from the output; they are not stretched or displayed elsewhere.
A centred crop is a useful first preview when the main subject is centred. It is only a starting point. If the subject sits to one side, reposition the clip. If the important content is too high or low, move it vertically as well. Your aim is not to keep the clip's centre aligned with the canvas centre; it is to keep the information that matters in view.
Check the crop against the actual shot rather than a still frame at the beginning. A person may walk across the frame, a camera may pan, or a caption may appear near an edge later on. A fixed position that looks right for the opening can fail after a cut or movement. If the subject cannot stay in frame under one fixed crop, use a different composition, a full-frame treatment or a separate crop for that part of the video.
Keep the crop purposeful. A tight frame can make the main subject easier to see on a landscape screen, but it can also remove context, hands, instruments, signage or subtitles. A wider crop retains more surroundings but may leave the subject small. Watch the clip at the size at which you expect viewers to see it, not only in a large editing preview where small details appear easier to read.
If the crop needs adjustment at different points, decide whether your editor can animate position or whether it is simpler to split the video into sections with different framing. Do not assume the live platform will correct the composition for you. The framing should be visible and checked in the prepared landscape output before you rely on it in a long-running loop.
Avoid stretching the portrait image
Stretching means changing the image's width and height by different amounts to force the source to match the landscape canvas. A face becomes wider or narrower, circles become ovals, and familiar objects look distorted. The frame may be filled, but it no longer represents the source's proportions accurately.
Scale proportionally instead. As you enlarge or reduce the source, its width and height should change together. Then choose between cropping the excess and preserving the entire image with a designed background. OBS cautions against stretching mismatched content in its aspect-ratio guide; it also describes filling unused canvas space with other content such as images, overlays or cameras.
Those are distinct composition choices. Crop-to-fill gives the portrait image more of the landscape canvas, at the cost of discarding parts of the source. A background treatment keeps the full source, at the cost of using less of the canvas for the main image. You might place the portrait clip over a colour, a still image or other relevant scene content. A blurred enlargement of the same clip is another editorial approach, but it is a design choice, not a requirement.
| Composition | What stays visible | Main trade-off |
|---|---|---|
| Crop to fill | A selected part of the portrait clip | The landscape frame fills, but edges of the source are lost |
| Preserve full frame | The complete portrait image | Nothing is cropped, but space remains around the image to design |
| Stretch | The whole image forced across the canvas | The frame fills, but the image proportions are distorted |
Avoid using stretch as a quick fix just because it removes blank space. If the full portrait image is important, make the surrounding space look intentional. If filling the landscape frame is more important, crop and reposition while keeping the image's proportions intact.
Preview captions, faces and motion
A preview should cover the whole loop, including each cut, transition and moment when the subject moves. Scrub through it or play it from beginning to end, checking the intended crop throughout. A single still preview cannot tell you whether a moving person will leave the visible area or whether an on-screen caption appears outside the crop later.
Make a short checklist for the material that matters in your clip. Check faces and eyes, hands or instruments if they carry the action, text and subtitles, logos that must remain visible, and any objects the viewer needs to understand the scene. Keep enough space around moving subjects that they do not look pressed against the edge. For text, confirm that the entire line remains inside the visible frame rather than assuming it will be readable because it appears in the source preview.
Inspect every point where the footage changes. Different clips in one loop may have different subject positions, even when all were recorded in portrait. One crop can suit a centred singer and fail on a second clip where the person is off to the left. If your playlist contains several sources, check each one; do not carry one position setting across the whole playlist without confirming the result.
Also review the background if you choose to preserve the full portrait frame. Check that it does not compete with captions or make the main video hard to distinguish. A duplicate or blurred background can occupy side space, but strong detail behind the subject may be distracting. A plain fill can be more readable than a decorative treatment, particularly when text is part of the clip.
Finally, view the actual landscape output as a viewer would receive it. Confirm that the preview is not hiding a clipped edge, a caption or a subject near the boundary. If the composition is hard to read at normal viewing size, adjust the crop or switch to a full-frame treatment before the loop goes live.
Keep the recorded loop separate from dual-output production
A prerecorded portrait clip placed in a landscape scene is one output composition: the landscape scene determines what viewers receive. It does not generate a separate portrait broadcast. If you need to serve viewers in both horizontal and vertical formats at the same time, you need a production workflow that prepares and sends each format appropriately.
YouTube Help describes horizontal live streams as 16:9 and vertical live streams as 9:16. For its Live Control Room workflow, YouTube offers a vertical layout editor with choices including Center crop, Fit to phone width and Stacked, as well as zoom and position adjustments. YouTube also describes the vertical stream there as a centre crop of the horizontal stream by default. These are controls for configuring a live layout in that workflow, not general instructions for cropping every prerecorded clip. See YouTube's live streaming guidance for the current details.
An encoder-based dual-stream setup is a different path. YouTube's documented workflow uses RTMP(S), an encoder selection in the vertical preview and a second stream key for the vertical stream. The horizontal and vertical keys need to receive their matching formats. YouTube says the vertical format cannot be added after the stream has started, so plan and check both outputs before going live if you choose this setup.
For a single landscape loop, you do not need to build a second portrait output merely because the source video was recorded vertically. Focus on the landscape scene and its crop. For a simultaneous portrait and landscape broadcast, plan separate layouts and test that each output shows the intended composition. A 24/7 stream workflow that resumes after a reboot addresses continuity; it does not replace the framing work required for two aspect ratios.
Prepare a loop that can keep running
Once the crop is right, inspect the complete sequence for continuity. A repeated landscape loop can make a framing mistake just as repeatable as a good composition. Watch the point where the end returns to the beginning, as well as transitions between clips. If the subject jumps position or a caption appears in a different place, adjust the source or composition before setting it to repeat.
Check the prepared file or scene in the playback path you will actually use. A preview inside an editor and the output sent by a streaming tool are not always the same view. Confirm that the selected landscape canvas, scaling and position survive the hand-off into your stream setup. If you are comparing playback methods, the article on running a 24/7 FFmpeg stream from an older laptop covers an operating trade-off, not a substitute for checking the picture.
For an always-on channel, also decide where the loop lives and who will notice if it stops. Running playback on your own computer means that computer and its connection have to remain available. If that is the specific interruption you are trying to remove, StreamNeo can take an uploaded video and stream it to YouTube without keeping your computer on; you still need to prepare and check the landscape framing first.
Keep a clean copy of the original portrait source. If a future scene needs the full frame or a different subject position, the original gives you room to prepare another landscape version without trying to reverse a crop. Save the chosen output dimensions and any important framing notes alongside the project, especially when a playlist contains clips that need different treatment.

FAQ
Should I crop every portrait clip to fill the landscape frame?
No. Crop only when the part that remains visible communicates what the clip needs to show. If a caption, gesture or moving subject would be cut off, preserve the full portrait frame and compose the side space instead.
Can I stretch a portrait video to fit 16:9?
You can force the image across the canvas, but that changes its proportions and distorts the picture. Scale it proportionally, then choose a crop or a background treatment.
Does a landscape loop also create a portrait live stream?
No. A landscape scene sends a landscape composition. A simultaneous vertical output needs its own suitable layout and a streaming workflow configured for that format.
When should I use a background rather than a crop?
Use a background when the whole portrait frame contains important detail or when one fixed crop cannot keep the subject in view. Crop to fill when the selected part of the image works on its own and you are comfortable leaving the rest outside the landscape frame.
