Set OBS’s Output (Scaled) Resolution to 1920×1080 to send a 1080p-sized feed to YouTube. For a straightforward 16:9 scene, set Base (Canvas) Resolution to 1920×1080 as well, then fit each clip to the canvas and check how its shape appears.
The output setting does not turn every source into native 1080p or make differently shaped clips fill the frame without a trade-off. It also does not guarantee that YouTube will deliver 1080p to every viewer: encoding, connection, and YouTube’s viewer-side transcodes all matter.
Set the stream output to 1920×1080
In OBS, open Settings → Video and set Output (Scaled) Resolution to 1920×1080. This is the size OBS scales the composed scene to for the stream. The OBS overview guide distinguishes this output from the canvas used to arrange sources.
This lets you combine clips with different pixel dimensions in one scene. A 720p clip can be scaled up into the 1080p output, but the additional pixels do not restore detail that is absent from the source. A 1080p clip may retain more detail, while a smaller or heavily compressed clip can look softer beside it. Keep the distinction clear: the stream frame can be 1920×1080 even when an individual file is not.
Choose a frame rate that suits the material and the computer doing the encoding. If most clips are 30 fps, 30 fps is a reasonable starting point; it is not a requirement. YouTube’s encoder guidance covers frame rates up to 60 fps, and OBS notes that higher frame rates demand more resources. Test the actual scene rather than choosing 60 fps solely because it is available.
Match the base canvas to a 16:9 scene
For a simple 16:9 layout, set Base (Canvas) Resolution to 1920×1080 in the same Video settings panel. Think of the base canvas as the workspace where you position and size sources, and the scaled output as the final frame sent to YouTube. Matching them keeps this setup easy to reason about because the workspace and target frame have the same dimensions.
If your existing scene uses a different canvas, changing it can move or resize sources relative to the new frame. Check each scene after making the change; OBS notes that sources may need realignment or resizing when the base canvas changes. This matters if you have overlays, a logo, captions, or several media sources arranged around a background.
A different canvas can be appropriate when a scene has a specific layout or production requirement. For a straightforward landscape loop, though, matching both settings to 1920×1080 gives you a clear reference frame. The canvas choice still does not change the shape or intrinsic resolution of the video files themselves.
If your longer-term concern is keeping a broadcast running after your personal computer is switched off, resolution settings are only one part of that decision. The trade-offs in running a YouTube livestream without a PC are separate from the visual setup described here.
Add your clips as media sources
Add a local file to OBS as a Media Source. For a sequence of files, you can instead use the VLC Video source and arrange the clips as a playlist. OBS documents both choices in its Media Sources guide, including their loop controls and the VLC dependency for playlist playback.
A source’s pixel dimensions need not match the output dimensions. Place the source in the scene, select it, and use Transform → Fit to Screen (or Ctrl+F) to scale it into the canvas while preserving its proportions. Then inspect the result. Fit is a useful starting point for 16:9, 4:3, vertical, and other differently shaped material, but it does not make each shape occupy the same area of the frame.
Check how files enter and leave the scene as well as how they look while playing. A playlist can contain a mix of clips with different dimensions, aspect ratios, or framing. Do not assume that one transform choice produces the desired composition for every file. If the playlist requires different framing for particular clips, test those transitions in the scene you intend to broadcast.
For a source that will run from a cloud-storage workflow instead of a local OBS playlist, the constraints differ; see how cloud storage can feed YouTube Live. For the OBS route in this article, keep the files available to the computer running OBS and validate them there before going live.
Fit or stretch, with the shape trade-off in view
With Fit to Screen, OBS scales a clip to fit within the canvas while retaining its aspect ratio. If the clip is narrower or taller than the 16:9 frame, unused areas can remain around it. A 4:3 clip can leave space at the sides; a vertical clip can leave substantial space on both sides. That is not a resolution failure: it is the consequence of preserving the source’s shape inside a differently shaped frame.
Stretch to Screen fills the canvas, but can distort the image because it changes the source proportions. A person, building, or circular logo may look wider or narrower than intended. Stretching is therefore a composition choice, not a way to preserve proportions while removing all empty space.
| Transform | What it does | What to check |
|---|---|---|
| Fit to Screen | Scales the clip into the canvas while keeping its proportions | Empty bars or space can remain when the source shape differs from 16:9 |
| Stretch to Screen | Fills the canvas by changing the displayed proportions | Objects and people can appear distorted |
Cropping is another possible composition choice where you need edge-to-edge coverage but cannot accept stretching. It cuts off part of the source, so check that important subjects, text, or devotional imagery are not lost at the edges. No single treatment is right for every clip: fit preserves the full image, stretching fills the frame at the cost of shape, and cropping fills by discarding part of the image.
For a channel built from bhajans, ambient scenes, or study visuals, decide which matters more for each source: showing the whole frame or filling the screen. You can keep a 16:9 background behind a fitted vertical clip, for example, but that background is a design layer, not a property of the source. Preview the complete composition so empty space looks intentional rather than like a missing signal.
Choose a single-file loop or a playlist
If the channel repeats one video, add a Media Source and enable Loop in its source properties. This is the simple route when the same file is intended to repeat. OBS’s Media Source documentation describes this control; test the end and restart of the file so you can see whether the transition suits the channel.
If you want several videos to play in sequence, add a VLC Video source, arrange the files in the playlist, and enable Loop Playlist. The VLC source requires VLC to be installed, so it will not appear as an option if that dependency is missing. A playlist gives you variety without changing the stream output target, but it adds a dependency and more transitions to validate.
| Playback choice | Suitable for | Dependency | Repeat control |
|---|---|---|---|
| Media Source | One local file | OBS Media Source | Loop |
| VLC Video | Several files in sequence | VLC installed | Loop Playlist |
These controls repeat playback; they do not establish that a stream will remain live indefinitely. Check that every playlist entry opens, plays with sound if expected, and hands off correctly to the next entry. If one file has different dimensions or aspect ratio from the rest, check its framing separately in the preview. The same output setting can accommodate the sources, but it cannot standardise their composition for you.
Preview the scene for space and distortion
Before streaming, use the OBS preview to check representative clips from the beginning, middle, and end of a file or playlist. Include the least common shapes in the set, not just the 16:9 clips. Look for empty bars or space, stretched faces or objects, cropped text, overlays covering important content, and any source that appears off-centre after a transition.
Compare the source with the composed scene. If a 720p file looks soft in a 1080p canvas, that is different from black space caused by fitting a vertical clip. One points to source detail; the other is a framing choice. Raising the output setting cannot supply missing detail, and stretching a source to fill the screen does not fix its resolution.
Also check audio at a representative level and across clip transitions. A loop may have a pause, abrupt cut, or volume change at the seam even when the picture is correctly framed. YouTube advises testing with movement and audio similar to the planned stream. For practical checks around pauses and playback interruptions, how to fix a black screen in streaming software is a useful companion, but do not treat a clean preview as proof that a long broadcast will never fail.
Connect to YouTube and check the incoming feed
When the scene is ready, configure OBS to connect to the intended YouTube broadcast using its stream URL and key. YouTube’s live encoder guidance lists settings for the incoming feed, including bitrate, codec, keyframe interval, and audio. Keep the stream key private, and check that the destination is the correct channel and scheduled or active stream before starting the test.
For H.264, YouTube lists 5 Mbps minimum and 14 Mbps recommended at 1080p30, and 6 Mbps minimum and 17 Mbps recommended at 1080p60. These figures are YouTube’s encoder guidance, not a guarantee that a particular connection or computer can sustain a broadcast. The same YouTube live encoder settings recommend CBR and a 2-second keyframe interval, with no more than 4 seconds between keyframes. Follow the current official guidance for the codec and frame rate you actually use, rather than copying settings for a different format.
Run a private or otherwise suitable test before relying on the setup. Check OBS’s output and YouTube’s stream-health messages while the video is moving and audio is playing. A still image may hide encoding or network issues that appear once motion resumes. Testing helps you find problems; it does not promise continuous operation.
The encoder’s 1080p setting describes the feed you send, not the exact rendition every viewer will see. YouTube transcodes live streams into multiple formats so viewers on different devices and connections can watch. A viewer may receive a different quality according to playback conditions. If you are planning a long-running channel, separate the question of the stream’s output resolution from the question of how it is operated; a nonstop church stream: cloud service or VPS covers that operational choice.
For a local OBS setup, your own computer and connection remain part of the path to YouTube. If keeping that computer on is the specific source of overnight interruptions, StreamNeo removes that particular need by letting you upload a video and provide your YouTube stream key so it can run as a 24/7 broadcast while your computer is off. It is YouTube-only; it does not change the source’s detail, aspect ratio, or YouTube’s viewer-side playback selection.

FAQ
Does setting OBS to 1920×1080 make every clip 1080p?
No. It sets the size of the output frame, while a smaller source is scaled up and may look softer than native 1080p footage. Check the source files as well as the OBS output setting when picture detail matters.
Why do bars remain after I fit a clip?
Fit preserves the clip’s proportions and scales it inside the canvas. When its shape differs from 16:9, unused space can remain; filling that space means accepting a different composition through cropping or possible distortion through stretching.
Will viewers always see the stream in 1080p?
No. A 1080p encoder output does not guarantee a 1080p rendition for every viewer. YouTube transcodes live streams, and a viewer’s device and connection affect the quality available or selected.
Which OBS option loops several clips?
Use a VLC Video source for a playlist, arrange the files, and enable Loop Playlist; VLC must be installed for this source. For one file, use a Media Source and enable Loop. Neither setting alone guarantees an uninterrupted 24/7 broadcast.
