If YouTube shows a stream health warning after your 24/7 stream changes resolution, first read the full message in Live Control Room, then compare the encoder’s actual output width and height with the resolution selected for ingestion. YouTube requires those dimensions to match when it reports an incorrect video size; changing the stream key is not the first fix.
For a devotional or bhajan channel, the troubleshooting is the same as for any other YouTube Live stream. Keep the outgoing dimensions consistent during a live session where possible, test changes in advance, and do not assume a resolution change can be made without interruption: YouTube does not document a guaranteed seamless procedure for that situation.
Read the warning before changing settings
Open YouTube Studio and the stream’s Live Control Room. Find the Health Indicator and read the complete message, including when it appeared. The wording and timestamp help distinguish a resolution mismatch from a bitrate, connection, or other encoder issue. YouTube explains how to interpret stream health messages in Live Control Room.
An “incorrect video size (resolution)” warning points you towards the sent video dimensions. A warning about an unsupported or non-optimal resolution is also a reason to compare what the encoder is sending with the ingestion configuration. Do not respond to every warning by lowering resolution or restarting OBS; first address the category YouTube actually reports.
The indicator can show a continuing issue again if it has not been fixed. YouTube describes red errors as critical and yellow errors as moderate problems that may affect quality. Record the message and its time before adjusting anything, so you can tell whether a later warning is new or the same issue recurring.
For a long-running devotional stream, make this a repeatable check rather than relying on a quick glance at the viewer page. A static temple image may make the picture appear normal even while a health message is present. Check the Live Control Room’s encoder preview and health status, and note whether the warning began when a playlist, scene, source, or output setting changed.
Check that you can manage the channel
Before touching the encoder, confirm that the Google account you are using can manage the intended YouTube channel and access YouTube Studio’s live tools. If you manage a temple, trust, music label, or community channel for someone else, make sure you are signed into the correct account and have the channel permissions needed to create or manage a live stream.
Channel access is separate from the resolution mismatch itself. If you cannot open the relevant Live Control Room or stream settings, ask the channel owner or administrator to confirm your access rather than trying random account or encoder changes. Do not paste a stream key into a chat, public document, or message to someone who does not need it; it is a credential used by the encoder to send the feed.
Confirm that you are working on the channel viewers expect to see. This matters when a person’s Google account has access to multiple channels, such as a personal channel and a devotional organisation’s channel. A correctly configured OBS instance can still send to the wrong destination if the selected YouTube stream belongs to another channel.
Select the stream in Live Control Room
In YouTube Studio, create a live stream or select the existing stream you intend to use, then open its Live Control Room settings. Check the Ingestion Settings page for the selected resolution and whether resolution and frame rate are set to automatic detection or manually configured. YouTube’s default recommendation is automatic detection; manual selection is available through a custom stream key.
The encoder supplies the video resolution, frame rate, and bitrate. YouTube detects those incoming settings and transcodes the stream into multiple output formats for viewers. That does not mean YouTube will correct an inconsistency between the resolution selected for ingestion and the dimensions your encoder sends. For the incorrect video size warning, its requirement is that the sent video has the width and height of the selected resolution.
If YouTube has automatic detection enabled, check what OBS is actually outputting, rather than assuming a source’s resolution dictates the final stream dimensions. OBS has its own output settings, which can differ from the size of a video file or scene. If manual resolution is in use, compare the manual selection with OBS’s outgoing canvas and scaled output, not only with a label attached to the source.
The stream can change resolution when the encoder output changes, even if the YouTube stream itself has not been replaced. For example, an operator may alter OBS output scaling while replacing a lower-resolution bhajan recording with a higher-resolution one. The source switch and the encoder output are different things: the warning concerns the dimensions sent to YouTube relative to its ingestion setting.
Copy the stream URL and key carefully
In the selected stream’s settings, locate the stream URL and stream key. Use the URL shown by YouTube and the key associated with that stream. If you reuse a custom key, check its settings too, particularly whether it pins a resolution. Keep the key private. Do not reset it merely because the video resolution changed; the guidance here gives no reason to replace a working key unless there is a key or credential problem.
In OBS, the stream URL identifies YouTube’s ingest destination, while the stream key identifies the feed YouTube should accept. They belong in OBS’s streaming configuration, not in the video source properties or a scene title. If OBS is already connected and the stream key works, focus first on the dimensions and output configuration implicated by the warning.
When you compare settings, write down the chosen ingestion resolution and the actual OBS output width and height. “HD” or “1080” in a filename is not a reliable substitute for checking the numeric dimensions in the configuration. Likewise, a video source may have one resolution while OBS scales it to another before sending it.
For a step-by-step starting point on the YouTube and OBS workflow, see streaming prerecorded videos to YouTube Live with OBS on Windows 11 in India. The details of an existing channel and OBS version can differ, so treat the current Live Control Room values and the OBS output panel as the source of truth for your own setup.
Set up OBS to match YouTube
When YouTube service is available in OBS, open Settings, then Stream, select YouTube - RTMPS or the YouTube service option shown in your OBS version, and connect the account or enter the stream key as prompted. The exact labels can vary between OBS releases. If you connect an account, confirm that it is the same channel for which you selected the stream in Live Control Room.
Then check Settings, Video and Output. The base canvas, output resolution, and any output rescaling affect what OBS sends. Match the outgoing width and height to the resolution selected on YouTube’s Ingestion Settings page. If the warning began after an output change, restore the previously working dimensions or select the intended dimensions consistently on both sides, then test before relying on the change.
Frame rate and bitrate should be considered alongside resolution, but do not change them without a reason. YouTube publishes current encoder settings and bitrate guidance, which vary by codec, resolution, and frame rate. Check that page for current recommendations rather than reusing a number from an old setup guide. The essential resolution fix remains matching the actual sent dimensions to the selected ingestion resolution.
If the stream uses H.264, the H.264 settings guide for YouTube Live may help you understand the related codec and output choices. It is not a substitute for checking the dimensions. A codec setting that is acceptable in general cannot resolve an output-size mismatch by itself.
Use custom service fields only when needed
If OBS does not offer a usable YouTube service option, choose its custom service configuration and enter the stream URL and key into their separate fields. Copy both values from the correct YouTube stream. Do not paste the stream key into the URL field, and do not add extra text or spaces when copying credentials. A custom-service setup is a way to supply the destination and credential directly; it does not change the rule that the outgoing resolution must match the selected ingestion resolution.
If you use a custom stream key to set manual resolution, check its Stream Resolution setting in YouTube as well as the OBS output. Manual selection can be useful when you need predictable dimensions, but it means your encoder must continue sending those configured dimensions when the source changes. A resolution change in OBS without a corresponding adjustment to the manual setting can produce the warning you are trying to clear.
Automatic detection is YouTube’s default recommendation and avoids pinning a manual resolution choice. A manually selected resolution offers control, but makes the match between OBS and YouTube a setting you must maintain. Neither mode makes a 24/7 stream immune to a source or encoder change, so choose the arrangement you can test and monitor reliably.
| Configuration | What to check | Practical trade-off |
|---|---|---|
| Automatic resolution and frame-rate detection | OBS output dimensions and the Live Control Room health message | YouTube detects the incoming settings by default; you have less manual pinning to maintain. |
| Manually selected resolution with a custom key | The key’s selected resolution and OBS output width and height | You control the intended dimensions, but must keep the encoder aligned when sources or output settings change. |
Start OBS and verify its preview
Before you rely on the stream, start OBS and confirm it is sending to the intended YouTube destination. Check the encoder preview in Live Control Room, not just the OBS canvas. Allow time for the preview and health information to appear, then confirm the incoming picture has the expected proportions and that the health message has cleared or changed in a way you understand.
A useful test uses the same kind of material you expect to broadcast. For a bhajan channel, include the actual audio path and representative video or image sources, and check that audio is present and the picture does not change output dimensions unexpectedly when a playlist advances. A single still image may not reveal problems that appear when another file or scene becomes active.
YouTube recommends testing before going live, monitoring health and messages, and checking preview. Its live encoder setup guidance also describes testing the stream and verifying it is accessible. In practice, use a private or otherwise appropriate test arrangement if you need to check the full chain without presenting an unintended public broadcast. Check the channel’s current controls before selecting visibility.
If the warning persists, note whether it appears immediately or only after a source changes. Compare the values again: selected ingestion resolution, OBS output dimensions, and any manual resolution attached to a custom stream key. Avoid repeatedly changing unrelated settings because that makes it harder to identify which change affected the warning.
Check upload capacity and any backup feed
A resolution can be configured correctly and still be a poor choice for a connection that cannot sustain the required upload. Use YouTube’s current bitrate guidance for the selected codec, resolution, and frame rate, then compare the encoder’s outgoing bitrate with the upload capacity available at the location. A download-speed result does not establish that the connection has enough upload capacity.
YouTube’s network guidance recommends leaving 20% of upload bandwidth as headroom. That is particularly relevant if other devices share the connection or if a primary and backup stream are being sent. The YouTube network tips provide the current advice. If the available bandwidth is insufficient for the chosen resolution, YouTube says to consider lowering the selected resolution; check the bitrate guidance again for the new configuration.
Test at the same place and over the same connection that will carry the continuous broadcast. A brief test while other household or business use is idle may not represent conditions overnight, when a router reconnects or other devices begin using the link. You cannot infer reliability from a single speed-test result, and no upload check guarantees that a long session will remain uninterrupted.
If you have configured encoder failover with a primary and backup stream, compare both feeds’ resolution, codec, interlacing, profile, bitrate, frame rate, and audio settings. YouTube lists these as settings to match between primary and backup. Test the failover rather than assuming it will take over correctly. A backup with different dimensions can introduce a new warning precisely when the primary feed drops.
For an always-on stream, the continuous YouTube streaming guide using FFmpeg on Debian covers a different encoder workflow, while the bitrate adjustment guide for a stable YouTube live stream addresses a related capacity setting. Regardless of software, compare the actual outgoing configuration with YouTube’s current requirements and test changes under representative conditions.
Plan resolution changes around the live session
The reviewed YouTube guidance explains the required dimension match, but it does not promise a no-interruption method for changing resolution during an already-running 24/7 broadcast. The safest operational inference is to keep the outgoing dimensions steady for a live session, test an intended change beforehand, and arrange a suitable transition if your encoder cannot apply it safely in place. The exact behaviour depends on the encoder and its configuration.
For example, if a devotional stream currently sends one resolution and you want to move to another for clearer video, test the new output with the same OBS scene, source type, connection, and YouTube settings before scheduling the change. Confirm the preview and health status, then decide how to make the transition without promising uninterrupted playback. If the setup needs the stream to stop and restart, choose a time and communicate that to viewers rather than making an untested live adjustment overnight.
For an ongoing channel, a transition plan is more useful than treating a warning as an invitation to experiment in production. Note the working dimensions, the chosen YouTube setting, and the OBS profile or output values. Keep the prior values available so you can return to a known configuration if a test does not behave as expected.
StreamNeo can remove the need to keep a particular computer running after you have prepared the file and channel, which addresses the practical burden of maintaining an always-on broadcast machine; it does not remove the need to choose and test appropriate YouTube settings for your stream.

FAQ
Does a resolution warning mean I need a new stream key?
No. For an incorrect video size warning, first compare the actual encoder output dimensions with the resolution selected in YouTube’s Ingestion Settings. The available guidance does not establish that a normal resolution change requires a key reset; replace or regenerate a key only when you have a key-specific problem.
Can I change resolution while my 24/7 stream is live?
YouTube’s reviewed guidance does not guarantee a seamless mid-stream resolution change. Test the intended workflow with your encoder first, and plan a transition if it cannot change output safely in place. The result depends on your encoder and configuration.
Should I use automatic or manual resolution in YouTube?
YouTube recommends automatic resolution and frame-rate detection by default. Manual selection is available through a custom stream key and can suit a setup that needs fixed dimensions, provided OBS continues to send those dimensions. Choose the mode you can verify and monitor.
Will lowering resolution always clear the warning?
No. Lowering the selected resolution is an option when bandwidth is insufficient, but an incorrect video size warning specifically calls for matching the sent width and height to the selected resolution. Check the exact message, dimensions, and upload capacity before changing settings.
