YouTube may reject a live stream when the width and height sent by your encoder do not match the resolution selected in Live Control Room’s Ingestion Settings. Start by reading the exact stream-health message, then compare those two settings before changing anything else.
The guidance reviewed for this issue does not specify a separate resolution rule for a stream just because it runs 24/7. A continuous channel still needs compatible encoder settings, enough stable upload capacity, and monitoring; matching dimensions is an important first check, not a guarantee that every rejection will be fixed.
Why YouTube may reject the resolution
YouTube’s live-stream troubleshooting guidance says the video sent by the encoder must use the height and width of the resolution selected on the Ingestion Settings page. If the selected setting and actual output differ, YouTube may report an incorrect or unsupported video size. For example, selecting 1920 × 1080 in the stream settings while the encoder sends 1280 × 720 creates a mismatch even if the picture looks acceptable on your local preview.
The important distinction is between the resolution you intended to send and the dimensions the encoder actually outputs. A source file may be 1080p, but an encoder scene, scaling option, or output profile can reduce it to another size. Conversely, the encoder can send a larger frame than the setting selected in YouTube. Check the output that leaves the encoder, rather than relying on the file’s properties or the canvas size alone.
YouTube normally detects encoder settings automatically. Its live encoder settings guidance describes manual resolution selection for a custom stream key when you need it. Unless there is a reason to set it manually, automatic detection is the documented default; if manual settings are in use, verify the chosen resolution there as well as in the encoder.
A resolution warning can appear alongside another stream configuration problem. The health panel may identify bitrate, codec or format, audio, scan type, frame rate, keyframe interval, or primary and backup feed mismatch. Treat the wording in Live Control Room as evidence about the current fault, not as a generic signal to purchase new equipment or to lower every setting.
Read the exact stream-health message
Open the stream in Live Control Room and look at its stream-health panel. Note the precise text and timestamp of the message. YouTube’s stream health troubleshooting page explains that health messages can point to specific problems; critical errors may stop an event from starting or affect viewers, while moderate issues can reduce quality. The message that remains visible after a setting change is more useful than a remembered paraphrase of an earlier warning.
If the message names “Incorrect video size (resolution)” or similar wording, begin with width and height. Write down the exact dimensions the encoder reports as output and the resolution selected for the stream in Ingestion Settings. Do not confuse a preview window’s display size with its encoded output. A preview can be resized on your monitor without changing the transmitted frame.
If the message names a different issue, resolve that issue on its own terms. A feed can have the correct dimensions but insufficient bitrate, an unsupported format, interlaced rather than progressive video, or a frame rate the selected setup does not support. The official troubleshooting guide also calls out keyframe intervals and differences between primary and backup streams. Avoid changing several unrelated controls at once: if the health message clears or changes, you want to know which adjustment mattered.
For a useful troubleshooting note, record the message, the time it appeared, encoder output width × height, codec, frame rate, bitrate, and the selected ingestion resolution. This gives you a before-and-after comparison and makes it easier to ask for help from an encoder’s support team if the output field is unclear. It is also more actionable than saying only that YouTube “does not like” the resolution.
Compare encoder dimensions with Ingestion Settings
Make a direct comparison, using numbers rather than labels such as “HD” or “Full HD”. The setting names can hide differences between output sizes, and a profile label does not prove what dimensions are being sent. Confirm both values in pixels, in width × height order.
| Check | What to read | What to do if it differs |
|---|---|---|
| Encoder output | Actual width and height sent by the encoder | Set the output to the intended dimensions, or choose a matching YouTube setting |
| Ingestion resolution | Resolution selected for this stream in Live Control Room | Verify it is the setting intended for the encoder’s output |
| Manual stream-key resolution | Manual resolution for a custom stream key, if enabled | Confirm it agrees with both the encoder and the ingestion selection |
| Backup feed | Width, height, and related stream settings | Align it with the primary feed if you use failover |
Suppose your encoder output reads 1280 × 720 and Live Control Room is configured for 1920 × 1080. You have two straightforward paths: set the encoder to output 1920 × 1080 if it can do so reliably, or choose the matching 1280 × 720 selection in YouTube. The right choice depends on the source, encoder capacity, connection and picture detail you need. Do not choose the larger number simply because it sounds better.
If you use OBS or another encoder, inspect its streaming output settings rather than assuming the base canvas determines the transmitted dimensions. A canvas can be one size and the scaled output another. Check for rescaling, output profiles, and any custom resolution associated with the stream key. If a setting is greyed out or overridden, determine which profile controls the final output before changing the YouTube side.
For a prerecorded loop, distinguish the source video from the live output. A file may have one aspect ratio or pixel size while the encoder scales it to a different stream output. The useful question is not only “What resolution is my file?” but “What width and height does the encoder send to YouTube?” If you are building a looping setup, the guide to making a 24/7 study playlist stream with FFmpeg may help you identify the output configuration in a software-based workflow.
Make the output dimensions match
Choose which setting to change based on what your equipment and connection can sustain. You can make the encoder’s output match the selected ingestion resolution, or select the resolution in YouTube that matches the encoder. Either way, verify the final actual dimensions after applying the change. Some encoders require you to restart the stream output before the new size takes effect.
Do not confuse matching dimensions with a recommendation to always stream at the highest available resolution. YouTube’s encoder-settings page gives bitrate recommendations that depend on codec, resolution, and frame rate. For H.264 at 1080p and 30 fps, the table lists 5 Mbps minimum and 14 Mbps recommended; for H.264 at 720p and 30 fps, it lists 3 Mbps minimum and 8 Mbps recommended. These are YouTube’s published settings guidance, not a guarantee that your internet connection can maintain them throughout a continuous broadcast. Check the current table for your actual codec and frame rate rather than transferring a figure from one mode to another.
Think about picture detail and continuity together. A devotional image with a fixed camera may not need the same resolution as a fast-moving local news segment, but either stream can fail if the output and selected setting disagree. If upload capacity fluctuates, YouTube’s guidance says to consider a lower selected resolution when there is not enough bandwidth for the chosen one. A lower setting that remains stable can be more useful than an ambitious one that repeatedly degrades or drops.
For primary and backup feeds, align the configurations. A backup encoder that changes dimensions, codec, frame rate, or other key settings can introduce a separate problem when YouTube switches feeds. If failover matters to your channel, test it deliberately rather than assuming that the backup is interchangeable because it has the same content. YouTube’s live-streaming tips include testing failover and monitoring stream health.
Verify the selected ingestion resolution
In Live Control Room, open the stream’s settings and inspect Ingestion Settings. Confirm the selected resolution for the current stream, not merely a value you remember from a previous broadcast. If the encoder uses a custom stream key with manual settings, inspect that key’s resolution selection too. The key and the encoder profile can both shape what is sent, so check the active configuration rather than a saved preset that might not be in use.
YouTube’s default automatic detection is intended to identify encoder settings. Manual selection is useful when your workflow needs it, but it creates another place where a mismatch can be introduced. If manual resolution is selected, make a note of it and align the encoder output exactly. If you return to automatic detection, verify the resulting stream dimensions and health message rather than assuming the change resolved the issue.
Check that you are editing the correct stream and ingestion configuration. Channels that run separate programmes or mood-specific feeds may have different stream keys and settings. A value corrected for one channel or one scheduled event may not carry over to another. If you manage several loops, the guide to separate 24/7 YouTube radio streams for different music moods is relevant to keeping distinct broadcasts organised; treat each stream’s active settings as its own check.
Once the values agree, save the settings and allow the encoder to reconnect or restart its output if required by your setup. Watch Live Control Room for a fresh health message. A successful preview is useful, but keep the panel open long enough to see whether the dimensions continue to be accepted after the feed settles.
Retest and monitor the live feed
Test changes before depending on them overnight. Start the encoder, check the current health message, and verify that the stream preview appears as expected. Observe whether the reported issue clears, persists, or changes to another message. If it changes, follow the new message rather than repeatedly adjusting resolution.
For a 24/7 channel, a brief successful preview is only the first check. Keep an eye on stream health during the period when you would normally leave the channel unattended, and look for interruptions, bitrate warnings, or a return of the size error. A test helps expose configuration problems; it cannot prove the connection will remain stable indefinitely. YouTube recommends choosing settings reliable for your connection and monitoring the feed.
If the selected resolution is correct but the warning remains, revisit the exact output fields and confirm that a scaling filter or profile did not override them. Then check the other parameters identified in the message: codec and container format, audio format, progressive scan, frame rate, bitrate, keyframe interval, and backup-feed consistency. YouTube’s encoder guidance recommends a two-second keyframe frequency and says not to exceed four seconds. Use the current official page for the selected protocol and codec, because requirements and recommendations belong to particular modes.
Keep a short change log: original health message, the two dimensions, what you changed, and what happened after reconnecting. This is particularly useful when a stream runs unattended or more than one person maintains it. If you need to switch from a computer-based setup to a workflow that does not depend on keeping your own machine running, StreamNeo can remove the task of leaving that computer on, but the file and YouTube stream configuration still need to be suitable for the channel.
For an existing loop, avoid changing the resolution and replacing the content at the same moment unless both changes are necessary. Separating the actions makes the result easier to diagnose and can reduce disruption to a working broadcast. If your concern is changing what viewers see while keeping a nature channel running, see how to replace the video in a 24/7 YouTube nature stream without ending it; content replacement and resolution troubleshooting are different operations.
What 24/7 does—and does not—change
The reviewed YouTube resolution guidance concerns the encoder output, selected ingestion resolution, and other stream settings. It does not describe a special resolution limit that applies just because a live stream is continuous. Do not infer a 24/7-only cap from a general size warning, and do not assume that an ordinary live-stream setting is automatically suitable for all-day operation without testing.
Continuous use changes the practical stakes. A resolution and bitrate that work for a short test may be harder to sustain through changing network conditions, device load, or a long unattended period. Your choice should account for the source material, the detail viewers need, available upload capacity, and whether a second feed uses identical settings. It is sensible to start with a configuration you can monitor and repeat, then make one deliberate adjustment at a time.
No purchase is established as the fix for a resolution rejection. The documented first step is to correct stream configuration and inspect health messages; YouTube’s live-streaming tips also say that expensive equipment is not needed to get started. If the output dimensions are wrong, changing to a more costly encoder does not by itself ensure that the transmitted dimensions match. Resolve the settings question first, then consider equipment only if you have a separate, evidenced limitation.
The useful diagnostic details to keep at hand are the exact health message, encoder’s actual width and height, selected ingestion resolution, codec, frame rate, and bitrate. With those details, you can separate a dimension mismatch from bandwidth or format trouble and describe the situation clearly if you need support.

FAQ
Does YouTube have a special resolution limit for 24/7 streams?
The reviewed official guidance does not identify a separate resolution rule merely because a stream runs continuously. It describes matching the encoder’s sent width and height to the selected Ingestion Settings resolution, plus checking other stream requirements. Check YouTube’s current guidance if your setup or error message points to a specific restriction.
Which should I change: the encoder or YouTube’s ingestion setting?
Change whichever setting is inconsistent with the configuration you can reliably run. You can adjust the encoder output to match YouTube, or choose the YouTube resolution that matches the encoder. Then verify the actual output dimensions and check whether the health message changes.
If the dimensions match, is the rejection fixed?
Not necessarily. The message may relate to bitrate, codec, frame rate, audio, scan type, keyframe interval, or a mismatch between primary and backup feeds. Read the current health message and troubleshoot the named issue rather than treating a dimension match as a guarantee.
Should I buy a new encoder to fix this?
A purchase is not established as the remedy for a size mismatch. First check the output dimensions and selected ingestion resolution, then test the stream and review any remaining error. Consider new equipment only if you identify a separate limitation that settings changes cannot address.
