If OBS started disconnecting from YouTube after you changed encoder settings, check the outgoing stream settings and the connection signal before resetting anything else. The timing makes the change worth investigating, but it does not prove which setting caused the disconnect.
Start with the encoder and codec, rate control, bitrate, keyframe interval, frame rate, YouTube service and selected stream key. Compare those with the settings YouTube documents, then roll back only the fields you changed and test again. The right comparison depends on your OBS version, operating system and encoder.
Record the current settings and changes
Before editing more settings, make a short record of the configuration that is failing. Note your OBS version and operating system, the encoder name shown for streaming, the exact fields you changed, and when the disconnect occurs. Write down the full error text if OBS or YouTube displays one. Also note whether OBS reports dropped frames or shows a changing connection indicator.
A useful record is specific: “Changed streaming encoder from hardware H.264 to software H.264, then OBS stopped connecting” is more useful than “changed encoder settings”. If you do not remember every change, inspect the current Output settings and compare them with a screenshot, saved profile or other record of the previous configuration, if available. Do not assume an old profile is compatible with the current OBS version or system.
Keep the current values before you alter them. A screenshot or written table makes it possible to restore one field at a time and tells you whether a test actually changed the symptom. If several settings changed together, changing them all back at once may restore the stream but will not show which change mattered.
Capture the failure stage as well. Does OBS fail immediately when you press Start Streaming, connect and then drop, or remain connected while YouTube says it is not receiving data? Those are different clues. An error message or OBS log can help distinguish them; the title alone does not reveal whether the cause is a format mismatch, a connection problem or the wrong event selection.
Check encoder and codec selection
In OBS, inspect the streaming encoder in the Output settings. The exact menu labels and available choices can vary by OBS version, operating system and hardware. Some systems offer hardware encoders as well as a software encoder; a change of encoder can also change which controls are available. Record what OBS actually shows rather than following instructions for a different version.
Then identify the codec being sent. YouTube’s live encoder settings list H.264, H.265 (HEVC) and AV1. Check that the selected encoder is producing a codec YouTube supports and that any codec-specific values match the encoder’s own controls. The name of a hardware encoder alone is not enough to establish which codec or settings are active.
Separate “OBS cannot connect” from “YouTube receives the stream but reports a problem”. If OBS never establishes a connection, check the chosen encoder and its settings, but also verify service and stream-key selection in the next section. If OBS connects yet YouTube reports an ingest or format warning, compare the outgoing format with YouTube’s published guidance. Do not treat a connection failure as proof that the codec itself is unsupported.
If you changed only the encoder choice, try restoring that choice while leaving the other recorded fields alone. If the stream then behaves differently, you have useful evidence; if not, put the original test values back before checking the next field. Avoid switching through several encoder choices without recording them, because that makes it harder to identify what the test established.
Compare rate control, bitrate and keyframe interval
Compare the fields that determine how OBS sends the stream, rather than applying a generic reset. YouTube recommends constant bitrate (CBR), recommends a two-second keyframe interval and says not to exceed four seconds. Those are platform guidelines, not a promise that the same combination will behave identically with every encoder or OBS version.
Bitrate needs context. YouTube publishes recommended ranges by codec, resolution and frame rate; there is no single correct bitrate for every stream. For example, its table gives 1080p at 60 fps H.264 a minimum of 6 Mbps and a recommended 17 Mbps. For AV1 or H.265 at that resolution and frame rate, the table gives a minimum of 4 Mbps and a recommended 12 Mbps. Treat these as YouTube’s recommendations for those specific combinations, not as targets that override the capacity of your connection.
| What to compare | YouTube guidance or diagnostic use | What to do next |
|---|---|---|
| Rate control | CBR is YouTube’s recommended mode. | If you changed it, test the prior value or CBR, where your encoder offers it. |
| Keyframe interval | Two seconds recommended; no more than four seconds. | Compare the active interval, not merely the value shown in an inactive encoder panel. |
| Bitrate | Depends on codec, resolution and frame rate. | Use the matching row in YouTube’s table, then account for stable upload capacity. |
| Codec | H.264, H.265 (HEVC) and AV1 are listed. | Confirm the encoder is actually sending the selected codec. |
If OBS reports dropped frames or a red or yellow connection indicator, prioritise the connection and bitrate branch. The OBS connection troubleshooting guide explains that dropped frames can mean the connection to the remote ingest server is unstable or cannot sustain the selected bitrate, and that too many dropped frames can disconnect a stream. That is a reason to test connection capacity, not to assume every encoder-related disconnect is a network fault.
OBS gives 75% of total upload speed as a starting point for bitrate troubleshooting, subject to stable upload speed and the streaming service’s limits. Treat it as a diagnostic starting point, not a universal setting. If you lower bitrate, make a note of the original value and test whether the dropped-frame signal changes. OBS also describes dynamic bitrate as a workaround when underlying connection issues cannot be resolved; it can reduce quality, so it should not be mistaken for a fix to an incompatible encoder configuration.
When dropped frames are absent, do not keep lowering bitrate without evidence. Check the active rate control, keyframe interval and codec against the platform guidance, and retain the error text or log if the symptom remains. If you change a bitrate to test, keep resolution and frame rate fixed so you can tell what the bitrate change did.
Review frame rate, YouTube service and stream key
YouTube supports up to 60 fps. Check the frame rate OBS is sending and compare it with the resolution and codec row you use in YouTube’s bitrate table. A change in frame rate can make a previously chosen bitrate a poor match to the new output. Do not raise frame rate simply because the platform permits it: use a setting appropriate to your content and equipment, then match the bitrate guidance to it.
Also verify where OBS is trying to send the stream. The OBS YouTube setup resource describes selecting YouTube RTMPS and the intended stream key. Interface wording can change, so follow the labels in your installed version. A valid encoder configuration sent to the wrong service, key or event will not resolve as expected.
In YouTube Live Control Room, confirm that you are looking at the intended broadcast and check whether it shows incoming data or an ingest warning. If OBS appears connected but the event is not receiving data, confirm the selected key and broadcast before changing encoder settings again. If the output settings look compatible but OBS cannot connect, preserve the error details and inspect the service and connection path rather than assuming a format problem.
A stream key is sensitive. Do not paste it into a public support post or screenshot. If you need to ask for help, describe whether the intended key is selected and redact it from any log excerpt or image. Keep the account and event details private while sharing the technical evidence needed to diagnose the failure.
Restore a known-good configuration selectively
If you need to roll back, restore only the fields changed recently, one at a time. Start with the most direct change, such as encoder or codec selection, then test. If that does not alter the symptom, restore or compare the next changed field, such as rate control, bitrate or keyframe interval. This avoids turning an investigation into a broad reset that may introduce new differences.
Use a known-good configuration only if it is genuinely known to have worked on this system with the current OBS version and a comparable YouTube stream. A copied setting from another computer may depend on a different encoder, driver, operating system or connection. If you do not have a reliable previous configuration, use YouTube’s documented values as a compatibility reference rather than treating them as a guaranteed recipe.
Make each test long enough to observe the failure stage and, where possible, include representative motion and audio. A static screen can conceal issues that appear when the content changes. Note whether OBS connects, whether dropped frames appear, what YouTube reports and whether the disconnect recurs. Stop testing if you are about to broadcast unintended content to a public audience; use an appropriate private test workflow for your channel.
There is no reason to delete profiles, reinstall OBS or reset unrelated preferences as a first response. Those steps can remove useful configuration and do not isolate the changed streaming setting. Broader changes are better reserved for a specific diagnostic reason, such as a reproducible error tied to a profile, and should follow a backup of the configuration you want to preserve.
If your channel depends on a fixed video file running continuously and keeping a local computer awake has become a separate source of interruption, StreamNeo can take that file and run the YouTube broadcast while your computer is off; it does not replace diagnosing an OBS setup that you still want to use.
Test the stream and review OBS and YouTube status
After a selective change, test before relying on the stream overnight. Observe OBS’s connection indicator and statistics, especially whether dropped frames appear. In Live Control Room, check stream health and any warnings for the event you intended to use. A successful connection in OBS and an incoming signal in YouTube are related checks, but they are not the same screen and should both be reviewed.
Use the observed signal to choose the next branch. If dropped frames rise or the indicator turns red or yellow, look at upload stability, network conditions and whether the selected bitrate is sustainable. The OBS troubleshooting guide suggests testing another server or service and reviewing network settings or software when connection trouble persists. Those are diagnostic avenues, not proof that you need new hardware or that a particular network setting is at fault.
If OBS stays connected but YouTube reports an ingest or format issue, revisit codec, keyframe interval, bitrate, resolution and frame rate. Compare the complete combination with YouTube’s table; adjusting one value in isolation may not make a combination suitable. If OBS cannot connect or YouTube shows no incoming stream for the intended broadcast, recheck RTMPS, stream key and event selection.
If the problem persists, collect an OBS log from a session that reproduces the failure and note the OBS version, operating system, encoder, exact changes, error text and dropped-frame behaviour. Remove or redact stream keys and other account-sensitive material before sharing it. Avoid claiming a cause until the log or reproducible test supports one; a disconnect that followed a settings change is a useful lead, not a diagnosis.
For a channel that uses a playlist rather than a single scene, keep playback questions separate from outbound connection checks. The guide to moving an OBS playlist stream to another PC deals with preserving a working setup when changing machines. If your concern is whether more than one channel or output belongs on a single account, see running two internet radio channels on one YouTube account; that account question is distinct from an encoder disconnect.
A continuous stream can also fail at the source or reconnect layer rather than at OBS’s outgoing encoder. If you are comparing approaches for an internet radio feed, streaming a radio station to YouTube Live using only audio is a separate format decision. For an FFmpeg-based stream, reconnecting a bhajan stream after an internet drop covers another tool and failure mode; its steps should not be applied as OBS reset instructions.

FAQ
Should I reset all OBS settings after changing the encoder?
Usually, begin by checking and selectively restoring the streaming fields you changed, not every OBS preference. A full reset can remove useful configuration and does not show which change affected the stream. Back up your current settings before considering broader changes for a specific reason.
What bitrate should I use for YouTube?
It depends on codec, resolution and frame rate, so use the matching combination in YouTube’s current encoder settings table. The recommended value is not a substitute for a stable connection that can sustain the stream. If OBS shows dropped frames, test a lower bitrate and observe whether that signal changes.
Does a disconnect after an encoder change mean the encoder is the cause?
No. The timing makes the change worth checking, but dropped frames point towards a connection that is unstable or cannot sustain the selected bitrate, while a format warning calls for checking output compatibility. The error, OBS log and YouTube status help distinguish these cases.
What information should I include when asking for help?
Include your OBS version and operating system, encoder and codec, the settings changed, the exact error and whether dropped frames appeared. Add a log from a session that reproduces the issue if general checks do not resolve it, after removing stream keys and private account details.
