A reusable YouTube stream key lets you send future broadcasts to YouTube using the same encoder credential. Create a custom key in Live Control Room, save it in your encoder, and select it again for later sessions.
That is separate from reusing a previous stream’s settings, and neither action keeps one live event open indefinitely. If a broadcast runs longer than 12 hours, its archive may not be captured and DVR may be limited or unavailable, so plan for those outcomes rather than assuming the replay will be complete.
What a reusable custom stream key does
A stream key is the credential your encoder uses, along with YouTube’s stream URL, to send a feed to your channel. In practical terms, it tells YouTube which incoming video stream to accept. A custom stream key can be selected again for later broadcasts, so you do not have to create a different encoder credential for every session.
The key does not contain your video, create a schedule, or keep an encoder running. It is not the live event itself, nor is it a promise that a particular watch page will remain live. The encoder still has to send a valid feed, and the corresponding stream in YouTube’s Live Control Room must be started and managed as needed. A reusable credential makes repeat setup simpler; it does not remove those operating steps.
Treat the key as private. Anyone who obtains it may be able to send a feed using it, which can interrupt or replace the intended broadcast. Do not paste it into public notes, screenshots, chat messages, or a support post. If you think it has been exposed, reset the key in Live Control Room and update the encoder with the replacement. YouTube says channel owners and managers can reset a key; editors and viewers cannot.
For a channel that runs a daily bhajan loop, for example, a custom key can stay configured in the encoder while you start a new session when needed. The key is unchanged, but the stream session and its event management are still separate matters. If you are deciding whether your channel’s recurring schedule should run on a local device or another arrangement, the practical constraints discussed in keeping a YouTube playlist schedule running on a Raspberry Pi in India are relevant to that broader operating choice.
Create a custom key in Live Control Room
In YouTube Studio, open Create, choose Go Live, then open the Stream tab. Find the stream-key selector and choose the option to create a custom stream key. Set the options you need, save it, and make a note of which key you intend to use for this channel. YouTube’s live stream settings help page describes the custom-key workflow and current controls.
Interface labels can change, so if a button or menu appears in a different place, use the current Live Control Room help rather than guessing at a similarly named control. Make sure you are working in the correct channel if you manage more than one. A key created while signed into a different channel will not serve the channel you intend to broadcast from.
Choose settings to match the encoder and the type of feed you will send. This is not the moment to assume the key will convert an unsuitable output into a compatible one. The encoder must use the stream URL and output settings appropriate to the broadcast. If you need to revisit resolution and frame-rate choices, see the guide to YouTube Live settings for 1080p at 30 fps; the right output depends on the source and your production requirements.
After saving, keep the credential somewhere controlled and accessible to whoever operates the channel. If only one person runs the stream, a private password manager or another protected record is safer than a shared document with broad access. If a team needs it, agree who can retrieve or replace it and how encoder updates will be made. Do not assume that a key remains safe merely because it has been used for a long time.
Save and select the key in your encoder
Open the encoder you use for the broadcast and enter the YouTube stream URL and the custom stream key in the appropriate fields. The URL identifies the destination; the key authenticates the incoming feed. Save the encoder profile if you expect to use the same production settings again, but distinguish that profile from the key itself. An encoder profile may store sources, scenes, audio routing, and output choices, while the key is one credential within its connection settings.
When preparing a new session, check that the intended key is selected and that the encoder is connected to the correct YouTube channel. Start the encoder’s feed, then inspect the Live Control Room preview and stream health. YouTube’s encoder setup instructions describe sending an encoder feed and, for scheduled workflows, waiting for the preview before selecting Go live. Follow the workflow shown for your session rather than assuming that sending video always makes the public event live automatically.
Before relying on the setup overnight, test it during a time when you can watch the whole chain: the source plays, audio is present, the encoder is sending, YouTube receives the preview, and the intended watch page is accessible. Check from another device or browser if practical. A preview visible only on the operator’s computer does not prove that the public-facing channel is displaying the right stream.
A saved key does not prevent an encoder process from stopping, a computer from sleeping, or a network connection from failing. If your feed is generated by a playlist on a small computer, test what happens after a disconnect rather than relying on the key to recover it. The troubleshooting steps in fixing Raspberry Pi FFmpeg disconnects when the network drops address a different layer of the problem: reconnecting the feed is not the same as reusing its credential.
For people who do not want a personal computer to be the part that must remain on and watched through the night, StreamNeo can remove that specific operating burden by turning an uploaded video into a YouTube live broadcast while your own computer is off. It does not change the distinction between a reusable key and a live event, or the archive and DVR caveats below.
Reuse settings from a previous stream
Live Control Room has another action that sounds similar but does something different. In the Manage tab, you can choose a previous stream and select Reuse settings to create another stream with copied metadata, settings, and stream key. This is useful when a recurring programme uses the same title structure, description, visibility choices, or other configuration and you want a new stream based on that setup.
Reusing settings is a stream-creation workflow, not simply a way of keeping a key in an encoder. The new stream has its own management context; you should review its title, description, privacy, and other details before starting. Do not assume that copied metadata is still accurate. A title that names yesterday’s prayer session or a description with an old schedule may be wrong for today’s broadcast.
The two choices can be summarised this way:
| Workflow | What carries forward | Useful when | What still needs attention |
|---|---|---|---|
| Keep a custom key selected in the encoder | The encoder credential used to send a feed | Your encoder configuration should persist across recurring sessions | Create or select the intended stream, start it correctly, and check the feed |
| Select Reuse settings for a prior stream | The previous stream’s metadata, settings, and key in a new stream setup | You want another stream based on a prior event’s configuration | Review copied details, confirm privacy, and manage the new event |
These workflows can overlap: a reused-settings stream can carry the same key, and an encoder can keep that key saved. But they answer different questions. “Can the encoder keep using this credential?” is a key question. “Can I make another stream with yesterday’s configuration?” is a reuse-settings question. Neither means that the same event remains open without end.
If you broadcast changing episodes or announcements, using a new stream based on prior settings may make it easier to maintain a distinct event and current title. If your output is a continuous ambience or devotional loop, a persistent encoder profile may be more convenient, but you still need a clear process for starting, ending, and checking sessions. Decide whether each broadcast should have a new event before you settle on a routine.
A recurring key does not keep one event open forever
“Always-on” can mean that viewers can regularly find a live channel, or it can mean a single uninterrupted live event that never ends. A reusable key helps with the first kind of operation by allowing the encoder to use the same credential in future sessions. YouTube’s documented key and encoder workflows do not establish that one event can remain open indefinitely, nor do they guarantee uninterrupted transmission.
There are several separate pieces in a live broadcast: the source that produces the picture and sound, the encoder that sends them, the network path, and the stream or event managed in YouTube. A key is only one piece. A power cut, app failure, changed source file, or network drop can stop the feed even if the key remains valid. Conversely, sending a feed does not by itself prove that the intended event is publicly live or that viewers can access it.
For a channel with a repeating schedule, write down the operator’s sequence: select or create the stream, confirm the encoder key and destination, start the feed, verify the preview, make the event live when the workflow requires it, and check the watch page. Include how to stop or replace the broadcast and who can reset a compromised key. Test the sequence before handing it to another person; a written procedure is more useful than relying on one operator’s memory.
If reliability depends on automatic recovery, treat that as a separate requirement to test in the encoder or the operating arrangement you choose. YouTube’s key reuse guidance is not a claim that the encoder restarts, that a dropped connection reconnects, or that a stream continues without observation. For a local setup, consider what a router restart or power interruption does to the device and source. A practical guide to keeping a church YouTube stream running during Indian power cuts is useful when power continuity is part of the real problem.
Understand the 12-hour archive and DVR caveats
A long broadcast creates two separate viewer and operator concerns: whether YouTube captures an archive, and whether viewers can rewind during the live transmission. The thresholds in YouTube’s guidance concern those features; they should not be mistaken for a universal statement that every live event must end at 12 hours.
For archives, YouTube says a stream shorter than 12 hours can be automatically archived, but if a stream exceeds 12 hours it may not be captured at all. That is a possibility, not a promise of an archive below the threshold and certainly not a guarantee above it. If a complete replay matters for a satsang, local news bulletin, class, or music session, keep a local recording and check that it is actually being written and has enough space. YouTube’s archive live streams guidance explains the archive caveat.
DVR is a different feature: it lets viewers rewind while a live stream is still in progress. YouTube warns that DVR capabilities may be limited or unavailable for streams longer than 12 hours, and viewers may therefore be unable to seek back as expected. Do not advertise an all-night or multi-day stream as fully rewindable without testing and checking current guidance. The DVR help page sets out this limitation.
If preserving the whole programme matters, treat local recording as part of the production plan rather than an afterthought. Confirm the recording starts with the stream, monitor available storage, and test that the file can be opened. A local file can protect against missing archive capture, but it is not a substitute for checking whether the public stream remained live or whether viewers could rewind it.
For very long broadcasts, consider whether the channel’s audience needs one continuous event or a sequence of distinct sessions. Separate sessions may make titles and watch pages easier to organise, but this changes how viewers find the programme and how you manage the schedule. Verify the current YouTube workflow and the impact on your channel before changing a routine. The reviewed guidance does not establish a maximum runtime for every event, so do not infer one from the archive and DVR warnings.
A practical checklist before making it routine
Before relying on a repeated setup, confirm the pieces independently. The key should be the custom key you intend to reuse, the encoder should be sending to the intended channel, and the Live Control Room should show the expected preview. Check the title, visibility, and event status as well as picture and sound. If another person operates the channel, make sure they know which saved profile and key are current.
For a long-running station, keep a local recording if you need a complete copy, and verify it during a test rather than after an important programme. Decide what happens if the feed stops: who notices, how the encoder is restarted, whether the same event can be resumed in your workflow, and when a new stream should be created instead. Those are operating decisions, not properties supplied by a reusable key.

FAQ
Can I reuse the same YouTube stream key in OBS?
Yes. Create a custom key in Live Control Room and select that same key in OBS for a later session. Check that OBS is sending to the right channel and that the relevant stream or event is set up and started as required.
Is “Reuse settings” the same as reusing a stream key?
No. Reusing a custom key means selecting the same encoder credential again. Reuse settings creates another stream based on a previous stream’s metadata, settings, and key, so review the copied details before going live.
Can one YouTube live stream stay on all the time?
A reusable key does not show that a single event can stay open indefinitely, and YouTube’s key guidance does not guarantee continuous operation. If your goal is an always-available channel, plan for recurring session management and test how your encoder and YouTube workflow behave when a feed stops.
Will YouTube archive or provide DVR for a stream over 12 hours?
Do not count on either. YouTube says a stream exceeding 12 hours may not be captured as an archive, and DVR may be limited or unavailable for streams longer than 12 hours. Keep a local recording if preserving the full programme matters.
