How to Live Stream a Pre-Recorded Video on YouTube (3 Ways)
Three ways to live stream a pre-recorded video on YouTube: Premiere, OBS, or a cloud tool. Verified steps, file specs, and the settings to fix first.
You have a finished video. You want it to go out as a live stream, with a live chat and the red LIVE badge on the watch page.
There are three ways to do that. One is built into YouTube and costs nothing. One is free but ties your computer to the broadcast. One runs from the cloud and keeps going after you shut the laptop.
Most people who search for this want the first one and have never heard of it. Start with the table.
YouTube's rules and LiveReacting's plan limits below were checked against the official pages on August 23, 2026.
Which method should you use?
| YouTube Premiere | OBS + stream key | LiveReacting | |
|---|---|---|---|
| Cost | Free | Free | From $19.99/mo |
| Computer off during the stream | Yes | No | Yes |
| Schedule it in advance | Yes | You still start OBS yourself | Yes, up to 2 weeks |
| Loop it or run it 24/7 | No | Only while the machine runs | Yes |
| Send it to several platforms at once | No | Needs a plugin | Yes |
| Output above 1080p | No | Your hardware decides | Yes, up to 4K |
| Overlays, polls and games | Chat only | You build them yourself | Built in |
| Best for | One video, one time | Free, hands-on setups | Scheduled, repeated or always-on |
First, turn on live streaming
Methods 2 and 3 send a real live stream to YouTube, so the channel has to be cleared for it first. YouTube's own live streaming requirements are short. "To live stream, you need to have no live streaming restrictions in the past 90 days and you need to verify your channel."
| Requirement | Detail |
|---|---|
| Channel verification | Required |
| Live streaming restrictions | None in the past 90 days |
| Age | At least 16. YouTube: "You must be at least 16 years old to live stream." |
| First activation | Up to 24 hours after you request it, once only |
| Streaming from a phone | At least 50 subscribers |
Turn it on in YouTube Studio under Content, then Live, then Get Started. That 24-hour wait is what ruins most first attempts, so request it the day before you need it. Our guide to enabling YouTube live streaming shows the screens.
Method 1: YouTube Premiere (free, nothing to install)
A Premiere plays a video you have already uploaded, at a set time, with a live chat next to it. YouTube describes it as letting "you and your viewers watch and experience a new video together in real time."
- Upload the video in YouTube Studio and keep it Private or Unlisted while you set it up.
- On the Visibility step, choose Public and turn on the Premiere option.
- To start straight away, pick "Set as instant Premiere". To run it later, pick Schedule and set a date and time.
- Share the watch page link. Viewers can set a reminder, and chat replay stays available afterwards.
Three limits come straight off YouTube's Premieres documentation. "Shorts aren't supported for Premieres." Nothing above 1080p works either, and neither does "360/vr180". And "if your account has a Community Guidelines strike, your Premiere won't publish during the penalty period."
A Premiere also runs once. It cannot loop, it cannot reach a second platform, and the file settles onto your channel as an ordinary video afterwards. That is enough for a launch or a one-off event. If you need any of it to repeat, skip to method 3.
Method 2: OBS with a media source
- In YouTube Studio, open Create, then Go live, then the Stream tab, and create the stream.
- Copy the stream key. Our guide covers how to find your YouTube stream key.
- In OBS, add a Media Source and point it at your video file.
- Paste the key into Settings, then Stream, and click Start Streaming.
It works, and it is free. You pay for it in other ways. Your computer runs for the whole broadcast, and your home upload connection carries every frame, so one Wi-Fi drop ends the stream. For anything scheduled, this is the weakest of the three methods, because you have to be at the machine when it starts. If you want the ingest details, see what rtmp://a.rtmp.youtube.com/live2 actually is.
Method 3: Stream it from the cloud, step by step
This is the version where your machine can be off. LiveReacting encodes and broadcasts from its own servers.
1. Create the project. Log in and pick the Simple pre-recorded video template.
2. Upload your video. Click Click to select video file, upload the file in the file manager, then tap it to add it to the project.
3. Connect your YouTube channel. Open Settings with the gear icon, click the plus icon, and authorise the channel you want to go live on. You can add more than one account here and broadcast to all of them at once.
4. Fill in the stream details. Title, description and stream duration. Adjust to video length matches the duration to the file. To run it later, pick a date and time up to two weeks ahead. Tick the live announcement option as well, and YouTube builds the watch page straight away, so you have a link to share before the stream exists.
5. Check the pin, then go live. The pin under the preview sets the starting point, so leave it at 00:00 to play from the beginning. Press Go Live. The stream shows up on YouTube within 5 to 40 seconds.
Once it starts, close the browser. The broadcast runs on LiveReacting's servers.
One limit to plan around. Scheduling needs a paid plan. On the free plan the only button is Go Live.
Video walkthrough
The same five steps, on screen.
What your video file should look like
| Setting | What to use |
|---|---|
| Container | .mp4, .m4v, .mov, .flv, .webm, .ogv, .3gp, .wmv, .avi, .mkv |
| Video codec | H.264 |
| Audio codec | AAC |
| 720p bitrate | 4 Mbps at 30fps, 6 Mbps at 60fps |
| 1080p bitrate | 8 Mbps at 30fps, 12 Mbps at 60fps |
| 4K bitrate | 30 Mbps at 30fps, 35 Mbps at 60fps |
| Maximum file size | 3 GB on Small, 6 GB on Medium, 12 GB on Large, 20 GB on Enterprise, 10 GB on the 24/7 plan |
If your file misses these numbers, upload it anyway. LiveReacting re-encodes it for free, so no converter has to sit on your desktop first.
YouTube settings worth fixing before you press go
Most of these sit under Advanced settings in the stream panel. You set each one once. Changing them after the stream starts is either impossible or ugly, so spend the two minutes now.
| Setting | Why it matters |
|---|---|
| Privacy | Public, Unlisted or Private. Decide before the stream, not during it. |
| Thumbnail | Shows on the watch page while you are live and on the replay afterwards. |
| Disable DVR | Stops viewers rewinding, so everyone is watching the same moment. |
| Made for Kids | The COPPA setting. YouTube turns live chat off on streams set as made for kids, so do not tick it by accident. |
| Category and tags | Feeds YouTube's discovery. Tags take up to 500 characters. |
| Playlists | Adds the stream to a playlist while it is still running. |
| Audio quality | 128k is the safe setting for YouTube. |
| Video bitrate | Leave it on Auto unless you have a reason not to. |
Plan the length too. YouTube archives a live stream automatically only if it ran for under 12 hours. Anything longer leaves you no replay.
What you can still control while it runs
Handing the file to a server does not lock you out of it. Three controls stay live.
- Pause. The video holds on the current frame and the broadcast holds with it. Press Sync with Live to start it moving again.
- Rewind. Drag the pin back to any point, press Sync with Live, and that section plays again.
- Scenes. Cutting to another scene pauses the video. It picks up from the same frame when you cut back.
The third one is what makes a pre-recorded stream feel live. You can cut to a countdown, a poll or a webcam and never lose your place in the file.
Loop it, or leave it running
The same upload can run past a single broadcast.
- Loop one file for an always-on channel. See how to loop a video on YouTube Live 24/7.
- Queue several files in order with a video playlist.
- Turn a back catalogue into a permanent channel with a 24/7 YouTube live channel, no OBS and no machine of your own. There is also a walkthrough for 24/7 streams without OBS.
Send the same video to more than YouTube
One upload can go to several destinations at the same time. Add each account in the same Settings panel. Chat from all of them lands in one feed, which is the part that saves you tabs.
The list covers Facebook Pages and Groups, Twitch, Instagram, TikTok, LinkedIn, and any endpoint that accepts RTMP, HLS or SRT. There is a full walkthrough of multistreaming without the OBS multi-RTMP plugin.
If the time slot is still open, our data on the best time to post on YouTube beats guessing at it.
Add polls, trivia and giveaways
Viewers cannot tell your video was recorded last week, but they can tell whether anything responds to them. Overlays fix that.
| Overlay | What it does |
|---|---|
| Live polls | Viewers vote in the comments. Results update on screen in real time. |
| Countdown timers | Build anticipation before a launch or a reveal. |
| Trivia games | Viewers answer by commenting. Scored automatically, with a leaderboard. |
| Giveaways | Collect entries from comments and draw a winner. |
Add them with the New Layer button, then drag and resize them over the video.
One 2026 change worth knowing
From August 24, 2026, YouTube counts a view the moment playback starts, with no minimum watch time, across uploads, Shorts and live. Public view counts on live streams will go up. YouTube has confirmed the change does not affect earnings or Partner Program eligibility, which still run on watch-time metrics.
FAQ
Can viewers tell that a live stream is pre-recorded?
YouTube puts no label on it. The stream sits in the Live tab with a live chat like any other. The giveaway is silence, so answer people in the chat while it plays.
Does YouTube allow streaming pre-recorded videos as live?
Yes. Nothing in YouTube's rules stops you broadcasting your own recording as a live stream, as long as the content follows the Community Guidelines. Monetization is the part to watch. YouTube's channel monetization policies exclude "content that is repetitive or mass-produced" and reused content with no meaningful difference from the original. One video streamed as live is fine. A channel of interchangeable loops is a monetization risk, which we cover in YouTube's AI content crackdown.
Is live chat available during a pre-recorded live stream?
Yes. It is an ordinary YouTube live chat, and it works the same on a Premiere. The one exception is a stream set as made for kids, where YouTube turns chat off.
Can I live stream a pre-recorded video on YouTube for free?
Yes, two ways. A YouTube Premiere costs nothing and needs no software. OBS is free but ties up your computer. LiveReacting's free plan gives you three streams a month, 30 minutes each at 720p, with no scheduling.
How long can a pre-recorded live stream run on YouTube?
YouTube does not publish a maximum length, so the tool sets the ceiling. On LiveReacting that runs from 1 hour on the Small plan to 24 hours on Enterprise, and the 24/7 plan has no duration cap. Remember that streams over 12 hours are not archived automatically.
What is the difference between a Premiere and a pre-recorded live stream?
A Premiere plays a file YouTube already holds. With a live stream, an encoder pushes the video to YouTube in real time. That gap explains the limits. A Premiere caps at 1080p, runs once and stays on YouTube. A live stream can loop, run at 4K and reach several platforms at once.
Do I need OBS to stream a pre-recorded video on YouTube?
No. A Premiere needs nothing but YouTube, and a cloud tool runs in your browser. If you already use OBS or vMix and only want the overlays, LiveReacting also runs as a browser source inside them.
Start with your next video
Match the method to the job. If one video goes out once, use a Premiere and save your money. If it has to run on a schedule, repeat, or never stop, upload it and let the cloud hold the stream.
