3 Ways to Stream a Pre-Recorded Video as Live: OBS, YouTube Premieres and Cloud Playout Compared

What each method asks of your computer and your time, which recorded broadcasts it suits, and how to label the airing so viewers know what they are watching.

Short answer

For a single airing on YouTube only, use a Premiere: no encoder, a countdown, live chat and an honest label. To air a recording while you sit at your desk, or to mix it with a webcam, use OBS with a media source. For scheduled, repeated or multi-platform airings with your computer switched off, use a cloud playout service.

Live, Premiere or rerun: what your viewers are told

Every way to stream pre-recorded video as live runs into one question before any technical one: what will the viewer page say? Platforms show a live badge whether a camera is rolling or a file is playing, so honesty depends on the words you put around the broadcast.

• Premiere. YouTube labels it a Premiere, not a live stream, so viewers know it is the first showing of a finished video.
• Replay or rerun. The platform shows it as live, so the title says “Replay”, “Rerun” or “Recorded session”, with the original date in the description.
• Recording with a live host. Say both: “Recorded lecture, instructor answering in chat”.

At the time of writing, YouTube allows pre-recorded content in a live stream when you own it or have the rights and it follows the Community Guidelines, and Twitch asks for transparent rerun labels. What crosses the line anywhere is telling viewers a recording is happening now. When re-airing a webinar, also cut prompts like “type your question in the Q&A box” if nobody will answer.

Method 1: OBS with a media source

OBS Studio is free, open-source broadcasting software that can play a video file inside a scene. Add a Media Source and choose the file. Tick “Loop” to repeat it or leave it off for a one-time airing, and tick “Restart playback when source becomes active” so the file starts from the beginning when you switch to that scene.

The strength of OBS is live switching: open a product launch on your webcam, cut to the recorded launch video, then come back on camera for questions. No other method here is built for that.

The cost is hardware and attention: the computer and its upload connection must stay on for the whole runtime while OBS encodes live on your CPU or GPU. It sends to one destination unless you add a plugin or a relay service, starts and stops by hand, and retries a dropped connection, but after a crash you restart it yourself.

Method 2: YouTube Premieres

A Premiere gives an uploaded video a scheduled first showing with a countdown and live chat. Afterward it becomes a regular video on the channel. It needs no encoder, no stream key and no computer left running, which makes it the lowest-effort option for a launch video or the first lesson of a new course.

The limits are firm at the time of writing: YouTube only, one airing, and a Premiere label rather than a live stream. For Twitch or Facebook, several videos in a row, or repeat airings, pick another method.

Method 3: a cloud playout service

A cloud playout service stores your videos and plays them to live platforms from its own servers. StreamHouse is one example. You upload files to a media library with folders and previews; every upload gets one processing pass and then carries a Ready status.

From Ready videos you build a playlist, create a “Prerecorded and/or 24/7” stream, add destinations and press Start. The playlist plays once and ends after the last video, or loops around the clock. Your computer can be switched off after the start, and the picture is not re-encoded while live.

• Scheduler: a one-off start time, an optional end time, or both. Nothing recurs, so a weekly class rerun needs a new time each week.
• Live queue: add, remove or reorder videos mid-stream; the current video finishes first, then the new order plays.
• Destinations: YouTube, Twitch, Kick, Facebook and 10 more platforms, plus custom RTMP/RTMPS or SRT. Several at once still count as one stream; all receive the same video, and each needs its own live access.

If a stream drops, StreamHouse relaunches it automatically, up to 10 times an hour, and stops with a notification if it keeps failing. Plans start at $19 a month for one stream at a time, VAT included. Pay-as-you-go credits cost $0.06 per streaming hour at 1080p and never expire: a 90-minute class replay uses $0.09.

It does not do webcam input, scenes, overlays, guests, editing, chat moderation or analytics, so edit before upload and keep OBS for camera work.

The three methods compared

Question	OBS media source	YouTube Premiere	Cloud playout (StreamHouse)
Label viewers see	Live; you add the replay label	Premiere, set by YouTube	Live; you add the replay label
Computer on during the airing	Yes	No	No, once started
Platforms	One without a plugin or relay	YouTube only	14 plus custom servers, several at once
Play once or loop	Both	Once	Both
Reorder mid-airing	By hand	No	Live queue
Scheduled start	By hand	Yes	One-off start, optional end
After a drop	Retries; manual restart after a crash	Not applicable	Relaunches up to 10 times an hour
Webcam in the same broadcast	Yes	No	No
Cost	Free software plus hardware and power	Part of YouTube	From $19/month or $0.06/hour

Prepare the file before any method

• Export the final, finished version of the video; nothing can be edited once it is on air.
• Pick horizontal 16:9 or vertical 9:16, and keep each orientation in its own playlist.
• Match resolution and orientation, and keep the same frame rate across files in one playlist.
• Level the audio before upload instead of counting on the streaming tool to even it out.
• Trim dead air, countdown slates and lines like “we’re live right now”.
• Confirm you own or have licensed everything, background music included. Twitch’s music guidelines allow only music you own or have licensed.
• Watch the last two minutes; exports sometimes end on a black screen or a clipped sentence.
• Write the title, description and original recording date before you schedule.

Common questions

Is it against the rules to stream a recorded video as live?

Not on the major platforms, with conditions. At the time of writing, YouTube allows it if you own the content or hold the rights and it follows the Community Guidelines. Twitch allows content you own or are licensed to use and asks for transparent rerun labels. Kick has no outright ban, but pre-recorded streams are one of the reasons its help center gives for refusing or withdrawing verification and Partner status.

Do I need OBS to broadcast a pre-recorded video?

No. A YouTube Premiere needs no broadcasting software, and a cloud playout service streams from its own servers after you upload. OBS earns its place when the broadcast mixes the recording with something live, such as a webcam intro, scene changes or on-screen overlays.

Can I schedule a recorded live stream to start while I’m away?

Yes, depending on the method. Premieres are scheduled by design. OBS starts by hand on a computer that has to stay on. In StreamHouse you set a one-off start time and an optional end time, and the stream runs from its servers with your computer off.

Will a pre-recorded live stream be saved as a video afterward?

On YouTube it depends on length. At the time of writing, streams longer than 12 hours are not archived as a video, so a two-hour webinar replay is within the limit and a nonstop loop is not. StreamHouse creates broadcasts on a connected YouTube channel with DVR on and set to record, though YouTube does not guarantee the archive.
