Use OBS Studio on your Mac to send a prerecorded video to YouTube Live, then enable looping so the file starts again when it finishes. For a playlist, use OBS's VLC Video source instead of a single Media Source, and keep the Mac, OBS, video files and internet connection available for the broadcast to continue.
Before you begin, check that your channel can livestream, prepare the video files, and decide whether you want to operate the encoder locally or use a cloud-based service. A Mac gives you direct control, but it must remain available and monitored for as long as the stream runs.
Check YouTube live eligibility first
YouTube requires the channel to be verified and to have no live-streaming restrictions in the previous 90 days. First-time live-stream enablement may take up to 24 hours, so do not leave this step until the moment you want to publish a devotional stream, local news loop or study channel.
You can review the current requirements in YouTube's live-streaming eligibility guidance. If the feature is not enabled, complete the process and wait until YouTube confirms that the channel can go live.
You also need the prerecorded material itself to be suitable for the channel. Check that you have the right to use the video, music, images, voices and any graphics in the file. A video being stored on your Mac does not by itself give you permission to broadcast it.
Before adding anything to OBS, play the complete file in a normal Mac video player. Check that the picture fills the intended frame, the audio is present, and the ending does not contain an unwanted pause or blank screen. If you are preparing a bhajan or devotional channel, for example, decide whether a visible transition at the loop point is acceptable or whether the file needs editing first.
For a longer sequence, put the files in one folder and use clear filenames. This makes it easier to identify the correct media source later and reduces the chance of changing a live scene by mistake. If the content is stored on an external drive, make sure the drive is connected before opening OBS and remains available during the broadcast.
Create an OBS scene on the Mac
Install OBS Studio from the official OBS Project download page, then open it on the Mac. OBS works with scenes and sources: a scene is the layout being sent to YouTube, while a source is an individual item such as a video, image or audio device.
Create a new scene with a name that describes its purpose, such as Morning Bhajans or Study Loop. In the Sources panel, add the video source you intend to use. Keeping one broadcast in one clearly named scene makes it easier to check what is live before you press Start Streaming.
For a straightforward setup, the scene can contain only the video. If you need a logo, schedule, text label or background, add those as separate sources and place them above the video in the source list. Preview the scene at normal size rather than relying only on a thumbnail. Look for cropped edges, black bars, unreadable text and audio levels that are too low or too high.
The Mac is doing more than playing a file. OBS reads the media, renders the scene and encodes the result before sending it to YouTube. The load depends on the video, the scene and the chosen output settings. Close applications that are not needed, avoid using the Mac for unrelated video work, and disable settings that might put the computer to sleep during a scheduled broadcast.
Do not treat sleep and shutdown as interchangeable. A Mac that is shut down is not running OBS and cannot continue sending the feed. A local setup therefore needs the computer powered on, OBS open, the media available and the network connection working for the whole period.
If you are estimating whether the Mac is suitable for several channels, read the practical considerations in how much CPU and RAM FFmpeg needs for a 24/7 YouTube stream. The exact result depends on your scene and encoding settings, so use a test rather than assuming that one Mac will handle every arrangement.
Add one video with Media Source and enable Loop
For one file that should repeat, add a Media Source to the scene. In OBS, choose the local file and enable Loop in the source properties. When playback reaches the end, OBS starts the same file again.
The important distinction is that looping is configured in OBS, not in YouTube Studio. YouTube receives the encoded feed that OBS sends; it does not select the local file or decide when that file should restart.
A typical setup is:
- Select the scene in OBS.
- Add a Media Source.
- Choose the video file on the Mac.
- Enable Loop.
- Confirm that the source is visible and that its audio is active.
- Watch the transition at the end of the file in the OBS preview.
OBS documents Media Source behaviour and its looping controls in its Media Source guide. The guide also covers options such as restarting playback when the source becomes active. Use those options deliberately: restarting a source when it becomes visible can be useful for a short segment, but it may also restart the file unexpectedly if you change scenes.
Keep the source path stable. Renaming or moving the file after configuring OBS can leave the source unable to find the media. If you replace the file, use the source properties to select the new version and test it again before starting the public broadcast.
A single Media Source is usually the clearest choice when one complete video is intended to repeat. It is also easier to troubleshoot because there is one file, one loop setting and one point at which you can inspect the transition. The limitation is editorial: if you want several programmes in sequence, you will need either one edited file or a playlist source.
Use VLC Video for a playlist
For multiple files, OBS provides a VLC Video source. This source is designed for a playlist and includes a Loop Playlist option. VLC must be installed on the Mac for the source to work.
Add the VLC Video source to the scene, create or select the playlist, add the files in the order you want them played, and enable Loop Playlist. The playlist might contain several event replays, a set of music videos or a group of lessons. Play the sequence in the OBS preview before connecting it to YouTube.
The distinction matters:
| Setup | Best for | Loop control | Main trade-off |
|---|---|---|---|
| Media Source | One complete video | Loop repeats that file | Simple to check, but not a multi-file schedule |
| VLC Video | Several files in sequence | Loop Playlist repeats the playlist | More flexible, but VLC and every file must remain available |
Do not add the same files to both sources unless you intend to layer or switch between them. If VLC is missing, incorrectly installed or unable to read one of the files, the playlist may not behave as expected. Test the first file, a transition between files and the final file before treating the playlist as ready.
File compatibility can vary with the container, codec, audio track and frame characteristics. Common formats such as MP4, MOV, MKV and WebM are listed in OBS documentation, but that does not mean every file will play identically on every Mac. A file that plays in one application may still need testing in the actual OBS source.
If you are building a playlist of event replays rather than repeating one programme, how to stream a playlist of event replays on YouTube Live covers the planning side. For a channel that needs captions, a logo or lyrics, build those elements into the scene and inspect them across the full playlist.
Create an encoder stream in YouTube Studio
Open YouTube Studio and go to the Live Control Room. Choose the encoder workflow, then create a new stream or select an existing one. YouTube's encoder workflow provides the connection details that OBS needs: a stream URL and a stream key.
An encoder converts the video from your scene into a format YouTube can receive. YouTube explains the process in Create a YouTube live stream with an encoder. Follow the current Studio labels because the arrangement of the control room can change.
Give the stream a useful title and description, select the visibility you want for the test, and set the scheduled details if you are preparing a public broadcast. A private or unlisted test lets you inspect the feed without immediately directing viewers to it.
Treat the stream key as a password. Do not put it in a screenshot, paste it into a public support post or send it in a group chat. If you think it has been exposed, reset it in YouTube Studio and update OBS with the replacement key.
At this stage, do not assume that creating the stream means the Mac is already broadcasting. You still need to enter the connection details in OBS, start the encoder and wait for YouTube to receive enough information to show a preview.
Enter the stream URL and key in OBS
In OBS, open Settings, then the Stream section. Select YouTube as the service if that option is available, or use the custom server arrangement where the YouTube stream URL and key are entered separately. Copy the values from YouTube Studio carefully rather than typing them from memory.
The URL tells OBS where to send the feed. The key identifies the stream destination. Keep both values private, particularly the key. Save the settings and return to the main OBS window.
Before starting, confirm the correct scene is selected, the media source is visible, and the audio mixer shows activity when the video plays. Check that the stream is not accidentally using a microphone, webcam or desktop capture source that you did not intend to publish.
When ready, select Start Streaming in OBS. YouTube Studio should begin showing the incoming encoder feed in the Live Control Room. Starting OBS is the beginning of the encoder connection; YouTube's control room may still require you to confirm or start the public broadcast according to the workflow you selected.
If YouTube does not show the feed, check the URL and key first. Then check whether the Mac is connected to the internet, whether the selected scene has a visible source, and whether another application is already using the same key. Resetting the key is appropriate if it may have been exposed, but it will not fix a missing video file or an offline network.
Preview, check stream health and test the upload path
Do a representative test before announcing the channel. Include the busiest part of the scene, not just a still frame. A devotional loop with moving text, a local news sequence with several overlays, or an ambience video with continuous audio can place different demands on the Mac and the upload connection.
YouTube recommends RTMPS for RTMP-based streaming and recommends constant bitrate encoding. Use the current YouTube live encoder settings and bitrate guidance for the resolution and frame rate you intend to use. Do not copy one bitrate into every setup: the suitable choice depends on the output dimensions, frame rate, encoder configuration and sustained upload capacity.
Watch the Live Control Room preview before making the stream public. Check the picture, audio, title, visibility and intended latency. Then inspect stream health while the test is running. A feed can look correct in the local OBS preview while the upload is dropping frames or arriving with interruptions at YouTube.
The useful test is not simply whether the video starts. Let it run through a loop boundary, or through several playlist transitions, and observe whether the source restarts cleanly. Check whether the audio continues, whether the scene remains in the correct order and whether the Mac stays responsive enough to manage the broadcast.
Keep the Mac connected to power and configure its energy settings so it does not sleep during the planned run. Make sure the network connection is stable in the place where the Mac will operate. If the stream is important, have a person responsible for checking it rather than assuming that a successful start means the entire night will be trouble-free.
For channels serving viewers in India or elsewhere on a variable connection, compare the upload path with the chosen output settings before committing to a long broadcast. The guide to preventing buffering in a 24/7 worship stream is useful when the content is correct but viewers report pauses or quality changes.
Plan for archives and very long broadcasts
A continuous live broadcast is not the same thing as a permanent recording. YouTube says streams under 12 hours can be automatically archived, while a stream that exceeds 12 hours may not be captured at all. If the recording matters, do not make the YouTube archive your only copy.
YouTube recommends keeping a local archive backup. You can enable recording in your local workflow and check that the Mac has enough available storage for the intended run. An external SSD for video recording is an optional storage choice, not a requirement for going live; choose storage based on the size of the files and the length of the recording rather than buying a drive simply because a stream is live.
Long broadcasts also have DVR considerations. YouTube says rewind may be limited or unavailable beyond 12 hours. If viewers need to go back to an earlier prayer, lesson or news segment, explain that a very long live stream may not provide the same rewind behaviour as a shorter broadcast.
A local recording adds another task for the Mac. It uses storage and may add processing work, so test it with the same scene and output settings. If local recording is essential, check the resulting file after the test instead of assuming that an OBS recording was written correctly.
You can also split a schedule into separate broadcasts where that suits the channel, but do not describe that as a way to remove YouTube's current archive rules. Check the official archive and DVR guidance before relying on any particular workflow.
Decide whether the Mac should run the encoder
OBS on the Mac is useful when you want direct access to local files, scene layouts and playlist changes. It can be a good fit for a creator who is present at the workstation, can keep the Mac powered and connected, and wants to adjust the broadcast locally.
The trade-off is operational. The Mac, OBS, media files and network connection all remain part of the chain. A power cut, sleep event, disconnected drive, application problem or lost connection can interrupt the feed, and the person running the channel must decide how to respond.
A cloud encoder changes where the continuous operation happens. YouTube lists Gyre as a cloud-based option for continuous prerecorded streams that does not require a dedicated PC. That listing establishes the category, not current pricing, plan limits, partner terms or any guarantee about service performance. Compare the provider's current documentation yourself before relying on it.
StreamNeo removes the need to keep a dedicated Mac running for this particular workflow: upload the video once, add the YouTube stream key, and the broadcast can run from the cloud with automatic monitoring and restart if it drops. It is YouTube-only, so it is not a replacement for a encoder, and you should still check the live output and retain copies of important media.
| Option | Where the feed is prepared and run | Useful when | Responsibility to plan for |
|---|---|---|---|
| OBS on Mac | On your Mac with local files | You want local scene and playlist control | Keep the Mac, files, OBS and connection available |
| Cloud encoder | In a hosted service | You do not want a dedicated computer running | Check the provider's current terms, controls and monitoring |
The choice is not about making a claim that one route always works better. Choose local OBS when hands-on control matters and the Mac can be supervised. Choose a cloud workflow when avoiding a computer running continuously is the main requirement.

FAQ
Can I loop one prerecorded video on YouTube Live from a Mac?
Yes. Add the local file to an OBS Media Source and enable Loop. The Mac must remain powered on with OBS, the file and the network connection available while the broadcast runs.
Should I use Media Source or VLC Video in OBS?
Use Media Source when one file should repeat. Use VLC Video when you need a playlist of multiple files and want to enable Loop Playlist; VLC must be installed and the playlist should be tested before going live.
Can I shut down the Mac after starting the YouTube stream?
No. The Mac is the local encoder in this setup, so shutting it down stops OBS from sending the feed. If you do not want a dedicated computer running, consider a cloud encoder instead and check its current terms and controls.
Will YouTube always save a 24/7 stream as an archive?
No. YouTube says streams under 12 hours can be automatically archived, while streams longer than 12 hours may not be captured. Keep a local backup if the recording matters, and check YouTube's current archive and DVR guidance before planning a long broadcast.
