To replay conference sponsor presentations as a YouTube Live broadcast, create an encoder stream in YouTube Studio and send it a repeating feed from OBS Studio. The YouTube player’s loop control only affects playback for an individual viewer; it does not turn a finished upload into a live broadcast.
Before you schedule the stream, confirm that you have permission to rebroadcast every talk and all the material within it. Then test the files, audio, connection and repeat behaviour before sharing the watch page with viewers.
Confirm rights and prepare the sponsor presentations
Start with the recordings and the permissions, not with OBS. The fact that a presentation was shown at your event does not by itself establish that you may broadcast it again afterwards. Ask the relevant organiser, speaker and rights holders what uses were authorised, and retain the permissions and any conditions alongside the files.
Check each recording as a complete piece of content. A speaker may have permission to show a slide deck at the conference without having permission to distribute it in a public livestream. Music used as a walk-on track, video clips embedded in slides, photographs, charts, product demonstrations and third-party logos can all have separate rights or usage terms. Sponsor approval of its own presentation does not necessarily cover material supplied by a speaker or another company.
YouTube says it scans live streams for third-party content. If it detects material, it may replace the broadcast with a placeholder and warn the channel; unresolved use can lead to an interruption or termination. YouTube also notes that a licence may not be enough to prevent an interruption if a rights holder has not allowlisted the channel through Content ID. Read the current YouTube guidance on live-streaming copyrighted content and ask the relevant rights holder about allowlisting where it applies. Do not assume that silence or a previous event screening is permission to rebroadcast.
Make a simple clearance record for each file: who approved it, what channel or platform the approval covers, whether there is an end date, and any restrictions on edits or sponsor placement. If a rights holder says the material cannot be reused, leave it out. If permission is unclear, resolve that before creating a public stream rather than treating a test or unlisted broadcast as a substitute for approval.
Prepare a final, reviewed set of files in the order you want viewers to see them. Use clear file names and keep a separate copy of the approved versions so an operator does not accidentally select an unfinished edit. Preserve the speaker’s name, sponsor name and useful event context. A brief slate between talks can explain the transition or identify the next presentation; it is an editorial choice, not a YouTube requirement.
Watch the complete sequence, or at least verify every file and transition deliberately, before going live. Check that audio is present at an appropriate level, that slides and captions remain legible, and that no edit exposes a private discussion or an unintended screen. A documented order makes it easier to set up an OBS playlist and confirm that the correct presentation is playing at the end of each item.
Create or schedule the YouTube Live stream
In YouTube Studio, use Create → Go Live to make a new stream or schedule one for later. Choose a title and description that explain that the broadcast is a replay of conference presentations, and select the intended visibility. YouTube supports public, private and unlisted streams; choose according to whether viewers should be able to find the page, whether you are testing, and how you plan to share access.
Check that the channel is eligible to livestream before promoting the event. YouTube’s live-streaming tips say the channel must be verified and have no live-streaming restrictions in the preceding 90 days. This is a platform eligibility condition, not a guarantee that a particular stream will be approved or remain uninterrupted. Review the current YouTube live-streaming tips and the channel’s Studio status in advance.
When you create the event, YouTube gives you a watch page and encoder settings for that broadcast. The page is where viewers watch; OBS is the encoder that sends the actual audiovisual feed to YouTube. A scheduled event does not start replaying files by itself. You still need to connect an encoder, start its output and, where the workflow asks for it, start the live event in Live Control Room.
Decide whether you need a public rehearsal or a private technical test. Keep in mind that changing visibility does not cure rights issues: use only material you are authorised to transmit, even during testing. If you are preparing several sponsor presentations, schedule enough time for a full run-through and make sure the people who will operate the stream can access the correct YouTube Studio account.
For the broader source setup, OBS Media Source settings for looping Telugu songs on YouTube Live covers related looping controls. The same basic source idea applies to presentation recordings, but use this guide’s rights and event checks for sponsor content.
Configure OBS Studio as the encoder
Install and open OBS Studio on the computer you will use for the test. OBS is a software encoder: it combines the selected video and audio sources into a live feed for YouTube. It is not the same thing as putting a video on YouTube and asking its player to repeat it. The files must be available to OBS while the broadcast is running, and the computer and network connection must remain available for the duration of a locally run stream.
Before loading the presentations, set up a scene for the broadcast. A scene can contain the video source and any other elements you deliberately want, such as a holding slate or a small event label. Keep the layout simple enough that it does not cover slide content. Use OBS’s preview to inspect the canvas at the intended output size, and avoid adding overlays whose use has not been approved by the sponsor or event organiser.
Set the output resolution and frame rate to suit the source material and the available upload connection. YouTube publishes current encoder recommendations, including codec, bitrate and keyframe settings, in its encoder settings guide. Follow the current guidance rather than relying on an old preset copied from another event. A high output setting cannot compensate for an unstable upload connection, and an unnecessarily demanding setting can make the feed harder to sustain.
A conference recording may be a slide presentation with little motion, but that does not mean you should guess at settings. Check what OBS is actually sending and compare it with YouTube’s stream health information during the test. If the feed drops frames, becomes blurry or has audio out of sync, adjust the encoder configuration or connection and test again before inviting an audience.
If the stream is intended to continue after the event team has left, consider what happens if the local computer sleeps, loses power or closes OBS. A local OBS setup depends on that machine and its connection; make plans for someone to monitor it and for a responsible operator to stop the stream when the planned run ends. For a different operating model, how to choose a 24/7 YouTube streaming service for a regional-language channel in India sets out questions to consider when comparing locally operated and hosted workflows.
Add local media sources and enable looping
In OBS, add the presentation files as media sources. For one video, add a Media Source, select the approved local file and enable Loop in the source properties. When playback reaches the end of that file, OBS can start that source again. This is the direct approach if one presentation, or one preassembled video containing several talks, is meant to repeat.
If the talks are separate files and must play in a fixed sequence, a VLC Video source can use a playlist with Loop Playlist enabled. OBS’s documentation notes that VLC Video requires VLC to be installed. Add the files in the intended order, then inspect the playlist carefully: an extra file, a duplicate, or an accidental change of order can make a sponsor presentation appear at the wrong point in the cycle.
| OBS source approach | Fits this situation | What to verify |
|---|---|---|
| Media Source with Loop | A single recording, including a preassembled sequence | The selected file is the cleared final version and starts again as expected |
| VLC Video with Loop Playlist | Several separate recordings that should repeat in a fixed order | VLC is installed, the playlist order is right, and every item plays through |
These are workflow differences, not measured performance comparisons. OBS supports a range of media file types, including MP4, MOV, MKV and AVI, but a listed format does not guarantee that every file will behave as expected on a particular computer. Test the actual exports you plan to broadcast. If OBS shows a black frame, no sound or an unexpected aspect ratio, inspect the file and source settings rather than discovering the issue after the stream is public.
Looping a source or playlist does not promise a seamless transition. Watch what happens between presentations: there may be a pause, a blank frame or an abrupt change in audio. If that would confuse viewers, edit in an intentional transition or slate, then recheck the final export and its permissions. For guidance specifically about VLC in an always-on arrangement, see how to set up VLC as a source for an always-on YouTube stream.
Listen to the source through OBS as well as watching its preview. Confirm that narration is audible, that separate audio tracks are not missing, and that the end of a file does not leave an unintended silence before the next presentation. A long repeated sequence can make a small audio problem recur throughout the broadcast, so fix it in the source or playlist before starting.
Enter the YouTube stream URL and key
Return to YouTube Studio’s Live Control Room and open the encoder settings for the stream you created. Copy the stream URL and stream key into OBS’s stream settings. YouTube’s encoder workflow uses these values to tell the encoder where to send its feed and which stream to connect to. Use RTMPS where the encoder supports it; YouTube describes it as encrypted RTMP in its encoder recommendations.
Treat the key as a credential. YouTube Help describes stream keys as like a stream’s “password and address”. Do not paste it into a public event document, show it in a screenshot, or send it to a sponsor who does not need to operate the encoder. Limit access to the people responsible for the broadcast, and use YouTube Studio to manage or reset the key if it has been exposed. The stream key walkthrough for a 24/7 stream can help if you need a separate reminder of where to find it.
Check that OBS is configured for the intended YouTube service and that the correct event’s URL and key are in use. If you have several scheduled streams, it is easy to connect to the wrong one. Avoid keeping multiple copies of the key in notes or production documents; identify the event by its title in a way that does not reveal credentials.
A successful connection from OBS means the encoder is reaching YouTube, not that the broadcast is already ready for viewers. You still need to inspect the Live Control Room preview, confirm that the right presentation is visible and audible, and follow the start sequence shown for that event. If YouTube does not receive a signal, check that the stream URL and key correspond to the selected event, then review OBS’s connection status and YouTube’s current encoder instructions.
Preview, test and start the broadcast
Do a test run before announcing the watch page. YouTube recommends configuring an encoder at least two hours ahead and starting it at least 15 minutes before a scheduled event. Those recommendations give you time to find problems; they are not a substitute for an actual rehearsal. Run the same files, source order and output settings you intend to use, and keep the stream private or unlisted if that suits the test and your access plan.
In Live Control Room, check the preview for picture and sound, then watch the viewer-facing page on a phone as well as on the operator’s screen. Confirm that slide text is readable at the smaller size and that the stream is not simply showing a frozen opening frame. Listen for clipped speech, very quiet audio or transitions that cut off a presenter. Check YouTube’s stream health indicators and OBS’s own status rather than relying on one green light alone.
For a useful loop test, observe a file reaching its end and the next item beginning; if the playlist contains just one file, confirm it restarts. You need not wait through a full programme if that is impractical, but do not infer repeat behaviour solely from seeing the Loop box checked. Record any problems, change one setting at a time, and rerun the part of the sequence that was affected.
When the test is clean, start the encoder and follow Live Control Room’s prompt to go live if it has not started automatically. Check that the public or intended audience page is showing the broadcast, then monitor the beginning closely. Assign a named operator to watch playback and respond if the source stops, the connection falls away or YouTube warns about content. If rights detection interrupts the feed, do not keep restarting the same material without addressing the warning.
Plan how and when the stream will end. When the replay period is over, stop the OBS output and end the broadcast in Live Control Room. A repeating source will not know that the conference campaign has finished or that a sponsor has asked for its presentation to be removed. An operator should check the end time, stop the feed deliberately and confirm the event is no longer live.
Understand the YouTube archive limit
YouTube’s encoder setup guidance says streams under 12 hours are automatically archived. Treat that as a bounded platform statement, not as a promise that a longer broadcast will be preserved in full. If viewers need access to the recordings after the live event, plan a separate approved archive or upload, and verify the result in YouTube Studio rather than relying on the live page alone.
The archive is also distinct from the repeating broadcast. OBS sends the loop as a live feed while it is running; YouTube’s player loop setting does not make that feed, and the existence of a live watch page does not guarantee that every file will be available afterwards in the form you expect. Check YouTube’s current encoder setup and archive instructions before deciding how long to run the event.
A practical schedule can reduce uncertainty. If the main purpose is to give attendees a limited replay window, choose an end time that fits the programme and the archive guidance, then have someone stop the encoder and close the event. If the goal is a longer always-on channel, consider the operational demands separately: rights duration, monitoring responsibility, the repeat’s editorial suitability and the archive plan all still matter. For a continuous schedule of previously recorded services, how to stream a church’s archived services on YouTube Live discusses related planning considerations.

FAQ
Can I use YouTube’s player loop button to make sponsor videos go live?
No. The player loop control affects playback for a viewer and does not send a prerecorded feed to YouTube as a live broadcast. Use an encoder such as OBS to play the approved files and transmit them to a YouTube Live event.
Can I rebroadcast a sponsor talk just because it was shown at the conference?
Not necessarily. Confirm permission for the recording and for its slides, music, embedded clips and other third-party material, including any limits on channel, audience or duration. A live-stream interruption is possible if YouTube detects third-party content, so resolve rights and any Content ID allowlisting questions before the broadcast.
Does an OBS loop guarantee that transitions will be seamless?
No. A Media Source can repeat one file, and a VLC Video source can repeat a playlist, but you should test the actual transitions. Add an intentional slate or edit the sequence if a pause or abrupt change would be confusing.
Will YouTube keep the whole stream as an archive?
YouTube says streams under 12 hours are automatically archived. Do not assume that statement promises a complete archive for a longer stream; check current YouTube guidance and verify any recording you need in Studio.
