To show sponsor slides between prerecorded sessions on YouTube Live, send one continuous programme from an encoder such as OBS Studio. Create separate scenes for each talk and for the sponsor material, then switch scenes at the planned breaks; YouTube does not insert sponsor slides automatically.
This gives you control over what viewers see between sessions, but it also makes the operator responsible for timing, playback and audio. Build the sequence in advance and rehearse it from the start of a talk through the next talk before inviting viewers to watch.
Plan the sessions and sponsor placements
Start with a running order, not with the OBS controls. Write down each prerecorded session, its expected duration, the point where it ends, the sponsor material that follows, and what should happen after the final talk. This makes the transitions part of the programme rather than an improvised response to a video ending.
For example, a community conference might play an opening talk, show a sponsor slide, play a second talk, then show a rotating set of sponsor graphics before the closing session. Decide whether each sponsor interval is a single fixed image or a sequence of images, and agree the order with the event organiser. A slide in the stream is a placement, not a promise of audience attention, sponsor results or any particular exposure.
Check the media before assembling scenes. Confirm that each talk file opens, has the intended audio, and starts at the point you expect. If a file includes a long silent lead-in or closing credits, decide whether those are part of the programme. Do not assume the encoder will know where you want a transition simply because a file has reached its end.
Also decide who operates the stream. A single person can run a modest programme, but they will need to watch the preview and make scene changes while keeping to the running order. If another person can monitor timings or communicate with the operator, agree a simple cue such as “talk ending” and “switch to sponsor” before the rehearsal.
Keep a copy of the running order beside the controls. Include the scene names as they appear in OBS, so the operator does not have to infer which item comes next. Clear names such as “Talk 1”, “Sponsor – single slide” and “Talk 2” are easier to use under pressure than generic labels such as “Scene 2”.
Schedule the YouTube Live event
Schedule the event in YouTube Studio’s Live Control Room. Set its title, privacy and event details, then use the scheduled stream’s server URL and stream key in OBS. YouTube’s encoder setup guidance describes this process. Treat the stream key like a password: do not publish it in a slide, share it in a public message or include it in a recording of your desktop.
A scheduled event gives you a watch page to share and lets viewers set a reminder where that feature is available. It does not prepare the programme or add sponsor scenes. Those remain in the outgoing encoder feed. If you have not used a scheduled encoder stream before, follow YouTube’s live-streaming setup guidance and confirm you are working on the intended event rather than another scheduled stream.
Set up the encoder early enough to resolve issues without an audience waiting. YouTube’s live-streaming tips recommend setting up an encoder at least two hours in advance and starting it at least fifteen minutes before the event. Treat that as preparation guidance rather than a guarantee that every problem will be found in that window. Your rehearsal should cover the entire chain: OBS playback, sponsor changes, audio, the YouTube preview and the scheduled event itself.
When the event is scheduled, note the date and time, privacy setting and correct watch-page address in the production notes. If the event is unlisted for a private technical rehearsal, make sure you understand which event will be public on the day. Keep the stream key out of those notes unless they are stored and shared securely.
Build a scene for each prerecorded session
In OBS, create a scene for each talk that needs its own playback and transition point. Add the corresponding local file as a Media Source. OBS’s Media Sources guide explains the source’s playback options, including looping and restarting when the source becomes active. For a one-time conference session, check that the playback settings match the running order rather than relying on a default that might replay a talk.
Give the talk source a clear name and place it correctly in the scene. Check that the picture fits the canvas without cropping titles or speaker faces, and confirm that the source’s audio is audible at a sensible level. The final mix can sound different from playback through your editing software, so listen through OBS and the YouTube preview during rehearsal.
Separate scenes make it straightforward to decide exactly when one talk ends and the sponsor material begins. They also give you more operator responsibility: if a talk runs longer than expected, the operator must adjust the next cue. For a small programme, that trade-off is often preferable to trying to build a sequence whose automatic timing does not match the actual event.
OBS also has a VLC Video source that can play a playlist, but VLC must be installed. A playlist can be useful if the talks should play in order without an operator switching between each one. Separate Media Source scenes are generally easier when you need to insert a sponsor scene at a particular boundary or hold a talk while someone resolves an issue. Choose based on the cueing you can reliably manage, not on the number of clicks in the initial setup.
For more context on file playback in a continuous broadcast, see the guide to using prerecorded yoga classes in a YouTube Live playlist. The format differs, but the practical questions about source playback, sequencing and what viewers see between files are relevant here too.
Add a sponsor scene with an image or slideshow
Create a separate sponsor scene. For one sponsor card, add an Image source and select the prepared graphic. For several sponsor cards, use OBS’s Image Slide Show source, which can rotate images in an ordered set. The OBS image-sources documentation covers the available image options, including slideshow controls.
A single image is simpler to rehearse: the operator switches to it, holds it for the agreed interval, then switches to the next session. A slideshow can suit an event with several sponsors or a longer break, but it introduces timing decisions. Choose whether images change automatically or manually, in what order they appear, whether the set loops, and what transition is used. Check the result in the actual scene rather than assuming the files will display in the intended order.
Prepare graphics at a consistent canvas size and keep important text away from the edges. Use legible sponsor names and a restrained amount of copy; viewers may be watching on a phone or television, and a dense card is difficult to read at a glance. If a logo has a light or dark background, test it against the scene so it remains visible. Confirm that the organiser has supplied the approved artwork and that the order matches the agreement.
Avoid adding more visual elements than the break needs. A logo, short description and event-specific call to action may be enough. The slide should be useful to a viewer who has just watched a talk, not a substitute for a separate sponsor agreement or a claim about what the sponsor will receive. You control the placement in the programme, but you cannot control whether a particular viewer watches it.
If slides rotate automatically, write down the duration and test it over the full interval. If the operator changes them manually, include those cues in the running order. Consider a neutral holding graphic for any extra time needed between a session and the next planned scene; avoid leaving the audience looking at an editing desktop or an unintended blank screen.
Set the transitions between talks and sponsor slides
The core sequence is simple: talk scene, sponsor scene, next talk scene. In OBS, choose a scene transition such as a cut or fade, and set the transition behaviour you want for the programme. The OBS overview of scenes and sources explains how these building blocks fit together. A cut is immediate; a fade takes time and can make a change feel less abrupt, but it does not replace a clear cue from the operator.
Use the OBS preview and program workflow to inspect the next scene before putting it on air. The operator can select the sponsor scene in preview, check that the correct graphic is loaded, then make the transition when the talk has ended. This reduces the chance of accidentally showing an unprepared scene, but only if the operator understands which view is preview and which is currently being sent to YouTube.
Rehearse every transition, not only the first one. Play each talk far enough to observe how it ends, switch to the sponsor scene, hold it for the planned interval, and then move to the next session. Test the end-of-file behaviour: depending on the source settings, a finished file might stop, remain on its last frame or behave differently from what you expected. Decide whether to cut promptly, show a holding image or wait for an agreed cue.
Listen across scene changes as well as watching them. A sponsor image can be silent while a talk scene has audio, and a source that continues playing in the background may create unexpected sound when you switch away. Check the OBS audio mixer and the stream preview for a clean hand-off. Do not rely only on the meters: listen on another device if possible, because a local monitoring path can conceal a problem in the live output.
If you are also managing a recurring channel, the black-screen troubleshooting guide for looping YouTube streams is useful background on why playback needs a real test. A one-off event has different timing needs, but a rehearsal can expose the same sort of source or end-of-file surprises before viewers arrive.
Rehearse the full programme and check the preview
Run a complete test sequence before event day. Use the actual files and sponsor graphics, not temporary placeholders, and follow the running order from the opening scene through the final session. Confirm that every video starts from the intended point, the sponsor image or slideshow displays in order, audio is present where expected, and the transitions are visible in the outgoing programme.
Start the encoder and check that the scheduled event’s preview receives the composed feed before you select Go live. YouTube’s advice on testing and monitoring a live stream is a useful checklist for checking the preview and stream health. Confirm the public or unlisted watch page on a separate device, and check sound and picture there rather than assuming the OBS window is an exact substitute.
Write down what to do if something fails. If a talk does not start, the operator might switch to a sponsor or holding scene while checking the source. If a slide is wrong, move to the approved replacement rather than leaving an editing window visible. If the encoder feed is not appearing in the preview, do not tell viewers the event has begun until the issue is understood.
On show day, keep the cue sheet, correct YouTube event and OBS project available. YouTube recommends beginning the encoder setup well ahead of time; its timing advice is a useful prompt to avoid configuring everything in the last few minutes. Have the operator check stream health during the broadcast and confirm each scene change on the watch page where practical. A preview that worked in rehearsal does not remove the need to monitor the live event.
After the final item, end the stream in Live Control Room and stop the encoder. YouTube says streams under twelve hours are automatically archived, but check the event’s recording afterwards rather than assuming the archive is complete or ready to share. If the event is intended to remain available, confirm its privacy and watch-page settings before sending the link to attendees.
When a programme must keep running after the operator’s computer is switched off, a cloud-run broadcast can remove that specific local-machine burden; StreamNeo turns an uploaded file into a YouTube live stream, though a manually cued event with different sessions and sponsor breaks still needs its scenes, timing and rehearsal planned.
Keep sponsor breaks distinct from YouTube’s break slate
YouTube’s Live Control Room includes a “Take a Break” away slate for temporary breaks. It is separate from the sponsor sequence you build in OBS. A break slate may be useful if the programme pauses unexpectedly, but it is not a playlist of approved sponsor placements and does not replace switching to your own sponsor scene between talks.
This distinction matters because the outgoing encoder feed is what viewers receive. If you want an event-specific graphic to appear at a planned point, put that graphic in the programme and switch to it deliberately. If you are simply stepping away from the controls, use the appropriate break feature only after checking what it displays and how it affects the broadcast.
The production path described here does not require a dedicated physical product: OBS and YouTube provide the documented software workflow. The trade-off is operational rather than automatic. You assemble the sources, decide the order, check the preview and make or rehearse the transitions yourself. A bitrate checklist for OBS and YouTube Live can help with the wider encoder setup, although it does not determine when sponsor slides appear.

FAQ
How do I show sponsor slides between sessions on a YouTube livestream?
Send one continuous feed from an encoder such as OBS to the scheduled YouTube Live event. Build separate scenes for each talk and for the sponsor graphic or slideshow, then switch between them at the planned breaks. YouTube does not automatically insert the sponsor material.
Can I play prerecorded videos during a YouTube Live stream?
Yes. Add each local video file as an OBS Media Source and send the composed programme to YouTube through the encoder. Test the file’s playback, audio and end behaviour in advance; the live event receives the encoder’s output, not a separate file playlist managed by YouTube.
How do I switch scenes between videos and sponsor slides?
Use separate OBS scenes and switch from the talk scene to the sponsor scene, then to the next talk. You can use a cut or fade transition and the preview/program workflow to check the next scene before sending it to the audience. Rehearse the entire sequence so the operator knows the cues.
Should I use a static sponsor image or an Image Slide Show?
Use a static Image source when a single card is enough and you want the simplest hand-off. Choose Image Slide Show when several graphics should appear in an ordered rotation, and test the change mode, duration, order and loop behaviour. In either case, agree the placement with the event organiser and avoid promising sponsor results.
