To switch between pre-recorded videos during a YouTube Live stream in OBS, put each clip in its own scene using a Media Source, then select the scene you want while the stream is running. If you want OBS to play a sequence from one source instead, use VLC Video and build a playlist; use Studio Mode when you want to preview a scene before sending it to viewers.
The right approach depends on whether you need to choose each clip yourself or let a playlist advance. Neither approach guarantees seamless playback: prepare and test the files, scene behaviour, audio and YouTube preview before relying on them during a broadcast.
Choose a source: one clip or a playlist
OBS gives you two useful ways to play local files. A Media Source is the simpler fit for an individual clip in a scene. VLC Video is intended for a list of files managed together, and it depends on VLC being installed. The difference is not only how many clips you can add; it is also who decides what plays next.
| Need | OBS approach | What to account for |
|---|---|---|
| Select a particular clip or segment yourself | Media Source in a separate scene for each clip | You choose the next scene; check whether playback restarts when it becomes active. |
| Play a prepared sequence from one source | VLC Video with a playlist | VLC must be installed, and playlist settings determine looping, shuffle and visibility behaviour. |
| Prepare a change before viewers see it | Either approach, arranged in scenes | Studio Mode lets you prepare a scene, then transition it to the live output. |
Media Source is built into OBS and works with a range of audio and video formats. OBS lists video formats including MP4, TS, MOV, FLV, MKV, AVI, GIF and WebM, and audio formats including MP3, AAC, OGG and WAV. Those are supported formats, not a promise that every file encoded in them will behave identically on every computer. If a file fails to play or its audio is missing, check the file itself and test it in OBS rather than assuming the extension tells the whole story. See OBS’s Media Sources guide for the source’s controls and format information.
A VLC Video source is useful when you want one source to manage several items as a playlist. It offers playlist loop and shuffle controls, along with a visibility behaviour setting that affects playback when the source is not visible. VLC is a dependency: the source requires VLC, and OBS notes that 64-bit OBS requires 64-bit VLC. If you would rather avoid that extra dependency, separate Media Sources in separate scenes make each file easier to select directly.
For a programme with labelled segments—an opening, a talk, then a closing bhajan—individual scenes make the operator’s choice explicit. A playlist can suit a fixed sequence of tracks where the next item should follow the previous one. If your aim is uninterrupted repetition of a single file rather than changing clips, the choices are different; the guide to looping a video on YouTube Live without a VPS covers that related setup.
Add clips as sources or scenes
Before building scenes, put the intended media files somewhere you can find them and give them recognisable names. Names such as 01-opening.mp4 and 02-interview.mp4 are easier to identify in a source list than a folder full of generic filenames. This is a practical housekeeping step, not an OBS requirement. Avoid moving or renaming files after you have configured the scene unless you are ready to relink the source and test it again.
For independently selectable clips, create a scene for each clip or programme segment. In a scene, add a Media Source, choose the local file, and set its properties for the way that segment should behave. If an existing scene already contains your usual layout—such as a logo or background—make sure the clip is placed and sized as intended, and decide whether it should cover that layout or sit within it. OBS’s Sources Guide explains how sources are arranged in scenes.
Check the Media Source options rather than assuming the default fits your programme. Looping controls whether a file repeats. Restart playback when the source becomes active determines whether the clip starts from the beginning when you switch to its scene. Hiding when playback ends affects what happens once a clip finishes, while hardware decoding can be enabled when supported. The useful setting depends on the clip: a short announcement may need to restart on every activation, while a segment you intend to play once should not accidentally repeat.
If a source is meant to stop at the end, check what viewers should see after it finishes. A blank or frozen-looking frame may be confusing if the next item is not ready. You can prepare a holding scene, or coordinate the end of one clip with a manual switch to the next scene. Test what OBS actually shows when playback ends; do not infer the result from a checkbox name alone.
For a playlist, add a VLC Video source and populate its playlist with the files in the intended order. Decide whether the list should loop or shuffle. Shuffle may be suitable for music or ambience, but is a poor fit where the opening, middle and closing sections need to occur in a fixed order. Check the source’s visibility behaviour too, especially if it sits in a scene that may be hidden while you prepare another scene.
The playlist keeps the clips together in one source, but it gives you less direct scene-level control over choosing a specific item at a specific moment. Separate scenes take more organisation: each selectable segment needs a scene and a clear label. That trade-off is similar to planning a news replay stream’s export settings, where a segment’s place in the programme matters as much as whether the file plays.
Connect OBS to YouTube Live
To send OBS output to YouTube, retrieve the stream URL and stream key from YouTube Studio’s Live Control Room, then enter them in OBS’s stream settings. YouTube’s instructions for creating a live stream with an encoder describe the Live Control Room setup. The exact labels in the interface may change, so use YouTube’s current help page if the screens differ from what you see.
Treat the stream key as sensitive. YouTube describes stream keys as similar to a stream’s password and address. Do not show the key on screen, include it in a public screenshot, or share it with someone who does not need access. If it is exposed, consult YouTube Studio’s current controls and guidance rather than continuing with a key others may have seen. The live stream settings help page explains where stream settings and key options are managed.
In OBS, choose the YouTube-compatible connection method and enter the URL and key supplied in Studio. Before starting, verify that you are using the intended stream event and not a different scheduled broadcast. A correct connection sends the OBS programme output to the event, but it does not check whether the selected scene contains the right clip or audio. Confirm those separately in OBS and in YouTube’s preview.
For a one-off stream, the initial connection can be part of your pre-event checklist. For a regular channel, keep a written procedure for locating the right event, selecting the relevant scene and checking the preview, but do not put the key itself in an openly accessible document. If you need more background on a continuous recorded programme, the guide to creating a continuous YouTube Live stream for a Marathi podcast covers the broader format; this article focuses on switching clips inside OBS.
Switch scenes during the broadcast
Once OBS is sending to the correct YouTube event, switching scenes changes the programme OBS is producing. In the ordinary workflow, select the scene you want in OBS’s scene controls. When Studio Mode is off, the selected scene is the one being sent to the live output, so take care not to select a half-built scene by mistake.
For more deliberate operation, assign a hotkey to each scene in OBS settings. A distinct shortcut for each segment can be easier to use than searching a long scene list while watching the broadcast. Choose keys that are easy to remember and unlikely to be pressed accidentally during other work. Test each shortcut before the event, including the transition from every scene you expect to use. A regular keyboard is sufficient; a programmable keypad is an optional convenience, not a requirement.
Scene names should describe the content and order clearly. For example, Opening, Interview, and Closing are more useful in a live control list than Scene 1, Scene 2, and Scene 3. If scenes contain similar-looking material, add a distinct preview image or other visual cue when practical. The aim is to reduce the chance of choosing the wrong clip, not to add decoration for its own sake.
A scene switch is a control action, not a guarantee that playback will be uninterrupted. A large file, a slow machine, a missing source path, or a clip that has not been tested can affect what appears. If your show needs a precise sequence, rehearse the sequence with the actual files and the intended scene order. Keep a simple fallback scene available, and know how to select it if the chosen source does not appear as expected.
For a playlist source, playback follows the playlist settings rather than a scene choice for each file. You can still organise the playlist inside a scene, but it is a different operating model: scene switching selects among prepared programme states, while playlist playback advances through its configured items. If you are adapting the approach to episodic content, the article on switching between podcast episodes in OBS is a closely related example of making episodes separately selectable.
Preview transitions with Studio Mode
Studio Mode separates the scene viewers see from the scene you are preparing. The live side remains the current output, while the preview side lets you choose and inspect the next scene. This helps you check that the intended file, layout and audio source are selected before the change reaches the broadcast.
A typical change is: leave the current programme on the live side, select the next scene for preview, confirm it looks right, then use Transition to send it to the live output. OBS also supports configured Quick Transitions. The overview documentation describes Fade and Cut as available transitions, with other built-in choices and adjustable durations. Use a cut when the programme calls for an immediate change; use a fade when a gradual visual change suits the material. There is no universal transition or duration that fits every clip.
Studio Mode changes how you operate; it does not play a clip in advance merely because it appears in preview. Check the source’s restart behaviour and whether playback starts when the source becomes active. If you need to know how the first seconds look, test that source in a rehearsal and watch the preview. Confirm the actual transition behaviour rather than expecting a previewed scene to behave exactly like a scene that has already been live.
Before a planned segment change, identify the scene by name, inspect the preview for the right content and check that the transition control is ready. For a regular show, a small printed or on-screen running order can help an operator pair each segment with its scene. Keep it separate from any stream key or account credentials. This reduces reliance on memory when attention is divided between OBS and the Live Control Room.
Test playback, audio and stream health
Test with the same files, scene order and connection you expect to use for the broadcast. Start with each clip individually: verify that it opens, fills the intended area, and plays for the expected duration. Listen for audio in OBS and confirm the correct audio source is active. A video that looks right in the preview can still have muted, missing or unexpectedly loud audio.
Then test the actual change between scenes. Confirm that the next clip starts at the point you expect, that the previous scene does not remain visible in a layer, and that any intended fade or cut looks acceptable. Test what happens at the end of a clip and when you return to a scene you have already used. These checks matter because loop and restart settings can make a source behave differently on re-entry.
Use YouTube’s Live Control Room preview and stream health indicators as another check, not a substitute for OBS testing. YouTube’s guidance on encoder settings, bitrates and resolutions includes configuration advice; choose settings for your intended output and available upload connection, then verify the result with a test. Avoid copying a bitrate or resolution from another channel without considering your own output configuration and connection.
During the broadcast, keep an eye on both the OBS programme and YouTube’s status information. YouTube recommends monitoring audio and video quality while live, and its live streaming tips provide further guidance. Watch for a stalled image, unexpected silence, a wrong scene, or a stream-health warning. If something goes wrong, choose a known-good scene or pause to diagnose rather than repeatedly changing settings without knowing what they do.
For a channel that is expected to run overnight, the person operating it should know which scenes are safe to leave active and what to do if a file ends. If the main difficulty is keeping a long broadcast running while your computer is switched off, StreamNeo removes the need to keep OBS running on your own computer for an uploaded video stream; it does not replace checking the content, YouTube preview or channel permissions. It is YouTube-only, so it is not a way to distribute the same stream to other platforms.
A practical run sheet for clip changes
A short run sheet turns the setup into a repeatable sequence. Write down the scene order, the clip expected in each scene, and any segment where audio or a specific transition needs attention. If you use hotkeys, include the shortcut beside the scene name and keep the sheet near the operator. Do not make the procedure depend on a memorised sequence of clicks that only one person knows.
Before going live, open OBS and inspect the starting scene. Confirm that it contains the right file, that the source is visible, and that the audio meter responds when the clip plays. Open the intended event in YouTube Studio, verify the preview and stream health, and protect the stream key from view. If you have changed a file path, scene, source property or transition since the last rehearsal, test that change again.
When the show is live, use one operating pattern consistently. With direct scene switching, select the next scene only when ready to put it on air. With Studio Mode, select and inspect it in preview first, then transition. For a VLC playlist, let the playlist behaviour govern progression and keep the operator informed about its order and loop setting. Mixing methods without a clear plan can make it harder to know which source controls the next item.
After the broadcast, note any point where the wrong scene appeared, a clip started unexpectedly, or audio needed adjustment. Correct the source or procedure and rehearse that exact case. A short record of what happened is more useful than assuming a setup that worked once will behave identically after files, settings or software have changed.

FAQ
Should I use a Media Source or VLC Video for two clips?
Use separate Media Sources in separate scenes if you want to choose either clip directly during the show. Use VLC Video when you want the files handled as a playlist and are comfortable installing VLC and managing playlist behaviour. The better fit depends on whether manual selection or sequence playback matters more.
Can I switch scenes without Studio Mode?
Yes. You can select a scene directly in OBS or assign a hotkey to switch to a specific scene. Without Studio Mode, the selected scene becomes the live output, so check the scene before you select it if an accidental change would disrupt the programme.
Does previewing a clip in Studio Mode mean it has played for viewers?
No. Studio Mode keeps a prepared scene in preview until you transition it to the live output. Check the source’s playback settings and rehearse the clip so you know how it starts when it becomes active.
Will switching scenes guarantee smooth, uninterrupted playback?
No. The result depends on the file, source settings and how the setup behaves during the broadcast; OBS scene switching is not a guarantee of uninterrupted playback. Test the full sequence, monitor YouTube’s preview and stream health, and have a known-good scene ready as a fallback.
