When an encoder such as OBS is sending your programme to YouTube, change the visible video inside the encoder. Switch to another scene or source while leaving the encoder’s streaming session and the YouTube live event running.
Do not use Stop Streaming in the encoder or End Stream in YouTube Live Control Room for this job. Those controls stop the feed or conclude the event. A scene or source change alters what the encoder sends without making that an end-of-stream action.
What “change videos” means in an encoder stream
YouTube receives one encoded programme feed from your encoder. It does not normally choose between the local video files in that feed. Your encoder decides which picture is visible, which audio is included, and when the programme changes.
That distinction matters because “change the video” can describe several different jobs:
| What you want to do | Where you normally do it | What remains active |
|---|---|---|
| Move from one local video to another | Encoder scene or media source | The encoder output and YouTube event |
| Hide one source and show another | Encoder source visibility controls | The current live connection |
| Prepare the next video before showing it | Encoder preview and transition controls | The live programme until you transition |
| End the broadcast | Encoder Stop Streaming or YouTube End Stream | Nothing after the stream ends |
For example, a devotional channel might prepare one scene for a morning bhajan loop and another for an evening prayer loop. A study channel might use separate scenes for a lesson, a break screen and a revision playlist. The change happens in the production software, not by replacing the YouTube stream key or opening another YouTube video page.
YouTube’s encoder instructions describe sending a stream URL and stream key from the encoder, then taking the broadcast live in Live Control Room. The encoder is therefore the place to look when the goal is to change the programme picture.
This method applies when the new material is available to the encoder as a local file, media source, capture input or another supported production source. It does not establish a universal way to switch between arbitrary YouTube video pages inside an existing live event. If your material is hosted elsewhere, it must still be supplied to the encoder as part of the ongoing feed.
Prepare each video before you go live
The safest switch is prepared before the broadcast begins. In OBS, create a scene for each programme state you expect to use, then give the scenes names that are easy to identify while you are working quickly.
A practical set-up might include:
Morning BhajansAnnouncementsAfternoon LoopBreak ScreenEvening Aarti
In OBS, a scene is a layout made from sources. Add the relevant video as a Media Source in the scene that will use it. OBS documents support for common video file types including MP4, TS, MOV, FLV, MKV, AVI, GIF and WebM, with options such as looping and restarting playback when the source becomes active. Check the current OBS documentation and your installed version because menu labels can change.
Give the media source a clear name as well. Aarti_1900 is easier to recognise than Media Source 2, especially if you are operating a long broadcast on a small screen. If the video should begin from the start each time its scene becomes active, configure the source to restart playback when it becomes active. If it should continue from its previous position, use the setting that matches that behaviour instead.
Test the files before they become part of a live programme. Play each one from beginning to end, check that its picture fits the canvas, and listen for audio. A file that plays correctly in a media player can still need attention in the encoder because its source visibility, audio routing or playback behaviour may be different there.
If the files are unusually large or difficult for the encoder to play, deal with that before the broadcast. The guide on compressing video for streaming without visible quality loss explains why a smaller, well-prepared file can be easier to operate than an unnecessarily heavy one. Compression is not required merely to switch scenes, but it can reduce avoidable playback problems.
Switch scenes or video sources in OBS
There are two straightforward ways to change the visible programme in OBS.
Switch to a prepared scene
If each video has its own scene, select the destination scene while the stream is live. OBS changes the programme output to that scene. You can use a direct cut, or configure a transition such as Fade if you want the change to be less abrupt.
For a simple channel, a direct switch may be enough. For a worship service, local news loop or station ident, a short fade may make the change look more deliberate. The important control is the scene change itself. The transition changes how the picture moves from one scene to the next; it does not end the YouTube event.
OBS Studio Mode gives you a preview area and a programme area. Prepare the next scene in preview, confirm that it is the one you intend to show, then use the transition control to put it on air. This is useful when an operator needs to check the next video without exposing the wrong scene to viewers.
Show one source and hide another
You do not need a separate scene for every change. A single scene can contain several video sources. In the Sources list, show the source you want and hide the source that should no longer be visible. The order of sources controls which visible item appears above another.
This approach can work well for a fixed layout. For instance, a local news loop might keep a logo and lower-third graphic in the scene while changing only the video source behind them. It also gives you a way to retain a common background or overlay while replacing the main programme.
Take care with source audio. Hiding a picture source and showing another does not automatically mean the audio mix now matches the visible picture. Watch the audio mixer while you make the change, and mute or unmute sources deliberately rather than assuming the encoder will infer your intention.
The OBS Studio overview explains scenes, sources, Studio Mode and transitions. Its Media Sources guide covers the relevant playback options and supported media behaviour.
Keep the encoder and YouTube event running
Once the live programme is active, the critical operational rule is simple: change the source, not the connection.
Leave OBS connected and streaming. Leave the YouTube event open in Live Control Room. Select or transition to the next scene inside OBS, then allow a moment for the new picture to appear in the encoder’s programme output and in YouTube’s preview.
YouTube’s own wording is useful here: to end a stream, you stop sending content from the encoder. That is a different operation from changing the scene that is being encoded. Pressing Stop Streaming because you want a different video turns a programme change into a connection-ending action.
Do not change or reset the stream key as part of a normal scene switch. The stream key tells YouTube where the encoder sends its feed. It is relevant when you are configuring or troubleshooting the connection, not when you are choosing which prepared source is visible.
You can read more about the boundary between production controls and YouTube’s event controls in this guide to what YouTube Live Control Room can and cannot automate. Live Control Room manages the YouTube side of the broadcast, while the encoder remains responsible for constructing the programme that YouTube receives.
If you run a 24/7 channel and do not want a personal computer left on to handle every change, StreamNeo removes that particular operating task by running an uploaded video as a YouTube live stream and allowing you to supply the stream key once. It is YouTube-only, so the same scene-switching question still belongs to whichever production workflow creates the programme file you send.
A scene switch can still coincide with a brief visual change if the file takes time to start or the encoder is under load. Keeping the session active avoids deliberately ending the broadcast, but it cannot make every source change invisible in every setup. Test the exact files and transitions you plan to use.
Check the preview and audio after switching
Do not stop at the moment you click the new scene. Confirm what viewers are receiving.
First, look at the encoder’s programme output. Is the new picture visible, or are you still seeing the old source, a blank canvas or a frozen frame? If you use Studio Mode, check that you transitioned the preview scene rather than merely preparing it.
Second, check YouTube’s live preview. The preview may take a short time to reflect the new content, so avoid making repeated changes before you know which one has arrived. If your channel has a separate monitoring device or viewer account, use it as an additional check, but do not treat a delayed preview alone as proof that the switch failed.
Third, listen for the new video’s audio. A visible video can be silent because its audio source is not active, has been muted, is routed to the wrong monitoring path or is not included in the stream mix. Check the OBS audio mixer and the source’s audio properties.
Picture and audio are separate paths. YouTube’s guidance about its video away-slate feature gives a useful example: changing the displayed video does not automatically change the audio sources. The same principle applies when you switch media in an encoder. Confirm both elements independently.
Use this quick check immediately after each change:
- The intended scene or source is selected.
- The new picture is visible in the encoder programme output.
- YouTube’s preview shows the intended programme.
- The expected audio meter is moving.
- A listener can hear the new video rather than the previous source.
- The encoder still indicates that it is streaming.
If your stream contains announcements or a channel ident, leave enough time to verify them before switching again. Rapid troubleshooting clicks can make it difficult to tell whether the problem is the source, the transition, the preview delay or the audio mix.
If the new video does not appear
Start with the encoder rather than changing YouTube settings. A source may be hidden, underneath another source, outside the canvas or assigned to a scene that was prepared but never put on air. Check the scene name, source visibility and source order.
If the scene is correct but the picture is blank, inspect the media source. Confirm that the file path still exists, that the file opens locally, and that the source is set to play in the way you expect. If the source was moved or renamed after you created the scene, OBS may no longer be able to load it.
If the old video remains visible, look for a second source covering the new one. In a layered scene, a still image, browser source or other media source can sit above the source you intended to show. Hide the covering source temporarily or adjust the source order, then check the programme output again.
If the new picture appears but there is no sound, check the source’s audio routing and the encoder mixer. Make sure the correct source is not muted and that another source has not been left active at the same time. A source can be visible while its audio is absent, and a source can be audible after its picture has been hidden.
If OBS stops sending altogether, check whether Stop Streaming was pressed accidentally and whether the encoder still has the correct stream URL and key. YouTube’s live-stream troubleshooting guidance recommends checking the stream key in Live Control Room and updating the encoder with the current key when there is a connection problem.
If you ended the event rather than merely switching the source, do not assume that the same concluded event can resume unchanged. Follow the current controls in YouTube and your encoder for reconnecting or creating another broadcast. The safer habit is to keep your hands away from the end controls when the actual task is only to change the programme.
If you are switching between horizontal and vertical formats, plan that before going live. YouTube’s live-streaming getting-started guidance states that vertical format cannot be added after the stream has started. A scene change is not a substitute for a format configuration that must be made before the event.
Choose a switching method that suits the channel
There is no single best arrangement for every always-on channel. Choose based on how often the programme changes, who operates it and whether the next item needs to be checked before it reaches viewers.
| Method | Useful when | Main trade-off |
|---|---|---|
| Separate scene for each video | The operator needs clear, named programme states | More scenes to organise and test |
| Several sources in one scene | The layout stays the same while the main video changes | Visibility and audio must be managed carefully |
| Studio Mode with a transition | The operator needs to preview the next item | It adds a preview-to-programme step |
| A prepared playlist or automated sequence | The channel follows a repeatable schedule | The playback and failure behaviour needs testing |
For a non-technical operator, named scenes are often easier to understand than a crowded source list. For a small business that changes between a product loop and an announcement, one layout with controlled source visibility may be simpler. For a devotional channel with planned morning and evening blocks, separate scenes can make the intended state clearer.
Whatever method you choose, test the complete change rather than only testing each file. Start with video A, switch to video B, verify the picture and audio, then switch back. Test the beginning of each file and what happens when it reaches its end. If a video should loop, confirm that the loop behaves as expected rather than leaving a blank frame or an unexpected stop.
An always-on channel also needs a plan for interruptions around the change. Keep a neutral break screen or announcement scene ready if the next source fails to load. That does not guarantee an uninterrupted broadcast, but it gives the operator a known visual state while investigating the source.
Review the result after the broadcast as well. Reading analytics when the stream never ends can help you compare what happened around a programme change with viewer behaviour, but analytics will not tell you every source or audio mistake. Keep a simple log of the scene, time and observed result so that the next switch is based on your own channel’s evidence.

FAQ
Can I change videos in YouTube Live Control Room itself?
The documented encoder workflow places the programme production in the encoder. To change a local video during the broadcast, switch the scene or source in the encoder while keeping the YouTube event and encoder session active.
Will viewers see a pause when I switch scenes?
A prepared cut or transition can change the programme cleanly, but no encoder setup can guarantee that every source change will be invisible. File loading, source configuration and encoder load can affect what viewers see, so test the exact switch before relying on it overnight.
Why is the new video visible but silent?
The source’s picture and audio may be routed separately. Check its audio settings, the encoder mixer and whether the source is muted or excluded from the stream mix.
Should I change the stream key when changing videos?
No. A stream key identifies where the encoder sends its feed; it is not a control for selecting the visible video. Use the key when configuring or troubleshooting the connection, not as part of a normal scene or source change.
