OBS Studio supports Lua and Python scripts, and a script can react to a media file ending by switching the program output to another scene. That behavior is not a built-in one-click OBS control: you need a suitable script, correctly configured sources and scenes, and a full test before relying on it live. A community example called Media Switch Scene was last updated in 2021 and also requires Audio Status Monitor, so check compatibility with your installed OBS version.
What automatic switching in OBS actually involves
There are two separate jobs: playing a video and changing the scene shown in the stream. An OBS Media Source plays a local media file; a script can watch for the end of playback and tell OBS to transition to a scene containing the next video. The transition is what changes the program output, rather than the file ending by itself.
OBS includes a scripting interface under Tools > Scripts. Its documentation for OBS Studio 33.0.0 describes support for LuaJIT 2 and Python 3. OBS says scripts can extend or automate the program without building a native plugin. The interface is built in, but the particular automation you want still depends on a script and its setup.
Choose a playback source and a trigger
Media Source or VLC Video
| Source | Useful when | Considerations |
|---|---|---|
| Media Source | You want OBS to play a local video or audio file with playback properties such as looping. | Configure the file and playback behavior in the source, then make sure the script watches the intended source. |
| VLC Video | You want to use VLC-based playlist playback. | VLC must be installed. The OBS guidance specifies 64-bit VLC when using 64-bit OBS. |
OBS documents these source types in its Media Sources guide. Pick one based on whether you need a single file or playlist handling; do not assume a script for one source type will control the other without configuration changes.

Match the trigger to the sequence
- Playback-ended event: appropriate for advancing when a clip finishes. The community Media Switch Scene example is designed around this behavior.
- Timer or schedule: can be suitable when changes should happen at fixed intervals, but the duration may not match the actual playback if a file stalls or ends early.
- Hotkey or external event: useful when a person or another system should decide when to change scenes; it requires a different trigger implementation.
OBS scripting supports callbacks and timers, but there is no single official ready-made script established for every switching pattern. Choose a script that explicitly supports the trigger and source setup you intend to use.
Set up a video-ended scene switch
- Build the scenes: in OBS, create a scene for each video or playback state you need. Add the appropriate Media Source or VLC Video source, select the file or playlist, and check its playback properties. Give sources and scenes clear names so you can identify them accurately in script settings.
- Decide what happens at the end: choose whether the script should switch to a scene containing the next clip, return to a holding scene, or follow another defined sequence. A source reaching its end does not itself specify the next scene.
- Find a script designed for that source and behavior: Media Switch Scene is a community example for changing scenes after a selected media file ends. Its forum page says Audio Status Monitor is also required, and lists its last update as December 20, 2021. Confirm that both the script and dependency work with your OBS release and operating system before using them on a live channel.
- Load and configure the script: open Tools > Scripts, add the script file, and use its properties to select the watched source and destination scene or other required settings. Install and load any stated dependencies. Exact property names and setup vary by script; verify that the names match the sources and scenes in your OBS project.
- Choose Lua or Python based on the script: LuaJIT is embedded in OBS. On Windows or macOS, a Python script requires a compatible Python installation and a Python path configured in OBS; the Python architecture must match OBS. Follow the current OBS Python/Lua Scripting documentation for setup rather than assuming Python is ready automatically.
- Test the whole sequence: start playback, let the clip reach its actual end, and verify the intended scene becomes active. Check video, audio, transition timing, repeated cycles, and what happens if playback is stopped or restarted. Then test the output in YouTube’s preview before making the stream public.
If you write or modify a script, OBS warns that poorly written scripts can crash the application or leak memory. Its scripting API is close to the OBS C API; handle object references carefully and release references to objects that the script acquires or creates.

Connect OBS to YouTube separately
Scene automation does not configure stream delivery. In YouTube Studio, create or select a live stream and use the encoder connection details to configure OBS with YouTube’s stream URL and stream key. Treat the key like a password: do not show it in a recording, screenshot, or public post. See YouTube’s live stream settings guidance for managing stream settings.
First-time live-stream enablement can take up to 24 hours, according to YouTube’s encoder setup guidance. Allow time for this before a scheduled event. YouTube recommends testing before starting and monitoring stream health and messages while live.

Encoder settings to check
| Setting | YouTube guidance | What it means for OBS |
|---|---|---|
| Video codec | H.264, H.265/HEVC, or AV1 for RTMP/RTMPS workflows. | Choose a codec supported by your encoder workflow and hardware. |
| Frame rate | Up to 60 fps. | Set a frame rate appropriate to your video and available upload capacity. |
| Keyframe interval | 2 seconds recommended; do not exceed 4 seconds. | Set the encoder’s keyframe interval accordingly. |
| Rate control | CBR. | Use constant bitrate encoding. |
| Audio | AAC or MP3. | Check that the selected audio encoder and track are active. |
These are encoder recommendations, not script requirements. The appropriate bitrate depends on resolution, frame rate, codec, and the upload capacity of your connection; use YouTube’s encoder settings, bitrates, and resolutions guidance for the stream format you choose.
Test before scheduling a public stream
YouTube advises setting up an encoder at least two hours before an event and running it at least 15 minutes before the scheduled start. Its streaming guidance also recommends leaving upload-bandwidth headroom, including a 20% recommendation. These are platform recommendations, not guarantees that a particular connection or setup will be stable.

- Please Note: To reach 10Gbps speed, keep the cable under 3.3 ft. For USB A Male to USB C adapters, try flipping the USB C connector. USB C Male to USB A adapters support bidirectional 10Gbps transfer within 3.3 ft
- Run the video sequence locally in OBS and observe every intended playback-ended transition.
- Start an unlisted or private test stream where appropriate, then inspect the Live Control Room preview and stream-health messages.
- Check that audio continues across scene changes and that each source behaves as expected after a restart or a manually stopped clip.
- Confirm the stream key, encoder output, and selected destination before starting the public event.
Troubleshooting common switching problems
- The video ends but the scene does not change: confirm that the script is loaded under Tools > Scripts, that its watched source name matches the actual source, and that its destination scene exists. Verify any required dependency is installed and active.
- The wrong scene appears: recheck the script’s scene selection and the OBS scene names. Confirm the script is watching the intended media source rather than a similarly named source in another scene.
- It switches too early or not at all: test with a short clip and observe how the script handles stopped, restarted, or looping playback. A timer-based trigger and a playback-ended trigger are not interchangeable.
- VLC playlist playback is unavailable: verify VLC is installed and that its architecture matches OBS; OBS specifically calls for 64-bit VLC with 64-bit OBS.
- A Python script does not load: check that Python is installed, matches OBS architecture, and its path is configured in OBS. If the chosen script supports Lua, LuaJIT is embedded and does not require a separate Lua installation.
- OBS crashes or becomes unstable: remove or disable the script to determine whether the issue is related, then review the script’s compatibility and object-reference handling. Do not depend on an unverified community script for a scheduled stream.
- OBS switches locally but YouTube has no picture or audio: troubleshoot encoder output separately from scene automation. Check the stream URL and key, codec and audio settings, upload headroom, and YouTube’s stream-health messages.
