For one fireplace video, the simplest OBS setup is a dedicated scene with the clip added as a Media Source and Loop enabled. Check that the picture repeats cleanly, the crackling audio is present at a sensible level, and your stream can hold its chosen output settings before leaving it unattended.
A scene setting cannot guarantee nonstop playback. The goal is a simple setup that is easy to test and diagnose: use a Media Source for one local file, keep only the sources you need, and treat connection and computer load as separate things to monitor.
Create a dedicated fireplace scene
Open OBS and create a scene just for the fireplace stream. Give it a plain name such as “Fireplace loop” so you can identify it quickly if you use other scenes for announcements, a starting screen, or a different programme. Keeping this broadcast in its own scene makes it easier to check what is actually on air and reduces the chance that an unrelated source is visible by mistake.
In the Scenes panel, use the add control to make the new scene. Then use the Sources panel to add the video and, if needed, any separate audio source. OBS builds scenes by combining sources, so a single fireplace clip does not need a collection of decorative overlays. A clock, animated frame, browser widget, or extra video layer may be useful for a particular channel, but each one adds another thing to inspect if the picture or audio behaves unexpectedly.
Check the canvas before you go further. If the source is smaller than the output canvas, you may see empty space around it; if it is larger, parts of the image may be cropped. Use the transform controls to fit or position it deliberately, then look at the whole frame rather than judging only a close-up. A fire close-up can feel restful on a desktop and obscure important image detail on a phone, so consider how the composition looks at the size your viewers are likely to use.
The file itself also matters. Choose footage whose appearance can tolerate repetition: a sharp visual jump at the loop boundary can be noticeable even when playback is working as configured. Check the start and end of the clip before adding it, and listen to the transition as well as watching it. For more on planning the content around a repeated fire video, see how a crackling campfire stream can be made for meditation.
Add the clip as an OBS Media Source
With the dedicated scene selected, add a Media Source from the Sources panel and choose the local fireplace file. Give it a meaningful source name, such as “Fireplace video and audio”, especially if you may later add a separate audio source. Browse to the file rather than relying on a path you have not checked. If the source is missing later, a clear name and known file location make troubleshooting less of a guessing exercise.
For one local file, Media Source is the direct fit: it handles the media in the scene and provides a loop option. OBS lists playback controls and options for this source in its Media Sources guide. Available behaviour can depend on the source and how it is used, so check the controls in your installed OBS version rather than assuming that a setting from another person’s screenshot will match exactly.
After selecting the file, confirm that it appears on the preview canvas and that its audio is represented in the Audio Mixer if the file contains sound. Start playback in OBS and let the clip run through its end once during setup. This helps distinguish a valid file from a source that appears in the preview but does not play as expected. If the video has been moved since you added it, browse to its current location and confirm playback again.
There is no need to add a VLC Video source just because the clip must repeat. VLC is an alternative when you want playlist control; for one file, the built-in Media Source has the relevant loop function and avoids an additional dependency. Keep the scene understandable enough that someone checking it later can tell which source carries the picture and which carries the sound.
Enable Loop and review playback options
Select the Media Source and open its properties. Enable Loop, then test the transition from the end of the clip back to the beginning. Watch for a black flash, a pause, a sudden change in framing, or an audio cut that is jarring at the join. Loop tells OBS to repeat playback, but it does not make poor source transitions disappear or establish that every part of a long-running broadcast will remain available.
The Media Source properties include other playback choices, including restarting playback when the source becomes visible, hardware decoding when available, hiding the source when playback ends, and closing the file when it is inactive. These options affect source behaviour; they are not substitutes for checking the actual scene. For a dedicated scene that stays visible, restarting when visible may have little practical effect during normal playback, but it could matter if you switch away and back. Review what each option does in the current OBS interface and avoid changing settings without a reason.
If the source is set to hide at the end, test what happens with Loop enabled and disabled rather than assuming the combination behaves as you intend. Likewise, closing the file while inactive may be relevant if you switch scenes or manage media resources, but it is not a reason to make this one-source scene more complicated than necessary. The useful question is whether the chosen behaviour produces the picture and sound you expect when the scene is active, inactive, and active again.
Hardware decoding is another setting to approach as a test rather than a promise. It may be available for some media and systems; if playback becomes unstable after changing it, revert and compare. Keep a note of the settings that worked during an actual test, especially if another person may need to restart or inspect the stream.
A loop boundary is easier to assess if you watch several repetitions and listen on the speakers or headphones your viewers are likely to use. Check both the visible restart and the crackle: a smoothly looping image paired with a sharp audio splice can still be distracting. If the source file itself has a discontinuity, the remedy may be to choose or edit a better file rather than to search for another OBS checkbox.
Check the audio source and Mixer meters
Decide whether the fireplace sound comes from the video file or from a separate audio source. If the clip includes the crackling track, the Media Source may carry both picture and sound. If you want a different sound recording, add and name a separate audio source, then make sure you are not unintentionally hearing both versions at once. Overlapping crackle tracks can sound louder or phasey, even when each one seems acceptable on its own.
Look at the Audio Mixer while the scene plays. The intended source should show activity when the fire is audible. If there is no movement, check that the source is not muted, that the selected file actually contains audio, and that OBS is receiving it through the source you expect. If the meter moves but the stream has no sound, check the stream’s audio track and routing rather than assuming the visual meter proves the viewers can hear it.
Listen to the programme, not only to the meter. Crackling contains short peaks, so a setting that seems quiet at a glance may still sound abrupt or harsh. Keep the level steady and compare the loudest moments with the quiet passages. The right level depends on the recording and the intended viewing context; do not turn it up simply to make the Mixer look active.
Also check what happens at the loop point. If the crackling stops for a moment, clips abruptly, or jumps in loudness, listen to the source file around its beginning and end. If you have a separate audio source, verify that it loops as intended too. A picture repeating correctly does not confirm that the sound source is repeating correctly.
Choose output settings for your stream and machine
There is no universal OBS output preset for every fireplace stream. The workable combination depends on the platform’s current requirements, the source footage, the computer, and the stability of the upload connection. Set the output resolution to the target you actually plan to stream, and choose a frame rate the source and computer can sustain. OBS uses 30 and 60 frames per second as examples in its overview guide, which notes that 60 FPS can be more demanding than 30 FPS. For slow fire footage, decide whether the extra motion smoothness is visible enough to justify the additional load on your setup.
Bitrate is a trade-off between image detail and the capacity of the upload connection. OBS’s connection troubleshooting guidance gives 75% of total upload speed as a starting point for video bitrate and advises lowering it if dropped frames persist. Treat that as a diagnostic starting point, not as a guarantee or a platform limit. Upload performance can vary, and the usable bitrate must also fit the current requirements of the service receiving the stream.
| Choice | What you gain | What to check |
|---|---|---|
| 30 FPS rather than 60 FPS | Lower frame-rate demand on the system | Whether the fire motion still looks acceptable |
| Higher resolution or bitrate | More image detail when the connection can carry it | Upload stability, platform limits, and viewer buffering |
| Lower resolution or bitrate | Less demand on the upload connection | Whether the image still looks clear on common screens |
OBS’s overview gives around 160 kbps as a general audio-bitrate reference, while noting that lower values may suit limited upload. That is general guidance, not a requirement for every platform or a claim about the best setting for your clip. Check the current streaming service requirements before choosing audio and video output values, and test the stream at the settings you intend to use.
The Auto-Configuration Wizard can help establish a starting point by considering intended use, hardware, and network conditions. It cannot know whether your particular fire scene loops cleanly or whether viewers hear the crackling as intended. Use it as an initial configuration aid, then test the actual scene and stream rather than treating its recommendation as a final answer.
When a VLC Video playlist is useful
A VLC Video source is useful when you need a playlist rather than one repeating file. For example, you might want a sequence of different fireplace clips or several pieces of content to play in order. The documented VLC source behaviour includes a loop-playlist option, and the source requires VLC to be installed. Check OBS’s Media Sources documentation for the source distinction and the options available in your version.
For a single fireplace clip, VLC is not required. A Media Source with Loop enabled is the simpler choice because it avoids setting up a playlist when there is only one item to play. The difference is one of control and complexity: a playlist gives you a way to manage multiple files, while a single Media Source is straightforward for a single local file.
| Need | Better fit to consider | Trade-off |
|---|---|---|
| Repeat one local fireplace file | Media Source with Loop | Fewer moving parts; check the file and loop join |
| Play several local clips in sequence | VLC Video playlist | Playlist control, with VLC installation as a requirement |
Do not add a playlist just because the stream is intended to be long-running. A longer list can reduce how often one clip repeats, but it also creates more files and transitions to check. If you do use one, confirm the order, the playlist loop behaviour, and the picture and sound at every transition before making it part of the live scene.
Test the scene before leaving it unattended
Test the real configuration, not only the properties window. Start the scene, observe the image and audio, and allow the clip to reach its end and restart. OBS recommends testing settings and scenes before a first live stream in its overview guide. For a fireplace broadcast, that means checking the actual loop join, the intended Mixer source, and the stream output you plan to use.
If possible, watch the stream from a separate device or a viewer account. The preview in OBS confirms what OBS is composing; it does not alone confirm what arrives at YouTube or how it sounds after delivery. Confirm that the image is not cropped unexpectedly, the crackling is audible, and the viewer playback does not repeatedly buffer. If viewers report buffering while OBS shows no dropped frames, consider output resolution, frame rate, bitrate, and the viewer’s connection or device rather than assuming the scene itself is at fault.
Watch OBS’s dropped-frame counter during the test. OBS explains that dropped frames can point to an unstable connection to the ingest server or a bitrate the connection cannot sustain. If they persist, lower the bitrate and retest, while respecting the current service limits. A network speed test is only a moment in time; it cannot guarantee that the same upload performance will continue overnight.
Keep the scene lean and watch system load. OBS composites scenes using computer resources, so unnecessary browser overlays, extra media sources, or footage much larger than the output requires may add avoidable work. If you see encoding or rendering trouble, simplify the scene and test again; the OBS encoding and performance troubleshooting guide can help you separate computer-load symptoms from other problems.
For connection interruptions, configure Automatic Reconnect in OBS’s Advanced settings and check the reconnect delay and retry behaviour in the version you use. Reconnection can help OBS recover from some interruptions; it does not prevent every drop or prove that the broadcast will remain live continuously. If the stream repeatedly disconnects, investigate the connection and ingest path rather than assuming Loop is responsible. The checklist in how to diagnose a YouTube stream that disconnects every few minutes on Linux may help if that is your situation.
A practical handover note is useful if you will not be the person watching the stream. Record the scene name, the media file location, which source carries audio, and the output settings that passed your test. If a stream stops overnight, that information helps someone establish whether the file was moved, audio muted, scene changed, or connection lost. For a broader fault-finding path, see how to investigate a YouTube live stream that keeps stopping overnight.
If maintaining a computer and OBS session through a long run is the particular burden, StreamNeo turns an uploaded video into a YouTube live stream that can run with your computer switched off; you still need to prepare the file, connect the channel, and check the live result.

FAQ
Do I need VLC to loop one fireplace video in OBS?
No. Add the local file as a Media Source and enable Loop for a single clip. VLC Video is an alternative when you need playlist control, and it requires VLC to be installed.
Which OBS frame rate should I use for a fireplace stream?
Choose a frame rate your source and computer can sustain, then test how the fire looks in the delivered stream. OBS gives 30 and 60 FPS as examples and cautions that 60 FPS can be more demanding, so there is no single setting that suits every computer and source.
Why is the fireplace visible but the crackling is silent?
Check that the file includes audio or that your separate audio source is active, unmuted, and showing movement in the Audio Mixer. If the meter moves but viewers hear nothing, inspect stream audio track selection and routing, then test playback from a separate device.
Does enabling Loop keep a 24/7 stream running without interruption?
No setting guarantees uninterrupted playback or delivery. Loop repeats the media source; connection stability, computer load, source behaviour, and the streaming service remain separate considerations to test and monitor.
