For a 24/7 YouTube stream, neither OBS Studio nor FFmpeg has a clear software-licence cost advantage: both are available as open-source software without a paid licence fee being the deciding line item. Which setup costs less overall depends on your host, measured electricity use, internet plan, reliability arrangements and the time you spend setting it up and keeping it running.
There is no universal cost winner, and the available documentation does not establish that FFmpeg inherently draws less power than OBS. To compare them fairly, run the same stream on the same host, measure whole-system power, and count the labour and recovery work as well as the electricity.
Licence cost is not operating cost
OBS Studio is free to use, including commercially, under the terms described on the OBS Help Portal; the project is open source under GPLv2-or-later. FFmpeg is an open-source multimedia framework. Its official documentation describes tools for reading, filtering, encoding and outputting media. Neither description makes a paid software licence the deciding cost for a typical comparison.
That does not mean a 24/7 stream costs nothing. The application is one part of a running system. A computer left on all month draws electricity; a cloud host incurs a hosting charge; a fixed playlist may need setup and monitoring; and a dropped stream can cost time to diagnose and recover. A free application can sit inside an expensive operating arrangement, just as a paid service may replace some of your own setup and maintenance work.
Keep the accounting categories separate. A licence comparison asks what permission to use the software costs. An operating comparison asks what you must pay or contribute to keep the channel broadcasting reliably. Mixing them can make a setup look cheaper simply because its largest costs are being left out.
For a solo devotional channel using an existing desktop, the purchase price may already be sunk. For a small business deciding whether to buy a dedicated always-on computer, the host purchase and its useful life matter. Neither case can be settled by comparing the applications’ licence descriptions alone.
What determines the complete monthly cost
A useful model is: host amortisation or hosting charge, plus electricity, any incremental internet charge, backup or reliability costs, and operator time. Not every channel has each item, and the amounts vary by location and workload. Record which costs are genuinely incremental: if you already pay for an internet plan that supports the stream, the whole bill is not automatically a new streaming cost.
For owned hardware, estimate electricity from measured wall power rather than a processor-usage percentage. The calculation is average measured watts divided by 1,000, multiplied by 24 hours, then by 30.4 days, then by your local electricity price per kilowatt-hour. The 30.4-day figure is an averaging convention for a monthly estimate, not a claim about your bill. Your actual billing period, tariff and consumption tiers may differ.
If you already own a suitable host, its original purchase price is generally not part of the marginal cost of choosing OBS over FFmpeg. Its extra power use, wear, and the opportunity cost of keeping it occupied can still matter. If you need to buy equipment, account for purchase cost over the period you expect to use it, along with compatibility and power measurements. A mini PC with a documented hardware encoder may be a category worth researching, but without a specific model and measured workload it cannot be called the cheapest choice.
For a cloud host, compare a machine capable of your chosen codec and workload across roughly 730 hours in a 30.4-day month, then add any applicable network egress or service charges. These are evaluation quantities, not current provider prices. Check the provider’s own pricing and limits before committing; an inexpensive virtual machine that cannot encode or sustain the stream you need is not a like-for-like option.
Internet cost depends on your ISP, location and plan. YouTube’s published bitrate recommendations help you size a sustained upload, but they do not tell you what your ISP charges or whether your connection is stable. As an example of the setting to plan around, YouTube recommends 5 Mbps for H.264 at 1080p30 and 6 Mbps at 1080p60. Check the current YouTube encoder settings for your intended resolution, frame rate and codec, then leave practical upload headroom for other household or business use.
Hold the streaming setup constant
A comparison only tells you something about OBS versus FFmpeg if you keep the work as similar as possible. Use the same media source, resolution, frame rate, bitrate, codec, encoder, audio settings and host. Keep other running processes unchanged. If one test uses a hardware encoder and the other uses software encoding, you are comparing two configurations, not just two applications.
That distinction matters because both programs expose choices that affect workload. OBS can compose scenes and capture sources; FFmpeg can read, filter and output media through command-line tools. The source can be a static image, a changing video loop, a browser capture, or a scene with transitions and overlays. Decoding, compositing, encoding and audio processing all contribute to what the machine is doing.
YouTube recommends testing representative audio and motion while watching stream health. Use the actual overnight playlist or scene rather than an idle desktop or a short, unusually simple clip. If your channel uses a slow devotional loop with a moving background, test that. If it has a local news ticker, capture card or changing camera source, include those elements too.
The 1080p 30fps settings guide can help you settle the intended output before measuring. For a fixed recorded playlist, the walkthrough on setting up an overnight stream with recorded videos is also relevant: settle the playback design first, then compare the two ways of producing it.
Write down the exact configuration and the start and end conditions. Confirm that the stream reaches YouTube, that audio is present, and that the health indicator remains acceptable. If you change an encoder preset or frame rate midway through, label that run as a different test rather than treating it as evidence about the application alone.
Measure wall power on the same host
Use a plug-in wall meter or a trustworthy whole-system measurement that captures the host’s input power. Measure the same computer first with one configuration, then with the other, while each runs the representative stream. Avoid changing the monitor, peripherals, network equipment or background workload between runs unless those changes are part of the actual setup you are comparing.
Record average power over representative periods, not a momentary reading during startup. Include the normal idle state, playback, encoding and any routine scene activity. If a test period does not represent the overnight load—for example, the playlist has not yet reached its animated segment—extend or repeat it. The result belongs to the setup and workload tested; it is not a general property of OBS or FFmpeg.
CPU utilisation alone cannot answer the electricity question. A GPU encoder may shift work away from the CPU; decoding and compositing may add work elsewhere. OBS documents hardware encoder support such as NVIDIA NVENC, AMD AMF, Intel Quick Sync and Apple VideoToolbox, subject to platform and hardware qualifications. Its hardware encoding guidance explains that hardware encoders move encoding work to a specialised component. That is an explanation of workload, not proof of lower whole-system power or a cost advantage over FFmpeg.
Use the same encoder where both applications support it on your hardware, and verify that the output settings match. If the chosen encoder is unavailable or behaves differently in one program, report that honestly: you have found a compatibility or workflow difference, not a controlled power comparison. In either case, measure wall power rather than inferring energy use from a task manager graph.
You can turn each average wall-power reading into an electricity estimate using your local tariff and the formula above. Keep the raw watt reading, meter method, workload and tariff alongside the estimate. That makes the comparison useful later if your scene changes or your electricity rate changes, without pretending the result applies to another channel.
Include hosting, electricity and labour
The table below shows what to record. It deliberately leaves prices and watts to your own setup: the available research does not establish a representative monthly total, current provider prices or local electricity rates.
| Cost or constraint | Owned host | Cloud host | What to compare |
|---|---|---|---|
| Host | Purchase cost if buying new; existing machine may be sunk | Monthly instance or hosting charge | Can it run the actual encoder and workload? |
| Electricity | Measured whole-system draw and local tariff | Usually included in the service charge, but verify terms | Avoid counting electricity twice or assuming it is free |
| Internet and egress | ISP plan and any incremental charge | Hosting egress or network limits, plus viewer-side platform delivery | Check sustained upload and applicable data charges |
| Reliability | Power, network and hardware recovery arrangements | Provider terms and your recovery procedure | Include what you actually need to keep the channel operating |
| Operator time | Setup, monitoring, troubleshooting and updates | Configuration, monitoring and troubleshooting still remain | Record recurring effort as well as initial setup |
For an owned host, calculate the stream’s incremental electricity from the wall-power readings. If you are buying hardware, compare the purchase and expected useful life against hosting alternatives. Do not select a machine because a processor label suggests it is efficient; check its encoder compatibility and measure the complete system running your real stream.
For cloud hosting, compare the full month rather than a short test session. Estimate the time the instance must run, then verify the vendor’s current instance price, storage, egress and service limits on its own site. Do not assume that a low hourly compute charge represents the whole bill. Conversely, a cloud setup may suit you better if you do not want to keep a local computer and connection available overnight.
Time is a real operating input even if it never appears on a utility bill. OBS may be easier to operate for someone who needs graphical scene controls, capture sources and transitions. A fixed FFmpeg command may suit someone comfortable maintaining a scripted playlist. Either workflow could take more or less time depending on the person, the channel and how often content changes.
If your stream is a scripted playlist on a VPS, the guide to limiting FFmpeg CPU use on a VPS may help you understand the configuration side. It is not a substitute for measuring power or checking that the stream remains healthy; a CPU limit can change whether the workload completes properly.
Account for failures, restarts and archives
A cost comparison that counts a clean run but ignores drops is incomplete. Note interruptions, how long each configuration takes to recover, whether it restarts automatically, and how much operator attention is needed. If a stream stops at 3 am and you must reconnect it manually, that is a practical cost even if the electricity estimate is low. Test your recovery procedure deliberately, where safe, rather than assuming a process will restart correctly because it launched once.
Separate application recovery from connection and hardware failures. A rebooting machine, lost internet connection or expired stream session can interrupt either application. Record what actually happened during the test and what support or monitoring you would need in routine operation. Avoid translating a short successful test into an uptime promise.
Archive needs also affect operations. YouTube says streams shorter than 12 hours are automatically archived. A single uninterrupted 24-hour broadcast is longer than that threshold, so do not assume it will be fully archived automatically. If keeping complete recordings matters, plan how you will segment sessions or record and retain the source separately, then account for the storage and operator steps involved.
For a channel that depends on viewers finding an active broadcast, include a way to check whether it is still live and who is responsible for intervening. The practical checks in how to tell whether a 24/7 stream is still live can inform that routine. Apply the principle to your own channel rather than assuming any particular monitoring approach guarantees continuity.
Choose on the complete setup
OBS can be the more natural operational fit when you build scenes, use capture sources, manage transitions or prefer graphical controls. FFmpeg can be a direct fit for a fixed playlist or loop that you are comfortable defining and maintaining with commands. Those are workflow distinctions, not cost verdicts. If you need frequent visual changes, ease of operation may be worth more than a small difference in measured electricity; if the stream never changes, a simple scripted workflow may reduce routine interaction for you.
Compare two actual configurations on six axes: measured wall power, host purchase or hosting charge, encoder and codec compatibility, sustained upload and any usage charges, recovery and maintenance effort, and archive/session handling. Keep the test conditions alongside the result. If the two runs used different machines, say that the comparison is between systems rather than attributing the difference to OBS or FFmpeg.
For your own decision, put the evidence in a small worksheet: configuration, output settings, average wall watts, estimated monthly electricity at your tariff, host cost, internet or egress increment, failure/restart notes and time spent. Leave unknowns marked as unknown until you can verify them. A realistic comparison with one missing price is more useful than a precise-looking total built from invented assumptions.
If you already have a capable computer and want to operate it yourself, include the incremental power and the time you will spend maintaining it. If you would rather not leave your own computer on and manage restarts, StreamNeo removes that specific always-on computer and restart-maintenance task by turning an uploaded video into a YouTube stream that runs while your computer is off. It does not settle OBS-versus-FFmpeg power use on your host, and it is YouTube-only, so compare the operating arrangement you actually need.
Before committing, compare the operating options on the pricing page. When the file and channel are ready, start free — 24-hour trial, no card.
FAQ
Is FFmpeg cheaper than OBS for a 24/7 stream?
Neither has a clear paid-licence advantage in the sources reviewed, and no universal total-cost winner follows from that. Compare the host, measured power, internet or hosting charges, reliability arrangements and your time on the actual workload.
Does FFmpeg use less electricity than OBS?
There is no established general rule that it does. Measure whole-system wall power on the same host with matched source, output settings, encoder and background processes; CPU utilisation by itself is not an electricity measurement.
Should I use OBS or FFmpeg for a recorded-video loop?
For a fixed playlist that you are comfortable scripting, FFmpeg can be a straightforward workflow. OBS may suit you better if you need graphical controls, scenes, capture sources or transitions; test the maintenance and recovery work as well as the initial setup.
Will a 24-hour YouTube stream be archived automatically?
YouTube’s help guidance says streams under 12 hours are automatically archived, so a single uninterrupted 24-hour broadcast exceeds that stated duration. If complete archives matter, plan session segmentation or separate recording and check YouTube’s current guidance.
