The main way to reduce data usage in an OBS 24/7 YouTube stream is to reduce the total bitrate being sent. Start with the bitrate OBS actually sends, then lower video bitrate, resolution, or frame rate only after checking how your real content looks.
There is no single data quota or accounting rule that applies across India. Use the calculation below as an estimate, then compare it with your own broadband, fibre, mobile, or router plan and its usage meter.
What determines an OBS stream’s data use?
A continuous stream sends data for every second that OBS is connected. The most important setting is total outgoing bitrate, made up mainly of video and audio. If OBS sends 3 Mbps for a long period, it sends less data than if it sends 6 Mbps for the same period, although the lower setting may show more compression.
Video normally makes up most of the stream. Audio is smaller, but it still contributes to the total. YouTube’s live encoder guidance recommends 128 Kbps for stereo audio, so audio should be included when you estimate the complete stream rather than looking only at the video bitrate. See YouTube’s current live encoder settings and bitrate guidance before publishing, because platform recommendations can change.
Your outgoing data can also differ from the number you typed into OBS. The actual amount is affected by the measured output, changes in the encoded stream, protocol overhead, reconnects, and other traffic using the same connection. A stream set to a particular video bitrate is therefore a useful planning basis, not a precise promise about the number shown on your provider’s bill.
Resolution and frame rate matter because they affect the picture the encoder has to represent. A 1080p scene with fast movement and fine detail usually places different demands on the encoder from a mostly static devotional image or a text-based information display. Lowering resolution or frame rate can make a lower bitrate more workable, but it does not preserve identical picture quality by itself.
The computer’s other internet activity matters as well. Cloud backups, software downloads, security updates, another OBS output, and viewers using the same connection can all add traffic. They may not be part of the YouTube stream, but they can affect available upload capacity and make the stream less stable.
YouTube transcodes a live stream into different playback formats for viewers and network conditions. That gives viewers playback choices, but it does not reduce the source data OBS has already uploaded. Reducing the source upload requires changing what OBS sends.
Estimate usage from the bitrate actually sent
For a first estimate, use this conversion for decimal gigabytes:
GB per 24 hours ≈ total outgoing Mbps × 10.8
The calculation converts megabits per second into bytes over 86,400 seconds. It is arithmetic based on the bitrate, not a published usage statistic from YouTube or an Indian provider.
| Approximate total outgoing bitrate | Estimated data for 24 hours |
|---|---|
| 1 Mbps | 10.8 decimal GB |
| 2 Mbps | 21.6 decimal GB |
| 3 Mbps | 32.4 decimal GB |
| 6 Mbps | 64.8 decimal GB |
| 8 Mbps | 86.4 decimal GB |
These figures assume that the stated bitrate represents the whole stream and remains continuous. If your OBS setting is video-only, add the audio bitrate first. At 128 Kbps, stereo audio adds approximately 1.38 decimal GB over 24 hours by the same calculation. Actual usage can be higher or lower because of overhead, changes in output, reconnections, and unrelated traffic.
For a shorter period, multiply the total Mbps by 10.8 and then multiply by the fraction of a day. For example, a stream operating for twelve hours uses roughly half the 24-hour estimate under the same assumptions. For a monthly estimate, multiply the daily estimate by the number of streaming days, but do not treat that result as the amount your provider will necessarily count.
Decimal GB and GiB are not the same unit. A provider may display one or the other, round usage differently, or include other traffic from the connection. Some plans may have a fixed allowance, while others may have fair-use terms, separate mobile tethering treatment, or no practical monthly data cap. Do not infer the rule from a neighbour’s plan or from an old offer.
The useful number to record is the actual outgoing bitrate during a representative period. In OBS, open the Stats window while the intended scene is running and note the stream bitrate, dropped frames, and connection behaviour. You can also compare the router or provider usage meter before and after a controlled test, provided no other device is generating significant traffic.
This is more useful than calculating from a target setting that OBS cannot sustain. If you entered a value but the connection repeatedly reconnects, the actual session may include bursts and interruptions that your simple estimate does not describe.
Choose a sustainable starting point
Before reducing anything, test the upload connection at the time and location where the channel will operate. YouTube recommends running a speed test to test your upload bitrate, and the result should be treated as a guide rather than spare capacity that can all be assigned to OBS.
A 24/7 stream needs headroom for normal variation. If the stream consumes almost all of the available upload capacity, a small change on the line can cause dropped frames or buffering. Other household traffic can also compete with OBS. A lower, steady bitrate is often more useful than a higher setting that works only when the connection is quiet.
Use the content you intend to stream when choosing a baseline. A still image with gentle audio is not a good test for a music visualiser, scrolling ticker, camera feed, or footage with quick cuts. Test a section with the most motion and the smallest text that viewers must read.
YouTube’s current live guidance lists codec-specific recommendations. For H.264, it gives a recommended range of 3–8 Mbps for 720p at 30 or 60 frames per second, 5–14 Mbps for 1080p at 30 fps, and 6–17 Mbps for 1080p at 60 fps. The same page lists different recommended values and minimums for AV1 and H.265. These are ingestion recommendations, not guarantees that every scene will look acceptable at every value.
Use the recommendation for the codec and output format selected in OBS. YouTube also specifies constant bitrate and recommends a two-second keyframe interval, not exceeding four seconds. Confirm the current table before you publish rather than relying on a saved screenshot or an older tutorial.
Reduce video bitrate carefully
In OBS, go to Settings, then Output, and locate the video bitrate field. Reduce it in a controlled step, apply the change, and watch both the picture and the connection. The purpose is not to reach the smallest possible number. It is to find the lowest setting that remains useful for your particular scene and stable on your connection.
Reducing video bitrate generally reduces outgoing data, but it also gives the encoder fewer bits with which to describe the image. Areas with movement, smoke, water, grass, confetti, patterned fabric, and fine text can show blockiness or smearing first. A static background may appear acceptable while a scrolling news strip becomes difficult to read.
Do not judge the result from the scene when it is paused. Let the loop pass through its busiest section. Watch a local preview and, where possible, check the YouTube playback from another device or connection. YouTube’s delivered playback may be at a different resolution from the source, so record what you changed and assess the source and viewer experience separately.
The reduction should be paired with a check for dropped frames. If frames are being dropped because the connection cannot upload reliably, lowering the video bitrate may help. If the problem is Wi-Fi interference, an overloaded router, or an unstable line, bitrate reduction may not remove the underlying cause.
OBS includes a setting to dynamically change bitrate to manage congestion. It can reduce the bitrate when the network cannot keep up, which may help prevent some dropped frames, but OBS notes that this lowers video quality and does not fix an unreliable connection. Treat it as a response to congestion, not as a replacement for diagnosing the line and choosing a sustainable baseline. The OBS stream connection troubleshooting guide explains this trade-off.
Audio should not be the first place you make a large saving. A suitable stereo audio setting is a small part of the total compared with several megabits per second of video, and reducing it can be noticeable in devotional music, bhajans, ambient tracks, or spoken news. Keep the audio appropriate to the material, then concentrate on the larger video component.
Lower resolution or frame rate when suitable
If lowering bitrate makes the picture too soft, consider reducing the output resolution. In OBS, the scaled output resolution controls the resolution sent to YouTube rather than the size of the source canvas used to arrange scenes. A smaller output can reduce the amount of fine detail that must be encoded and may make a lower bitrate practical.
This is most suitable when the content does not depend on small text or detailed movement. A devotional loop with a large central image may remain useful at a lower output resolution. A local news loop with a ticker, map labels, or emergency information may need enough resolution for text to remain legible. Check the smallest important element, not only the large background.
Frame rate is another setting to consider. A lower frame rate sends fewer frames to encode over time, which may suit a mostly static slide, a slow ambience scene, or a simple information display. Fast camera movement, dance footage, sports, or rapidly changing visualisers may look less smooth when frame rate is reduced.
Resolution and frame rate are not independent of bitrate. A 1080p, 60 fps output generally needs a different balance from a 720p, 30 fps output. YouTube’s table groups recommendations by resolution and frame rate for that reason. Do not select a value only because it is labelled HD; use the profile that matches what viewers need to see.
Change one main variable at a time. If you reduce resolution, frame rate, and bitrate together, you may save data but will not know which change created the improvement or the loss in quality. Keep a short record such as “720p, 30 fps, video bitrate X, audio bitrate Y”, then compare it with the previous profile.
A wired Ethernet connection can help when Wi-Fi is unstable, particularly for a computer running continuously. It does not reduce bitrate or the amount of data sent. Use it as a reliability measure, not as a data-saving setting. If you need to understand the practical cost of running your own computer continuously, the FFmpeg 24/7 YouTube loop guide also covers the operating trade-offs around a self-managed setup.
Test the revised stream with representative content
Create a test that resembles the real channel. Include the loudest and quietest audio, the fastest movement, the densest text, transitions, overlays, and any points where the loop changes sharply. A single still screen can conceal problems that appear once the programme starts moving.
Run the test long enough to observe the connection rather than stopping at the first clean minute. You do not need to invent a pass percentage. Look for repeated dropped frames, encoder overload, upload instability, visible blocking, unreadable text, audio interruptions, and a stream that fails to reconnect as expected.
Check the YouTube live control room and the viewer playback separately. The control room can show stream health and ingestion information, while a second device can reveal how the delivered stream appears away from the OBS computer. A phone on mobile data is useful for checking a different viewing path, but it may introduce its own quality changes.
For a looped video, inspect the restart moment as well as the middle of the programme. If a scene goes black, audio pops, or the file restarts incorrectly, lowering bitrate will not solve it. The guide to loop seams, black frames, and audio pops is relevant when the stream is technically connected but the programme itself has a bad transition.
If OBS shows a black preview or the output is not the expected scene, resolve that before comparing bitrates. The OBS black-screen troubleshooting guide for YouTube Live covers a different failure from high data usage, but it can prevent you from drawing conclusions from an invalid test.
Once a profile works, observe the stream at different times of day if the connection varies. Do not assume that a setting that worked during a quiet afternoon will behave identically during a busy evening. Record the profile, the measured outgoing bitrate, and the symptoms you saw so that the next change is deliberate.
Check your provider’s data-accounting rules
Your calculation answers how much the stream could send. Your provider’s account determines how that traffic is measured, displayed, and treated under your plan. Check the current terms and usage page for your exact broadband, fibre, mobile, or fixed-wireless plan.
Look for whether the allowance covers upload as well as download. A provider may show combined usage, separate directions, an account-wide total, or a router meter that is not the same as the provider’s billing meter. A mobile plan may also distinguish phone use from hotspot or tethering, while a home plan may apply a different policy.
Do not assume that “unlimited” means every plan condition is identical. Read the fair-use wording, speed policies, billing period, and any terms for continuous use. Conversely, do not assume that a usage warning means the stream alone caused it. Compare the timestamp and amount with other devices, backups, updates, and security cameras on the same account.
Use your own meter to validate the estimate. Note the reading before a controlled stream, keep other traffic as quiet as practical, and note the reading afterwards. The difference will still include measurement rounding and protocol overhead, but it gives you evidence about how that particular provider reports usage.
If the provider’s units do not match your calculation, first check decimal GB versus GiB and whether the meter includes both upload and download. Then ask support which traffic is included and when the usage counter updates. There is no responsible India-wide quota rule to substitute for those current plan terms.
Balance data savings against viewing quality
The lowest bitrate is not automatically the best profile. A devotional channel may prioritise clear song artwork and stable audio. A study channel may need readable slides. A local news loop may need sharp text. An ambience station may accept a simpler image if the audio remains clean and the movement is slow.
Compare profiles using the same questions:
| Question | Why it matters |
|---|---|
| What total bitrate is actually sent? | It determines the starting point for the data estimate. |
| Is the output resolution large enough for important text? | Lower resolution can make labels and tickers difficult to read. |
| Does the frame rate suit the movement? | Lower frame rate may be acceptable for still scenes but distracting for fast motion. |
| Does the selected codec match YouTube’s current guidance? | The live bitrate recommendations differ by codec and format. |
| Is there upload headroom? | A profile that consumes all available capacity is vulnerable to variation. |
| What does the provider count? | The plan’s accounting rules determine how the estimate appears on the account. |
Make the choice from the actual programme, not from a generic “best OBS settings” list. If a lower profile makes essential text unreadable or creates distracting artefacts, the data saving may not justify it. If the scene is mostly static and the original profile is sending more detail than viewers need, a lower output can be a sensible compromise.
If keeping a local computer online all night is the larger difficulty, a cloud-based YouTube-only service such as StreamNeo can remove the need for your own computer to remain switched on, while you still need to choose and check the stream settings that determine upload data. That is a different operating choice from reducing bitrate on OBS, and it does not change the need to understand your plan’s accounting rules.

FAQ
How much data does a 24-hour YouTube livestream use?
Multiply the total outgoing bitrate in Mbps by 10.8 for an approximate number of decimal GB over 24 hours. For example, 3 Mbps is about 32.4 decimal GB before variation and overhead. Add audio if your bitrate figure covers video only, then compare the result with your provider’s own accounting rules.
What OBS bitrate should I use to save data?
Use the lowest bitrate that keeps the important parts of your actual scene usable and remains stable on your connection. A static display may tolerate a lower setting than fast footage or a news ticker, and lower bitrate does not preserve the same picture quality. Check YouTube’s current codec-specific recommendations before selecting the final profile.
Does YouTube transcoding reduce my upload data?
No. YouTube creates different playback formats for viewers after receiving the source stream, but OBS still uploads the selected source bitrate. To reduce upload data, change the stream profile in OBS or use a different operating arrangement.
Will Ethernet reduce the data used by OBS?
No. Ethernet can improve reliability when Wi-Fi is unstable, but it does not reduce the stream bitrate or the amount of data sent. Treat it as a connection-stability measure and continue to estimate usage from the outgoing bitrate.
