For 4K/2160p at 60 fps on YouTube Live, set OBS video bitrate to 50 Mbps for H.264, or 35 Mbps for AV1 or H.265/HEVC, matching the codec you actually use. Those are YouTube’s recommended video bitrates, not proof that your Airtel Xstream Fiber connection can sustain them.
Your plan name cannot settle that question: upload performance depends on the connection at your address and the conditions on your local network. Measure from the computer that will stream, then run a representative test and check YouTube’s stream health before relying on 4K60.
Match OBS bitrate to the selected codec
Start by checking which video encoder and codec OBS will send. The same resolution and frame rate can call for different bitrates depending on codec, so there is no single correct 4K60 number independent of that choice. YouTube supports H.264, H.265/HEVC and AV1 over RTMP or RTMPS ingest; use the corresponding recommendation in its encoder settings guidance.
In OBS, select constant bitrate (CBR) for the stream, set the keyframe interval to two seconds, and choose RTMPS where your workflow offers it. YouTube recommends a two-second keyframe frequency and says not to exceed four seconds. These settings help YouTube receive a predictable feed; they do not make an undersized or variable upstream connection reliable.
Codec availability depends on the encoder choices exposed by OBS and the computer’s hardware. Do not assume that a codec appearing in YouTube’s documentation is available in your setup, or that changing the codec will automatically solve a network constraint. Check the encoder actually selected in OBS, then apply the matching bitrate rather than copying settings intended for another codec.
For a standard SDR stream, YouTube’s guidance specifies Rec. 709 colour and 8-bit video, with progressive scan in its advanced settings. If you are intentionally producing HDR, its guidance instead specifies H.265/HEVC and 10-bit. Keep the output format aligned with the material you are producing; changing colour settings is not a substitute for testing upload capacity.
Know YouTube’s 4K60 bitrate recommendations
YouTube’s current encoder guide gives these recommended video bitrates for 2160p at 60 fps:
| OBS video codec | YouTube-recommended video bitrate | What to check |
|---|---|---|
| H.264 | 50 Mbps | Use this figure when H.264 is the selected codec |
| H.265/HEVC | 35 Mbps | Confirm OBS and your encoder can output HEVC |
| AV1 | 35 Mbps | Confirm AV1 is available in your selected workflow |
These are not three interchangeable quality presets. They are codec-specific recommendations from YouTube, so the first decision is which supported codec your actual encoder is sending. If you select H.264, the relevant YouTube recommendation is 50 Mbps; if you select AV1 or H.265/HEVC, it is 35 Mbps. The source for these figures is YouTube Help; its page provides current guidance but does not give a publication date.
Treat the recommended figure as the target to test, not as an obligation to force through a line that cannot sustain it. YouTube advises choosing quality that your connection can reliably support and recommends testing upload bitrate before a live event. If the target rate repeatedly produces dropped frames or poor stream health, use a lower bitrate or step down output quality. A consistent 1440p or 1080p stream is more useful to viewers than a 4K60 stream that regularly stalls.
The bitrate setting in OBS is also not a measurement of your connection. Entering 50 Mbps does not mean your computer has 50 Mbps of usable upload, and a momentary speed-test result above that level does not show that the route to YouTube will remain clear during a long broadcast. The settings and the available upstream capacity are separate parts of the decision.
Account for audio and other upstream use
OBS’s video bitrate is only part of what the connection must carry. Audio adds to the outbound stream, and other devices or applications may also use upload capacity. YouTube lists 128 kbps for stereo audio; even though that is small beside a 35 or 50 Mbps video stream, it belongs in the total rather than being mistaken for free capacity.
Other upstream traffic can be less predictable than the stream itself. A phone backing up photos, a cloud drive syncing large files, a security camera uploading footage, or another person sending files can compete with OBS. The effect depends on how much capacity is available and how traffic is shared. Do not assume that an internet connection with a high advertised headline speed will leave enough clean upload for a constant live feed.
Before a planned broadcast, pause avoidable uploads and ask household members not to start large transfers during the test. Then repeat the test with the ordinary devices and services you expect to have active during the real stream. If the household cannot avoid those uses, test with them running rather than measuring only in an artificially quiet period.
If the connection has little spare capacity, consider reducing OBS bitrate below the YouTube recommendation and/or reducing resolution or frame rate. This is a trade-off: the stream may have less detail or motion clarity, but it can be more dependable. Use the actual YouTube test and stream-health feedback to decide, rather than choosing a lower number on intuition alone.
Why Airtel plan names do not prove upload capacity
Airtel Xstream Fiber is not one universal upload tier. Airtel lists multiple broadband plans and notes that availability varies by location on its broadband plans page. The plan label, a speed shown in an advert, or a figure discussed by another customer cannot establish sustained upload at your address, on your router, to YouTube’s ingest service.
Airtel’s quality-of-service report for the quarter ending December 2025 includes tariff-specific population figures. For example, it lists 30 Mbps offered typical upload and 30 Mbps 90th-percentile measured upload for tariff 398, and 40 Mbps typical upload with 43 Mbps 90th-percentile measured upload for tariff 499. These are figures for those tariffs in that reporting period, not a promise for an individual subscriber or a current guarantee of a continuous YouTube route. The Airtel QoS report is useful context, but it cannot replace measuring your own line.
This matters especially for the H.264 recommendation: 50 Mbps video alone is higher than the reported typical upload examples above. The HEVC or AV1 recommendation of 35 Mbps is also not established by those figures for an individual line. Do not infer from this comparison that any particular Airtel plan will or will not work. The reporting data is not your address-level sustained result, and the plan menu can vary by place.
If you are choosing a plan, ask Airtel what upload speed is available for the exact address and plan, then verify it in practice. If you already have service, test before deciding whether to change plans or output settings. A plan name is a useful clue about the service offered, but the representative test from your streaming computer is the decisive practical check.
Measure upload on the streaming computer
Run upload tests on the same computer, in the same room, and using the same network arrangement you intend to use for the broadcast. YouTube itself says, “We recommend running a speed test to test your upload bitrate.” A test on a phone beside the router, a work laptop on another floor, or a computer connected by a different route says less about the stream setup you plan to trust.
Where practical, test with the streaming computer connected to the router by Ethernet. This removes Wi-Fi variation from the local link as one possible source of trouble. It cannot add upload capacity that the Airtel connection does not supply, and a wired result is not a guarantee that the broadcast will remain stable. If Ethernet is not practical, test over the Wi-Fi network and location that will actually be used, with the computer in its final position.
Repeat measurements at different times, including times when the household normally makes heavier use of the connection. A single result can be a snapshot of a quiet moment. Note both the result and the conditions: wired or Wi-Fi, time of day, and whether other people or devices were active. The purpose is not to produce a flattering peak number but to learn whether upload headroom appears consistently available.
Compare the observations with the video bitrate you intend to send, remembering that audio and competing traffic add load. Do not treat a test result that only just clears the video figure as ample capacity. Nor should a test result be read as a stability certificate: a speed test is a brief measurement, while a broadcast must keep sending for as long as you are live.
A direct Ethernet connection is a sensible troubleshooting step when Wi-Fi may be contributing to variation. A Cat 6 cable can be an optional way to make that wired connection if the computer and router support it; it is not a cure for insufficient upstream service. For the related issue of recurring drops, the guide to why a YouTube podcast stream may disconnect in India covers other connection symptoms worth separating from the bitrate setting itself.
Test under representative network load
After measuring upload, test the actual OBS profile with a private or unlisted YouTube broadcast. Use the planned resolution, frame rate, codec, bitrate, audio, and scene or file. A static desktop is not a meaningful stand-in for a devotional music loop with moving visuals, a news loop with changing footage, or a study stream with screen motion. YouTube advises testing with audio and movement similar to the planned stream.
Keep the test running long enough to observe variation rather than stopping as soon as it connects. Use the household’s normal network pattern: if someone is likely to stream video or upload work while your 24/7 channel runs, include that condition in at least one test. If your stream only behaves when everything else is disconnected, that is a useful limit to know before scheduling a long broadcast.
Watch OBS’s dropped-frame indicators and YouTube Live Control Room’s stream health and messages. These provide complementary evidence: OBS can show that frames are not reaching the output cleanly, while YouTube reports how its ingest is receiving the stream. Neither a successful start nor a green status at one moment proves the line will remain stable overnight.
If the test degrades, change one variable at a time. First check whether another upload or Wi-Fi variation is involved. Then reduce bitrate or lower resolution/frame rate and repeat the test. If a lower-rate profile behaves well under representative conditions, use that profile rather than insisting on 4K60 because the plan headline or a brief speed test appeared sufficient.
For a channel built around a prerecorded playlist, the streaming computer still has to encode and send the signal continuously. The practical guidance in building a 24/7 Assamese music YouTube channel with OBS can help with the broader OBS workflow, while bitrate and network tests determine whether this specific 4K profile is suitable.
Check stream health before relying on the connection
A connection can show enough upload in a test and still have interruptions during a real broadcast. YouTube’s stream-health messages and OBS’s dropped frames should be checked during the private test and again after the public stream begins. Look for repeated warnings, rising dropped frames, audio issues, or a broadcast that disconnects and reconnects rather than treating a single successful test as a permanent verdict.
For 4K streams, YouTube says low-latency optimisation is unavailable and streams are set to normal latency. Plan around that behaviour if viewers expect an interactive session; a 4K60 setup is not the right choice simply because it offers more pixels. For a continuous ambience or bhajan channel, reliable playback may matter more than the highest output format.
If you need a channel to continue while the household computer is off, that is a separate operational requirement from choosing OBS bitrate. StreamNeo can remove the need to leave that computer running by turning an uploaded video into a YouTube live stream, which addresses the specific burden of keeping the local machine on for a continuous file-based broadcast. It is YouTube-only; the bitrate decision for an OBS broadcast remains a matter of matching the codec and testing the connection.
If you are instead keeping OBS on a local machine, consider whether its power, software state, and network are suitable for an always-on job. The practical article on configuring OBS for a 24/7 stream on a low-power mini PC addresses the computer side; it does not replace the upload test described here. Whichever arrangement you use, test the actual stream before a devotional programme, local news loop, or scheduled event depends on it.

FAQ
What bitrate should I use for 4K 60fps YouTube Live?
Use 50 Mbps for H.264 or 35 Mbps for AV1 or H.265/HEVC, based on YouTube’s current 2160p60 recommendations. Confirm the codec selected in OBS before setting the bitrate. Audio and other upstream use add to the total load.
Is my Airtel upload speed enough for 4K60?
The plan name alone cannot answer that, and no measured speed guarantees a stable broadcast. Test upload from the actual streaming computer at different times, then run a representative private or unlisted stream and check OBS and YouTube stream health. Reduce bitrate or output quality if the test is unstable.
Should I use H.264 or HEVC/AV1?
Use the codec your OBS encoder and hardware can actually produce, and apply YouTube’s matching recommendation: 50 Mbps for H.264, 35 Mbps for HEVC or AV1. Availability and suitability depend on your setup. The best choice is the supported codec that works reliably in a representative stream test.
Does Ethernet guarantee a stable 4K60 stream?
No. Ethernet can remove some Wi-Fi variation between the computer and router, but it cannot create more upstream capacity from the ISP or guarantee a clear route to YouTube. Test using the final wired or Wi-Fi arrangement, with ordinary network load, before relying on it.
