For a Hindi radio livestream with a still image or simple visual, start in OBS with 1280×720 at 30 fps, H.264, CBR at 6 Mbps, a 2-second keyframe interval, and stereo AAC at 44.1 kHz and 128 kbps. This matches YouTube’s published H.264 recommendation for 720p30 and is a sensible starting point for a low-motion broadcast.
Those settings are not Hindi-specific, and they are not guaranteed to work on every connection or computer. If your stable upload cannot sustain the baseline, test a lower YouTube-supported resolution and bitrate combination rather than allowing an overnight stream to struggle.
The practical starting profile
A radio stream usually needs clean, uninterrupted sound more than it needs a fast-moving picture. Your visual might be a presenter card, a station logo, a scrolling schedule, album artwork, or a slow background loop. That makes 30 fps a reasonable starting point, provided the computer and network can maintain it.
Use the following as a baseline in OBS:
| Setting | Starting value | Why it is used |
|---|---|---|
| Output resolution | 1280×720 | YouTube’s published H.264 recommendation applies to 720p30 |
| Frame rate | 30 fps | Suitable for a mostly static or gently moving radio visual |
| Encoder | H.264 | The codec used by the cited YouTube 720p30 bitrate guidance |
| Rate control | CBR | YouTube recommends constant bitrate for live encoding |
| Video bitrate | 6,000 kbps | YouTube’s recommended H.264 bitrate for 720p30 |
| Keyframe interval | 2 seconds | YouTube’s current guidance |
| Audio codec | AAC stereo | YouTube’s published audio recommendation |
| Audio sample rate | 44.1 kHz | YouTube’s stereo sample-rate recommendation |
| Audio bitrate | 128 kbps | YouTube’s published stereo audio bitrate |
| Transport | RTMPS where supported | YouTube recommends RTMPS for ingestion |
YouTube’s live encoder settings and bitrate table is the authority for the platform values. OBS exposes the relevant output, video and audio controls in its own streaming guide, but the presence of a setting in OBS does not mean every value is suitable for every YouTube destination.
The 720p30 choice is editorial rather than linguistic. Hindi speech, Hindi song titles and Hindi audience preferences do not create a separate video encoding standard in the cited guidance. The same starting profile can suit an English, Bengali or multilingual audio-led channel when the picture has similar movement and the connection has similar capacity.
Set 1280×720 at 30 fps
Open OBS and look at the Video settings. Set the output, or scaled, resolution to 1280×720 and the common frame rate to 30 fps. If your canvas contains sources designed for another shape or size, arrange those sources carefully rather than stretching faces, logos or text until they look distorted.
The canvas resolution is the working area in which OBS composes your scene. The output resolution is what OBS sends to YouTube. For a simple radio scene, keeping the canvas and output close to the source design can reduce unnecessary scaling, but the output sent to YouTube is the value that matters for the published bitrate target.
A 30 fps stream sends fewer frames than a 60 fps stream. That matters because higher frame rates generally require a different bitrate target and create more work for the encoder and upload connection. A station visual with a logo, presenter photograph and occasional text change usually has no obvious benefit from 60 fps. A video with rapid dance footage, sports clips or frequent camera movement is a different case.
If you are deciding between 30 and 60 fps for an always-on channel, the guide to when 30 fps beats 60 fps for 24/7 loops gives you a useful way to think about movement, file design and operating load. Do not choose 60 fps simply because the number sounds more advanced. Choose it when the visual actually contains movement that benefits from it and the rest of the chain can support the change.
Check text at the intended viewing size. A small Devanagari ticker can become difficult to read after scaling or compression, even when the stream is technically healthy. Use sufficient contrast, avoid placing important text at the extreme edges, and watch the preview at normal size rather than judging only the large OBS canvas.
Configure H.264, CBR and the keyframe interval
In OBS’s Output settings, select the streaming encoder that provides H.264 if it is available and reliable on your computer. Hardware H.264 and software H.264 can both be practical, but the available encoder names and controls depend on your operating system, graphics hardware and OBS installation.
Set the rate control to CBR, or constant bitrate, and enter 6000 kbps for the video bitrate. YouTube lists 6 Mbps as the recommended H.264 bitrate for 720p at 30 fps and 3 Mbps as the listed minimum. The recommendation describes the target sent to YouTube; it does not promise that your broadband line can upload it continuously.
Set the keyframe interval to 2 seconds. YouTube’s guidance says not to exceed 4 seconds, so leaving the field blank, using an unusually long interval, or assuming that keyframes only matter for fast video is unhelpful. Keyframes give the platform regular full reference points from which later frames can be reconstructed.
Do not copy 6 Mbps to a different codec or resolution without checking the table again. YouTube publishes different recommended bitrates according to codec, resolution and frame rate. A value suitable for 720p30 H.264 is not automatically the right value for 1080p, 60 fps, HEVC or AV1.
The encoder preset is a separate decision. A slower preset can increase the work done by a software encoder, while a hardware encoder may expose different quality and performance controls. For an overnight radio broadcast, a setting that remains stable on your actual machine is more useful than an ambitious preset that causes encoding lag after several hours. Watch OBS’s rendering and encoding indicators during a representative test.
Keep the stream key private. It authorises an encoder to send to your YouTube channel, so treat it like a password and do not paste it into screenshots, public documents or support posts. Prefer RTMPS when the encoder and destination support it, following YouTube’s current instructions for the server URL and stream key.
Set stereo AAC audio at 44.1 kHz and 128 kbps
For the audio output, use AAC stereo at 128 kbps and set OBS’s sample rate to 44.1 kHz. These values follow YouTube’s published stereo recommendation. The sample rate should also match your computer, mixer or audio interface where that equipment allows it, because unnecessary mismatches can introduce conversion or device problems.
In OBS, check Settings, Audio, and set the sample rate to 44.1 kHz. Then inspect each audio source. A microphone, music player, browser source and capture device may not all follow the same device setting. If an interface insists on another rate, avoid changing several parts of the chain at once. Identify which device is controlling the rate and test the complete path.
Stereo is appropriate when your programme contains music, jingles and a presenter microphone arranged across two channels. If the source is genuinely mono, do not create a false wide effect merely to make the meters look different. A centred voice with consistent level is easier to understand than an artificially spread voice.
Watch the audio meters while the loudest realistic material is playing. Hindi speech can include quiet passages followed by emphatic phrases, while music and station jingles may have a much higher average level. Set levels so ordinary speech is clear without allowing loud music or processing to remain in the red. A limiter can help catch peaks, but it cannot repair clipping that has already occurred upstream.
Listen through headphones as well as speakers. Headphones can reveal hum, duplicated audio, a delayed microphone, music leaking into the microphone, or one channel disappearing. Leave enough time in the test to hear a presenter speaking over music, because a clean music-only check does not prove that the complete radio mix is usable.
YouTube’s audio value is a delivery setting, not a replacement for a good source recording. Noise, distortion, aggressive compression and room echo are present before YouTube receives the stream. Fix those at the microphone, mixer or source file instead of expecting a bitrate change to remove them.
Check stable upload capacity, not peak speed
A speed test can show what your connection achieved at one moment. A 24/7 stream needs the upload to remain usable while the household, office or studio connection is doing other work. YouTube itself recommends running a speed test to test upload bitrate, but a peak result should not be treated as stable capacity for an overnight broadcast.
At the baseline, OBS is sending about 6 Mbps of video, plus audio and protocol overhead. The practical question is not whether a test briefly reaches 6 Mbps. It is whether the connection can maintain the selected stream rate without repeated congestion, packet loss or interruptions during the hours when the channel is meant to be live.
Run tests at different times, including a period when other people use the connection. Pause large uploads, cloud backups and security-camera transfers during the test, then repeat with normal household conditions. If the result changes materially, that variation is part of your operating environment and should influence the profile you select.
A wired connection is often easier to diagnose than Wi-Fi because it removes one variable between the computer and router. It does not solve an overloaded broadband line, a failing router or an unstable internet provider, but it can tell you whether the wireless segment is contributing to the problem. If wired and wireless results differ, test the chosen stream on the connection you will actually use.
OBS can show dropped frames caused by the network, while encoding and rendering indicators point to different problems. Dropped frames suggest that data is not reaching YouTube as intended. Encoding lag suggests that the computer cannot produce frames quickly enough. Rendering lag can indicate that OBS is struggling to compose the scene. The guide to reading dropped frames on a long stream explains why these signals should not be treated as one generic failure.
Do not solve every problem by lowering audio quality first. For an audio-led station, speech and music are the programme. First identify whether the issue is network, encoding, rendering or the source audio. Then change one meaningful variable and test again so you know what actually helped.
Test the complete stream before committing
Create an unlisted test stream or use YouTube’s available testing workflow. Include the same visual scene, Hindi speech, music, jingles and source devices that you expect to use on the real broadcast. A test with a silent placeholder image and no microphone does not exercise the parts most likely to fail.
Check the Live Control Room preview before making the stream public. YouTube advises testing before starting and continuously monitoring audio and video quality. Watch for a stable preview, clear audio, readable text, correct aspect ratio and a sensible delay between OBS and the preview.
Leave the test running long enough to expose ordinary problems. A short connection check may miss router renegotiation, a laptop entering a power-saving state, a cloud backup starting, or an audio device changing after a period of inactivity. You do not need to invent a guaranteed duration; the useful point is to test under the conditions and for the type of run you actually plan.
When the stream is active, compare three places: OBS, YouTube’s Live Control Room and the viewer-facing page. OBS tells you what your computer is attempting to send. YouTube can report ingestion and stream health. The public page shows what a viewer receives, including audio balance, picture quality and the effect of delay.
For a channel intended to run after you leave the desk, remove the computer as a single point of failure where practical. An uploaded programme can be prepared once and then sent continuously without leaving the personal computer running. StreamNeo removes the particular burden of keeping OBS open overnight by taking an uploaded video, your YouTube stream key and the ongoing broadcast process out of the local desktop; you still need to prepare the content, check rights and monitor the channel.
If you want to understand the wider workflow before choosing a delivery method, see how to stream a pre-recorded video as live on YouTube. If the programme should begin at a planned time, scheduling a live stream from an uploaded video covers a related decision. These are workflow questions, not reasons to change the OBS bitrate without testing.
Adjust to a supported combination
If the 6 Mbps baseline is unstable, do not keep restarting the same profile and hope the connection settles. Record what failed, reduce the demand in a controlled way, and test a supported YouTube combination. The available lower choice depends on the codec, resolution and frame rate you are using, so check YouTube’s current table rather than inventing a value between rows.
For H.264 720p30, YouTube lists 3 Mbps as the minimum and 6 Mbps as the recommendation. The lower figure is not a promise of identical picture quality or a universal solution. It is a documented point to test when the recommended target cannot be sustained. A static station card may remain acceptable at a lower setting, while a busy visual with scrolling text may show compression sooner.
You might also decide that a lower resolution is more appropriate for the connection. Make that choice based on the visual and audience needs, not on the label “radio”. A large Devanagari title, timetable or phone number may need a clear layout even if the background barely moves. Conversely, a simple logo and album title may remain readable with less video data.
Change one variable at a time where possible. For example, test the recommended 720p30 profile, then a documented lower 720p30 combination, before changing resolution, frame rate, codec and audio together. This makes the result easier to understand and gives you a usable record for the next troubleshooting session.
If the computer cannot encode reliably, examine the available H.264 hardware encoder before changing the YouTube target. If no suitable encoder is available, a different codec may be supported by YouTube, but its published bitrate guidance and OBS controls will be different. Do not transplant H.264 values to HEVC or AV1 by assumption.
A stable lower profile is generally preferable to a higher profile that repeatedly disconnects. That is a practical operating judgement, not a promise that any particular setting will produce a given audience result. Continue monitoring after the change because a profile that works during a quiet afternoon may behave differently when the connection is busy.
Check rights and channel readiness
Technical settings do not grant permission to broadcast music. YouTube’s live-stream terms state that the provider must hold the necessary rights for live content on Google services, including relevant music licensing rights. Review the current terms and the licence for every track, recording, voice clip and programme element you plan to use.
YouTube says live streams are scanned for third-party content. A match can lead to a placeholder, interruption or termination, and a licence does not necessarily prevent an automated interruption if the rights holder requires the channel to be allowlisted. Read YouTube’s copyright guidance for live streams and confirm the rights holder’s requirements rather than relying on a label such as “royalty-free” or “free to use”.
YouTube’s safer music guidance points to public-domain material, music used with permission and resources such as the YouTube Audio Library. Check whether a particular licence covers live streaming, the countries where viewers may watch, commercial use and continuous or repeated broadcasts. A track that is permitted in an ordinary uploaded video may have restrictions for live use.
Also check channel eligibility before planning a long broadcast. YouTube’s live-streaming setup guidance describes verification, restrictions and age requirements. The research basis for this article notes that YouTube requires a verified channel with no live-streaming restrictions in the prior 90 days and specifies a minimum age of 16. Review the official page because platform requirements can change.
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
Are these settings specifically required for Hindi livestreams?
No. Hindi does not require a separate encoder profile in the cited YouTube guidance. The 1280×720 at 30 fps baseline is a practical choice for an audio-led programme with a mostly static visual, regardless of language.
Is 6 Mbps the minimum upload speed I need?
YouTube lists 6 Mbps as the recommended H.264 video bitrate for 720p30 and 3 Mbps as its listed minimum. Your connection must also carry audio and overhead, and a speed-test peak does not prove that the line can sustain the stream continuously.
Should a radio channel use 60 fps?
Usually not when the visual is a logo, still image, schedule or gentle background loop. Consider 60 fps only when the picture contains movement that benefits from it and your encoder and stable upload can support the corresponding YouTube bitrate guidance.
Can licensed music still interrupt a YouTube live stream?
Yes. Automated detection can interrupt a stream even when you have a licence if the rights holder requires allowlisting or has not recognised the channel. Confirm live-stream permission, territory coverage and any allowlisting requirement with the relevant rights holder before broadcasting.
