For an always-on YouTube stream over an Indian 4G hotspot, treat 1280×720 at 30 fps as a starting format to test, not a promise that your connection will hold it. Set OBS to H.264, CBR and a two-second keyframe interval, then choose a bitrate your hotspot can sustain during a representative test.
YouTube’s published H.264 recommendation for 240p–720p at 30 fps is 4 Mbps, but that is an encoder setting reference, not a measurement of your local carrier or a guarantee of stable service. Test where the hotspot will run, watch YouTube’s stream health, and reduce output settings if the connection has persistent trouble.
Test the hotspot where it will run
A speed test taken at another time, in another room or beside a different mobile mast does not tell you whether the hotspot can sustain a broadcast from the place you plan to leave it. Mobile upload can vary by location and conditions. The practical question is not the best result you have seen on a speed-test screen; it is whether the connection can carry your chosen stream over a meaningful test session without persistent health warnings or dropped connection.
Start by placing the phone or hotspot where it will stay during the stream. Use the same SIM, plan, Wi-Fi arrangement and computer you expect to use. Check upload speed more than once and at the times you expect to be broadcasting. YouTube recommends testing upload bitrate, but a short result is only a snapshot. It does not prove the link will be steady through a night, a busy period or a change in signal conditions.
Before opening OBS, check the practical constraints around the connection. Confirm how your mobile plan counts data and whether it has a limit or terms relevant to continuous use. Make sure the device can remain powered, has room to shed heat, and does not depend on being moved or handled while streaming. These are checks, not fixes: a router, antenna, power bank or different location may or may not help, and the result has to be measured at your site.
If you are assembling the rest of the setup as well, the budget-friendly setup checklist is useful for thinking about power and equipment that need to last beyond a short test. Keep the mobile connection as a separate item in that checklist. A reliable computer or a tidy scene cannot compensate for upload that is not sustained.
Start with 720p30, then test lower if needed
In OBS, set the output to 1280×720 at 30 frames per second for the first test. This is a reasonable place to begin when you want to balance a clear picture with a lower upload demand than some higher-resolution or higher-frame-rate formats. It is not a universal setting for every Indian 4G connection. The right result depends on your carrier, location, equipment and the content being sent.
A devotional image with slow movement and a lofi animation may be less demanding visually than a local news loop with frequent cuts or scrolling graphics. The selected bitrate still has to be carried upstream continuously, but representative motion helps you judge whether the picture remains acceptable at the chosen settings. Do not tune against a static desktop if the real scene contains movement, transitions or text.
If the connection struggles at 720p30, reduce output resolution or frame rate and test again. Change one setting at a time so you can tell what improved the result. A lower setting is not a failure if it gives viewers a stable stream and the picture suits the material. For a mostly static ambience scene, a modest image may be entirely usable; for text-heavy news, make sure the lower resolution keeps important details legible.
Use OBS’s output settings rather than changing several unrelated scene elements at once. If you need help choosing a broadcasting workflow for a radio-style channel, the guide to free software for a 24/7 YouTube radio stream covers the broader software decision. Here, keep the experiment narrow: format, bitrate, and the result YouTube reports.
Set H.264, CBR and a two-second keyframe interval
In OBS, choose an H.264 encoder your system supports. Depending on the computer, that may be a hardware encoder or a software option. The important point is to select H.264 output and test the result on the actual machine you intend to leave running. An encoder that is available in a menu is not automatically the best choice for your system; watch for encoding lag as well as network trouble during the test.
Set rate control to CBR, or constant bitrate, and enter the video bitrate you are testing. CBR aims to send video at a steady target rate rather than varying the rate with each moment of complexity. That makes the expected upload easier to compare with the available connection, although it cannot make an insufficient or variable mobile link reliable. If you select 4 Mbps for video, for example, that is the video target, not the whole network load.
Set the keyframe interval to two seconds. YouTube’s live encoder guidance lists a two-second keyframe interval. In OBS, field labels can vary slightly by encoder, so check the selected encoder’s controls and verify the setting before you go live. Use RTMP or RTMPS as supported by YouTube; YouTube recommends RTMPS for encrypted transport. Use the stream key from YouTube Studio carefully and do not share it publicly.
For audio, select AAC stereo and use 128 kbps as the YouTube-listed recommended stereo audio bitrate. Audio adds to the video payload and to the total connection demand. If your stream is mainly a playlist, listen through transitions and loop points as part of the test rather than checking only that OBS meters move. The guide to fixing loop seams, black frames and audio pops can help you assess the restart moment in content that repeats.
Choose a bitrate using guidance and sustained results
YouTube publishes recommended H.264 bitrates for different output formats. Use the figures as platform guidance, then compare them with your sustained upload test and the stream-health result. They are not recommendations for a particular Indian carrier, location or hotspot model.
| Output format | YouTube H.264 video bitrate reference | How to use it |
|---|---|---|
| 240p–720p at 30 fps | 4 Mbps | A reference for testing 720p30; lower the output if this is not sustained cleanly |
| 720p at 60 fps | 6 Mbps | More demanding than 720p30; test only if the content benefits from the extra frame rate and upload allows it |
| 1080p at 30 fps | 10 Mbps | A higher-demand option; it may not suit a variable mobile connection |
These figures come from YouTube Help’s live encoder settings. A listed bitrate is an encoder target, not a promise that viewers will receive a particular quality, nor evidence that your hotspot can carry it. Begin at 720p30 and the corresponding reference, then keep it only if the real test remains healthy. If warnings or disconnects persist, move down in a controlled way and test again.
Allow for audio and network overhead when thinking about total upload. The video bitrate is not all the data travelling over the connection. Avoid treating a speed-test result that barely reaches the video target as proof of margin; the connection can vary, and the stream also carries audio and protocol traffic. The evidence does not establish a universal safety margin for Indian hotspots, so use observed health over a representative test rather than inventing one.
Data allowance matters just as much as speed. At a steady video bitrate, the video payload alone is approximately 43.2 GB over 24 hours at 4 Mbps, 64.8 GB at 6 Mbps and 108 GB at 10 Mbps. These are arithmetic estimates using decimal gigabytes and exclude audio, protocol overhead, retransmissions and variable-rate behaviour. Your carrier’s accounting may differ. Check the plan’s current data terms and run a shorter session before you commit to continuous use.
Test with the scene, sound and movement you will actually stream
Make an unlisted or otherwise suitable test broadcast before committing to a public continuous channel. Use the actual scene, the actual file or playlist, and the audio that viewers will hear. YouTube specifically recommends testing before a live stream and testing with representative content. A clean test with a blank screen may miss the load or quality issues that appear when a visualiser, scrolling text or video loop is active.
Include the material that can expose weak points: a transition between files, a scene change, animated graphics, moving footage or a section with a louder audio passage. Watch the OBS preview and the YouTube result, not just the encoder status. A stream can appear normal locally while the upstream connection is having difficulty. Give the test enough time to reveal more than an initial connection; a momentary successful start does not establish that it will run continuously.
Record what you changed and what happened. For example, note the resolution, frame rate, bitrate, time, hotspot placement and any YouTube health warnings. If you need to adjust, change one item and repeat the comparable part of the test. That keeps cause and effect clearer than changing bitrate, resolution, scene complexity and hotspot position in the same attempt.
When a long-running stream repeatedly needs a person to keep a computer on, reconnect it or restart a failed broadcast, that becomes a separate operational burden from choosing OBS settings. StreamNeo can remove that particular need to leave your computer running for a file-based YouTube stream, but it does not change whether your mobile connection, data plan or channel content is suitable for continuous broadcasting. You still need to check those constraints and observe the actual result.
Watch YouTube stream health and respond methodically
During the test, watch YouTube Studio’s stream health and connection status. Treat a healthy initial status as one observation, not a long-term guarantee. Keep an eye on it during the representative session, especially if the mobile device is in a location where signal conditions may change. OBS can also show dropped frames or encoding lag; distinguish network trouble from a computer that cannot encode the chosen scene smoothly.
If the health report points to connection trouble, first confirm that the hotspot has not moved, lost power or switched to a different network arrangement. Then reduce the stream’s demand: lower bitrate or output resolution, or reduce frame rate where suitable. Change one setting, allow a fresh test, and see whether the symptom changes. If trouble continues, follow OBS’s stream connection troubleshooting steps, which include checking connection-related causes and testing another server where applicable.
If YouTube appears to receive a healthy stream but playback looks poor to viewers, investigate the visual content and the viewer-side experience separately. YouTube transcodes live streams into multiple formats for viewers, so OBS does not need to send a separate rendition for every device. That does not eliminate the need for a stable source stream, nor does it ensure that every viewer’s network can play smoothly. For the distinction between a stream source and viewer playback, see why a 24/7 stream can buffer for viewers but not for you.
Keep a simple test record and repeat the process after a meaningful change, such as moving the hotspot, changing carrier or changing the content format. Check power, temperature and data allowance as part of preparing for a long session, but do not assume any one hardware purchase will solve upload variation. There is no sourced India-wide upload figure or carrier-specific setting that can replace a local test.

FAQ
What are good OBS settings for a 24/7 YouTube stream on a 4G hotspot?
Start by testing 1280×720 at 30 fps with H.264, CBR and a two-second keyframe interval. YouTube lists 4 Mbps for H.264 at 240p–720p and 30 fps, but the setting does not guarantee your hotspot can sustain it. Keep it only if a representative test has acceptable stream health.
Should I use 4 Mbps because YouTube recommends it?
Use it as YouTube’s encoder reference for that format, not as a connection guarantee. Test sustained upload at the intended location with the real scene and audio. If health problems persist, reduce bitrate or output settings and test again.
How much data does a 24/7 stream use?
At 4 Mbps, the video payload alone is approximately 43.2 GB in 24 hours using decimal gigabytes. Audio and network overhead add to that, and carrier accounting can differ. Check the plan’s allowance and terms before relying on it for continuous use.
Does a dedicated hotspot router guarantee a more stable stream?
No device can be assumed to improve stability without measuring it in your location. If you consider dedicated hardware, check carrier-band compatibility, local coverage, plan terms and any antenna compatibility, then compare sustained upload with your existing setup. A test remains necessary.
