For a nonstop YouTube bhajan stream on a low-end PC, start by testing 720p at 30 frames per second, then move to 480p30 if the computer cannot encode smoothly or the connection cannot sustain the required upload. This is a practical starting point for a mostly static or slow-moving devotional visual, not an official YouTube preset for bhajans or a guarantee for any particular computer.
YouTube's live-streaming guidance applies across the platform; it does not set a different keyframe interval or bitrate rule for India. Use OBS's two-second keyframe interval, test with the audio and movement you will actually broadcast, and keep the resolution your system can maintain without interruptions.
Start with the resolution, not the label “low-end”
A PC's age or price does not tell you precisely what it can stream. Performance depends on its processor, graphics hardware, available hardware encoder, OBS settings and other work happening on the computer. Your internet connection is a separate limit: a PC can encode a stream cleanly while the upload connection struggles to carry it, or the connection can be adequate while encoding overloads the machine.
For a bhajan stream built around an image, album art or slow visual movement, 720p30 is a sensible first test. At 30 fps, the picture updates less often than at 60 fps, and a mostly static scene usually gives you little practical reason to make the computer process twice as many frames. That is a content-based judgement, not a YouTube rule or a hardware benchmark. If the PC drops frames or shows encoding strain at 720p30, try 480p30 rather than insisting on a sharper picture.
The distinction matters during an overnight broadcast. A resolution that looks good in a brief preview is not necessarily one the computer and connection can carry continuously. YouTube also transcodes live streams into different output formats for viewers, so transmitting at 1080p solely to make your stream watchable on different devices is not necessary. Check YouTube's live encoder settings before you set up: current requirements and recommendations can change.
Open OBS streaming output settings
In OBS, open Settings from the Controls area, then select Output in the left-hand list. Find Output Mode near the top. If it is set to Simple, change it to Advanced so you can see the streaming encoder controls, including the keyframe interval. OBS labels and layouts can vary by version, but the controls are in the Output settings rather than the Video settings.
Within Output, open the Streaming tab. Choose the encoder your system supports and set the output resolution and frame rate in the relevant OBS settings. In Advanced mode, set rate control to CBR (constant bitrate) if it is available for the selected encoder, as YouTube's published encoder guidance recommends CBR. The exact names available for encoder and rate control depend on the hardware and software installed on your computer; do not assume that every PC offers the same hardware encoder choices.
If you are still learning OBS, work through each setting before the live session and note what you change. A resolution setting is not the same as the keyframe interval: resolution determines the dimensions of the picture, while keyframe interval controls how frequently the encoder sends a complete reference frame. Treating one as a substitute for the other makes it harder to diagnose a poor-looking or unstable stream.
Find Keyframe Interval in Advanced mode
With Settings → Output → Output Mode: Advanced → Streaming open, look for Keyframe Interval in the encoder settings. In OBS this control is commonly expressed in seconds. Enter 2 for a two-second interval. If the control appears in a different place or is named differently in your version, check that version's OBS documentation rather than changing an unrelated setting.
YouTube's encoder recommendations specify a two-second keyframe interval and say not to exceed four seconds. For this setup, use two seconds; do not raise it beyond YouTube's maximum in an attempt to save processing or bandwidth. A keyframe interval is not a resolution, frame-rate or bitrate control. Keep those settings matched to the PC and connection instead.
The platform guidance is not India-specific. Being in India may affect the upload connection you can sustain or the route your connection takes, but it does not create a separate Indian keyframe interval. Apply the same published YouTube encoder guidance, then test your own connection at the time and from the place you intend to broadcast.
Set two seconds, then understand the frame count
For a 30 fps stream, two seconds corresponds to 60 frames: 30 frames each second multiplied by two seconds. This is the frame-count equivalent, not a different recommendation. If a particular encoder asks for an interval in frames rather than seconds, 60 is the equivalent value for 30 fps. If OBS asks for seconds, enter 2 rather than converting it to 60.
That conversion is useful when reading encoder interfaces or comparing settings, but it does not mean you should set a 60-frame interval irrespective of frame rate. At a different frame rate, the number of frames that fit into two seconds changes. The duration is the important part of the recommendation: keep the interval at two seconds, then use the corresponding frame count only if the encoder requires it.
Avoid changing the interval repeatedly while troubleshooting unrelated symptoms. If the stream is buffering, first check OBS's dropped-frame and encoding indicators, the YouTube live control room's stream health messages, and the upload connection. If the video looks soft, assess resolution and bitrate. A two-second interval is a recommended encoder setting, not a remedy for weak upload capacity or an overloaded CPU.
Apply the same duration at other frame rates
The same two-second duration has a different frame-count equivalent at another frame rate. For example, at 24 fps it is 48 frames; at 25 fps it is 50 frames; and at 60 fps it is 120 frames. These values follow directly from multiplying frames per second by two seconds. Use them only where the encoder requests frames; if it accepts seconds, keep the setting at two seconds.
For a low-motion devotional stream, 30 fps is a practical starting point to test. Moving to 60 fps doubles the number of frames the encoder has to process each second compared with 30 fps, and may increase the workload without making a static background meaningfully better. That does not mean 60 fps is wrong for every stream: a channel with substantial movement may value smoother motion, provided the PC and connection sustain it. For a fixed image with a song playing, start with 30 fps and add frame rate only for a clear visual reason.
OBS's Settings → Video area is where you normally set the output frame rate and canvas or scaled output resolution; the keyframe interval remains under Output's Streaming encoder settings. Keep these controls distinct as you test. If you change the frame rate, leave the keyframe duration at two seconds and avoid accidentally changing the resolution or bitrate at the same time, because changing one variable at a time makes the result easier to interpret.
Choose bitrate for the connection
Resolution and frame rate help determine how much video detail is being encoded, while bitrate determines how much data the stream sends. YouTube's current H.264 guidance lists 8 Mbps as the recommended video bitrate and 3 Mbps as the minimum for 720p30. For 480p30, it lists 4 Mbps recommended and 0.4 Mbps minimum. These are YouTube's ingestion recommendations, not a promise that your particular internet connection can sustain them for a continuous broadcast. The figures are from YouTube Help, whose page does not state a publication year; recheck the current table before relying on it.
| OBS output to test | YouTube H.264 video bitrate guidance | Practical use |
|---|---|---|
| 720p30 | 8 Mbps recommended; 3 Mbps minimum | Start here if the PC encodes smoothly and the tested connection can sustain the stream. |
| 480p30 | 4 Mbps recommended; 0.4 Mbps minimum | Try this if 720p30 strains the PC or the connection cannot reliably carry the higher setting. |
The minimum is not a target for a reliable overnight stream. It is a published lower figure, not evidence that a connection operating close to it will have enough headroom for fluctuations. Test upload capacity and choose a quality your connection can carry reliably, as YouTube's live-streaming help advises. A speed test gives you a useful indication, but it cannot guarantee uninterrupted performance during a future stream.
Set a bitrate that is within the connection's sustained capacity, and leave room for normal variation rather than matching the measured upload figure exactly. If OBS reports dropped frames and YouTube reports insufficient incoming video, the connection may be the limiting factor. If frames are being missed during encoding while the connection remains stable, the PC or encoder may be the constraint. YouTube's LiveStreams API documentation describes stream health issues including low bitrate, frame-rate mismatch and insufficient incoming video; use the live control room's messages alongside OBS indicators to narrow down the cause.
YouTube lists different figures for H.265 and AV1, but those are not automatically the right choice for a low-end PC. A lower bitrate figure is useful only if the computer has an encoder that can produce the selected codec smoothly. Use a codec your installed encoder supports reliably; there is no need to choose a less familiar codec just because its table has a lower number.
Test the complete broadcast before leaving it on
Make a test that resembles the stream you intend to run. Include the real audio path, representative transitions or animated elements, and the final resolution and bitrate. YouTube explicitly advises testing before going live with audio and movement similar to the planned broadcast. A still image on its own may not reveal problems that appear when visual transitions begin or when other applications start using the PC.
During the test, check that OBS is not accumulating encoding or rendering problems and that YouTube's stream health remains acceptable. Listen for missing, distorted or out-of-sync audio. YouTube's published guidance specifies AAC or MP3 audio, stereo at 128 Kbps and a 44.1 kHz sample rate for stereo. Use the options supported by your encoder and confirm the result in the stream rather than assuming a selected setting guarantees correct playback.
If the test is unstable, identify the symptom before lowering everything. Encoding lag suggests you should simplify the visual scene, close unnecessary applications, or test a lower output such as 480p30. Dropped frames caused by network conditions call for a bitrate and connection check. If the audio is missing, investigate the audio source and OBS mixer rather than the video resolution. Keep a note of the settings that worked so an update or an accidental change does not leave you guessing before the next broadcast.
For overnight operation, think beyond the preview window. Check that the machine does not sleep, that power settings will not interrupt the session, and that you know how you will monitor stream health. If you need to keep your own computer off, StreamNeo removes the need to leave that PC running by taking an uploaded video and running it as a YouTube live stream; it does not change YouTube's encoder recommendations or remove the need to prepare the file and channel correctly.
If the same stream later buffers from a file source, distinguish that from an OBS encoding issue: storage or playback can be another part of the chain. The checks in this guide to NAS disk-read buffering are relevant when a playlist is being read from network storage, while the bitrate troubleshooting checklist is more relevant when YouTube specifically flags a low incoming bitrate. Keep the diagnosis tied to the message you see instead of changing several settings at once.

Once your stream has enough runtime to review, YouTube Analytics for live streams can help you look at performance after the broadcast; it does not replace checking stream health while you are live.

FAQ
Is 720p30 always the best resolution for a bhajan stream?
No. It is a practical first setting for low-motion content, provided your PC can encode it and your upload connection can sustain it. Test it with your real audio and visuals; use 480p30 if the test shows instability.
Does YouTube set a different keyframe interval for India?
The YouTube guidance cited here is platform-wide, not India-specific. Set the interval to two seconds, and do not exceed YouTube's stated four-second maximum.
Should I enter 60 or 2 in OBS for a two-second interval?
OBS commonly presents Keyframe Interval in seconds, so enter 2. The equivalent at 30 fps is 60 frames, which matters only if the encoder's control asks for frames.
Is YouTube's minimum bitrate enough for nonstop streaming?
The minimum is not a stability guarantee. Test the sustained upload connection and the stream itself, then choose a bitrate and resolution that remain reliable in your conditions.
