For a straightforward local setup, use OBS Studio to loop your Malayalam video and send it to a YouTube Live encoder stream. Set output to 1280×720, match the frame rate to the video, and for H.264 at 720p30 use YouTube’s 8 Mbps recommendation rather than mistaking its 3 Mbps minimum for the target.
The repeat is controlled by OBS, not by YouTube’s bitrate setting. This guide takes you from preparing the file and stream through a private test, then explains what to check if the stream does not behave as expected.
Prepare the video and YouTube stream
Before opening OBS, identify the exact video file you intend to broadcast and check that it plays correctly on your computer. Confirm that its picture is oriented as intended, its audio is audible, and the file does not end with an unintended blank or silent section. A loop repeats the file as it is; it does not repair an awkward ending or make an audio transition seamless.
You also need permission to rebroadcast the video and its audio. A Malayalam-language recording may include a song, performance, translation, devotional text, or other material with separate rights. Technical guidance cannot establish the rights for your particular file, and a private test does not settle whether the content is suitable for a public stream. Check the applicable rights and YouTube’s current rules for the material you plan to use.
In YouTube Studio, open the Live Control Room and create or schedule an encoder stream. Copy its stream URL and stream key into a secure place you can reach while configuring OBS. YouTube describes stream keys as resembling a password and address for the stream, so do not post the key or show it in a screenshot. If you expose it, replace or reset it in YouTube Studio before using the stream again.
Choose RTMPS when the connection workflow offers it. YouTube’s live encoder settings cover supported ingest settings and protocols. A scheduled or created stream gives OBS a destination; it does not contain the video loop itself. You can leave YouTube’s resolution and frame-rate detection on automatic for a conventional setup. Manual ingest settings are an option when you have a specific reason to fix them, not a requirement for every 720p stream.
Keep the stream unlisted or private for the first test if that suits your channel and test audience. The goal is to exercise the whole path without treating a successful OBS preview as proof that viewers can receive the stream. If you are also planning how to rotate content over time, see how to rotate seasonal videos in an always-on stream; that is a separate content-planning choice from looping one file.
Add the file as an OBS Media Source
Open OBS and create a scene for this broadcast. Give the scene a practical name, such as “Malayalam 720p”, then add a Media Source from the Sources panel. Choose Create New, enter a clear source name, and browse to the local video file. For a single-file loop, Media Source is the direct choice: OBS provides the playback and repeat controls in that source.
In the Media Source properties, enable Loop. If you want the video to start again when the scene becomes active, consider the source’s restart playback option as well; this is useful when you return to the scene after switching away. Property names can vary slightly by OBS version, so use the labels displayed in your installed release. The key point is that the repeat control belongs to the source playing the file.
The OBS Media Sources guide describes the source types and their controls. For one video, use Media Source and its Loop checkbox. For a set of separate files, OBS has a VLC Video source with playlist controls; that route requires VLC to be installed and is better suited to a playlist than to a single file. Do not add several overlapping sources just to repeat one video.
After adding the source, check its fit in the preview. If the source is larger or smaller than the canvas, use the transform menu to fit it appropriately, while preserving the intended aspect ratio. A 16:9 video fills a 1280×720 canvas naturally. A video with a different aspect ratio may have bars or need cropping; decide which appearance is correct for the material rather than stretching the picture.
Play through the beginning and the end once before going live. Check that the source reaches the end and restarts at the beginning, with no unexpected black interval, missing audio, or scene change. If you are combining multiple clips rather than looping a single file, the considerations differ; this explanation of black frames between OBS playlist videos is relevant to that multi-file case.
Enable Loop and set 720p output
In OBS, open Settings → Video. Set Output (Scaled) Resolution to 1280×720 for a 720p output. This is the size OBS sends after scaling; it is distinct from the video’s native dimensions and from the canvas resolution. If the source itself is 720p, setting the output to the same size avoids an unnecessary size change. If the source is larger or smaller, OBS scales it to the chosen output.
The base canvas and scaled output need not always be identical, but a simple one-file setup is easier to reason about when the canvas is also set to 1280×720. This gives you a preview matching the intended output shape. Check the preview after changing resolution, especially if you have already positioned or cropped the source.
The loop remains configured in Media Source; changing output resolution does not change playback behaviour. Likewise, YouTube’s stream settings do not tell OBS to repeat a file. If the video stops after one pass, return to the Media Source properties and verify Loop is enabled. If it repeats but the picture is framed incorrectly, adjust the source transform rather than changing YouTube’s ingest settings.
OBS’s Studio overview explains the basic scene, source, preview and output workflow. The preview is useful for framing but is not a substitute for checking the stream in YouTube’s Live Control Room. Encoding, upload and ingest can introduce problems that are not apparent in the local preview.
Match frame rate to the source
In Settings → Video, choose a Common FPS Value that suits the source. Do not assume that every Malayalam video is 30 fps simply because 720p30 is a common streaming target. Check the file’s properties or inspect it in a video player that reports frame rate, then use an output rate that matches the source when practical.
If your video is 30 fps, set OBS to 30 fps. If it is 25 fps, choosing 25 can avoid unnecessary frame duplication or conversion. A 60 fps output makes sense only if the source has that motion detail and your computer can sustain encoding it. OBS notes that higher frame rates use more system resources; a static devotional image with a slowly moving background is unlikely to benefit from being forced to 60 fps if the original is 30 fps.
Frame rate is an output property, not a language property. Malayalam vocals, lyrics or titles do not dictate the frame rate. The nature of the recording does: source frame rate, motion, and the capability of the computer. YouTube’s current bitrate table lists the same H.264 recommendation for 720p30 and 720p60, so doubling the frame rate does not mean you should assume a different listed bitrate target.
If you must choose between a higher frame rate and a stable encode on a modest machine, favour the source-matched setting the computer can maintain. Watch OBS’s status indicators during a test. Dropped frames caused by encoding load and dropped frames caused by a network problem are different issues; reducing frame rate may help the first but not necessarily the second.
Set bitrate, CBR, and keyframe interval
In Settings → Output, switch Output Mode to Advanced if needed, then open Streaming. Select H.264 as the encoder where available, use CBR rate control, and set the keyframe interval to 2 seconds. YouTube accepts H.264, H.265 and AV1 over RTMP/RTMPS, but H.264 is a broadly supported starting point for an OBS workflow. YouTube says not to exceed a four-second keyframe interval; two seconds is the recommended setting in its guidance.
For H.264, YouTube lists 3 Mbps as the minimum and 8 Mbps as the recommended bitrate for 720p30. Its table gives the same minimum and recommendation for 720p60. The minimum is a floor in YouTube’s guidance, not the value to call recommended. If the video is 720p30 and your upload connection can sustain the rate with headroom, 8 Mbps is the recommended target. If it cannot, first address the connection or choose a lower output demand rather than claiming 3 Mbps is the recommendation.
| 720p output and codec | YouTube-listed minimum | YouTube-listed recommendation |
|---|---|---|
| 30 fps, H.264 | 3 Mbps | 8 Mbps |
| 60 fps, H.264 | 3 Mbps | 8 Mbps |
| 30 or 60 fps, AV1 or H.265 | 2 Mbps | 6 Mbps |
These are YouTube’s published encoder figures, not measurements of your connection. The official live encoder settings page does not display a publication year for the figures, so this guide does not assign one. Choose a codec your OBS installation and computer support reliably. A theoretical bitrate setting is not useful if the encoder cannot maintain it or the upload connection cannot deliver it.
Leave capacity for audio and ordinary network variation rather than using all of your available upload bandwidth for video. YouTube recommends leaving 20% bandwidth headroom when checking the connection. Its 720p recommendation refers to the video bitrate; it is not permission to saturate the entire upstream connection. For stereo audio, YouTube lists AAC or MP3 and recommends 128 Kbps at 44.1 kHz. Confirm OBS’s audio settings and listen for clipping, silence or a mismatch between picture and sound.
For a deeper explanation of rate control and keyframes, use the encoder settings guide for CBR and keyframes. The practical starting point remains CBR, two-second keyframes and a bitrate your measured connection can sustain. If you need to estimate a different always-on operating approach, the cloud egress cost guide discusses a separate cost question; it does not change YouTube’s encoder settings.
Connect OBS and test the full path
In OBS, open Settings → Stream and select YouTube as the service if it is offered. Paste the stream key from the stream you created in YouTube Studio. If OBS asks for a server or stream URL instead, copy the URL from the same YouTube stream page. Avoid mixing a URL from one scheduled stream with a key from another. Keep the key private, as you would a password.
Apply the settings and start streaming only when you are ready to run a test. Check the Live Control Room for the incoming preview and stream status. Confirm the expected resolution and frame rate, then verify that audio reaches YouTube, not just the OBS monitoring output. Watch long enough to see the video reach its end and restart. A stream that looks correct for the first minute may still fail at the loop transition or later under sustained encoding and upload load.
YouTube recommends testing with similar movement and audio to what you intend to broadcast. For a looped Malayalam programme, test the actual file, including its loudest music or speech and its end-to-start transition. Keep the test private or unlisted where appropriate, and ask a second person to view it on another device or connection if you need to check the viewer experience. That can reveal a muted audio track, incorrect crop or playback buffering that is not obvious in the encoder preview.
The first test should exercise the same computer, network connection, OBS scene and bitrate you plan to use. Do not infer reliability from a short local preview. YouTube’s streaming tips advise checking upload bandwidth and allowing headroom. The recommendations on timing for scheduled events are useful even for a planned long stream: configure the encoder well in advance and allow time before the public start to detect issues.
If the stream does not appear, recheck that the correct stream key and URL are paired, the stream is active in the Live Control Room, and OBS is actually sending. If the picture appears but buffers, check upload stability and bitrate before changing unrelated source settings. If the stream is smooth but the file does not repeat, troubleshoot the Media Source Loop property. This separates ingest, network and playback problems instead of changing several settings at once.
Monitor stream health during a long run
Once the test passes, keep an eye on both OBS and YouTube’s stream health. OBS can report dropped frames or encoding lag; YouTube’s Live Control Room can show ingest warnings and viewer-side status. Note when an issue occurs and which indicator changes. Network drops call for a connection check, while encoder overload points towards reducing system load or output complexity.
A local OBS workflow depends on the computer remaining on, OBS staying open, and the network connection remaining available. Disable sleep or automatic restart behaviour that would interrupt the session, and make sure the machine has adequate power and cooling. A long stream is not just a successful start button press; it is a process to test and monitor. Avoid treating one clean hour as a guarantee that a future overnight run will be uninterrupted.
If you need the channel to continue while your own computer is switched off, that changes the operating model: you would use a cloud streaming workflow rather than a locally running OBS session. In that specific case, StreamNeo removes the need to leave your computer running by taking the uploaded file and channel connection into a 24/7 broadcast workflow. It is YouTube-only, so keep the distinction clear: OBS is the direct local process described here, while a cloud option addresses the inconvenience of maintaining your own computer and connection.
Whichever approach you use, retain a known-good copy of the source file and stream configuration, but do not store an exposed stream key in a place other people can access. Check the current official YouTube guidance when changing ingest settings, since available options and recommendations may be updated. If you want to understand what happens after a stream has been running, the analytics metrics guide explains which channel measurements are useful without confusing them with encoder health.

FAQ
Does YouTube repeat my video when I set a bitrate?
No. Bitrate controls the rate at which OBS sends encoded video, not whether the file repeats. Enable Loop in the OBS Media Source properties to restart one file after playback ends.
Is 3 Mbps the recommended bitrate for 720p30 H.264?
No. YouTube lists 3 Mbps as the minimum and 8 Mbps as the recommendation for 720p30 H.264. Use the recommended rate if your connection can sustain it while leaving upload headroom.
Should every Malayalam video be streamed at 30 fps?
No. Choose an output frame rate based on the file’s actual frame rate and the motion it contains. Thirty fps is a common setting, not a property of Malayalam-language video.
Can OBS keep streaming if I switch off the computer?
No. A local OBS broadcast depends on the computer and its internet connection remaining available. To stream with the computer off, use a cloud workflow designed for continuous broadcasting, and test that workflow separately before relying on it.
