A local video can loop continuously in OBS and be sent to a YouTube Live broadcast, but looping the file does not by itself make the stream reliable. For 4K at 60 frames per second, you also need a suitable encoder, a sustained outbound connection, the correct YouTube settings, and a complete test before publishing.
The practical route is to add the file as an OBS Media Source, turn on Loop, connect OBS to the stream URL and key from YouTube Studio, then check the preview and stream health. India does not require a special OBS configuration for this workflow; the important measurement is the upload performance at the location where the computer will run.
Prepare the 4K60 video source
Start with the file you intend to repeat. For a 4K60 broadcast, the useful target is a video whose picture is 3840 × 2160 and whose frame rate is 60 fps. If the source is smaller or uses a different frame rate, OBS can still play it, but changing the output settings does not create additional detail or motion information in the original file.
Check the file from beginning to end before adding it to OBS. Watch for a black frame at the end, a sudden audio change, an incorrect aspect ratio, or a short section that was accidentally left in the edit. These defects become more noticeable when the same clip repeats throughout an always-on channel. For a devotional loop, for example, listen specifically to the transition between the final chant and the opening audio rather than checking only the first minute.
Keep the file in a location that will remain available while OBS is running. A local file on the computer is enough. OBS supports common local video formats, including MP4, MOV, MKV and WebM, as described in its Media Sources documentation. An external drive is not required, although it can be useful when the source is too large for the computer’s internal storage. It does not improve the YouTube connection or picture quality by itself.
Storage space is only one part of preparation. Decoding 4K60 video can place a substantial load on the computer, especially if the file uses a codec that the machine cannot decode efficiently. Close unrelated applications, disable sleep, and set the computer so that it will not restart for an update during the planned broadcast. These are operating precautions, not guarantees that the machine will run without interruption.
If your channel will eventually rotate several clips, decide whether one file is really the right source design. A single Media Source is the simplest choice for one repeating video. For several files, a playlist-based arrangement may be more suitable. The continuous YouTube playlist guide covers the planning side, but the single-file method below is the direct way to loop one local video.
Before opening OBS, also confirm that the channel can stream. YouTube’s live-streaming eligibility guidance says the channel must be verified and must not have live-streaming restrictions in the relevant previous period. It also states a minimum age requirement for streaming. Check the current YouTube page rather than relying on an old account setting or a tutorial recorded for a previous interface.
Add the file as an OBS Media Source
Open OBS and create a scene for this broadcast, or select the scene that should carry the video. In the Sources panel, choose Add, then Media Source. Give it a clear name such as 4K60 main loop, so it is easy to identify if you later add a logo, text layer, or separate audio source.
In the Media Source properties, select the local video file. Leave the source visible in the scene and confirm that the preview shows the expected picture. If the image is cropped, open the source’s transform controls and check the canvas relationship before changing the video settings. A 16:9 4K file should normally fit a 16:9 canvas without cropping, but a vertical or unusually framed source needs a deliberate choice rather than an automatic stretch.
The setting that matters for one repeating file is Loop. Enable it, apply the property, and let the clip reach its end during a test. Do not treat a source appearing in the preview as proof that looping works. The end-of-file event is where a missing loop setting, a file-read problem, or a visible pause will show itself.
You may also see the option Restart playback when source becomes active. This is separate from Loop. Restart playback controls what happens when the source enters the visible current scene, while Loop controls whether the file starts again after reaching its end. If you hide and show the source while preparing the scene, the restart option can affect where playback begins, but it does not replace the Loop setting.
Check the source properties again after applying them. OBS can remember the file path and the selected options, but a path can become invalid if you move or rename the video. Avoid making last-minute file changes after your final test. If you need to replace the content, repeat the test from the beginning, including the loop point.
For a playlist rather than one file, OBS also offers a VLC Video source with playlist controls, provided VLC is installed. That is a different workflow and adds another dependency. A single Media Source is easier to inspect when your requirement is one local 4K60 clip repeating continuously.
Enable Loop and check the audio transition
Play the source in OBS and watch the audio mixer while it runs. Confirm that the intended audio source is active, that the mixer meter moves without remaining pinned at the top, and that the sound is not being duplicated by a second capture source. If the video file already contains audio, adding another copy of the same soundtrack can create an echo or excessive level.
Let the file reach the loop point at least once before you connect to YouTube. Observe the last few seconds and the first few seconds after the restart. A loop can be technically working while still producing an audible click, a gap, or a sudden change in volume. If the edit has no clean transition, fix the source file rather than trying to hide the problem with a stream setting.
Check the audio channels and the monitoring arrangement carefully. You want the broadcast mix to contain the intended sound, but you do not necessarily want to monitor it through speakers while a microphone or desktop capture is also active. Headphones can help you identify a repeated signal, but monitoring through the computer is not a substitute for listening to the actual YouTube preview.
A quiet or absent meter may indicate that the file has no audio track, the source is muted, or the audio is routed somewhere other than the broadcast mix. A meter that is constantly at the top suggests clipping risk. OBS controls can change the local mixer, but they cannot restore audio that was never present in the file. Return to the source properties and the audio mixer before changing YouTube settings.
If the channel is for music, meditation, temple bells, or a study ambience loop, content rights and channel policy still matter. A technically clean stream can be interrupted or restricted if the underlying material is not yours to broadcast. For a channel focused on temple audio, compare the content workflow described in this guide to a 24/7 temple bells channel, and check YouTube’s current policies independently.
Connect OBS to the YouTube broadcast
In YouTube Studio, open the Live Control Room and create or select the intended broadcast. YouTube supplies an ingest server or stream URL and a stream key for the encoder. The key functions like a password, so do not paste it into a public screenshot, share it in a support forum, or store it in a document that other people can access.
In OBS, open Settings and go to Stream. Choose the YouTube service if it is available in your version, or enter the supplied server details according to the current OBS interface. Use the stream URL and key from the broadcast you actually intend to run. A key copied from another event can send the signal to the wrong control room or leave you wondering why the expected preview remains empty.
Use RTMPS where the YouTube workflow offers it. YouTube recommends RTMPS for encoder ingest and describes it as encrypting the data transfer. Its current encoder guidance is the right place to confirm the server, protocol, and other settings because the Studio interface can change.
Do not start the public event merely because OBS says it is connected. Sending an encoder feed and making the event visible are separate decisions in YouTube Studio. For the first run, an unlisted or private test can let you inspect the feed without directing viewers to an unfinished broadcast. Confirm which visibility setting is selected before you click the final start controls.
A useful separation is to prepare the YouTube event first, connect OBS second, and publish only after the preview is correct. This makes it easier to identify whether a problem is in the local source, the encoder connection, or the YouTube event configuration. If live streaming is unavailable at the account level, follow the fix order in this guide to YouTube’s live-streaming availability errors rather than changing random OBS settings.
Choose codec, bitrate and ingest settings
The codec and bitrate must be considered together. YouTube publishes separate 4K/2160p at 60 fps figures for different codec families. Its encoder-settings page lists 35 Mbps as the recommended bitrate for AV1 or H.265, with 10 Mbps as the published minimum, and 50 Mbps as the recommended bitrate for H.264, with 14 Mbps as the published minimum. These figures are YouTube’s ingest guidance, not a promise that your broadband connection will sustain them.
| Encoder choice | YouTube 4K/60 published minimum | YouTube 4K/60 published recommendation | What to check locally |
|---|---|---|---|
| AV1 or H.265 | 10 Mbps | 35 Mbps | Hardware support, encoder load, and stable upload capacity |
| H.264 | 14 Mbps | 50 Mbps | Hardware support, encoder load, and stable upload capacity |
The labels in this table matter. Do not take the 35 Mbps figure from AV1 or H.265 and apply it to H.264, or take the H.264 recommendation and describe it as a universal 4K number. Choose a codec your computer can encode reliably and that the current YouTube ingest guidance supports. A theoretically efficient codec is not useful if the encoder load causes skipped frames or overheating.
Set the output resolution to 3840 × 2160 and the frame rate to 60 only when the source, encoder, computer, and connection can work together at that level. In OBS, check both the base canvas and the scaled output. The exact names and locations of settings can vary by OBS version, but the result should be a progressive 4K60 output rather than a 4K canvas carrying a lower-quality source.
For the ingest properties, YouTube recommends constant bitrate, or CBR, and a keyframe interval of two seconds. Its guidance says not to exceed four seconds. It also lists progressive scan, square pixels, and up to 60 fps. For SDR material, it lists Rec. 709 and 8-bit. Use the current official YouTube encoder settings and bitrates page when checking these values.
Measure upload performance on the actual connection and at the time and place where the stream will run. An advertised download speed is not an upload test, and a short speed-test result is not proof of a sustained overnight connection. Test over the same network path you plan to use, preferably with the computer in its final position and with other heavy uploads stopped.
There is no responsible India-wide bitrate setting. A fibre connection in one building, a shared apartment network, a mobile hotspot, and a connection affected by evening congestion can behave differently. Leave headroom rather than selecting a bitrate that sits at the edge of a brief speed-test result. If the connection cannot sustain the chosen 4K setting reliably, reduce the output resolution or frame rate and retest. A stable lower-resolution stream is more useful than an unstable 4K claim.
At 2160p, YouTube’s published guidance says low-latency mode is unavailable and the stream uses normal latency. That affects how quickly viewers see the broadcast, not whether the Media Source loops. Do not try to solve a 4K latency limitation by changing the local playback source.
Test the complete loop and preview
The most useful test includes every part of the path: the source file, OBS playback, encoder settings, upload connection, YouTube preview, and the loop transition. Testing only inside OBS can miss dropped frames, upload instability, audio changes introduced during ingest, or a mismatch between the selected event and the stream key.
Create the test broadcast in YouTube Studio and choose private or unlisted visibility when that suits the channel plan. Start the OBS output, then wait for the Live Control Room to receive the signal. Check the preview for the correct picture, the correct framing, the expected motion, and the expected audio. Do not promote the event while the preview is still blank or showing an old feed.
Let the file complete one full cycle during the test. If the video is long, plan enough time to reach the end rather than assuming the setting will work. At the loop point, check whether the first frame appears immediately, whether the audio restarts cleanly, and whether the YouTube preview continues without a visible interruption. The local OBS preview and YouTube’s received preview should both be inspected.
Open the stream health indicators in the Live Control Room. Look for warnings about bitrate, dropped frames, connection quality, audio, or video. A clean beginning does not prove that the connection will remain clean later, so keep the test running while you observe whether the health state changes.
Test the conditions that will exist during the real broadcast. If the computer normally shares the connection with a shop, household, camera upload, or cloud backup, either pause those activities or test with them present. If the channel is intended to run overnight, a short test cannot reveal every long-running issue, but it can still expose a wrong key, an incorrect codec, a loop failure, or a connection that is already unstable.
Write down the settings that passed the test. Record the source file path, resolution, frame rate, codec, bitrate, keyframe interval, visibility choice, and the date of the test. This gives you a recovery reference when a later change produces a blank preview or a stream-health warning. Do not record the private stream key in a shared checklist.
Monitor stream health and connection
Once the stream is public, continue checking YouTube’s stream health rather than relying only on the OBS status bar. OBS can report that it is sending data while YouTube is receiving an unstable or incomplete feed. YouTube’s live-streaming tips recommend testing and monitoring audio, video quality, and stream health.
Watch for dropped frames and encoding lag in OBS. These point to different classes of trouble. A connection problem can prevent the encoded data from reaching YouTube, while encoding overload can occur even when the network is fine. High processor or graphics load may require a codec change, a lower output, fewer scene effects, or a different hardware encoder. Do not respond to every warning by raising the bitrate.
For network problems, check the upload path rather than just the router’s advertised plan. Wi-Fi interference, a congested shared connection, a failing cable, or another device uploading large files can affect the stream. If practical, use a wired connection for the streaming computer and stop competing uploads. If the issue persists, retest at a lower output setting and compare the stream health.
Have a restart plan. Keep the source file available, keep the stream key private, and know which YouTube event should receive the feed. If the connection drops, first identify whether OBS has stopped encoding, the local network has failed, or YouTube has disconnected the ingest. Restarting without checking can leave two encoder sessions or send the feed to the wrong event.
For an always-on channel, the computer also needs practical care. Disable sleep, keep ventilation clear, check available storage for recordings or logs, and avoid unnecessary software updates during the broadcast window. If the channel must continue while your computer is switched off, StreamNeo removes the need to keep this local OBS machine running by taking an uploaded video, the YouTube stream key, and the continuous broadcast into one cloud-based workflow with automatic monitoring and restart; it is YouTube-only, so it does not replace the OBS method when you need live scene control.
You can also compare the operational trade-offs in this guide to cloud platforms for a 24/7 YouTube stream in India. The relevant question is not which method sounds most automatic, but whether the method matches your need for local control, a fixed file loop, monitoring, and recovery when the connection or computer behaves differently from the plan.

FAQ
How do I make a video loop in OBS?
Add the local file as a Media Source, select the video, and enable Loop in the source properties. Restart playback when source becomes active is a separate option and does not replace Loop. Test the source through the end of the file before sending it to YouTube.
What upload speed do I need for 4K 60 fps YouTube Live?
YouTube lists 35 Mbps as the recommended 4K60 bitrate for AV1 or H.265 and 50 Mbps for H.264, with different published minimums for those codec groups. These are ingest settings, not a guaranteed broadband requirement. Measure sustained upload on the actual streaming connection and leave headroom for variation.
Should I use H.264, AV1 or H.265 in OBS?
Use a codec supported by both your computer and the current YouTube ingest guidance, then compare encoder load with the upload capacity you have measured. AV1 or H.265 has a different published 4K60 bitrate recommendation from H.264, so do not mix the figures. If the computer struggles or the connection is unstable, lower the output and retest.
Can I use low latency for a 4K YouTube stream?
YouTube’s encoder guidance says 2160p streams use normal latency and do not offer the low-latency option. This is a YouTube delivery setting, not an OBS Media Source setting. It does not affect whether the local file repeats.
