YouTube Help’s English encoder table recommends 50 Mbps for H.264 or 35 Mbps for AV1/H.265 at 4K/2160p and 60 fps; YouTube also recommends about 20% upload headroom. Those are platform ingest recommendations, not guarantees that a particular PC or Indian ISP can deliver a stable stream.
The current India-localized guidance may not show the same bitrate table as YouTube’s English page. Check the options and limits in your current YouTube Live Control Room before settling on a bitrate. This guide covers the setup decisions and workflow for a prerecorded video loop from a Windows PC, while distinguishing verified YouTube requirements from OBS interface details that should be checked against the version you install.

Check your PC and upload connection first
A 4K60 loop depends on the weakest part of the chain: the source video, OBS output, encoder hardware, PC, router and available upload bandwidth. A fast download result does not establish that the upload side can carry a live stream. YouTube says, “Have enough bandwidth: The total bitrate you’re streaming cannot exceed the amount of upload bandwidth available.” It also notes that other people using the same connection can reduce the bandwidth available to your computer. See YouTube’s streaming tips.
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
- Measure upload speed, then test stability under the conditions in which the stream will run. Do not treat a single speed-test result as a guarantee.
- Leave roughly 20% upload headroom, as YouTube recommends. As a planning example, a 50 Mbps video bitrate requires more than 50 Mbps of stable usable upload before accounting for audio or other outgoing traffic. This is arithmetic from the recommendation, not an India-specific ISP threshold.
- Account for other devices, cloud backups, uploads and any second stream sharing the connection.
- Use wired Ethernet if your PC and router support it and a suitable cable is available. A cable can reduce reliance on Wi-Fi, but it cannot create bandwidth or cure an unstable ISP connection.
4K60 encoding also places a substantial load on the computer. Check that OBS offers an encoder your hardware can use at the intended resolution and frame rate, and run a realistic test before scheduling a public stream. YouTube’s bitrate guidance describes what it recommends sending to its ingest service; it does not certify your PC’s encoding capacity.

Choose a codec and bitrate using YouTube’s current settings
YouTube Help’s English encoder table, accessed in 2026 (the page does not show a publication year), gives the following 4K/2160p, 60 fps figures. YouTube search results have also surfaced a differing table on an Indonesia-language page, so do not assume that every localized page displays identical values. For a stream being configured in India, confirm the current accepted settings in Live Control Room rather than treating the English figures as a rigid India-specific recipe. See YouTube’s encoder settings and bitrate guidance.
| Codec | Minimum bitrate shown | Recommended bitrate shown | What to consider |
|---|---|---|---|
| H.264 | 14 Mbps | 50 Mbps | A familiar ingest option, but the recommended 4K60 bitrate requires a strong, stable upload connection. |
| AV1 or H.265/HEVC | 10 Mbps | 35 Mbps | The table shows a lower recommended bitrate than H.264, but your encoder must support the format and YouTube must offer it for your stream. |
Do not select AV1 or HEVC solely because its recommended number is lower. Check what your hardware encoder can produce reliably, what OBS exposes on your system, and what YouTube currently accepts in Live Control Room. Encoder choices and available presets depend on your installed OBS version and hardware; YouTube’s platform table is not a recommendation for a particular GPU preset.
Set the YouTube ingest targets
YouTube’s live-encoder guidance specifies RTMP or RTMPS, H.264, H.265/HEVC or AV1 (where supported), frame rates up to 60 fps, constant bitrate (CBR), and a recommended two-second keyframe interval that must not exceed four seconds. YouTube recommends RTMPS because it encrypts the transfer. For standard dynamic range (SDR), its guidance calls for Rec. 709 color and 8-bit depth, progressive scan and square pixels. For stereo audio over RTMP/RTMPS, YouTube lists AAC or MP3 and recommends 44.1 kHz and 128 kbps stereo audio. Consult the current YouTube encoder settings page and match the available OBS controls to the accepted values shown for your stream.

These are ingest and output targets, not promises about specific OBS labels or encoder presets. The exact controls exposed on a Windows PC vary with OBS version and hardware. Follow current OBS documentation for the installed version rather than assuming a particular menu path or that every listed codec is available.
Prepare the prerecorded video and loop workflow
The intended workflow is to add the recording as a media source in OBS, configure that source to repeat, confirm that its audio is routed as intended, set the output to the chosen 4K60 targets, then send the stream to YouTube. The exact Windows click path and loop-control label can vary by OBS version; consult the current OBS documentation for the version you use. Test the actual file and container rather than assuming every video will loop cleanly.
- Check the source file. Confirm its resolution, frame rate, picture orientation and audio. A 4K60 output cannot add detail or motion absent from a lower-resolution or lower-frame-rate recording.
- Add the video in OBS. Use the media-source workflow documented for your OBS version and select the file you intend to play.
- Enable repeat for the source. Find the current loop or repeat control in that version’s media-source settings. Do not rely on an unverified control name; confirm that playback restarts at the end of the file.
- Check audio routing. Listen to the source in the OBS preview and confirm that the intended audio reaches the stream mix. Check for silence, clipping or an abrupt change at the loop boundary.
- Set the output format. Match resolution, frame rate, codec, bitrate, CBR and keyframe interval to what your encoder supports and YouTube currently accepts. Apply YouTube’s SDR color guidance unless you are intentionally preparing an HDR stream.
- Connect to YouTube. In Live Control Room, obtain the stream URL and stream key for the encoder. Enter them in the appropriate OBS streaming settings according to the current OBS instructions. Treat the key like a password: never publish it or show it in screenshots. YouTube says a custom stream key can be reused; see its stream settings guidance.
Because this guide does not establish the exact OBS controls for a given Windows release or validate a particular file/container, verify the current interface and test the file on your own system. Do not assume that setting a loop option alone proves that a long-running stream will remain live indefinitely.

Run an unlisted rehearsal before going public
Use YouTube’s preview and a realistic rehearsal to catch problems before viewers rely on the stream. Make the test representative: include the same audio and motion as the planned loop, and let playback cross at least one end-to-start boundary. YouTube advises testing with representative audio and motion, reviewing stream-health messages, checking the Live Control Room preview and monitoring audio and video. Its encoder guidance and live-streaming tips also support advance setup and checking that the event can be viewed on the channel or watch page and on mobile.
- Confirm that the preview appears and that picture and audio are present.
- Watch the end of the video and the start of the next loop for a pause, missing frames, silence or a level change.
- Review YouTube’s stream-health messages and OBS’s available output or dropped-frame indicators; investigate issues rather than assuming the stream is healthy because the preview is visible.
- Open the event from its watch page or channel on another device, including a phone, and check playback there.
- Repeat the test after changing the file, encoder, bitrate, network path or relevant output settings.
Plan latency and decide whether HDR is appropriate
Latency at 4K
YouTube says its low-latency improvement option is unavailable at 4K/2160p; 4K streams are optimized for quality with normal latency. If near-real-time interaction matters more than 4K resolution, reconsider the resolution and latency trade-off in Live Control Room. YouTube describes latency as a trade-off between delay and possible buffering in its stream settings guidance.
SDR or HDR
The 4K title does not mean the source is HDR. SDR is the simpler default, with YouTube’s Rec. 709 and 8-bit recommendations. HDR requires a compatible HDR source and a supported hardware HEVC encoder. YouTube’s OBS HDR instructions specify OBS 30.1 or later, Main 10, P010 and Rec. 2100 PQ or HLG, in addition to the compatible source and encoder. Use those settings only for an HDR workflow and verify compatibility in the current YouTube HDR streaming instructions.

Preflight checklist for a continuous stream
- The source video plays correctly and has the picture and audio you intend to broadcast.
- The chosen codec is available on your hardware and accepted by YouTube for the stream.
- The output is configured for the intended resolution and frame rate, with CBR and a two-second keyframe interval (never over four seconds).
- The bitrate fits the upload capacity you have actually tested, with roughly 20% headroom and allowance for shared network traffic.
- The stream key is private, and the encoder connects to the intended YouTube event.
- The rehearsal crossed a loop boundary; picture, audio, stream health and viewer playback were checked.
- You have a plan to notice a disconnect or deteriorating stream health. Testing does not guarantee uninterrupted uptime.
Troubleshoot common 4K60 loop problems
| Symptom | Possible cause | What to check |
|---|---|---|
| YouTube reports poor stream health or the picture buffers | Outgoing bitrate exceeds stable upload capacity, or the connection is fluctuating or shared. | Check upload stability and stream-health messages; reduce bitrate or choose a lower resolution/frame rate that the connection can sustain, then rehearse again. |
| OBS cannot offer the chosen codec or output combination | The encoder or installed hardware may not support that format or configuration. | Choose a codec available on the system and accepted by YouTube. Do not assume the platform’s codec list means your PC supports every option. |
| Video looks soft or motion is uneven | The source may be below 4K60, or the PC, encoder or bitrate may not sustain the selected output. | Check the source properties and encoder performance. Test a lower output target if necessary instead of treating the 4K60 label as proof of source quality. |
| Playback stops or pauses at the loop boundary | The source repeat setting, file/container behavior or system load may be involved. | Verify the current OBS media-source repeat control and test the actual file across multiple boundaries before relying on it. |
| Picture works but audio is missing or changes at the restart | Source audio may not be routed as intended, or the file may have a discontinuity at its boundary. | Listen to the OBS preview and the YouTube rehearsal, inspect the source audio path and test the boundary again. |
| OBS is connected but viewers cannot find or play the event | The event may not be configured or visible as intended, or the wrong event/key may be in use. | Check the selected YouTube event in Live Control Room, inspect its preview and visibility, and open the watch page from another device. |
| Stream key is rejected or the encoder does not connect | The key or stream destination may not match the event, or credentials may have been changed. | Copy the current stream URL and key from the intended Live Control Room event into OBS using its current instructions. Keep the key private. |
Keep the content eligible for YouTube Live
Technical setup does not grant rights to the video or its music. Use content you own or are authorized to stream, and review YouTube’s applicable copyright and live-stream policies before broadcasting. A loop that runs for many hours does not itself establish that the content is original or eligible for monetization; repetitive or reused material may raise separate policy questions. Check YouTube’s current rules for your channel and content rather than relying on the stream remaining online as evidence of compliance.
