To send a YouTube live stream in 4K at 60 frames per second, configure your encoder to output 3840×2160 at 60fps. YouTube normally detects the encoder’s resolution and frame rate automatically. If you need to select them manually, create a custom stream key in YouTube Studio and enable Turn on manual settings under Stream Resolution. The manual setting does not turn lower-resolution video into 4K.
Set the stream resolution in YouTube Live Control Room
- Open Live Control Room. In YouTube Studio, select Create → Go Live.
- Open the Stream tab to manage the stream and its key.
- Choose automatic or manual resolution. YouTube recommends automatic detection by default. If you need to choose the resolution yourself, create a custom stream key and turn on Turn on manual settings under Stream Resolution.
- Configure the encoder. Set its video output to 3840×2160 (2160p), 60fps. YouTube detects what the encoder sends; selecting 4K in Control Room cannot upscale a lower-resolution encoder output.
- Match the encoder settings to YouTube’s guidance. Choose a supported codec and use the corresponding bitrate below. Set a 2-second keyframe interval, do not exceed 4 seconds, and use constant bitrate (CBR).
- Test and monitor. Before the event, test with audio and motion similar to the planned stream. Check the Live Control Room preview, then watch stream health and messages while live.
YouTube’s current English-language encoder guidance lists RTMP/RTMPS, H.264, H.265/HEVC and AV1, with frame rates up to 60fps. The settings below are recommendations from that page, accessed in 2026; the page does not display a publication year.

Choose a 4K60 bitrate by codec
| Codec | YouTube-recommended bitrate for 4K/2160p at 60fps |
|---|---|
| AV1 or H.265/HEVC | 35 Mbps |
| H.264 | 50 Mbps |
These are YouTube’s recommendations, not a guarantee that a particular encoder, device or internet connection can sustain the stream. Test your upload connection and confirm your encoder supports the codec and output you intend to use. YouTube’s guidance does not establish compatibility for specific cameras, capture devices or computers; check their manufacturers’ specifications.

Automatic detection or manual settings?
Use automatic detection when it reports the encoder output correctly
YouTube recommends automatic resolution and frame-rate detection by default. If the encoder is sending 3840×2160 at 60fps and the stream is detected as expected, there is no need to switch to manual selection.
#1 Best Overall
- 4K & HD STREAMING IN H.264 AND H.265 – Self-contained processor supporting H.264 and H.265 encoding in HD or Ultra HD (up to 2160p60) via SRT or RTMP, streaming directly to YouTube, Facebook, X, Twitch, Zoom, Microsoft Teams, OBS, Wowza, and many more — no encoding PC needed.
- 12G-SDI INPUT WITH STANDARDS CONVERSION – Supports input resolutions up to DCI 4K60 with an SDI input and SDI loop output, plus Teranex-powered automatic standards conversion so any HD or Ultra HD source streams cleanly at any target resolution.
- DUAL MONITOR OUTPUTS – Features both SDI and HDMI monitor outputs with a user-configurable standards converter on both the 12G-SDI Out and 4K HDMI Out, so you can feed a confidence monitor or downstream device at any required format independent of your streaming standard.
- ETHERNET + 5G/4G MOBILE WITH AUTO-FAILOVER – Connect via Gigabit Ethernet (10/100/1000BASE-T) or tether a smartphone via USB-C for mobile data, with automatic switchover between connections — ensuring your stream stays on air even if the primary internet connection drops.
- CLOSED CAPTIONS, TIMECODE & REST API – Supports embedding CEA-608 and CEA-708 closed captions in live RTMP streams, source timecode over RTMP and SRT, and offers a REST API over Ethernet for external HTTP control — ideal for broadcast automation and accessibility-compliant workflows.
Use manual settings when you need to specify the stream resolution
Create a custom stream key, then enable Turn on manual settings under Stream Resolution. This controls YouTube’s stream-resolution setting; the encoder must still send actual 4K60 video. Codec choice should depend on encoder support and workflow, as well as the different YouTube bitrate recommendations above—not on a universal codec winner.
Know what the 4K60 setting changes
This setup concerns the resolution and frame rate sent from your encoder to YouTube. Viewer playback quality is separate: YouTube transcodes live streams into multiple output formats for different devices and network conditions, and viewers choose from the qualities available to them.

For 4K/2160p, YouTube’s encoder guidance says low-latency optimization is unavailable and the stream is set to normal latency. The same guidance recommends a 2-second keyframe interval, with a maximum of 4 seconds, and CBR.
Troubleshoot when YouTube does not show 4K60
- The stream appears below 4K: Check the encoder’s actual output resolution. A 4K label or manual Control Room selection does not convert a lower-resolution signal into 3840×2160.
- The stream is not 60fps: Verify the encoder is outputting 60fps and that the source and full signal chain support that rate. YouTube’s listed maximum is up to 60fps; device-specific support must be confirmed with the manufacturer.
- The stream is unstable or shows health warnings: Check that the upload connection can sustain the selected bitrate, then test again with representative audio and motion. Review the Live Control Room preview and stream-health messages.
- You cannot find manual resolution selection: Confirm that you are using a custom stream key and look under Stream Resolution for Turn on manual settings. Automatic detection is the recommended default.
- You expected low latency: YouTube sets 4K/2160 streams to normal latency; low-latency optimization is not available for this resolution.
Do you need a capture card or special encoder?
No special purchase is required just to change the Live Control Room resolution setting. YouTube supports software encoders and standalone hardware encoders. A capture card may be relevant if you need to bring a camera or console signal into a computer, but it is not the Control Room’s resolution toggle; the complete signal chain must support the desired 4K60 output.
