For YouTube Live at 4K/2160p and 60 fps, start with NVIDIA NVENC, CBR, and the bitrate YouTube recommends for the codec your software actually exposes: 35 Mbps for AV1 or HEVC, or 50 Mbps for H.264. The RTX 4060 supports AV1 encoding, but that capability does not guarantee the option appears in every encoder or stream setup, or that a particular PC can sustain 4K60 under load.
Treat this as a configuration to test, not a promise of performance. YouTube's figures describe its live ingest recommendations; they are not a benchmark of the graphics card. Test the complete path with representative motion and audio before relying on it for a long broadcast.
A sensible RTX 4060 starting point
For an SDR stream, begin with the settings in this table, then confirm the codec and values in your broadcasting software. YouTube's live encoder settings guidance is the primary reference for ingest settings. NVIDIA's RTX 4060 specifications identify the card's encoder generation and AV1 encode support.
| Setting | Starting point | What to check |
|---|---|---|
| Output resolution and frame rate | 3840 × 2160 at 60 fps | Confirm the software is sending the intended output, not just capturing a 4K source. |
| Encoder | NVIDIA NVENC | The RTX 4060 specification lists one eighth-generation NVENC encoder. |
| Codec | AV1 for SDR, if available; otherwise HEVC or H.264 | Select only a codec supported by the software and YouTube ingest path you are using. |
| Video bitrate | 35 Mbps for AV1 or HEVC; 50 Mbps for H.264 | These are YouTube's codec-specific 4K60 recommendations. |
| Rate control | CBR | Set the target bitrate as a constant rate, where the software offers that control. |
| Keyframe interval | 2 seconds | YouTube recommends two seconds and says not to exceed four seconds. |
| Protocol | RTMPS | YouTube recommends RTMPS for the connection. |
| Stereo audio | AAC or MP3, 44.1 kHz, 128 kbps | Confirm your selected audio codec and output format. |
| SDR colour | Rec. 709, 8-bit | Use this for a conventional SDR stream. |
This is a starting configuration, not a guarantee that the system can encode, capture, render a game, and transmit at these settings at the same time. The RTX 4060 has the relevant hardware capability, but results still depend on the rest of the PC, the workload, the software path, and network conditions. If a test is unstable, lowering output resolution or frame rate may be more useful than raising bitrate.
Choose a codec your setup actually offers
Codec selection is practical rather than theoretical: the software must offer the encoder, YouTube must accept that ingest path, and the codec must suit your output. NVIDIA lists AV1 encode support for the RTX 4060. That confirms a hardware capability; it does not mean every app version, setting combination, or YouTube connection workflow will show AV1 as a selectable option.
For an SDR stream, AV1 is a reasonable first choice if it appears in the encoder settings and your intended YouTube setup supports it. If it is missing, do not spend the whole setup session looking for a hidden switch. Check that the application and drivers are current, verify the chosen encoder mode, and then choose HEVC or H.264 if those are available and accepted in your path.
HEVC is also called H.265. It has the same 4K60 bitrate recommendation as AV1 in YouTube's guidance, and YouTube's listed HDR guidance points to HEVC. H.264 is the alternative to consider when it is the codec your software or ingest route supports. The guidance does not establish a universal quality winner for your specific scene, encoder settings, or PC.
| Codec | YouTube 4K60 video bitrate guidance | HDR note in YouTube's guidance | Selection check |
|---|---|---|---|
| AV1 | 35 Mbps | AV1 is not listed as supported for HDR in this guidance | Use when the software and stream path expose AV1 ingest; suitable starting point for SDR. |
| HEVC / H.265 | 35 Mbps | YouTube's HDR guidance recommends H.265 | Consider for HDR only when the full software and ingest path supports the required format. |
| H.264 | 50 Mbps | Not the codec identified in the cited HDR recommendation | Use when it is the available, supported choice; allow for its higher recommended bitrate. |
The most important selection mistake is choosing a bitrate before confirming the codec. A 35 Mbps value belongs to the AV1 or HEVC recommendation here, while YouTube lists 50 Mbps for H.264 at 4K60. Write down the codec beside the bitrate in your preset notes so that a later software change does not leave you using the wrong target.
AV1 and HEVC: YouTube's 4K60 bitrate guidance
For AV1 or HEVC at 4K/2160p and 60 fps, use 35 Mbps as the YouTube-recommended video bitrate starting point. It is an ingest recommendation, not evidence that an RTX 4060 will hold the workload or that the picture will have a particular quality. The encoder and the content matter, and you should judge the result using the actual scenes you intend to show.
A 35 Mbps video stream also needs headroom beyond the video number. Audio consumes bandwidth, RTMPS traffic adds overhead, and other people or devices may use the same connection. NVIDIA's broadcasting guide suggests keeping the stream near 75% of measured upload capacity to leave room for the game and other programmes. Applying that rule of thumb gives roughly 47 Mbps of measured upload for a 35 Mbps video stream; this is a derived planning figure, not a YouTube requirement or a stability guarantee.
Measure upload under the conditions you expect during the broadcast, rather than relying only on a quiet-time result. A wired connection can remove some avoidable variation from a local Wi-Fi link, though it cannot solve congestion elsewhere on the connection. If the available upload is shared with video calls, cloud backups, or other streams, account for those uses before committing to a 4K60 target.
For HDR, follow YouTube's stated codec guidance rather than assuming that AV1 support on the GPU covers every colour mode. The listed guidance recommends H.265 for HDR and says AV1 is not supported for HDR. If HDR is not an explicit requirement, SDR with Rec. 709 is a simpler baseline for checking that the rest of the stream path works.
H.264: YouTube's 4K60 bitrate guidance
YouTube recommends 50 Mbps for H.264 at 4K60, compared with 35 Mbps for AV1 or HEVC. That difference is a reason to check upload headroom early, not a reason to choose one codec based on a presumed quality advantage. Use H.264 when it is the supported option in your software and stream setup, then test it at the relevant bitrate.
Using NVIDIA's approximate 75% upload allocation rule of thumb, a 50 Mbps video bitrate implies about 67 Mbps of measured upload capacity. This is a calculation from the guidance, not an official YouTube threshold; actual requirements vary with audio, overhead, and network use. If your measured capacity is below what the stream needs, reducing the bitrate without adjusting the output goal may make the ingest unstable or lower the stream's delivered quality. Consider a lower resolution or frame rate instead, then test again.
Do not use the H.264 value by habit if the encoder is set to AV1 or HEVC. Equally, do not enter 35 Mbps merely because it worked in another preset if the active encoder is H.264. Confirm the codec in the streaming software and in any available YouTube stream information, then keep the setting and the codec together in your notes.
Set output, rate control and keyframes
Set the output to 3840 × 2160 and 60 fps only if that is the stream you intend to deliver and the PC can produce it in a representative test. A source video or game running at 4K does not by itself confirm that the streaming software's output is 4K. Check the output or video tab in the application and inspect the resulting stream information in YouTube Studio.
Use CBR for the bitrate mode where it is available. Set the keyframe interval to two seconds; YouTube's guidance recommends that interval and says not to exceed four seconds. Choose RTMPS for the connection when offered. These are ingest-side settings, separate from whether the graphics card can maintain the encoding workload.
For stereo audio, YouTube lists AAC or MP3 at 44.1 kHz and 128 kbps. If you are sending 5.1 audio through RTMP or RTMPS, YouTube's guidance specifies AAC support. Keep the first test simple: stereo AAC is a sensible baseline unless the programme genuinely requires surround sound.
For standard dynamic range, set Rec. 709 and 8-bit colour as the baseline. If the stream is HDR, check the whole workflow—capture, encoder, software output, and YouTube ingest—rather than changing a single checkbox and assuming the format is correct. YouTube's listed HDR settings recommend H.265/HEVC at 10-bit and do not support AV1 for HDR in that guidance.
One more setting affects expectations: YouTube says the option to improve a 4K stream for low latency is unavailable. The 4K live mode is optimised for quality with normal latency, so do not build a plan around selecting that 4K low-latency option. Read YouTube's current encoder page before a high-stakes event, because platform settings can change.
Test stream health and system load
Run an unlisted or otherwise appropriate test before the public broadcast. Include the audio and motion your actual stream will contain: a quiet static screen can conceal problems that appear when a game camera turns, a video has rapid cuts, or audio processing is active. YouTube advises testing with representative content, monitoring stream health, and reviewing messages during the event.
Watch both the software's encoder status and YouTube's stream health. If frames are skipped or the output stalls, note when it happens and what else the PC is doing. A game or 3D scene can use GPU resources that the encoder and capture path also need. Test the stream with the game in its expected settings, overlays enabled, and any scheduled media or browser sources running.
Check the network separately. A stable local application does not prove that enough upload is available throughout the broadcast. Test while the household or venue is using the connection normally, use a wired connection where practical, and avoid starting large uploads or backups during the stream. A bitrate target must fit the real connection, including audio and overhead.
Change one variable at a time. If YouTube reports a connection issue, first check upload stability and competing network use. If the software reports encoding overload, reduce encoder or game workload, or step down resolution or frame rate. If the stream reaches YouTube but motion looks poor, verify codec and bitrate before changing unrelated capture settings. The guide to fixing a YouTube stream that stops after one loop concerns a different failure, but it is a useful reminder to test the complete stream behaviour rather than only the first few minutes.
If your channel is a continuous prerecorded loop rather than a live game, the bottleneck may be keeping the programme running rather than rendering a demanding scene locally. A guide to looping a video into YouTube Live with FFmpeg covers that distinct workflow; it does not remove the need to set an appropriate codec, bitrate, and ingest configuration.
Decide whether local encoding fits the channel
An RTX 4060 can be a suitable starting point for a local NVENC setup, but that is not the same as proving a particular computer is a sound unattended broadcaster. Local encoding asks the PC to stay on, the software to remain configured, and the network connection to remain usable. If the channel is a fixed prerecorded programme and the recurring pain is having a computer run overnight, StreamNeo removes that particular need to keep your own computer switched on by turning an uploaded video into a YouTube live stream.
For a locally produced stream, keep the test routine even if a short run succeeds. A gaming channel has variable render load; a devotional or ambience channel may have comparatively still visuals but still needs uninterrupted audio and a reliable source loop. If you are choosing a setup for different prerecorded segments, this overview of scheduling videos in OBS helps distinguish playlist scheduling from encoder configuration.
A sensible fallback is a lower output resolution or frame rate that your own test sustains, not a higher bitrate chosen in the hope that it will fix a dropped connection or overloaded encoder. Recheck the official YouTube guidance before changing a stream that has been stable, and record the settings and observations so you can reproduce the result.

FAQ
What bitrate should I use for YouTube 4K 60fps?
YouTube recommends 35 Mbps for AV1 or HEVC and 50 Mbps for H.264 at 4K60. Select the codec first, then use its corresponding bitrate as a starting point and test the full stream.
Should I use AV1 or H.264 with an RTX 4060?
Use AV1 for SDR if your software and YouTube stream setup expose it; the RTX 4060 supports AV1 encode, but the option is not guaranteed in every configuration. If AV1 is unavailable, choose another supported codec such as HEVC or H.264, following its own bitrate recommendation.
What NVENC settings should I use in OBS?
Start with NVENC, the available supported codec, CBR, a two-second keyframe interval, RTMPS, and the codec-specific YouTube bitrate. Check OBS output resolution and frame rate separately, then test with the scene and audio you will actually broadcast.
Can an RTX 4060 guarantee a stable 4K60 stream?
No. The card's codec capability does not establish what a particular PC, game, scene, driver, software configuration, or network can sustain. Test representative conditions and step down resolution or frame rate if the complete setup is unstable.
