For a 4K, 60 fps YouTube Live stream, set OBS to 3840×2160 at 60 fps, use CBR with a 2-second keyframe interval, and select a codec supported by both your AMD GPU and OBS. YouTube recommends 35 Mbps for AV1 or HEVC, or 50 Mbps for H.264. “Playlist” can mean a YouTube playlist URL, local video files, or a program assembled in OBS; those are different workflows, and the settings below cover YouTube ingest—not a guaranteed way to play or transition between playlist items.
What “playlist” means for this setup
A YouTube playlist URL, a sequence of local video files, and a continuous program assembled in OBS are not interchangeable. YouTube’s encoder guidance specifies how to send a live feed, but it does not establish that OBS can ingest a YouTube playlist URL as the live program or explain a particular source’s automatic advance or transition behavior. Confirm how your chosen source handles sequencing and transitions before relying on it for a broadcast.
YouTube also uses the term “playlist” for HLS delivery: HLS media is segmented and accompanied by a playlist for the player. That technical delivery format is not a viewer’s YouTube playlist and does not provide a recipe for playing a video playlist through OBS.
Choose a codec and bitrate
YouTube’s current live encoder guidance supports RTMP/RTMPS ingest and lists H.264, H.265/HEVC, and AV1. For 2160p (4K) at 60 fps, YouTube recommends the following video bitrates. These are YouTube’s guidance, accessed in 2026; the page does not state a publication year.

| Codec | YouTube’s recommended 4K60 video bitrate | Minimum listed by YouTube | Check before choosing |
|---|---|---|---|
| AV1 | 35 Mbps | 10 Mbps | Use only if your exact AMD GPU, driver, operating system, and OBS installation expose hardware AV1 encoding. YouTube’s cited live guidance does not support AV1 for HDR. |
| H.265/HEVC | 35 Mbps | 10 Mbps | Confirm that OBS offers hardware HEVC encoding for your GPU. YouTube requires HEVC for its live HDR path. |
| H.264 | 50 Mbps | 14 Mbps | A practical compatibility choice when it is the suitable hardware encoder available in OBS. |
The recommended figures are the quality-focused baseline; the listed minimums are not equivalent to the recommendations. These figures do not establish that one codec will look better than another for your particular video at these settings.
YouTube recommends RTMPS, constant bitrate (CBR), and a 2-second keyframe interval; do not exceed 4 seconds between keyframes. It supports frame rates up to 60 fps. For stereo audio, YouTube lists AAC or MP3 at 128 Kbps and recommends 44.1 kHz stereo. YouTube transcodes an incoming live stream into multiple viewer formats.

Check AMD and OBS support before configuring the stream
OBS documents AMD Advanced Media Framework (AMF) encoder support on Windows and Linux. The available hardware codecs depend on the exact GPU, drivers, operating system, and OBS installation, so do not assume every AMD card offers every codec. Verify the encoder choices in OBS itself. AMD’s streaming information describes its OBS integration with AMF, and AMD lists AV1 encoding on RDNA 3 and RDNA 4 devices. OBS’s format guidance identifies recent AMD cards, including RX 7000 Series, for hardware AV1.
- If OBS exposes AV1 for your AMD GPU, YouTube accepts it for live ingest and recommends 35 Mbps for 4K60 SDR.
- If OBS exposes HEVC, YouTube accepts it and recommends 35 Mbps for 4K60.
- If neither is available or suitable, H.264 is listed by YouTube and has a 50 Mbps 4K60 recommendation.
Hardware encoding can shift encoding work away from the CPU, but that alone does not guarantee that a specific PC can play the source, compose scenes, capture, and encode 4K60 without dropped frames or other performance problems. No exact GPU model or benchmark is established for this workflow. Check your current card, driver, and OBS encoder list before considering an upgrade; AMD Radeon RX 7000 Series is a category to investigate if hardware AV1 is needed, not a recommendation of a particular model.

Configure OBS and YouTube Live
- Prepare the YouTube broadcast. In YouTube Live Control Room, create or open the live stream and retrieve its current stream key. Treat the key like a password: do not share or publish it. In OBS, select YouTube as the service and connect using the current stream setup and key. YouTube’s encoder guidance recommends RTMPS.
- Choose the AMD encoder. Open OBS output settings and select the AMD hardware encoder and a codec that actually appears in the installed setup. Menu names can vary between OBS releases. If the desired codec is missing, check GPU and operating-system support, drivers, and OBS installation before settling on an available option.
- Set the video format. Configure the stream for 3840×2160 output at 60 fps. Make sure the source and scene composition can provide the intended frame rate; an output setting cannot create detail or motion that is absent from the source.
- Set rate control and bitrate. Choose CBR and use YouTube’s codec-specific recommendation: 35 Mbps for AV1 or HEVC, or 50 Mbps for H.264 at 4K60. Do not use the minimum as if it were the recommended quality-focused target.
- Set keyframes and audio. Set the keyframe interval to 2 seconds, not more than 4 seconds. For stereo audio, use AAC or MP3 at 128 Kbps and 44.1 kHz stereo, consistent with YouTube’s guidance.
- Test the actual program. Run a private or otherwise appropriate test with representative motion and audio. YouTube says, “Make sure to test before you start your live stream.” Review YouTube’s stream health and messages during the test and broadcast. Use a stable internet connection with capacity above the selected video bitrate, then validate it in practice; there is no universal upload-speed multiplier established here.
Set expectations for latency and HDR
Standard SDR
For ordinary SDR footage, use the settings above and keep HDR options disabled unless the source and complete encoding path are genuinely HDR. YouTube says the low-latency option is unavailable for 4K live streams; 4K streams are optimized for quality with normal latency. Do not promise a low-latency 4K viewing experience.
HDR
YouTube’s live HDR guidance requires compatible HDR source content and an encoder, and specifies HEVC for live HDR. Its OBS instructions call for an HDR source, YouTube HLS, a hardware HEVC encoder, Main 10 profile, P010 color format, and a supported HDR color space. YouTube’s general HDR configuration specifies 10-bit HDR, BT.2020 primaries, and PQ or HLG transfer characteristics. Confirm the exact AMD GPU supports the needed encoding path. Do not choose AV1 for YouTube Live HDR based on the cited guidance: YouTube’s regular live encoder guide says AV1 is not supported for HDR.

Troubleshoot common setup problems
- The AMD encoder or desired codec is missing in OBS: Hardware and codec availability vary by GPU, driver, OS, and OBS installation. Check those against the OBS and AMD compatibility guidance, update or correct the installed components as appropriate, and choose only an encoder that appears in OBS.
- YouTube reports stream-health problems or the picture stutters: Check whether the connection is stable and can sustain more than the selected video bitrate. Re-test with the same resolution, frame rate, motion, and audio; use OBS and YouTube health indicators to identify whether the issue is encoding or delivery rather than assuming a fixed bandwidth margin.
- The stream does not meet the intended 4K60 format: Verify OBS output resolution is 3840×2160 and frame rate is 60 fps, then confirm the source and composed scene can sustain them. A configured output does not prove the source contains native 4K detail or smooth 60 fps motion.
- Keyframe or bitrate warnings appear: Confirm CBR, a 2-second keyframe interval (never over 4 seconds), and the recommended bitrate for the selected codec. Recheck that the codec in OBS matches the bitrate you chose.
- A playlist item fails to advance or transitions are wrong: The ingest settings do not define playlist playback behavior. Check the documentation for the specific source or sequencing method and test the entire sequence, including transitions, before the real broadcast.
- HDR looks incorrect or cannot be enabled: Verify the source is HDR and that the full chain supports YouTube’s HEVC HDR path and required color settings. Do not apply HDR settings to SDR footage or treat AV1 as a supported YouTube Live HDR alternative.
