OBS Bitrate Settings for Twitch and YouTube in 2026

Open Twitch's broadcasting guidelines and the recommended bitrate for a 1080p60 stream is 6,000 Kbps. Open YouTube's official live encoder settings page for the exact same resolution and frame rate, and the recommended ceiling is 17 Mbps, nearly three times higher. That gap is not a mistake on either company's part. It is the clearest evidence that Twitch and YouTube deliver your video to viewers in fundamentally different ways, which is why a single universal "best bitrate settings" number for streaming does not exist.

Key takeaways

Twitch's broadcasting guidelines recommend 6,000 Kbps for 1080p60 and 4,500 Kbps for 1080p30.
YouTube's official live encoder page recommends up to 17 Mbps (H.264) or 12 Mbps (HEVC/AV1) for that same 1080p60 stream.
Both platforms specifically recommend constant bitrate (CBR) encoding with a 2 second keyframe interval, not variable bitrate.
Streaming guides consistently recommend keeping your bitrate at or below about 80 percent of your tested, sustained upload speed, not your advertised plan speed.

Why the Same Resolution Gets Two Different Bitrate Budgets

The gap between Twitch and YouTube comes down to what happens to your video after you hit "start streaming." According to YouTube's own help documentation, "YouTube will automatically transcode your live stream to create many different output formats so that all of your viewers across many devices and networks can watch." In other words, nobody watching your YouTube stream actually receives your 17 Mbps source feed. YouTube's servers immediately compress it down into a full ladder of smaller renditions, from 4K down to 360p, and a higher quality source simply gives that transcoding process more detail to work with.

Twitch has historically worked the other way. As Twitch explained in its own January 2024 announcement of a new broadcasting feature, the platform "could only guarantee transcodes to Partners" because of server costs and capacity limits. For a large share of Affiliates and smaller streamers, viewers have received something very close to the broadcaster's original source stream, with no server-side downscaling cushion in between. That is why Twitch keeps its recommended ceiling low enough to still play back smoothly for a viewer on an average home or mobile connection, even though it means a visibly softer picture than a well tuned YouTube stream at the same resolution.

How Much Upload Speed Does 1080p60 Actually Require?

For a straight answer: streaming 1080p60 to Twitch at its recommended 6,000 Kbps video bitrate, plus roughly 160 Kbps of AAC audio, needs a little over 6 Mbps of available upload bandwidth, and guides recommend keeping that bitrate under about 80 percent of your tested sustained upload, so budget for around 7.5 to 8 Mbps of real, measured upload speed before you start.

That number changes completely if you are streaming to YouTube instead. Hitting YouTube's own recommended 17 Mbps for 1080p60 H.264 means you need upload speeds most home connections, especially on cable or older fiber plans with asymmetric speeds, simply do not have. This is the practical reason so many streamers end up running YouTube well under its recommended ceiling: the chart describes what YouTube's transcoder can use to best effect, not a minimum you are required to hit.

The Platform Numbers, Side by Side

Resolution / FPS	Twitch recommended	YouTube recommended (H.264)	YouTube recommended (HEVC/AV1)
1080p60	6,000 Kbps	17 Mbps	12 Mbps
1080p30	4,500 Kbps	14 Mbps	10 Mbps
720p60	4,500 Kbps	8 Mbps	6 Mbps
720p30	3,000 Kbps	8 Mbps	6 Mbps

Two things stand out in that table. First, YouTube does not actually lower its recommendation much between 60fps and 30fps at 720p, since its transcoder cares more about source detail than frame-by-frame motion at that resolution. Second, Twitch's numbers have stayed close to these figures for years, while YouTube periodically revises its chart as its transcoding infrastructure improves, so it is worth rechecking YouTube's page before a major stream rather than trusting an old screenshot.

The Settings That Matter More Than the Number on the Slider

Bitrate gets all the attention, but three other settings decisions determine whether that bitrate is actually usable:

Rate control: Set CBR, not VBR. Both Twitch and YouTube explicitly recommend constant bitrate for live streaming, because a variable rate can spike above what your upload connection or the platform's ingest server can handle during fast motion.
Keyframe interval: Set it to 2 seconds. This is the interval most platforms require for their video segments to align correctly, and leaving it on "auto" can push some encoders toward a much longer interval that breaks quality switching for viewers.
Codec: H.264 is still the safe default for compatibility. HEVC and AV1 need roughly 30 to 40 percent less bitrate for the same visual quality, which is why YouTube's own chart recommends a noticeably lower number for them, but AV1 encoding on Twitch currently depends on specific hardware, discussed below.

If you are shopping for a GPU partly because its hardware encoder will carry this load instead of your CPU, it is worth comparing current NVENC generations before you buy; our RTX 5060 vs RTX 5070 comparison covers the encoder differences between those two cards specifically.

Who This Guide Is For, and Who Can Skip It

This matters most if you stream regularly to Twitch or YouTube and have never actually measured your real upload speed, if you stream from a laptop or older CPU and are deciding between software (x264) and hardware (NVENC, AMD AMF, Quick Sync) encoding, or if you are moving from Twitch to YouTube (or running both at once) and are confused why your usual settings look worse on one platform. You can safely skip the detailed tuning if your stream already runs for hours without dropped frames and viewers are not complaining about blur during fast motion; in that case your current settings are working, and chasing a marginally higher number is not worth the risk of destabilizing a setup that already holds up.

The Honest Limit of Any Bitrate Chart

The strongest counterargument to all of this is simple: these are recommendations, not guarantees, and plenty of successful streamers run outside them. A streamer with a very stable, low latency fiber connection can sometimes push Twitch past 6,000 Kbps without visible problems, since the real constraint is Twitch's ingest server behavior and viewer playback conditions, not a hard technical ceiling written in stone. Likewise, a YouTube streamer on a slower connection can still look perfectly good at well under 17 Mbps, because the encoder's efficiency and your source content (a talking head versus a fast-paced game) matter as much as the raw number.

It is also worth being honest that both platforms' guidelines move. Twitch's Enhanced Broadcasting feature, introduced in beta in January 2024 and built with GPU makers, lets a streamer's own GeForce RTX graphics card generate multiple quality encodes locally instead of relying on Twitch's servers to transcode after the fact, which is Twitch's own long-term answer to the exact ceiling problem described above. Twitch has said AV1, one of the codecs the feature can output on RTX 40 series cards, is roughly 40 percent more efficient than H.264. None of that changes what you should set today if your hardware does not support it, but it means today's numbers are a snapshot, not a permanent law.

A Simple Decision Rule for Setting Your Bitrate

Run a sustained upload speed test (not a quick burst test) while another device is idle, and note the lowest consistent number over a few minutes.
Pick a target bitrate at or below roughly 80 percent of that measured number, never your plan's advertised speed.
Match that target against the platform's own chart for your resolution and frame rate: Twitch's or YouTube's, from the table above, not a generic "best settings" list.
If the platform's recommended number is higher than your 80 percent ceiling, drop resolution or frame rate before you drop below the platform's floor, since an unstable high-resolution stream looks worse to viewers than a stable lower one.
Set CBR and a 2 second keyframe interval regardless of which number you land on.

The takeaway is not that one platform's settings are "right." It is that Twitch and YouTube optimized their recommendations for different jobs, raw near-direct delivery on one side, heavy server-side transcoding on the other, and copying a number from the wrong platform's chart is a common, avoidable reason streams look worse than they should. Measure your actual upload speed, use the table above for whichever platform you are actually streaming to, and treat CBR plus a 2 second keyframe interval as non-negotiable regardless of the exact number you pick.
