Why the Right Bitrate Matters
Why the Right Bitrate Matters
The best bitrate for streaming is the highest one your connection can hold steady.
Too low
Your video looks blurry and blocky, especially during fast movement.
Too high
Your connection can’t keep up, so your stream buffers and drops frames.
Just right
A sharp, smooth stream from start to finish.

Best Bitrate for YouTube, Twitch, Facebook & More
Every platform limits how much bitrate it accepts. If you go over it, your stream can be rejected or look worse. Here are the YouTube bitrate, Twitch bitrate and other platform limits at a glance.
| Platform | Bitrate limit | Good to know |
|---|---|---|
| YouTube | Up to 17,000 kbps (1080p 60 fps) and 50,000 kbps (4K 60 fps) | Recommended. YouTube makes lower-quality copies for viewers on slow connections. |
| Facebook Live | 15,000 kbps | Recommended max, at up to 1080p 60 fps. |
| Kick | 8,000 kbps | Max, at up to 1080p 60 fps. No H.265 or VBR. |
| Twitch | 6,000 kbps | Recommended max, even at 1080p 60 fps. |
| LinkedIn Live | 6,000 kbps | Max for video, plus 128 kbps for audio. |
Streaming to several platforms with OneStream Live? Pick a bitrate that fits the lowest limit. Platforms update their limits from time to time, so check their guidelines before a big stream.
Match Your Bitrate to Your Upload Speed
A good starting point is about 75% of your upload speed. The rest leaves room for audio and small speed drops. For example, a 10 Mbps upload gives you about 7,500 kbps. Not sure what your connection can handle? Use our Bandwidth Calculator.
OBS Bitrate Settings
Go to Settings › Output and set Output Mode to Advanced. In the Streaming tab, set Rate Control to CBR, enter your Bitrate, and set Keyframe Interval to 2 seconds.
Stream Stuttering? Try This First
Then run the calculator again. A smooth 720p stream always looks better than a 1080p stream that keeps freezing.
Frame rate
Drop from 60 to 30 fps. This works well for talking, teaching and slower content.
Resolution
Drop from 1080p to 720p. This works better for fast games and sports.
Tips for a Smoother Stream
Tips for a Smoother Stream
Small changes that keep your stream smooth from start to finish.
Use a wired connection
An Ethernet cable is more stable than Wi-Fi.
Pause other internet use
Downloads, updates and video on other devices can slow your stream.
Try hardware encoding
If your computer struggles, choose NVENC (NVIDIA) or AMF (AMD) in OBS to take the load off your CPU.
Recheck after any change
New internet plan, router or location? Run the calculator again.

Frequently Asked Questions
Frequently Asked Questions
Have a question about bitrate? We’ve got answers.
What is bitrate, and how do I convert kbps to Mbps?
Bitrate is how much data your stream sends every second. Video bitrate controls how sharp your picture looks, and audio bitrate controls how clear your sound is. It’s measured in kbps or Mbps. To convert kbps to Mbps, divide by 1,000. For example, 6,000 kbps is 6 Mbps, and 7,500 kbps is 7.5 Mbps.
Is this bitrate calculator free?
Yes. The bitrate calculator is free to use, with no sign-up, email or download needed.
What bitrate should I stream at?
It depends on your resolution, frame rate, upload speed and platform. Enter your settings into the calculator above, keep the result within your platform’s limit, and run a test stream.
What is the best bitrate for 720p, 1080p and 4K?
YouTube recommends these minimum bitrates for H.264 streams: 720p, 3,000 kbps; 1080p at 30 fps, 5,000 kbps; 1080p at 60 fps, 6,000 kbps; 4K at 60 fps, 14,000 kbps. Twitch, Kick and LinkedIn have lower maximums, so check the table above.
CBR vs VBR: which is better for live streaming?
Use CBR (constant bitrate) for live streams. It sends a steady amount of data, which is what YouTube and Kick ask for. VBR (variable bitrate) can spike during busy scenes and cause buffering, so save it for recordings.
