Why Is My Stream Blurry? The Bitrate Math That Fixes It
Your game looks crisp on your monitor. Your stream looks like it was filmed through a shower door. Nine times out of ten, that's not your camera or your PC — it's bitrate: how much picture data you send per second.
Think of bitrate as the size of the pipe. A calm talking scene sips data. A fast game — racing, shooters, anything with grass — GULPS it. Same pipe, not enough water: the picture smears. That's the blur.
The only three numbers that matter
- Your upload speed. Test it (speedtest.net). Not the number on your internet bill — the number you actually get, right now.
- Your bitrate. What you tell the app to send.
- Your resolution + frame rate. Bigger picture, more frames = more data needed to stay sharp.
The rules that keep you safe
- Kick's rule: upload at least TWICE your bitrate. 6,000 kbps stream → 12 Mbps upload or don't.
- The 70% rule (OBS crowd's version of the same idea): never set bitrate above ~70% of your tested upload. Your internet also has to live its own life.
- Whichever rule you use: leave headroom. A stream at the ragged edge doesn't look better — it drops frames and looks worse.
What each platform allows
| Platform | Max bitrate | Hard rules |
|---|---|---|
| Kick | 8,000 kbps | H.264 only, CBR only, 2s keyframe, up to 1080p60 |
| Twitch | 6,000 kbps (non-affiliate guideline) | CBR, 2s keyframe |
| Multistream to both | 6,000 kbps | The strictest platform sets the number |
Pick your pairing (don't just max the slider)
| Picture | Bitrate | Upload you need |
|---|---|---|
| 1080p, 60 fps | 6,000–8,000 kbps | 12–16 Mbps |
| 720p, 60 fps | 4,000–5,000 kbps | 10 Mbps |
| 720p, 30 fps | 3,000–4,500 kbps | 9 Mbps |
Here's the secret nobody tells new streamers: 1080p at a starved bitrate looks WORSE than 720p at a healthy one. If your upload is modest, own 720p and make it clean. Viewers pick smooth and sharp over big and blurry, every time.
Where to set it
Meld ⭐: Settings → General sets your Main Canvas. Your Stream Settings → Resolution is separate — you can stream at 720p while your canvas (and recording) stays 1080p. Turn the hardware encoder ON (NVENC on NVIDIA cards) in your output settings so your graphics card does the heavy lifting, not your CPU.
OBS: Settings → Output (switch to Advanced) for encoder, rate control (CBR), bitrate and the 2-second keyframe interval. Settings → Video for base and output resolution — streaming at 720p = Output (Scaled) Resolution 1280×720.
Use a hardware encoder if you have one: NVENC (NVIDIA), QuickSync (Intel), AMF (AMD). Software encoding (x264) makes your CPU encode video AND run your game. That's how "encoding overloaded" is born.
Still blurry? Work the list
- Are you actually sending the bitrate you set? (Dropped frames mean the pipe is failing — see the troubleshooting guide.)
- Is your upload shared right now? Someone streaming video in the next room eats your pipe.
- Wi-Fi? Plug in an ethernet cable and test again. Wi-Fi lies; cables don't.
- Fast-motion game at 1080p60 on 4,500 kbps? That's the blur, mathematically guaranteed. Raise bitrate or drop to 720p60.

Quick answers
Why is my stream blurry even though my internet is good? Usually the pairing, not the pipe: 1080p at a starved bitrate looks worse than 720p at a healthy one. Either raise the bitrate (if your upload allows) or drop to 720p and feed it properly.
Why does my stream get pixelated when I move in-game? Fast motion gulps data. A calm scene sips; a shooter or racing game at the same bitrate runs dry, and the picture smears into blocks. More bitrate, or less picture — those are the only two levers.
What bitrate should I use for 1080p60? 6,000–8,000 kbps, with 12–16 Mbps of real upload behind it. Kick caps at 8,000; Twitch's guideline tops out at 6,000.
Is 720p better than 1080p for streaming? On a modest upload, yes — smooth and sharp beats big and blurry, and viewers pick the clean picture every time.
