Why is my live stream blurry or low quality?
A blurry or pixelated live stream is almost always about how your video is encoded and delivered, not your camera. Here are the usual culprits, in the order worth checking, and how to fix each.
1. Your bitrate is too low for the resolution
Bitrate is how much data per second your stream uses — the single biggest lever on sharpness. Streaming 1080p at a bitrate meant for 720p makes fast motion (gameplay, sport) smear and block up.
As a rough guide: 720p30 wants ~3,000–4,500 kbps, 1080p30 ~4,500–6,000 kbps, and 1080p60 ~6,000–9,000 kbps. Raise the bitrate or drop the resolution until the two match.
2. Your upload can’t sustain that bitrate
If your connection can’t keep up, the platform throttles you and quality drops — or the stream stutters. Run an upload speed test and keep your bitrate comfortably below your sustained upload (leave ~30% headroom).
If you’re running separate outputs to several platforms from your own PC, each one adds to your upload — a common hidden cause of soft, dropping streams. Relaying server-side instead keeps your upload to a single stream.
3. Encoder settings and re-encoding
Use hardware encoding (NVENC, AMF, QuickVideo) if you have it, set the keyframe interval to 2 seconds, and match your output resolution to your scene. Every time a stream is re-encoded along the way it can lose quality, so avoid tools that transcode your feed unnecessarily.
4. The platform’s own transcoding
Platforms re-encode your stream into multiple qualities for viewers. You can’t change that, but giving them a clean, well-encoded source at the right bitrate is the best way to come out sharp on the other side.
Frequently asked questions
What bitrate should I use for 1080p?
Around 4,500–6,000 kbps for 1080p30 and 6,000–9,000 kbps for 1080p60, as long as your upload can sustain it with headroom.
Does restreaming reduce my quality?
It shouldn’t. A copy-first relay like Stream Repeater passes your encode through without re-encoding, so there’s no quality loss in the relay.
Why is my stream sharp at first then goes blurry?
That’s usually your upload dropping under load or the platform throttling a too-high bitrate. Lower the bitrate to what your connection sustains reliably.
