Bitrate
What is it?
Bitrate is how much data per second a video uses — usually written in kbps or Mbps. It's the single biggest dial controlling the quality-versus-size trade-off: more bits per second = sharper, smoother picture, but heavier to send and receive.
Think of it as water flow through a pipe: a wide flow (high bitrate) carries rich detail; a thin flow forces the picture to become softer and blockier.
Practical example
A streamer sets their app to 4,500 kbps for a 1080p broadcast and everything looks crisp. At a café with weak Wi-Fi that can only upload 1,500 kbps, the same settings cause constant freezing — dropping the bitrate (and resolution) to match the connection instantly fixes it. The connection didn't change; the demands on it did.
Key things to know (non-technical)
- The creator's upload speed is the hard ceiling: streaming at a bitrate above what the network can carry guarantees a broken stream.
- Common rough pairings: 1080p ≈ 4–6 Mbps · 720p ≈ 2.5–4 Mbps · 480p ≈ 1–2 Mbps.
- Fast-motion content (sports, gaming) needs more bitrate than a static talking head at the same resolution.
- Bitrate also drives costs: viewer bandwidth, CDN bills, storage size of recordings.
In Tupic Live
Tupic Live can protect creators from this complexity with an auto-bitrate feature: test the connection, pick safe settings, and quietly adapt during the show — turning the most common cause of failed streams into a non-issue.
