Bitrate

The amount of data processed per unit of time in a video or audio stream.

What is Bitrate?

Bitrate refers to the amount of data transmitted per second during audio or video playback. It’s measured in kilobits per second (Kbps) for audio and megabits per second (Mbps) for video. A higher bitrate typically results in better quality — but also requires more bandwidth.

Bitrate in Streaming

In streaming, bitrate determines how much data is used to deliver a smooth experience. Platforms like Netflix, YouTube, and Twitch automatically adjust bitrate based on your connection to avoid buffering. Livestreamers often set bitrates manually to balance quality and performance.

Bitrate vs Resolution

Bitrate and resolution both affect streaming quality, but they are not the same:

Term What It Measures Affects
Bitrate Amount of data per second (Mbps/Kbps) Quality & bandwidth usage
Resolution Number of pixels (e.g., 1080p, 4K) Sharpness and detail

You can have high resolution with low bitrate — but it may look pixelated or blurry.

Ideal Bitrates for Streaming

Type of Content Recommended Bitrate
720p Video (30 fps) 2.5 – 4 Mbps
1080p Video (60 fps) 6 – 9 Mbps
4K Video (30 fps) 15 – 25 Mbps
Audio Streaming (MP3) 128 – 320 Kbps
Livestreaming (Twitch/YouTube) 3 – 6 Mbps (1080p)

Always check platform-specific guidelines — they may optimize differently for mobile vs desktop viewers.

FAQs

The video or audio will look and sound compressed — with blocky visuals, audio dropouts, or lack of detail.

Yes. Too high a bitrate can cause buffering if your internet speed can't handle it, and it uses more bandwidth unnecessarily.

Both matter, but bitrate often makes the difference between sharp, smooth playback and choppy, pixelated results — even at high resolutions.

Base it on your upload speed. Leave headroom (25–30%) to prevent dropped frames and aim for the platform’s recommended settings.

Yes. Most major platforms use adaptive bitrate streaming, which adjusts quality in real time based on your connection speed.
