Streaming Bitrate Quality Calculator
Estimate the video bitrate a streaming quality needs from resolution, frame rate and a bits-per-pixel quality factor for your codec.
How it works
Bitrate = width · height · fps · bits-per-pixel · Data/hour (GB) = bitrate · 3600 ÷ 8 ÷ 10⁹
A frame carries width × height pixels, and a codec spends some number of bits on each one; multiplying by the frame rate gives the bits per second. The bits-per-pixel factor captures both the codec’s efficiency and the visual complexity of the content — modern codecs like HEVC and AV1 need far fewer bits per pixel than H.264 for the same look, while fast motion and fine detail push the factor up. It is a planning estimate, not a substitute for a real encode.
Worked example
1080p (1920×1080 = 2,073,600 pixels) at 30 fps with an H.264 factor of 0.10: 2,073,600 × 30 × 0.10 = 6.22 Mbps. Over an hour that is 6.22M × 3600 ÷ 8 ÷ 10⁹ ≈ 2.8 GB.
Frequently asked questions
What bits-per-pixel value should I pick?
For H.264, 0.08–0.12 covers most content; HEVC and AV1 achieve the same quality near 0.05–0.07 thanks to better compression. Raise the factor for high-motion sports, video games or grainy footage, and lower it for talking-head or screen-share content that compresses easily.
Why do streaming platforms recommend specific bitrates?
Their guidelines bake in a typical bits-per-pixel value for their codec and audience bandwidth. This calculator lets you reverse-engineer that: plug in the resolution and frame rate, choose a quality factor, and you get a bitrate in the same ballpark as the platform’s chart.
Does higher bitrate always look better?
Only up to a point. Beyond the bitrate a codec needs to encode the content cleanly, extra bits are wasted — the picture is already transparent. Below it, you see blocking and smearing. The right factor targets that sweet spot for your codec and content.
