Video Bitrate Calculator

Estimate a recommended video bitrate from resolution, frame rate and a quality factor, with the resulting file size per minute and hour. Calculated in your browser.

Show the math

Bitrate scales with the number of pixels pushed each second and a bits-per-pixel quality factor:

Mbps = width × height × fps × bpp ÷ 1,000,000

0.07 suits low-motion talking-head video, 0.1 is a good general default, and 0.15 holds up for fast action. Real encoders vary with codec and content.

What this does

A video bitrate calculator estimates a recommended bitrate from resolution, frame rate, and a quality factor, with the resulting file size per minute and hour.

How to use it

  1. Enter the resolution.
  2. Set the frame rate.
  3. Choose the quality factor.
  4. Read the bitrate and file size.

How it works

Bitrate scales with pixels per second and a bits-per-pixel factor: ~0.07 for talking heads, 0.1 as a default, 0.15 for fast action. Real encoders vary with codec and content.

Mbps = width × height × fps × bpp ÷ 1,000,000

Understanding your result

The recommended bitrate is a starting point that scales with resolution, frame rate, and how much motion your content has, more for fast action, less for a talking head. Real encoders vary by codec, so a modern codec like H.265 or AV1 looks as good at a lower bitrate than older H.264. Use the per-minute size to confirm the result fits your storage or upload limits.

Example

1080p at 30 fps and 0.1 bpp is about 6 Mbps.

Frequently asked questions

How is bitrate estimated?

It scales with pixels per second and a bits-per-pixel quality factor: Mbps = width × height × fps × bpp ÷ 1,000,000.

Which quality factor should I pick?

0.07 suits low-motion talking-head video, 0.1 is a good general default, and 0.15 holds up for fast action. Real encoders vary with codec and content.
