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.
Recommended bitrate
-
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
- Enter the resolution.
- Set the frame rate.
- Choose the quality factor.
- 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.
