Concrete user question
How does the formula result change when resolution, frame rate or a user-entered bits-per-pixel assumption changes?
Tool
Bitrate Planning Calculator
Compare how dimensions and frame rate affect a formula when you supply the bits-per-pixel input yourself.
It is useful for sensitivity comparisons when the bits-per-pixel input is treated as an explicit user assumption to test.

How the calculation works
Reviewed: 2026-07-20Worked example
Example only: entering 1920 × 1080, 30 fps and 0.10 bits per pixel produces about 6.2 Mbps. The 0.10 value is a user assumption, not a recommendation.
Method
Enter width, height, frame rate and your own bits-per-pixel comparison value. The calculator performs only the displayed multiplication.
Open formula
formula Mbps = width × height × fps × user-entered bits per pixel ÷ 1,000,000.
Limitations
Bits per pixel is not a universal quality model. The calculator contains no official codec coefficients and makes no codec recommendation. Content complexity, encoder implementation and destination guidance can change the required bitrate substantially.
Next verification step
Compare the estimate with the destination's current official guidance, then encode and inspect a high-motion test range.

When to use it
- Compare 30 fps and 60 fps at the same dimensions.
- See how a user-entered bits-per-pixel assumption changes the result.
- Create a test hypothesis before checking an official delivery specification.
Use it inside FreeCut
Use the result as a planning value and compare it with the options actually visible in FreeCut 1.3 and the destination's requirements.
FAQ
FAQ
Is the result an official platform bitrate?+
No. It is the result of your own bits-per-pixel input in the visible formula. The destination's current official documentation takes precedence.
Does the calculator recommend a codec?+
No. It contains no codec coefficients or availability claims. Only the options visible in the installed FreeCut 1.3 export panel are available there.
Cut, calculate, export — in one app.
Use the documented FreeCut 1.3 export controls and verify the result against your actual destination. No forced FreeCut watermark.
