THE NUMBERS, EXPLAINED
How to use this calculator.
Non-drop-frame integer-rate timecode only. 29.97/59.94 drop-frame conventions are not supported in this version.
Start with your inputs
Enter timecode hh:mm:ss:ff, integer frame rate. Keep amounts in the units shown on each field. The example is a starting point, not a recommended value.
| Input | Example value |
|---|---|
| Timecode HH:MM:SS:FF | 00:01:00:00 |
| Integer frame rate | 30 |
A worked example
With the example inputs above, frame count is 1,800. Change the inputs to explore your own scenario.
| Result | Example answer |
|---|---|
| Frame count | 1,800 |

Symbols and units
- a
- Timecode HH:MM:SS:FF
- b
- Integer frame rate
Use the units shown. A list keeps the order in which you enter its values. The symbol ^ means “raised to the power of”.
Calculation steps and notation
For HH:MM:SS:FF and integer frame rate r, total frames = ((HH × 60 + MM) × 60 + SS) × r + FF. This is non-drop-frame counting.
Assumptions and limits
Non-drop-frame integer-rate timecode only. 29.97/59.94 drop-frame conventions are not supported in this version.
Calculations use the values you enter. Blank or invalid inputs show an error instead of silently substituting zero. Results are displayed to useful precision; calculations retain the underlying numeric precision.
Questions about this tool
What does the result tell me?
Frame count. The result applies to the method and inputs described above. Check the units and assumptions before using it in a decision.
Why might another calculator differ?
Differences in units, rounding, timing or model definitions can produce different answers. Compare the input definitions and the method, rather than only the final number. For this tool: Non-drop-frame integer-rate timecode only. 29.97/59.94 drop-frame conventions are not supported in this version.
Are my inputs stored or sent to AI?
Calculations on this page happen in your browser. The separate AI question finder sends its submitted conversation to OpenAI; these calculator fields are not sent. Favourites and recent tool names are stored locally. A shared link contains the inputs you choose to include.
