In the fast-paced world of video editing and content production, precision is everything. Whether you’re working on a short film, YouTube video, or commercial project, every frame counts. Calculating the difference or sum between two timecodes manually can be tedious and error-prone—especially when factoring in frame rates. That’s where our Timecode Calculator tool comes in.
Designed with simplicity and efficiency in mind, this tool allows you to add or subtract two timecodes based on your desired frame rate. It’s perfect for editors, filmmakers, and animators who want accurate results without having to fiddle with complex software.
Timecode Calculator
What is a Timecode?
A timecode is a sequence used to uniquely identify frames in video or audio production. It is formatted as HH:MM:SS:FF, where:
- HH = Hours
- MM = Minutes
- SS = Seconds
- FF = Frames (depending on your project’s frame rate)
For example, at 30 frames per second (fps), one second equals 30 frames. Therefore, calculating differences or adding durations needs to be precise to the frame.
About the Timecode Calculator Tool
This calculator helps you add or subtract two timecodes based on a specified frame rate. It features a clean and responsive design that works well across desktop and mobile devices. Some of its key features include:
- Easy-to-use inputs for hours, minutes, seconds, and frames.
- Frame rate (fps) selection from 1 to 120.
- Options to either add or subtract timecodes.
- Real-time result showing total frames and final timecode.
- Smooth user interface with modern styling.
- Reset button for quick reuse.
How to Use the Timecode Calculator
Follow these simple steps to calculate timecode values:
Step 1: Enter the First Timecode
Fill in the fields for hours, minutes, seconds, and frames in the “First Timecode” section.
Step 2: Enter the Second Timecode
Do the same in the “Second Timecode” section. This can be the duration you want to add or subtract.
Step 3: Set Your Frame Rate
Enter the frame rate (fps) that your project is using. Most standard videos use 24, 25, or 30 fps.
Step 4: Choose Operation
Select whether you want to Add or Subtract the timecodes.
Step 5: Click Calculate
Hit the “Calculate” button to get the result. You’ll see:
- The resulting timecode in HH:MM:SS:FF format.
- The total frame count of the resulting timecode.
If the result turns negative (in subtraction), the tool will alert you.
Step 6: Reset (Optional)
To reset all fields, click the reset icon button.
Example Usage
Imagine you’re editing a scene where one clip starts at 00:02:15:10 and another begins at 00:01:20:05. You want to know the total time if you played them back-to-back at 30 fps.
- First Timecode: 00:02:15:10
- Second Timecode: 00:01:20:05
- Frame Rate: 30 fps
- Operation: Add
After calculation, you’ll see:
- Resulting Timecode: 00:03:35:15
- Total Frames: 6450
This gives you a precise duration for combining those clips seamlessly.

Frequently Asked Questions (FAQs)
1. What does FF stand for in a timecode?
FF stands for Frames, representing the number of frames after the last second, based on your FPS.
2. What happens if I enter a frame rate less than 1?
You’ll get an alert—FPS must be at least 1.
3. Can I use decimal values in the FPS field?
No, only whole numbers are supported to maintain frame integrity.
4. What’s the maximum FPS allowed?
You can input up to 120 fps, covering most modern recording formats.
5. Will this tool work on my phone?
Yes, it’s fully responsive and optimized for mobile devices.
6. Is there a limit to how large a timecode I can enter?
You can enter up to 99 hours, which is more than enough for most projects.
7. Does it save my data?
No, it’s a stateless tool—nothing is stored.
8. What happens if I get a negative result?
You’ll see an alert, and the result will not be displayed.
9. Can I calculate durations longer than an hour?
Absolutely, the tool handles hours just like minutes and seconds.
10. Can I use this tool offline?
If you save the page locally, it will work without an internet connection.
11. What is Total Frames in the result?
It’s the entire duration expressed purely in frames, useful for syncing.
12. How is subtraction handled?
It subtracts the second timecode from the first. Negative results are not allowed.
13. Can I reset all fields at once?
Yes, click the circular reset button.
14. Is this tool safe to use?
Yes, there’s no data collection or tracking.
15. Can I embed this on my own site?
