    Help & Information

    Timecode Formats

    The calculator supports two common timecode formats:

    • HH:MM:SS:FF - Hours:Minutes:Seconds:Frames (e.g., 01:23:45:12)
    • HH:MM:SS.MS - Hours:Minutes:Seconds.Milliseconds (e.g., 01:23:45.500)

    Calculator Functions

    • Add - Adds two timecodes together
    • Subtract - Subtracts the second timecode from the first
    • Duration - Calculates the time difference between two timecodes
    • Convert - Translates between timecode formats, frames, and seconds
    • Offset - Applies a positive or negative offset to a timecode
    • FPS Conversion - Converts timecodes between different frame rates

    Tips

    • Use the framerate buttons to set the current working framerate
    • When entering timecode, you can use period (.) or comma (,) for milliseconds
    • For frames to timecode conversion, simply enter the frame number
    • For seconds to timecode, enter the number of seconds (can include decimals)
    • History is saved in your browser between sessions

    The Timecode Calculator is a professional-grade tool built for video editors, producers, and post-production teams who need precise and reliable timecode math as part of their everyday workflow. Whether you are adding or subtracting timecodes, calculating the duration between two points, converting between frames and seconds, applying offsets, or switching a timecode from one frame rate to another, this calculator handles all of it cleanly and accurately. It supports frame rates from 24 to 60 fps as well as custom rates, works with both common timecode formats, and saves up to 50 calculations locally so your history is always on hand between sessions.

    Timecode Formats Supported

    The calculator works with two standard timecode formats used across film, TV, and multimedia production:

    • HH:MM:SS:FF — Hours, Minutes, Seconds, and Frames (e.g., 01:23:45:12), used in frame-based editing workflows.
    • HH:MM:SS.MS — Hours, Minutes, Seconds, and Milliseconds (e.g., 01:23:45.500), used when millisecond precision is needed.

    How to Use the Timecode Calculator Online

    The calculator is organized into several functional sections. Here’s how to use each one:

    Step-by-Step Instructions:

    • Set Framerate: Click one of the preset buttons — 24, 25, 29.97, 30, 50, or 60 fps — or enter a custom frame rate (e.g., 23.976) and click “Set” to confirm. The current working frame rate is always displayed so you always know what you are working with.
    • Select Format: Choose between HH:MM:SS:FF (frame-based) or HH:MM:SS.MS (millisecond-based) depending on your project’s requirements.
    • Basic Calculations: Enter two timecodes (e.g., 01:23:45:12 and 02:34:56:23), select an operation — Add, Subtract, or Duration — and click “Calculate” to see the result instantly.
    • Conversion Tools: Input a timecode, frame count, or number of seconds, then select the conversion type — Timecode to Frames, Frames to Timecode, Timecode to Seconds, or Seconds to Timecode — and click “Convert” to get your result.
    • Timecode Offset: Enter a source timecode and an offset value, choose whether to add or subtract the offset, and click “Apply Offset” to generate the adjusted timecode.
    • Framerate Conversion: Enter a source timecode, select the source fps and target fps, and click “Convert FPS” to translate the timecode accurately between frame rates.
    • View History: Browse your past calculations, copy any result directly from the history log, or clear it entirely when you want a clean slate.

    Why Use the Timecode Calculator Online?

    Timecode errors in post-production can cause real problems down the line. Having a dedicated, accurate calculator at your fingertips keeps those errors from happening in the first place. Here’s what makes this tool stand out:

    • Versatile Calculations: Handles adding, subtracting, and duration calculations between any two timecodes with full frame-rate awareness, giving you precise results every time.
    • Flexible Conversions: Translates freely between timecode formats, raw frame counts, and seconds, covering the conversions that come up most often in editing and post-production work.
    • Framerate Support: Handles all standard frame rates including 24, 25, 29.97, 30, 50, and 60 fps, plus custom rates for less common project specifications.
    • Advanced Features: The offset tool and framerate conversion tool cover the more complex scenarios that basic timecode calculators often leave out, making this a genuinely complete solution for professional use.
    • Persistent History: Saves up to 50 calculations locally in your browser between sessions, so your recent work is always available for reference without needing to redo anything.
    • Ideal for Professionals: Whether you are editing a feature film, cutting a TV episode, or working on any multimedia production that relies on frame-accurate timecode, this tool gives you the precision and flexibility your workflow demands.
