TC Duration is an online tool that calculates the duration between two timecodes. The timecodes it processes must have the same fps. To use TC Duration, you first choose the frame rate and then the IN and the OUT timecodes. The result will automatically be calculated as soon as you enter the second timecode.
If your input results in a calculation error, TC Duration will inform you. Hit the button COPY to save your result to the clipboard. If you want to reset the state of TC Duration, use the RESET button. Each result timecode has three parts: the timecode, the FPS of the timecode, and the frame count of the timecode.
