  Timecode calculator and converter
The timecode calculator allows to perform basic calculation (addition / substraction / multiplication / division) on video timings as well as video conversions between different formats.

Perform calculations

Calculations are carried out as in a common calculator. However, negatives values are not allowed. You can enter the numbers from the calculator's keypad with the mouse.

You can use the memory functions for simple calculations. MR is used to retrieve the value in memory. M+ adds the current value to the value in memory. M- substract the current value of the memory. MC will clear the memory.

Perform format conversions

You can perform conversion on a calculated value or an input value between several formats To convert a value from one format to another, choose the desired format from  the drop down list.

The following formats are available:

- Timecodes: Timecodes are stored according to the "hh:mm:ss:ff" notation (hh: hours, mm: minutes, ss: seconds, ff: number of frames)

60 frames per second
69.94 frames per second (non-drop frame)
59.94 frames per second (drop frame)
50 frames per second
29.97 frames per second (non-drop frame)
29.97 frames per second (drop frame)
25 frames per second
24 frames per second
23.98 frames per second (non-drop frame)
23.98 frames per second (drop frame)

- Feet lengths (expressed in feet:frames): Feet lengths are stored according the "ft:frms" notation (ft - number of feet, frms - number of frames).
