Calculating Timecode

The calculator that you use with fields that accept timecode and frame number values works like a standard calculator, but provides additional tools for calculating timecode and frame number values.

(a) Result field(b) Calculation Mode box(c) Drop Frame box

The calculator opens with the timecode mode (24 fps, 25 fps, 30 fps, 50 fps, and 60 fps) that applies to the default project resolution or the clip to which you are applying the value.

To calculate timecode:

1. Click a numeric field accepting timecode and frame numbers to open the calculator.
2. Use the integer and operation buttons to determine the value that you want to apply to the numeric field.
   TipTo enter two zeros for a timecode unit block, press . (period).
3. To switch between frame numbers and timecode, select an option from the Calculation Mode box.

   Select: | To calculate:
   --- | ---
   FRM | Values using frame numbers.
   TC | Values using timecode.

   TipYou can calculate a value in frames and apply the value to timecode. The value is converted automatically.
4. To switch between drop frame and non-drop frame timecode modes, select an option from the Drop Frame box.

   Select: | To calculate:
   --- | ---
   DF | Values using drop frame timecode.
   NDF | Values using non-drop frame timecode.

   TipThis box only appears when drop frame and non-drop frame modes are valid options.
5. To add the value in the calculator to the current value in the field, click Add.
6. To subtract the value in the calculator from the current value in the field, click Sub.
7. To close the calculator without applying further changes to the value in the field, click anywhere outside the calculator.
8. To enter the current value in the calculator—replacing the previous value—click the Result field in the calculator or press Enter.

   The calculator closes.

   TipYou can use the keys on the numeric keypad section of your keyboard to operate the calculator. Colons, semicolons, and other timecode notation marks are added automatically.
