This calculator simulates flicker problems caused by HMI, LED and other light sources. The program calculates the relative exposure of each single frame and the total amount of flicker on film.

Important: This software is just a guideline to evaluate flicker effects. I do not take any liability for any damage resulting from the use of this software, in particular if the effect on the exposed footage or recorded medium does not match the calculations. If you intend to use the results of a calculation for a shoot, it is necessary to verify them first by shooting a test! Use the Flicker Calculator only if you agree with this condition!
