tcCalc - timecode & frame calc3.8 - App Store

tcCalc is a calculator built for one job: timecode math for video production. Add and subtract timecode, let it handle drop frame for you, and switch to a frame count with a single tap, all with the feel of an ordinary calculator.

Time bases
23.98 / 24 / 25 / 29.97 / 30 / 50 / 59.94 / 60 fps, plus hh:mm:ss for working without frames. Drop frame is applied automatically at 29.97 and 59.94 fps.
