I used to have a calculator called the FrameMaster. It was wonderful and useful for video editing and animation. Now this function is pretty much built in to the editing apps. However, you may find yourself in the field needing to do some simple timecode calculations, and then, THIS IS APP YOUR BEST FRIEND!
