FPS timecode calculator

Fill in either the timecode or the frame count and get the other, plus the position in seconds. Timecode is hours, minutes, seconds and frames, so its meaning depends entirely on the frame rate.

This calculates non-drop timecode, where every frame is counted and the timecode is simply a base-rate number. Drop-frame is a different thing and mixing them up is the classic way to be two seconds out over an hour. At 29.97 fps, real time runs slightly slower than the timecode counting at 30, so drop-frame skips two frame *numbers* at the start of most minutes to keep the timecode matching the wall clock. No frames are lost — only labels are skipped — which is why a drop-frame timecode cannot be converted to a frame count with the arithmetic here.
