ShowSMPTE() only works for 23.976, 24, 25, 29.97 and 30 fps because this is all we have specifications for.

Actually 23.976 is a hacked implementation of drop frame 24 fps because nobody has found the correct reference yet, but somebody wanted it and made a workable suggestion.

If you want to point to some reference for implementing alternate framerates or propose a useful enhancement please do.

If you want to just add framenumbers you can use ShowFrameNumber() or if you want timecodes based on a supported framerate but don't actually want to change the framerate do this...

Code:

Xyzzy=Last # Remember clip
AssumeFPS(30000, 1001) # Drop Frame NTSC exactly
ShowSMTPE() # Brand frames
AssumeFPS(Xyzzy) # Copy back original FPS
