i think i was misdirected by SDK sample SignalGenerator.cpp:
[...]
videoDisplayMode->GetFrameRate(&frameDuration, &frameTimescale);
// Calculate the number of frames per second, rounded up to the nearest
integer. For example, for NTSC (29.97 FPS), framesPerSecond == 30.
framesPerSecond = (frameTimescale + (frameDuration-1)) /
frameDuration;
[...]
