Hi Fred,
I'd recommend looking at scheduled playback in order to generate frames for keying, see SDK manual section "2.4.8 Keying" for a high-level overview.
Your application would have to generate video frames with the current value of the timer drawn into the buffer at the rate appropriate for the active video mode.
I recommend against calling DisplayVideoFrameSync every millisecond, as even in p60 modes the minimum frame interval is 16.6ms.
Cheers,
