I posted these two questions several months ago, and got no replies, so I'll try again... There exist boards to take a video signal and put it into raster display memory. Is there a board or black box that allows a microcomputer to read the SMPTE timing signal from a videotape, providing that the signal is present? At this time, I don't know which video format would be involved, so the timing signal might be either on the separate control track or in the video interval. Another question. I am aware of the 3-2-3-2 method of converting a film shot at 24 fps into 60 field per second videotape. Is there a simple way for a computer using a "frame grabber" to be able to synchronize with this, i.e. to be able to tell which original frames occupy three fields and which occupy two? Yes, threes and twos alternate, but if the computer and the tape don't both put 'left foot first' the original frames will not be extracted properly. Please respond by email. If the answers seem to be of general interest, I will summarize... -- Mike Oltz oltz@tcgould.tn.cornell.UUCP (607)255-8312 Cornell Computer Services 215 Computing and Communications Center Ithaca NY 14853
