Time after time I've put the oscilloscope on the 30 fps signal and found it to be 29.97. Maybe I'm too old to not measure such claims but today after 2 decades plus of electronics design I can't find 30 fps signals.
What exactly is outputting this?
And a good digitizer will not lose sync. Try it. Any other answer would be predicting the future.
I am recording an output composite video signal of 30 fps (EIA RS-170) on to a digital video casette recorder (Sony GV-D1000) that operates with 29.97 fps (specified as "NTSC Color, EIA Standard" (presumably RS-170A).
Does anybody know what happens during that process with regard to audio sync and frame dropping?
Audio sync is very critical in my project but it is difficult for me to test on my own. Are there typically inherent mechanisms in camcorders that process and record 30 fps to 29.97 keeping the audio in perfect sync?
Thanks in advance,
