If only it were dead dead. Not kind of dead, but actual dead. Instead, it's the walking dead. There is so much content recorded in NTSC that is still needing to be dealt with for the non-NTSC formats of today and tomorrow. So many people have done so many bad things to an NTSC video due to a lack of understanding the peculiarities of NTSC that causes us today so much pain.
NTSC was such a total kick the can down the road solution. The number of B&W sets that had been sold that forced the decision to make the signal remain compatible with those B&W sets is such a small number that we probably see that same number of sales in a week now. Hindsight and all that, but the repercussions of that decision has cost the industry so much. Then again, niche jobs exist because of it, and I've pretty much made a living from it.
Honest to goodness engineers required to operate equipment, interlacing, 3:2 pulldown, broken cadence, color burst, 1 volt peak-to-peak, IRE, waveforms/vectorscopes, pedestal, blacker than black, TBCs and video/black/chroma/hue, whiter than white, broadcast safe, chroma bleed, audio anomalies because the video signal was too strong, pincushioning to TV monitors because the video signal was too strong, and sooo many more issuess that I'm so happy to see go the way of the dodo.
