I can’t say as I fault them as I’ve spoken with teachers that don’t know how to handle telecine content. I also know plenty of editors that have no idea the purpose of a waveform/vectorscope. Again, neither did some of those instructors.

For people never having to work with this kind of content, it makes sense. I’d equate it to modern programmers not knowing Assembly, but can write apps that perform adequately. There’s plenty of content shot on modern equipment delivered to non-broadcast platforms that will never need to know the hows/whys old timers did what they did
