David did a GREAT impression !
The only time I ever use tri level sync is when the customer MUST work in 23.98 (or 24). But in my world, since everyone is using Panasonic HD VTR’s which have the 2:3 pulldown (turing the 23.98 into 59.94), or Sony JH-3 VTR’s (which do the same pulldown trick), I almost NEVER have to use a tri level sync gen, as everything is being done at standard frame rate (59.94), so a cheapie black generator works just fine for these projects. However, as David said, if you MUST output at 23.98 to (for example) a Sony HDW-M2000/10, you MUST MUST MUST use a tri level sync generator to lock everything. Since George Lucas is not one of my clients, I don’t ever see ANYONE dumping back at 24p. I guess if I lived in LA, it would be a different story.

ps – and you were right, long after the PCI-X G5, the Quad G5, the Kona 2, the Blackmagic Extreme, the AVID Adrenaline are gone, the $5000 Evertz 7750 Tri Level Sync Gen will be completely usable, just as everyone’s NTSC black genenerator they owned (back in the linear video days) is just as good as any sold today.
