Thanks to oktobor for supporting the TIG
Bob, I am so sorry about your brain.

Lets see if this soothes it.

The whole deal is really very simple, and I should have written the details 
so that no confusion occurred!

The camera is capable of high speed, full resolution up to 1000fps, or so 
the blurb tells me. As we have hidef in our Inferno/Flame set up, we would 
do any blue screen compositing in hidef, then drop down to SD at the last 
stage for transmission. I was asked if they should back up on 35mm. I don't 
have HD in my telecine. Thus, my first reaction was don't bother........

A private posting sent to me mentioned lighting.... And I have to agree, if 
the lighting isn't right....... But I know the DP, and that should be fine.

So, to sum up. This project will end up on air in SD only.

Feeling better Bob?
