Great thread!
One wrench, at least to me. How does drop frame fit into the mix. ie. Isn't 23.98 a non drop format, but 29.97 can either be DF or ND - of course video for broadcast is DF where DF just accounts for the .03 difference if I understand this correctly.
My question revolves around a 23.98 ND project converted to a 29.97 DF project. If I look at the counters of both projects across a 22 minute show, the difference adds up to a couple of seconds due to the 2 frames occasionally not counted (but the video not physically omitted.) I have done this on our video system by burning in the 23.98 TC and pulling it out to NTSC 29.97DF and superimposing the new TC. Some posters above have mentioned that the frame rate would match - mine is close, but not dead on - unless I misunderstood the post...
