Cinema Tools "Conform" command

[Aureliano]

I've got an old 16mm student film I'm trying to resurrect. I've gotten a "test drive" from Bono Labs of Arlington, VA which included a 24fps telecine transfer of 35mm footage with a 3:2 pulldown, along with a transfer of the same footage with the telecine run at 30 fps. It's sci-fi, and I want to add visual effects, so having interlacing present in post would be a big pain in the keyster.

Cinema Tools did a fair job of removing the 3:2 pulldown from the 24fps clip, but not great. But on the 30 fps clip, I just used the "conform" button and told Cinema Tools to conform the 30 fps clip to 24 fps, and bingo--the footage now runs at proper speed, with "progressive" frames.

I want to tell the lab to telecine my negative at 30 fps (so I can conform it to 24 in Cinema Tools), and my mag sound at 24 fps (so I can re-synch in FCP without pitch change problems).

Is it really that easy, or am I missing something crucial?

Reverse telecine (pulldown removal) either works or it doesn't work. Only loss would be re-combining frames that were split into fields.
When you say 30fps I'm assuming you're transferring 1 film frame to 1 video frame?
In that case it doesn't need to be conformed, just marked as being 24fps. If it does think it's actually 30fps and going to 24fps then it will be dropping frames.

What's the difference between conforming and marking? The goal is just to take that 30 fps video clip and slow it down to 23.98 fps, not to lose any frames.

Yes, the telecine was run at 30fps, so 1 frame of video = 1 frame of film, so both fields of each video frame are on the same frame of film, so no pulldown.
