Master in 24P or 23.976?

I understand that '24P' seems to be shorthand for 23.976, but premiere, after effects, and virtual dub all have settings for both 24fps and 23.976.

I work with video and animation, and have to create a master to can be converted to NTSC and PAL dvds. Most everyone agrees to start at 24 fps, and then apply the appropriate pulldown for NTSC or PAL at the last step in production. But do they really mean 23.976?

Thanks in advance,
Jason

24P runs at 23.976. It's like saying 30 fps but really it's running at 29.97. Even if you use the 24P presets you'll be dealing with footage at a 23.976 frame rate. Well, if you want to get really really deep it's actually a 29.97 data stream but the frame rate of the 24P footage is 23.976. Use either one and it should work fine.

video & HD ( up to 1920x1080) 24p is 23.97 ..

however 1k/2k/3k/4k scans are 24fps progressive. if you are going back out to film then any rendering would be done ( uncompressed) with speed set to 24fps progressive ( sometimes listed as 24 film) .. you would also set NLE time line to 24fps not 23.97 ... note that any rendered clips at 24fps most NLE's will see them as 24fps not 23.97 .. you can create 720x480 ( uncompressed only) 24fps or 24p ( 23.97) clips ...

if you are creating CGI for ntsc or pal you would use their properties .. if you are creating CGI for FILM then you use 24fps progressive unless they give you the film elements transferred on video or hd ( 29.97/23.97)... most CGI for film out is 24fps not 23.97
