24P for U.S. television? at DVinfo.net

fargogogo · October 14th, 2002, 01:01 PM

I just ready an article that talked about shooting 24P for domestic television shows. Can anyone tell me why? Do 24 progressive frames converted to 30 frame interlaced add to the "film look"? Or am I missing something here?

Thanks.

Film is shot natively at 24 fps progressive, that is, no interlacing. When it is transferred to video for NTSC TV broadcast it must be converted to 30 frames interlaced (60i) via a 3:2 pulldown, and that gives it a "film-transferred-to-video" look. Actually it isn't a "look," that is what is really is.

If DV video itself is shot at 24p than converted and shown on an NTSC television, it is a rough equivalent to the look of film transferred to video tape. This can also be achieved by de-interlacing 60i video footage to either 30p or 24p, where 24p has a little more of a standard film-look to it. It looks like 16mm film as opposed to 35mm. Depending on the care taken during shooting, it can look like a really good 16mm transfer to video. It looks even better when shot on HD, more like 35mm transferred to video.
