House,MD is shot on 35mm film with Panavision Cameras, but it seems to feature HD cameras for "B" & "C" cameras. Here is a bts video of house with the hvx200 actually being used:
I think that you will find that most network shows, made for TV features and national TV commercials are shot at 30fps, not 24 fps, whether shot on film or video. The reason is to eliminate the 24fps to 30 fps "hiccup" that occurs in transfer to video (only). The 24p effect for video is generally an attempt to emulate this 6th frame double printing of the 24/30 transfer. You don't have the "24p" effect when viewing a film theatrically, only when 24fps film is transfered to 30fps video for TV presentation, and that is a visual disruption that high-end producers don't want.
24p was originally incorporated into video cameras in order to allow for frame-to-frame video to film transfers, not to create a "film-look" effect to video. 24fps is used in film production for theatrical release. 30fps is generally used for high-end TV release.
I work for a small production company. We shoot mostly tv spots. What do you recommend to shoot in to get a filmic look but be compatible with TV broadcast?
Our typical setup:
Shoot in 720p 24p on HVX-200
Drop 720p 24p footage into identical timeline in FCP
Convert that sequence of footage to 4:3 SD 29.97 DVCPRO QuickTime files
Edit from the "transferred" 29.97 files
Output to DVCPRO tapes for delivery to TV stations
