Also, that Dan Curry shot his FX work with 30 fps. Why exactly did he do that?
To avoid 2:3 pulldown on NTSC video. This is actually a question I submitted to XXXX and he graciously included it (thanks XXXX!).
When film is shot at 24 frames per second it has to be converted to be shown at 30 (29.97) frames per second on broadcast television in the United States and other countries that use 60Hz frequency. You can read more about that process here
. Dan Curry decided that in order to make everything simpler for him and his team back in the eighties and nineties that they would just shoot the miniatures at 30fps and no pulldown would be necessary in the video realm.
Now, 25 years later, CBS Digital and Illuminate Hollywood* have to speed up all those shots Dan Curry supervised because if they didn't they'd play 20% slower at 24fps and all the shots would run longer than they're supposed to.
So, as you can see, Rob Legato was actually quite forward thinking in his decision to stick to classic 24fps.
* As is mentioned in the TrekCore article, Dan Curry is actually now working with Illuminate Hollywood on the Season Two VFX.
