There is a fantastic scource of knowledge here, and I've read and browsed for the last few days learing shed-loads of answers to many questions I had in my head about this amazing new camera, with nowhere to ask them untill I found the site. But there's a few fuzzy bits I need clearing up.
I'm asking this from a slightly different angle because my primary work is Shake Film compositing, so my work is nearly always on a 24fps timebase. I want to shoot elements for shots I work on for small budget films. I'm being asked more and more for 'pooling blood' or blood splats, small explosions, smoke, skys etc where there are no provided elements. It can take days to beat something into shape from some 'almost alright' library footage (at a cost), or elements from some previous film that have gone into your library. I could shoot something in a few hours in a small studio.
I do lots of retiming work aswell with Twixtor and PFTrack, so elements shot at 60fps are a better starting point for really smooth retiming of elements than 50fps. More frames the better. PFTrack also allows me to 3D matchmove footage I shoot into either Shake or Lightwave.
This is to be my first video camera, (although I've been doing my own B/W and colour 35mm for 20-odd years with Canon F-1s and the like), but my interest doesn't really fall into shooting for television work, so I'm not really interested in the PAL side of framerates.
But I live in London, so I was very interested to read the threads with PAL and NTSC framerates relating to the power-phasing in the mains electricity, to be balanced with the fact that all you have to be sure about when shooting NTSC here is to choose a shutter speed that's a multiple of the Hz, ie 1/50, 1/100 etc. Is this all I need to worry about, or does shooting at a 24fps timebase nullify this?
If I shoot all my footage on a 24p timebase with an NTSC camera, is this close enough to the 50Hz phasing here to not matter, or will I get a flicker drift of 1 frame a second?
thanks for all the knowledge so far, and I'd appreciate any advice people might have.
