Ok Sooo I didn't know for sure what category this question best fits under so I chose Cinematography just to see....

Well I want to film a little short using model space crafts that I made - but I have never done this before - I have a general idea - along the lines of Star Wars - but I only know to use a blue screen and how to chroma key the backdrop out - but I was wondering if anyone had done this before and could give me some tips on shooting the models and angles and movements ect? - Any help would be great thanks!

make sure there are no wrinkels in the screen, make sure it is evenly lit, have your object at least 8 feet away from the screen, and light it seperate from the screen, not sure what you are shooting with each camera needs its own settings. I've never actually sed a blue screen but I almost live on a green screen, but the lighting concepts are the same, make sure you don't put any ctbs on your object lights,

good luck.

So if I use the 1/400th/sec shutter screen for filming ships fly by ect. - Should I also film in 24fps? Because the frame rate has to vary according to the articles above - so how do I adjust the frame rate to over 100 fps or whatever it is? - or should I just film in 24p and then slow it down or I guess I don't even quite understand how that works?
 
You cant do more than 25fps with a DVX. If you slow it down with optical flow retiming the fact that its 24 or 25fps makes no differnce. Best to shoot it the highest thats available to you, then stick it into motion and do some optical flow retiming like eric shows in that video i posted...
 
I'm not familiar that much with DVX100 models, but can any do progressive 30p (29.95) fps? You could then take that down to 24fps and get a very *VERY* small slow motion... no?
 
Mm what you really need is this monstrosity of optical technology:

Love using that thing, everything it shoots is staggering...
 
if you don't need motion blur, consider stop animation, carefully moving the spaceship a tiny constant amount each frame.

It depends on the shots you need though - have a look at my zero budget Star Vars http://www.youtube.com/watch?v=FRG5UZycBqA - although the scrolling backgrounds were shot live, the spaceship itself is simply several stills being moved around the screen via my NLE (Vegas)
