Questions about time lapse/tilt-shift

I'm about to make a time lapse-movie. But suddenly I ran into some questions I don't find any answer to, so I'm hoping you can help me out.

1. Is a tilt-shift always exported in 24 or 30 fps? Not 10 or 15? And what's the difference if I shoot 4-5 fps?(it just goes in more normal speed with 10 fps?
2. Before I start shooting, I have to decide what frame rate I want, because if I want 24 fps I must shoot 24 pictures in order to get 1 second. If I decide to go for 10 fps, I'm good with 30 pics for 3 seconds clip. I'm I right? It seems logical, but I can't think at the moment and I can't find any answers out there.
3. If I go for export in 24 fps, will the video go faster the slower I shoot? If I shoot 2 fps the movie will go faster than if I shoot 5 fps?

I think I got the answers in my head, but I just need confirmation, because I can't decide what is what...

I shot a 2 second star lapse some months ago, and I think the stars was moving very fast. I guess my interval between shots was to long. Right?

you're a bit lost in all that back'n forth ..

1) you have to calculate 'backwards' - what is your playback frame-rate? In the US, 30fps is standard.- 24fps is/was habitual frame-rate in the cinema business. Outside US, 25fps is standard; any fps below 18fps is noticed as 'stutter'; HFR ("The Hobbit"), 48fps gives a very smooth playback, some notice as 'too smooth/electronic' perception..........

2) to create a real-time video, you need a recording of 30 frames per second…-

3) when you record just 15 frames per second, your 30fps project will playback this with twice the speed: it takes 2 seconds to record 30 frames,but are play backed within 1 sec.....

4) when you record every minute a frame, it takes 30min to record 30 frames; this half-hour recording will be play backed in 1 second...

5) so, rule-of-three: of you want to show a 3h process in 10 seconds, you need a) 10sec x 30fps = 300 frames, b) 3h=10.800secs/300=36 .. c) you have to record every 36sec a pic ...

6) in this example: if you record every 18sec a frame, you result in twice the amount of pictures - in the same time, this will result in twice the speed.

7) think of your video as a film-strip with 'empty boxes': how long is your final film and what is its frame-rate = this defines the amount of needed pictures; the time needed to record all these frames, defines the speed of your video: if you record all needed frames in less than the final video, you get a slowmo; if you record in twice the length (min:sec) of final video, you get a 50% slowmo ......... etc etc

8 ) the tilt-shifts I've seen do a different trick: animation movies do NOT show a new frame every 1/30th sec; they do show 2 or even 3 frames the same content = a 15fps (or even 10fps) playback BUT within a 30fps timeline - this results into 'stutter' we all know from all sorts of animation movies .....
