maybe someone can tell me before I go in and have to figure it out...

In the render engine you can set the framerate to whatever you want regardless of the framerate in the Timeline.

When I was doing my little brainfart (see the "Shootme" thread) I noticed that even though I had a framerate of 12 in the timeline, and the framerate of 30 in the render engine, the frames rendering in the render engine had objects changing position every frame...

This leads me to this conclusion: that regardless of the framerate you've got your timeline set to, it's the framerate in the final render that matters, therefore the fiinal render framerate ignores the timeline for that purpose, calculationg camera position and animation independently of the Timeline framerate...

Is this true? Does this therefore MEAN that I can animate at any framerate I'm comfortable with, and render it to the framerate that's necessary for the job without having to worry about it?

I just want to say that I too would like to know, I'm getting the impression it's mainly for reference. I tried duplicating a 45 degree shutter effect way back when by making drastic differences in the two. But now that I know how that works in film I don't think it could be done in engine without serious blur management.

I think it helps if you get to a point where you want to change your mind about the final output. Take emitters for example, since the timeline is seperate you can change the frame rate in the render settings without it messing up your emitter times. If they were connected then doing a project, deciding you wanted a different output rate and then changing it would also necesitate you going back to tweak emitter setting for speed.

Wouldn't it?

The render and timeline framerates are independant. Ie you can make your animation at 30fps for NTSC, but later might want to render at 25fps for PAL, 24 for film and 15 for the web.

CINEMA 4D will simply interpolate between these. So yes you can animate at 15fps and then render to 30.

imashination, I'm gonna test this tonight... the only thing I'm iffy on is this...

If I double the framerate, does it also halve the position of the camera in those extra frames?

Off to find out :D

Aye. It might not be as smooth and flowing, hence its best to animate at the highest framerate you might need.

usually what I do is animate at 12fps and then do an auto re-time frames...

Haven't figured out auto-retiming in Cinema yet...
