FS7: 4K 25fps or 2K 50 fps for projection?

I would stick to the recording frame speed.
Why? Because in my opinion you would want to avoid decimating or duplicating let alone blending frames.

That is what I mean, 4K 25 fps, (with downsize I mean only change 4K to 2 K and keep 25 fps) or:
2K 50 fps.
What looks best on big screen. (while filesize remains the same)
If you're going from 25fps to 50fps your always going to be duplicating frames whatever process you use, so no I wouldnt go down that path. Edit for a 2k export @ 25fps.

Yes I would agree, the only exception would be if the 25fps is interlaced then frame doubling would be beneficial.
I think my question was not clear, I'll try it again (English is my third language so forgive me my mistakes.) It is not about changing framerate, I record 25fps 4K or 50fps 2K. I don't change the framerates.
What is better for projection:
Recorded in 4K 25fps and downscaled to 2K at 25 fps (and projected in 25fps)
recorded native 2K at 50 fps (and projected in 50fps)

I understand now.
For a city promotion I would use 24p or 25p. Unless you want to record sports or fast action there is no need for a higher framerate.
Welke stad?

Are you positive that the projector can really display 50 fps? If not, then you're wasting your time shooting 50 fps regardless of the resolution.
Thanks, Cary, Doug, not sure about the projector. Will be a hired one. But it makes the decision easier for me, 4K and 25fps will be the choice for recording...
The idea of 50fps was planted in my brain after filming slot car races with 60fps. These little cars are very fast. In slomo they seem to drive the proper speed. And the image is nice and sharp.

I'm sure I don't need to point out that there is a big difference between shooting 60/50 fps and playing it back at 25 fps for slow-motion vs. actually projecting a finished video at 60/50 fps. Two totally different uses of higher frame rates. So if you don't need slow-mo; and your project can't display at 60/50 fps; then there is no reason to shoot at 60/50 fps because half the frames will just be dumped someplace in the workflow.
Thanks Doug, I was aware of that.
I was glad I did 60fps because without slomo the little cars wouldn't be visible at all
Their speed is 15mph scale 1/24 (relative speed 360 mph!)
