Selecting frame rates in OBS

I am using OBS not for streaming but for playing back videos/films via fullscreen projector PGM in a little community cinema at my home town.
And when doing so I have to deal with a wide variety of frame rates.

I just want to share the information that when using 24 fps (Settings/Video) as a common FPS value in OBS this in deed results in 23,98 fps
This of course is correct, because the NTSC norm uses the factor of 1/1,001 for historical reasons.

But for those who are not familiar with these "old analog days", it might be a bit confusing that 25 fps PAL is 25 fps but 24 NTSC is not 24 fps.

When you want to set up exact 24 fps you have to use fractional fps values with 24 as numerator and 1 as denominator.

Perhaps it would be a good idea for clarity for the OBS developers to change the common fps value to exact 24 (when selcting 24 - without the addendum NTSC) and leave the 23,98 fps to the fractional fps (24000 as numerator and 1001 as denominator) for special applications.
