I think you address two main topics here. First the 3D issue. I'm not the
psychiatrist from Twin Peaks who wears 3D-glasses usually. 3D is a hype that
occurs every some years and disappeares soon. The other issue is the increased
frame rate. As all I learned the human brain is only capable to recogise a frame
rate from 24 to 26 per second due to individual differences. So 48 frames per
second must be like looking at a wheel recorded with the usual lower frame rate
but being a little bit faster. I think you know this effect.
Best regards,
Michael

For the past several months, my PC has been running day and night,
rendering a large animation.
Initially when I looked at sequences rendered at 50 FPS, it looked
weird. It looked wrong - like it was playing too fast.
However, several months later, I can honestly say the 50 FPS sequences
look perfectly normal, and the 25 FPS ones look jerky and juddery. So
yes, I think it's just a case of what you get used to.
Given that 100% of all video you will ever watch is at low framerates, I
guess this problem won't go away any time soon.

PS. Where the hell uses 24 FPS? I thought everything was 25 FPS...

Movies. All of them. Everywhere in the world (AFAIK).
25 fps was the effective framerate of the old European analog TV
standard (50 fps interlaced), probably chosen due to the 50 Hz mains
frequency. The US never had 25 fps anywhere - their analog TV standard
had 60 fps interlaced (30 fps effective).
Fun fact: On European analog TV, it was customary that movies had a
slightly shorter play time than in theaters. Not because they left out
anything, but because for practical reasons they played them back at 25
fps instead of the original 24 fps. (In the US, the customary way to
adapt the framerate was to show each original frame for 2 or 3 half
frames, alternatingly, resulting in no change to the play time.)

29.97 IIRC, "officially".

Just to clarify: By "old European analogue TV", you mean the thing they
only switched off a year or so ago, and which is still the standard
framerate for (at least) region-2 DVDs?

Just use the terms "PAL" and "NTSC". Easier that way.

Well... there was also Secam & Nicam... (nicam introduced "stereo"!)
And for the place here, now it's, for DVB-T: mpeg-2 for free
STD-resolution, mpeg-4 for HD-resolution & pay-with-decoder
STD-resolution...
STD: 720i, I presume.
HD... something like 1080, i or p ?
Not counting the "overscan" of the display, boosting the frequency to
100, 200 or even 400Hz... or something else like 120, and the eventual
support of 3D (not for air-broadcast... yet ?).
Some movement's compensation are even run at 1600Hz... when the display
hardware is natively at 200Hz.

can't wait to watch it, but only after I get my kid to watch "Wreck-it Ralph"
(or actually she gets me to watch it :)
I've got no 3D issue (even with glasses-free gaming on 3DS) and have been
watching lots of 24fps movies "upscaled" to 48fps or more in a modern 240Hz or
something TV set, so I don't think I'll see the issue. when I watch it, I'll
post to tell you guys how it went...
BTW, my sister used to tell me the new TV made movies look like mexican soap
opera... I quite remember some of these having this distinct kind of movement.
I'd say, more natural and life-like...
BTW 2, can it be indeed a problem with projections running the feature film a
bit faster to some other standard? like old B&W Charlie shorts that look like
everyone was on speed?

Unlikely... old B&W might have been at 15 or 18 fps, so of course
playing then with an engine at 24 (for 18) was already a bit of speed.
The speed-up of 48 to 50 is unnoticeable (or all the European continent
is used to it, it's the same as 24 to 25).
If the display was 120Hz, it could be that instead of a nice 5 factor
(for 24fps), it is now an alternated 2 & 3 fixed images per frame.
(assuming no interpolation occurs between the frames). That might have a
bit of detection by some eyes/brain.
