I thought all the EU 100Hz TVs already did that, and they've been around
for ages.

It also helps with the viewing of DVDs movies. Movies generally go at
24 FPS, so the number of frames to be interpolated is constant. With a
frame rate that is not a multiple of 24 (such as 60, which is more or
less the NTSC rate), some frames get played twice and some get played
three times. The difference is noticeable to some observers.
Regards,
John

I've seen experiments where they filmed big-screen movies at 60fps, and
people would literally fall out of their chair when watching a movie
filmed from the seat of a rollercoaster.

They have at least "copy this part of the screen from here to there",
but I'm not sure if it's "motion" as such or just what is used to better
compress images with moving parts.

I've seen that happen - along with motion sickness. More common in a
domed theater (or an IMAX theater, but I think it's more common when the
picture is all around you).

I've seen limited effects like this on computers, but since I've never
really had a "high end" gaming rig, I haven't experienced it in a full
scene myself. I think the highest frame rate I ever had was ~60 average
(~75 peak).
From what I hear, though, >90hz is where things really take off.

Anyone remember the Brainstorm movie?

Very cool film. Highly recommended.

But when you have a sample-rate 4x higher than the data, blurring makes it
look nicer. See bi-linear filtering on 3D cards...

Only for the high-definition discs, DVDs are hardcoded to the NTSC or PAL
spec and the 24fps is altered prior to pressing.
