> due to the fact that 48FPS made it very apparent there was lots of makeup being used How does better temporal resolution (higher frame rate) enable better spacial resolution (see makeup detail)? In no or low motion, there can be no difference.

The HFR camera uses a notably different lens, I believe as a result of the faster shutter rate. When you double the fps, you halve the exposure time, which calls for a different lens.

There is never no motion, unless you're in hard vacuum or a clean room. If you doubt this, shoot some video of a static scene, then take on frame out of it and repeat it for the same length of time. People's pulse makes the color of their skin change subtly. Lights flicker in phase with alternating current. Outside, the air moves and the color temperature of the sun changes subtly with it, even if the sky is perfectly clear.

More updates per second to each pixel means each pixel is more faithfully tracking the real-life image, which in turn allows the eye to more accurately interpolate spatial details in the displayed picture. As you say, for a truly static scene there is no difference. In practise there is always noise in the picture, so even in static scenes a higher frame rate will tend to reduce noise by averaging.

> How does better temporal resolution (higher frame rate) enable better spacial resolution (see makeup detail)? In no or low motion, there can be no difference. Because you're not watching a single still frame - it's more like your brain is taking in an integral of visual information over time. You don't need much motion to be able to perceive a visual difference (even if it's just a 'feeling'). Eg. http://iwdrm.tumblr.com/ http://iwdrm.tumblr.com/
