Showing off content on new sets

[Peter Rollins]

I'm curious about the higher resolution progressive scan 60fps content being displayed on newer high definition consumer HDTV's with new technologies for better motion portrayal.

For example, can the candidate 720p120 be displayed on any of the new 120hz LCD sets? A perfect candidate would be the new Philips 1080p 120hz LCD set:

52PFL7432D

This set has completely solved the retinal blurring effects that all the other HDTV sets have, and it would be awesome to see high shutter speed 120fps content on this set with absolutely no motion artifacts whatsoever.

Demonstrating the ability to create 1080p60 or better discs for consumer usage that surpasses NTSC on motion portrayal at normal speed would be a huge deal for me.

I heard all the film guys (I'm a video game developer by the way) talking about high speed shutter as only a method of achieving 5x slow motion (IE: 24fps viewing is all that matters mindset).

But what about 1x speed with 5x the bandwidth of data streaming to the brain? Wouldn't this simply be more immersive than anything?

Just some random thoughts.

As a movie viewer rather than a movie maker, I might even go into a theater if there were 120hz action movies to watch. Most of the things I actually watch look better at NTSC's 60hz just because I have more temporal information at 1/10,000 a second and 60 fields in the lowly NTSC.

With all the other "we're the best" on resolution and bandwidth, why not also beat NTSC at it's only stronghold, and that is portrayal of high speed action. The action of football games is STILL better on an average NTSC set than HDTV because of sample-and-hold motion problems.

To add:

Most 120hz sets (besides one japanese model that I know of) don't do 5:5 pulldown, and only use 120hz to add an interpolated image to reduce motion artifacting by 50%

The above japanese set is the only one that I know of that actually does the 5:5 pulldown you describe unless you can point me to another one.


The speed of the display does not dictate the speed of the shutter. I understand the camera constraints, but my issue is with 24p 48strobe in theaters disallowing high speed motion without artifacts. Better displays in the theater and in home HDTV's would not interfere with the film look for content that wants to use lower shutter speeds for more light and better color, etc.


To the best of my knowledge, only Aptura aka ClearLCD and Laser Television provide the kind of strobing and image-per-strobe necessary to provide motion without temporal aliasing.
