1080p/24 doesn't work according to CNET test

While testing the BDP-HD1 with a 1080p/24 display. Jeffong, looks like you don't have to wait for a 1080p/24 display any more.

 

"Moving on to video quality testing, we were excited to test out the BDP-HD1's 1080p/24 output, and luckily we had the Pioneer Pro-FHD1 on hand. The Pro-FHD1 one of the few displays capable of accepting a 1080p/24 signal, and it can also change its refresh rate to 72Hz. Technical details aside, the supposed benefit of this combination is that the 24fps output paired with a compatible display can decrease judder.

 

Unfortunately, our testing seemed to reveal that this combination did not yield the expected results. In the beginning of Chapter 4 of Corpse Bride, there's a slow pan down over a window. With the Pioneer BDP-HD1 in 1080p/24 mode (called "source direct"), with ADV set to On for the Pioneer Pro-FHD1, we saw more judder on center window bracket than in 1080p/60 mode with ADV set to Off. It's not a night and day revelation--there is still some judder with 1080p/60--but after observing several movies in both modes, we definitely felt that 1080p/24 increased the amount of judder we saw, instead of decreasing it. Similar behavior can be seen toward the end of Chapter 4 on Aeon Flux on the bottom edge of the white building, as well as on Tears of the Sun, on the tail of the jet aircraft on Chapter 1. This is disappointing; we were looking forward to seeing decreased judder as it is a frequently occurring artifact that can take the viewer out of the movie experience. Unfortunately--at least with this combination--1080p/24 didn't deliver. We didn't have any other displays on hand that could accept 1080p/24, but we'll update this review after we check out the BDP-HD1 on Sony's VPL-VW50 projector in the next couple of weeks."

Hope the Pearl can make it

Its not about whether the Pearl can make it, but whether a *specific player* with the Pearl is able to take the 1080p encoded on a Blu-ray or HD-DVD and get it to the phosphor, LCD, Plasma without jitter. Judging from some recent threads on AVSforum, this may be something quite difficult to achieve and we might not see full compatability at 1080p/24 for years to come. Somewhere along the line, you might be able to get a specific combination (probably from the same manufacturer) that works. Note that you will also need a working HDMI 1.3 receiver unless you plan on plugging directly and you are not likely to see the first versions (let alone any that work properly) of these receivers until 2H07 in the U.S.

I think the issue is because we don't know how the player or the display handles 1080p24.

 

I understand the HD DVDs use 1080i to implement the pop up menus and other iHD features, even if the main feature/movie is in 1080p24, so there is a bunch of conversion in place.

 

Secondly, we don't know how the display (in this case the Pioneer) handles the signal. Does it reprocess it to 1080p60? (that would be tragic).

 

Doesn't the Pearl have a "native" refresh rate of 96Hz? That shd be a direct multiple of 24fps. That may be the right formula.
