Which processor on the market is currently the best at taking in a 1080i, 1080p60 and 1080p24 signal and transforming it into 1080p24sf (for the Sony Qualia)?

Ahead of any answers what would be the advantage since extraction of the 24sf from the source would be the desirable goal ?

Because the Qualia without the $3000 mod to add 1080p 60 digitally in, for digital (not anaslog) only accepts 1080p 24 sf in. At least that is what I remember.

Well, as I am looking for a unit to accommodate multiple HDMI sources anyway, I thought if I could output film at the 1080p24sf resolution that the Qualia desired, I could "kill two birds with one stone" so to speak.

Also, as the 1080p update for the Qualia does not do what I would want anyway.

The Qualia 004 when driven via HDMI or DVI, matches the on-screen refresh rate to the input signal refresh.

That is, when fed a 1080/24PsF signal the on-screen refresh rate is 48hz (thats the actual hardware frame rate of that signal)

When fed 1080/50i it refreshes at 50hz, when fed 1080/60i it refreshes at 60hz etc. Those (48hz, 50hz and 60hz) are the ONLY three input refresh rates the HDMI/DVI inputs accept. The Qualia does no frame rate conversion so what you input is what it outputs, screen refresh wise.

This has been confirmed by Sony engineering after I inquired and had the inquiry escalated far enough to finally get an answer.

So there IS an advantage with a Qualia 004 in using 1080/24PsF over even 1080/60p, even if your Qualia can do 1080/60p. You get 2:2 cadence for film based source material rather than 3:2.

The Qualia treats 1080/24PsF as progressive, and displays it at a 48hz on screen refresh rate, holding each input frame for 2 display frames.

Now the question is how to get it a good 1080p24sf signal when everything is planning on outputting straight 1080p24!!!

Help!

The lumagen outputs a clean 1080/24PsF signal from interlaced source material. Film sourced material sent at 1080/60i creates a pretty much flawless 1080/24PsF signal.

It has fairly poor video deinterlacing however, but they are scheduled to release a new processor that has much improved video deinterlacing and should provide the same level of performance with film sources at 1080/24PsF.

I suspect the VP50 will probably add 1080/24PsF output at some point as well, and I think the Crystallio II either does it now or will soon.

I'm in the same boat as Peter S. with my Qualia 004. I have heard the Crystallio II can handle the 1080p24sf, but it was initally reported as being a little "rough". Has this improved? Any other processors I should look at? Thanks,

Any new options out there for this conundrum?

As more of us 24psf PJ owners get 24p players the demand must be increasing for this capability. Would it be that costly to incorporate segmented frame in a mid-range AVR with todays processor tech?

Lumagen just announced that they will soon be releasing an update for their radiance processor that will convert 1080P24 to 1080P24sF.

I have a Qualia (and a Lumagen Radiance)....So, I am quite anxious to get this!!

how does 1080p24sf differ from 1080P24?

Uses 1/2 the bandwith by segmenting the frame into a 48i stream. The display then reconstitutes it to the original 24p.

We have many customers who use the Lumagen HDP, ProHDP and HDQ to drive Sony Qualia projectors at 1080p24sF. We will be adding the 1080p24sF output resolution to the new RadianceXD very soon. We have heard from some of our Radiance customers with Sony Qualia projectors. They are looking forward to having this resolution available.

Best regards,

Uses 1/2 the bandwith by segmenting the frame into a 48i stream. The display then reconstitutes it to the original 24p.

It's the same bandwidth. It's not like NTSC where the interlace is used to send two 60hz half bandwidth images to equal a 30hz image. In fact 24p of 24sF has a lower bandwidth than 60i or 60p. You can put 25% more material on a given storage system at 24p than at 60i or 60p. The 24sF signal is actually padded out to match 60i so system timing clocks remain the same

The sF was designed to maintain compatability with 60i systems. In the late 1990s the split between 1080i and 720p between the four top networks threatened to stall HD deployment for years. What was Hollywood who feeds all the networks to do? Install duplicate facilities foir 1080i and 720p on this new thing called HDTV many wall street folks were perdicting failure financially?

Laser Pacific Media Corporation who at the time was one of the sole production and mastering facilities involved with the studios for HD developed the 24sF format. This allowed 24P video to be processed by 1080i equipment with minimal modifications. Laser Pacific holds two engineering Emmy's for 24p developement.
