Not sure if anyone is interested, but here is some backstory on the how it came to be.

I was unhappy with the quality of the WMV HD titles that had been done. There was some pretty ugly banding...

Deluxe has been using it for Blu-ray encoding since 2007/2008. We gave them a DMO that we called xScaler with the algorithm(s) in it along with linear light scaling and they built an app around it...

The image I attached from BT.2246 actually had both stained glass and blue butterflies. :) I had not considered either before reading the doc. I bought some peacock feathers to measure. Beetles...

One will be a talking head scene, such as a doc interview with shallow depth of field. Will be interesting to see if very little motion still stands out with higher frame rate. My RED is all torn...

I was thinking the same thing! :) One idea that came to mind is to use multiple cameras next to each other and frame wide enough so you can shift images left or right and then crop. If you are...

While I might buy an HDR panel to develop HDR test patterns, I am hoping we get projection soon Because that is what drives my home theater.

There is no arguing that OLED has great black levels, but it is severely limited by light output. HDR will burn an OLED out sooner and it can't do full screen at the highest nit level, at least not...

I think Scott mentioned that some existing displays are going to offer FW updates to add HDR support. This probably just means they will add the PQ curve to the display.

I suspect that we will...

I have reposted most of it below, I did make some changes.


We have a 2015 Panasonic LCD at work that is edge lit. It "claims" HDR. It has a mode that is supposed to make SDR into HDR. The new...

I am not a fan of edge lit at all. I have two Vizio displays at home and I have turned off the feature because I can see the image fade up and down. I find it distracting.

One interesting thing is UHD Blu-ray, which supports 24, 25 (finally), 50 and 60. No 30, 48 and 120. 30 can be packaged as 60 by repeating frames twice. Its going to be the highest quality home video...

No worries. :) This is always an issue when talking about bits. Are we talking about BPP or BPC. If we talk about bits per pixel, it is 24-bits vs. 8-bits of BPC. :)

I think I will try and hire a couple of actors and shoot a scene at 24, 25, 30, 50 and 60. I think that would make for some nice demo material so people can see the differences. I will stick with 180...

30 would remove the 2-3 judder for sure, but it would also remove the look of 24, which is important to some. 24 to 30 does not sound like much, but it does look visually different. You can compare...

No. You could encode at 60p and then use some type of 2-3 pattern on the 24p portions to make it 60, giving it a bit of 2-3 judder interspliced with true 60p content.

You should take a look at some camera / film making forums, such as www.reduser.net (http://www.reduser.net) and see just how much people like the look of 24 and the associated motion blur.
