"High Definition Benchmark" BD Edition by Stacey Spears and Don Munsil - Page 36

Based on your previous comment about the green looking like the lower right, it sounds a lot like 601 color conversion error. Do you know anyone with a VP50Pro you can borrow and try out?

Did you recalibrate black level after reducing contrast?

Larry:

Thanks for suggesting both of these things again. Apparently I just wasn't patient (i.e. smart) enough the first time around. I have gone back and found that I can turn Contrast down significantly (solving the red clipping issue) and that didn't impact the whites.

Stacey:

Having googled VP50 I can confirm I don't have one at my finger tips :-) I could probably hit up a guy I know at a high end shop. Since I can get the red squares to show up with a reduction in contrast would you still have the 601 issue in mind?

Good news!

Red and blue should clip around the same time. If you have to turn down contrast a lot between blue and red clipping, then its worth trying to get a VP50Pro to at least test with, otherwise you are turning contrast down too far.

Hello Folks, I've ordered the disk from amazon UK but still waiting for it to arrive. My goodness you guys are much more technical than me I hope that I can use it.

My disc gets frozen on the HD Color Bars/Sharpness area of the disc.

The BD is pristine. My player is a Pansaonic DMP-BD65.

I end up ejecting the disc and restarting to get beyond this point.

Has anyone else experienced this or have any ideas?

Thank you for your time.

For grins and giggles, use some warm water and mild soap and wash the BD face and see what happens. Can't hurt and sometimes it works.

What do you mean it gets stuck? Once you start playing the pattern, you can't go back to the menu?

What I mean, is I can hear the laser clicking, like it can't find the next track mark. The time shows all zeros, and if I push up arrow to show the help function, or the right arrow, track forward or pause, nothing happens. The only player function that seems to work is eject.

I have no other issues with this player with about 100 other BD's, so I don't think it's the player...

Also, the disc goes from the jewel case to the tray and back again. That's all...I treat my S&M BD With the Love and respect it deserves! :-)

Sent you a PM.

Testing frame-rate errors

Some receivers are known to have the 24.00 fps bug, in that 23.976 fps input source is output as 24.00 fps, and 59.94 as 60.00 fps. The latest culprit is the Onkyo TX-NR818. Some users have noticed it but not others. Until recently I confirmed it using a DVDO Edge to 'measure' the AVR's HDMI video output it remained only a suspicion that this is happening. In the discussion in the Onkyo thread we note no reviewer has found this bug and that very few devices can distinguish between 23.976 and 24.00 fps on their GUI info display and this isn't something that reviewers normally would measure.

I wonder if it's possible to devise some test patterns that more people can use to look out for this bug and this may be more common occurrence or more disturbing to some than the odd cadence de-interlacing issues which reviewers seem keen to test on players.

^ I think any sort of scrolling pattern should show that frame rate issue fairly clearly (if you don't happen to blink).

We have a stock ticker type clip on the upcoming disc that may help. We offer it at 24p (23.976), 30p (29.97), and 60i (59.94 fields per second).

Is there material on this disc that will help show if you have colour uniformity problems? I have a plasma with green/yellow blob in the middle and pink tinting issues on the sides. Usually most visible in grey, white and beige scenes. I don't always see it but I want to see if changing my calibration will change the blob/tinting to any degree.

Can I do any grey-scale calibrating at all without a colour measuring tool?

The 2nd edition does have a couple of uniformity patterns. Solid white field, black field, and then both with inverted squares in locations you should measure with a meter.

You can set the basic user level control that has options like cool, warm, etc... To adjust the bias and gains you need a meter or at a minimum, a gray card with D65 reference light, which I would not recommend even trying.

Here is what the case will look like.


It will not make it out this year since it is still in authoring. Once we sign off on a build of the disc, it will take around 20-days to replicate. 5-10 to get the check disc back and another 5-10 once we give a thumbs up to the check disc.

I want to just say that I'm super excited about this new disc, and I'm looking forward to hearing what people think about it. We managed to do some things people said couldn't be done with 4:2:0, like smooth single-channel (RGB) ramps that hit every level on the nose, and perfect monotonicity patterns. We rethought just about every pattern on the disc; almost nothing is just carried over intact. There are tweaks and adjustments all over. In addition to tweaking all the old patterns, there are literally hundreds of new clips and tests. And we think this may be the first commercial disc with stereoscopic test patterns on it, as well as a complete set of standard patterns encoded in 3D so you can do standard calibration while your display is in 3D mode.

^^^^ Cool, can't wait for the new disc!

We spoke with authoring today and we are targeting the end of January to be finished. If we hit this date, then the disc should be available in March.

We have also decided to create a scaled down version for DVD. At this time we are not sure if the disc will be bundled with the Blu-ray or a free download.

What do you expect the retail price to be?

That's a great question! We don't know the cost of materials yet. For example, the included booklet is longer. It should be priced similar to the original disc.

Hi,

Trying to get a copy of this DVD!

Any update on the release date?

And where are the first available copies going to be released from?....in terms of what retailer?

We approved the Blu-ray check disc on Friday. We hope to have inventory in three weeks.

It will go on sale at OPPO and Amazon first. If another retailer wishes to sell it, they simply need to contact us.

Is Amazon going to do a preorder listing ?

Hi Stacey - what is up with the pricing for the out of print disc? Zounds!

http://www.amazon.com/gp/offer-listing/B001UM29OC/ref=dp_olp_new?ie=UTF8&condition=new

It probably won't go on Amazon until it is in stock.

When the 2nd edition comes out, the prices on the 1st edition should drop.

Will you update this thread once it's available, or should we just check Amazon?

We will post. We are also launching a new website soon. Target is 4/22.
