16-235 is a typical NTSC luma range. PAL always uses 0-255 luma range. But that may prove difficult with the FPS you require.

I understand that. That is why I said that this is a specialized requirement. I need to be able to author an NTSC Blu-ray with a 0-255 range. Is this even technically possible in Premiere?

I'm not sure a 0-255 luma range is even legal for NTSC BD. Look that up in the Wiki, but I have my doubts.

as far as I know Bluray NTSC nor PAL profiles will use full range for AVC-1 encoding...

(and there is no setup option in Adobe Media Encoder for that)

but you can setup the Bluray players output to fullrange RGB at least on the better ones...

it's a very uncommon need to encode a full range 8Bit signal - can you explain why you need this?

If you are looking for high quality a 10Bit video system could do the job?

Yes, it is uncommon. That's why I described it as a specialized need.

I am creating a disc that people can use to calibrate their displays to the proper levels. For this purpose, I need to be able to author test patterns that show below black and above white. Although 15 and below and 236 and above are not used for normal video content, they are routinely used for this purpose. There are many such disc on the market that do this, and they have used SOMETHING to author the discs. I am just trying to figure out what that is.

You could use x264 as the encoder, with the --fullrange switch. If you don't want to go through the hassle of doing the command line script, you can use it through MeGUI, but you will also have to learn how to use it, though it's not difficult.

Hi Tom,

I am creating a disc that people can use to calibrate their displays to the proper levels...

ok - I understand... complex thing because there are so many devices included that can alter the signal...

1. If I have to send a testpattern for calibration to da display I use a PC or a Mediaplayer in Photo-Mode propperly configured to output full range signals.

(Would be realy helpful to use something like a BMD Ultrascope to check the signals at HDMI level)

2. In a typical home cinema env. you have to consider:

a) Bluray player - is it configured to output fullrange? Even if you get managed to author a AVC-1 video stream containing full range signals - how will the decoder of the bluray player deal with this??

b) Routing the signal through AV receiver - is it altering the signal levels??

c) TV - how is the input configured - are there filters active to "improve" image quality - or to say the truth: is there anything active in your TV to destroy the carefully mastered video signal??

--> The 4:2:0 scan raster of a Bluray AVC-1 stream in general is't the best way to store test patterns at all... so a data mode disk with some PNG's are the better choice??

What do you think?

@ Sebasvideo: No problem to encode a full range AVC-1 stream but how to author a standard conform Bluray containing the full range signal if the standard doesn't support it?

I think that this is what I need to do. I have high-quality static images. I just need to get these onto a Blu-ray disc much like you would create slideshow. I just don't know how to go about it, what tools to use and what options to select to enable the 0-255 range. When I use standard commerically available tools for this--Nero is an example--it compresses everything into 16-235.

Hi Tom,

I would author a normal video bluray with Adobe Encore - add some instruction videos and background how to's via sub menus and finaly put the testpattern onto a extra computer data partition of the bluray (you can add this in Encore to your project easily)

But you have to tell people how to check the Bluray players video output setup and all the like on the video bluray part of the disk...
