Yes, planning on adding an alternate A/V sync pattern for a device designed to measure A/V sync. Thank you for the feedback.
The current AV sync is available in both DTS-HD MA and TrueHD lossless. Planning to also support Atmos and the DTS equivalent on the next disc as well. Have not looked into at this time though, so I don't know what I can and can't do with the Atmos style audio yet.
No plans to support PCM at all. Its such a huge waste of disc space. We wanted to include the Montage in both Dolby and DTS, but we ran out of disc space on a single layer disc, which is why the montage is only in DTS-HD MA. I felt bad as I have always had a good relationship with Meridian and wanted to include TrueHD. Since I had to make a choice, I had to go with DTS since it was the dominate audio format on BD at the time.
Will probably include SDR and HDR A/V sync, in case that matters. Only planning on UHD, but if enough people want it, I could also include 1080p on the AV sync. There will be no interlaced on the next disc, of course, so no inverse telecine test content. There will be scaling patterns at the various resolution.
Will be looking into FALD type of tests. Not sure on it yet.
On the current disc, we use the left eye for 2D. I can't use HDR to make SDR on the next disc. At least for test patterns, its not the right thing to do. Not sure if I can have an SDR/HDR option like I do for 2D/3D or if I need to make it two discs with one SDR and the other HDR. Then for SDR, 709 or 2020 for UHD? I am planning 2020 for SDR, but would like to know what people think for UHD SDR.
There will be other discs out before ours, but we want to try and get it right. Still so much to understand on HDR. Biggie is metadata. Since it is hard coded, I need to figure out what levels I should target. e.g. 1000 nits, 4000 nits, 10,000 nits. Its all so complicated.
I have already started adding a place holder to our pattern generator to sepcify HDR or SDR. This mostly changes the levels. e.g. The image cropping pattern today uses 50% gray for the background and 100% white for the markers. The HDR version will actually use 50 nits for the background and 100 nits for the markers. A lot of basic patterns will be like this. I will use 100 nits in place of 100% for various things.
The SDR window patterns will be equal energy. The HDR window patterns will not be equal energy. They will be 10% area window on a black background. This goes back to the two disc possibility, which can get expensive. Still want to target 29.97 as the price point. Next price would be 59.94. I like to use video frame rates as the price.
23.98 is too cheap. I think 59.94 is too much and 29.97 might not be enough either. Won't know B.O.M. cost until we actually get everything authored.
To give you an idea, we spent just over $30k on authoring alone with the 3D disc. Since I encoded 99% of the disc, that was simply my time. When HD DVD and BD first started, encoding was around $100 a run time minute. That was just encoding. So a 90-minute movie was around $9k just to encode the main feature. I don't know if they charged for segment re-encoding or not. No idea what they charge for UHD encoding or authoring yet.
