Dolby Vision now possible through MP4 Mux.

Can someone please tell me how to convert truehd atmos to eac joc with atmos?

[Gatorman]

AFAIK that isn't possible yet. The Atmos/Object metadata is always lost.

[pitrako]

Ah ok thanks for answering.

[Donpoku]

The ones done in cmv2.9 without trims, yes I always generate new/better cmv4.0 metadata.

The world of encodes is fascinating indeed. According to this guy W4nk3r has little credibility.

Btw I agree with you and would welcome a list of current top ones apart from your 3 of course.

[RESET_9999]

Yeah, I only list the ones that bake FEL or not and as far as I can tell, the w4nker release I checked looked like decent quality but I don't really care about encoders. I only care about releases that say REMUX.

According to this guy...

Anyway, I'm not sure about this guy's credibility. I do agree with some of his claims but there are no screenshot comparisons and he sounds like he's 12 years old.

it fails when it tries to convert to prores. I don't know why it does that for you sorry.

turned out the issue was me relying on the there being an AviSynth folder in the tools.7z package, once I installed avisynthplus the HDR10 conversion to DV completed successfully, albeit it took a very long time on my Intel NUC8i7. At one point I noticed a warning about no CUDA device being available, I guess the conversion had to run without much in the way of hardware acceleration? Is there anything I can do with settings to improve that, or is it a limitation of my not running a full PC rig with an nVidia GPU?

[RESET_9999]

Yeah, it's already very slow with a GPU, so I can't imagine how long it must be on a CPU. Your only other option is Resolve.

while it takes a while to convert an HDR10 source via the 3-1 workflow, the results from my first test seem well worth it. One point in this workflow that does not have an automatic option is the prompt for the Mastering Display choice. I'm using the values provided by MediaInfo, is that correct?

[RESET_9999]

yes

it's because I prefer selecting MDL based on the content's actual brightness.

[morbius]

you've done amazing work with the toolset, I was happy to make a donation. I just watched my HDR10 copy of Inception after it had been processed via the 3-1 workflow, and found it to be transformed. I've been quite careful in my picture mode configuration on my main OLED display to configure the settings for HDR10 using a Spears and Munsil test pattern, but even with HDR10 dialled in using that test, the DV conversion was so much better.

Is it the case that even with MEL, the DV processing by the display affects how colours are rendered, it's not just about shot-by-shot contrast?

[RESET_9999]

Yes, shot-by-shot metadata will have a bigger impact when the content is brighter than what your TV can do and Inception constantly peaks over 1000nits and it's quite a saturated color grade (too much in my taste).
When the colors are brighter than your TV capabilities, they can look slightly desaturated in HDR10. The generated metadata does not change the contrast and colors, they are just compressed better in DV because the TV knows the shot brightness in advance, it can compress the highlights and gamut much more accurately than a static tone mapping curve which is what you are noticing.

For content within your TV dynamic range, you wont see much difference with HDR10 (assuming your TV is correctly calibrated)

@RESET_9999

Any idea why I get this error when dragging HDR10 bluray version into 6-2? I'm trying to verify the HDR10 vs DV brightness of Kingdom of The Planet of The Apes 2024 before the transfer.

[RESET_9999]

Sometimes madVR fails to read the file and it usually happens with TS/M2TS files. It can happen with mkv files but it's rare. I had no issue measuring my mkv remux though so there might be something going with your rip. Anyway, I already verified this movie: https://slow.pics/c/XaJrQYFA

[deadchip12]

so there might be something going with your rip. Anyway, I already verified this movie: https://slow.pics/c/XaJrQYFA

Should I still use that rip then?

Btw, I just plotted my DV web version and the brightness doesn't look similar to the hdr10 pic you posted at all:

[RESET_9999]

mine has both, brightness measurement and dv plot.
