Dolby Vision now possible through MP4 Mux.

Otherwise, it depends on whether the cmv2.9 rpu has trims or not.

Could you elaborate on this? Which workflow to verify the web rpu has trims that the bluray does not?

[RESET_9999]

(6-4) to plot the trims

hallo reset is it good enough SEVEN with freman and pit from framestore hybrid 8 profile dolby vision or it s aggain fail from the framestore group and it s in cm4.0 or cm2.9 ?

What exaclty should there be?
I used on workflow 6-4 on the example mentioned below (P8 Remux) here are the results:

If you have a few can you please take a look and myabe point out exaclty what should I look for and if this is worth of transferring genarted metadata?

Also how do I verify if FEL was baked in?

ps hope my questions will get less annoying once I start getting it

it looks ok.
cmv4.0

You can never transfer a generated cmv4.0 block into an original/retail cmv2.9 rpu
if the original cmv2.9 doesn't have any trims (or static ones), then you can completely discard the rpu and inject your generated cmv4.0 rpu

Also how do I verify if FEL was baked in?

compare the encode with the original P7 rip in 7-2

Sure, but what should I look for in my example. There are PNGs with L2 titles and there's some stuff in the graphs. Are those the trims?

[RESET_9999]

When 6-4 creates trims plot graph image(s), then yes your input contains trims...
if the graph is a straight line (like the Harry Potter movies), then it has static trims and you can discard the original RPU and use the cmv4.0 generated one.

So this Se7en framestore release with DoVi cm4.0 is actually better in terms of quality when compared with the HDR10 cm2.9 uhd retail bluray ?

Well, 92% of the movie is under 600nits so pretty much all the TVs will be able to display it without tone mapping.
It shouldn't look much different than HDR10 playback unless you have a very low brightness TV/PJ.

The trim has a positive lift over 0.0025(2100) for the whole movie but it is ignored by all the HDMI devices.

Thanks a lot for your reply!
"Unless you have a very low brightness TV."
I have a LG G1 OLED. That should be fine I guess in terms of brightness?

[RESET_9999]

yes

Thanks for the answer. That clarifies a lot for me.
However when I plot a cmv4.0 there are no L2 trims being created but the L1 Plot list it. Are those produced from L8 now and is it also backwards compatible with cmv2.9 devices?

I'm pretty late to the party, but what is your guy's suggestion to a Samsung TV owner with only HDR10plus available?

Is it even worth getting something like a Ugoos AM6B? I'm currently using an Apple TV 3rd gen with Infuse.

I mainly download and occasionally rip some UHD Blu-rays.

[RESET_9999]

Yes, the ugoos supports DV + FEL(LLDV) on any display (SDR/HDR10).

However when I plot a cmv4.0 there are no L2 trims being created but the L1 Plot list it.

All the original/retail CMV4.0 rpu will have L2.
I just noticed the latest script version has the L2 trims plot disabled by default. So re-enable it at line 185

:: plot cmv4.0 only in 6-4. This disable L2 plot (default = NO)
set cmv4.0.only=NO

Have you had a chance to test Davinci 19.x to see if it's still necessary to decode to prores first? Has their hevc support improved at all? I finally was able to fix my Davinci working with their support and I want to start playing with DV conversions soon. Thanks!

P.S. Apparently when I installed the pre-reqs for DoVi Tools, the version of Python that got installed from the Windows store broke Davinci and it was no longer able to start. Throwing that out there as a warning for anyone else who may run into that issue. I will need to solve the Python version issue before I get too far.
