Dolby Vision now possible through MP4 Mux.

Life is busy, havent been able to monitor the development of DV. Can someone explain why is it a big deal CMv2.9 vs. CMv4.0? I see the latter mentioned a lot here. I read the official document, but dont understand why its a big deal. Thanks!

CM v4.0 provides creators more control over tone mapping, thus it's more accurate when applied properly.

Hi everyone, I'm using cm analyze to calculate MaxCLL and MaxFALL values of a video file.
Unfortunately the cm analyze process gets killed randomly during the measurement thus, making it freeze forever. It must be a bug related to cm analyze itself. Has anyone else experienced this problem when using cm analyze?

Here it is a brief log:

Code: Select all

Drag and drop your file: C:\Muxing\500.Days.of.Summer.2009.WEB-DL.2160p.HDR.mov
Set the Image Aspect Ratio: 2.4

yeah, I have the same issue on my Windows 11 PC. I can no longer use cm_analyze, it crashes after about 10 minutes.
Are you on Windows 11? I spent a couple of hours trying to debug it and nothing worked so I suspect a recent Win11 update caused this bug because I'm using the same Nvidia drivers on my Windows 10 PC and there's no issue.

PS: You should use madVR instead anyway, it will be 10 times faster, and no need to convert to prores.

Yup, I'm using Windows 11 latest release:
OS Name: Microsoft Windows 11 Pro
OS Version: 10.0.22631 N/A Build 22631

How can I use MadVR to do that?

[RESET_9999]

you measure HDR with madMeasureHDR.exe and it will tell you maxcll/fall. You can also use workflow 6-2 in dovi_scripts which use madvr.

Code: Select all

madMeasureHDR.exe input.mkv

Thanks for the info. I'll use your script so that I can exclude black bars from the measurements.

I have both LAV filters and madvr installed, what's happening here?

[RESET_9999]

yeah for some people, cropping doesnt work and i don't know why.

It works now, I uninstalled and reinstalled both LAV filters and madvr. The problem was probably due to an outdated version of madvr.

2- Windows Energy Player

whatever problems watching at the computer/windows platform aside - is that the best windows store dv player then outside of any official dv pcs player etc?

and it's only because I know him personally and I know that he always does all the necessary checks.
Some older framestor releases are wrong and I just checked the Captain America hybrid is still available on BHD even though it's a VERY different grade and the RPU is not even in sync with the BL.
Same for their Black Widow release and others.

You can pm the list of hybrids you're not sure and I can have a look if i can find them.

Framestor Mando S02E08 Hybrid UHD out of sync too - prob all the (d+ or iT/D?) stuff

I just had a chance to check Mando and I can't see any sync issue. Can you provide a particular timestamp?

I'll get to this eventually - HVAC broke with part backordered so been out of my house for a couple weeks

Awesome thread, been following since quietvoid shared his method. Recently grabbed Ugoos AM6B Plus and have been updating DV files in my library. Afew questions would really save me some time:
-I just started using Reset_9999's tools afew days ago, all my DV profile 8 files have been created with quietvoids old bat files, is there
any reasons to redo these profile 8 again with Reset_9999's tools since they are maintained/updated?
-I've been using 4-2 workflow with the new tools to create fel and it works really well but I cant workout how to choose which streams i want to encode instead of the whole .m2ts file - choose which audio, no subs etc.
-Is there a updated database somewhere that listed what UHD are FEL? so I know which films I have to update.

Thanks!

No, my ''tools'' are just scripts that use the same quietvoid's dovi_tool.exe
Or maybe you meant yusesope's old bat file (original method)? If your file works, I see no reason to remux them again with the newer dovi_tool.exe

-I've been using 4-2 workflow with the new tools to create fel and it works really well but I cant workout how to choose which streams i want to encode instead of the whole .m2ts file - choose which audio, no subs etc.

dovi_scripts has a workflow to create ST-DL but it's not very useful/efficient because it has to mux to a hevc file with dovi_tool and then mux to MKV. It would be best/faster if you used MakeMKV(free in beta) or mkvtoolnix instead, because it can mux a BD to ST-DL straight to MKV and you can select any audio/subs.

Is there a updated database somewhere that listed what UHD are FEL? so I know which films I have to update.

idk but dovi_scripts Workflow 2-2 can quickly find if any input is FEL or MEL.
