@RESET_9999 I measured HDR10 to get MaxCLL and MaxFALL metadata using madVR and excluding black bars to get a more accurate MaxFALL value, but when I open the measurement file with madMeasurementAnalyzer it gives me a different MaxFALL than the plot. Which on should I trust? https://images2.imgbox.c...

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 The problem was probably due to an outdated version of madvr.

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. madMeasureHDR.exe input.mkv https://s12.gifyu.com/images/StBup.png After trying I get this error: Drag and drop folder with HEVC video files or a single file and p...

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

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 ...

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 usin...

Hi everyone, some time ago I asked if anybody here knew how to change maxcll and maxfall values within the hevc stream itslef without the need to re-encode it. Well ,I've finally figured it out. Thus, a question comes to my mind: how important are these values in the actual playblack? I've seen man...

@RESET_9999 I recently came up with two questions about Dolby Vision work: 1. When having retail Dolby Vision what is better to use when generating HDR10+, OSCs or Davinci Resolve ones? (Or vice-versa) 2. Since UHD Blu-rays only have the CMv2.9 metadata block, is it better to generate a new Dolby Vi...

(1-1)(3-1) Script is now configured to keep the trims to match Resolve default (can be disabled at lines 48-52 if you prefer the old way) I'm a bit confused since in your updated video on how to generate Dolby Vision and HDR10+ via Davinci Resolve you explicitly mentioned that L2 trims must be remo...

I ordered the AM6B+. I think the only difference is the wifi 6 Trackings says it has now arrived in my country, I might get mine sooner than expected :) When you say the "old UGOOS AM6plus," do you mean this version? https://ugoos.com/ugoos-am6-plus-android-9-4-32-gb Not the 2021 Version?...

What are those L6 values? (The movie in question is Cars 3): Summary: Frames: 147321 Profile: 8 DM version: 1 (CM v2.9) Scene/shot count: 1630 RPU mastering display: 0.0020/1000 nits RPU content light level (L1): MaxCLL: 10000.00 nits, MaxFALL: 892.53 nits L6 metadata Mastering display: 0.0020/1000 ...

I see, thank you for the clarifications. Still, I don't understand how it is possible to change MDL or MaxCLL/FALL without re-encoding the video, but if it doesn't practically impact playback at all i think I'll get over this thought.

Hi everyone, since the topic of HDR metadata is well know in this forum I wanted to ask a question about it. While I was browsing some trackers I've found one release group which seems to be really aware of what they are doing with video and audio related stuff. In particular, they managed to change...
