Let's say one makes a content with 1000nits master display and does 100nits trim for SDR. When the content gets playback on a 1000nits display, it will need to use 100nits trim? This does not make sense to me. Re-read my previous post and the following section in Dolby docs. You're focusing too muc...

Yes, it is primarily intended for that according to Dolby documentation and spec, as colourist should be monitoring on a 100-nit SDR display when making that trim, however, it seems that if it's the only L2 level trim present, it's still used to adjust tonemapping on at least some TV models and play...

Not only should we ask Dolby, but also ask LG, Sony, etc. Current behaviors of playback devices and display devices does not make sense to me. Well, unless you are new to this DV thing, we found out quite early that DV is a total mess filled with bugs. yeah. I have been following the thread. maybe ...

I didn't think your users would care to just play in HDR, if they don't care about bitrate. But to each his own. For Dolby website, try another browser or incognito window, I think I had similar issue and used Edge.

I use PLEX and some of my friends have very bad WiFi signal, when the 4K bitrate jumps to 40-50 Mbps they just buffer non stop. And second, I like to save place. I am happy with some quality downgrade when I can reduce video size. I can not afford hundred TBs of storage. This is precisely what &quo...

Yep, 6-2, got the same lavfilters settings, same error. This is not a fun error to deal with, as I had it before and took me a long time to resolve, lots of uninstalling/re-installing and troubleshooting. From what I recall, the key was to ensure I had 32-bit (x86) version of LAVFilters installed a...

With respect, I think you're overthinking this susanstone2022, as Dolby has very clear in explaining everything about DV, through extensive documentation, how-to videos, manuals, and partner software like DaVinci Resolve also includes a deep manual explaining what all the trim adjustments do and how...

Also, is there any chance that it is intentional for the positive lift L2 Trim to be ignored on TV-led devices if that is the case? Maybe Dolby determined that the TV should make its own decision in those cases...? I agree with RESET, it also doesn't make sense for Dolby's own Professional Tools to...

Excellent research and testing sir. I have a strong hunch Dolby doesn't care much more beyond signing contracts and getting the license payments from device makers, and cannot really be heavy-handed on forcing the manufacturers of consumer devices to perfectly implement their DV engine SDK or submit...

Amaury, That's another tool with its own dedicated thread over at doom9, so I recommend visit there: https://forum.doom9.org/showthread.php?t=183479 As for DoVi_Scripts, which is mostly discussed here, you should read all of the information first in the readme on github and try it first, then ask an...

Thank you for that info Reset_9999. I have an RTX 4070 TI so the GPU is definitely not an issue. I have posted the question in the Handbrake forums as to whether it is baking the FEL. I also referenced your scripts to them to see if they can add the functionality in the case that it is not already ...

Solution:
Change the edid to 800nits.
EDID: https://mega.nz/fm/YGlBmIQY

FYI, that MEGA link doesn't seem to work (I think it's for your own logged in account), but are you sharing a tool to change EDID on TVs or something? Just curious.

Thoughts on using a 2000nit MDL? It has a decent amount of scenes over 1000 nits. 4000 seems excessive though, so I'm between 1000 and 2000nit MDL for Resolve DV analysis. TIA :) You should update your script, I added more information that makes the decision easier. My initial recommendation was if...

Quick question; when generating CMv4.0 content (3-1), how does one determine what Mastering Display to use? I assuming higher isn't necessarily better? 2 options: 1- just use the static metadata from your source HDR10 2- check the brightness first with madvr. If 95% of the movie is under 1000nits, ...

Hi, I did some more testing with Flac audio. For some movies after converting trueHD/dts-hd to Flac (i think it applies to lpcm too) the resulting audio track is significantly lower volume. I'll check it out but I'm pretty sure LPCM is fine. EDIT: did some tests and the original THD/DTS, flac or lp...
