@kazuma, simple answer is that true TV-led means basically passthrough essentially, and the TV does all the processing for Dolby Vision. Player-led or LLDV means the playback device does the processing and then sends the signal to the display. What's important to note is that TV-led is not always be...

Makes sense, I don't blame you either for leaving it in the past. Not to mention, a tool like that may have an unintended consequence of more "experts" and groups around the interwebz to modify retail values and spread misinformation about what they should or should not be.

Thanks for clarifying and confirming for Dune, RESET. I should also add that in some cases, the highest peak brightness found is actually in the studio logos or some 1-2 second blinding shot, and that is probably why studios don't always set maxCLL to match the brightest single frame in the entire m...

In my opinion, this group only "seems" or "acts" like they know it all, and they tend to just write very long and nerdy release notes and talk about using "industry" tools etc, but I've seen mistakes by them with audio and Dolby Vision metadata before (even plain conver...

I think the major selling point of DV previously or at the moment is L1 data compare to HDR10. Obviously that's always been the baseline marketing, the "dynamic" part of it. However, that's been there since the initial release and HDR10+ also has this, so what has changed, especially in c...

yes. i know it can do stuff other than diming pictures. my question is why a 1000nits tv need to use trim that target to 100nits display? the trim is created by referencing 100nits target. it does not make sense to use it on a 1000nits tv. I hate to do this, but please see Interpolation . This is l...

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...
