Hybrid simply means multiple sources were used, sometimes it has nothing to do with the video/DV layer, but rather audio tracks taken from other discs for example. Release notes help make it more clear.

Anyone else notice that the RPU for apocalypse now goes way out of sync for the redux version. All other versions seem to be fine. I’ve watched this on the disc and didn’t notice any sync issues, has anyone tried this? Maybe an issue with makemkv?

Yep, I just tried with makemkv and the RPU seems to go out of sync at frame 32982.
I did not watch it but the scene cuts seem fine if I demux with tsmuxer and use dovi_tool.exe to make the ST-DL hevc.

makemkv scene cuts (OOS): https://justpaste.it/a8i23
tsmuxer demux scene cuts: https://justpaste.it/cmmbn

and the rpu is missing frames and is 5kb smaller with makemkv: https://slow.pics/c/AbM7fpJV

Yep. Ended up figuring that out too last night. Demuxed each segment with tsmuxer, combined BL and EL with your tool and then appended them in mkvtoolnix. Really odd this happened though, I’ve never encountered an error with RPUs using makemkv and I’ve ripped so many discs.

Does MakeMKV throw an error when this happens? Or did you only notice during playback?

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 still haven't gotten to go back and check this and all the latest RPU added UHD titles I processed when noticing this yet (I also encode the base layer to 45mbps if over, so who knows if that threw it off too - but for 99% up to now it hasn't, so) - but if I recall it was near the end where Luke comes in at the elevator scene and kills the death troopers for that title.

I also noticed one slight misalignment in Baby Driver at the very start when he's waiting for the first group to get out of the bank, for a split second there's a RPU misalignment on a closeup of him looking at them from in the car, but no where else in the movie that I saw.

if you have access to my RPU google drive collection, I already did all the work for all the movies.
Hi RESET_9999 - first off, if you are the one who maintains that Google Doc about which movies can and cannot have the Web DV metadata injected into them (along with everything else on that doc), THANK YOU! It's been priceless in my quest to understand all this stuff and make sure my collection has the best version available for the movies I care about.

Second - is there a way I can get access to this RPU collection? Does it come with a list of which versions/rips of the movie the RPU is compatible with, along with a brief walkthrough of how to combine the RPU with the base HDR10 file? Is the resulting file generally a Profile 8.1 mkv file?

Thanks again! Funny seeing you here when you were the one that probably started me down this path of understanding in the DV thread on the Infuse forums.

Sorry, the link is hidden and instructions to access it are in the Resolve HDR10 to DV tutorial. It's just a bunch (over 600) of Generated XML/RPU and original synced P5 RPU. You can use Dovi_scripts to verify scene cuts with your bluray remux in workflow 2-1 but 95% of the collection is probably USA discs.

Gotcha - I watched that video and saw in the description how to get access - I'm going on a trip soon but I might take you up on that when I get back.

In more general terms - my Plex library has a lot of Dolby Vision encodes (ie - not Remuxes) in it that are labeled as UHD Blu Ray rips and DoVi profile 8. But then when I look at the specs for the Blu Ray release, it's a FEL release.

I'm not sure if there's any way to know this, but in general, are these encoder groups just converting the base layer to profile 8 and throwing away the enhancement layer data? Or are they smart enough to actually be baking the FEL into the BL?

EDIT: And a corollary to that last question - if i'm looking at screenshot comparisons from your Google Doc, and if I don't see ANY difference between the stills in a BD FEL VS BL comparison, does that mean it's likely ok if an encoder ditched the FEL and just went with the BL? In this example, I'm looking at Pulp Fiction, and I don't see a single difference between the two stills.

It looks like Pulp Fiction's FEL is only 3847 kbps. Does the bitrate of the FEL generally correlate to how "important" it is? IE - this relatively low bitrate FEL isn't doing much and can probably safely be thrown out, whereas the much higher 13877 kbps bitrate of The Truman Show means it's far more important to make sure the FEL is properly dealt with and not thrown away. Is that correct?

I highly doubt that.

I've listed the groups that bake FEL and those that don't. I did not check all of them but most didn't encode FEL to P8 correctly.

yes

the EL bitrate doesn't mean much. I've seen 18mb/s EL that adds nothing to the BL.

You can just grab the web-dl for mando and do the hybrid yourself for the last ep of s2. I also noticed it was out of sync back when I put on on my server, so I did this. Sync is fine now, checked.

Didn’t even get far enough for playback. I check all my RPUs because I’ve been burned before (early framestore hybrids, yuck). But no, makemkv didn’t throw an error, so that’s not great.

I’ve got a question for you RESET_9999 because I value your opinion a lot, I think we all do here.

Certain newer releases have lots of static metadata. For instance, Furiosa, Creed III, Kingdom of the Planet of the Apes. Should I go ahead and generate metadata for these films or should we respect what the colorist has done so far?

Just to test, I’ve generated metadata for all 3 of these films and the mapping is now very dynamic, but is that potentially defeating the original intent by the colorist?

Thanks.

As long as they did the trims correctly it doesnt really matter if L1 is static and L1 values under your TV target are ignored anyway.
For example in Kingdom of the Planet of the Apes, they did a crazy amount of work on the trim pass.

this is all done manually by the colorist and no generated L1 will ever be able to match this:
