"A Disturbance in the Force" releases on home video today, December 5, 2023!
Time

The documentary “A Disturbance in the Force: How the Star Wars Holiday Special Happened” released today on iTunes/Apple TV, Vudu, Prime, and Blu-ray. I had a chance to check it out in theaters a few months back at a festival, and had some good laughs!

The footage from the holiday special is also the highest quality of any other source I’ve ever seen. I highly suspect the filmmakers had a connection with someone who must have owned a higher quality source than the bootlegs we all know about, because it was surprisingly sharp and clean.

Anyway, I highly recommend the movie! (It’s still holding strong at 100% on RottenTomatoes too. Kinda insane).

Color matching and prediction: color correction tool v1.3 released!

Williarob compiled the tool for Mac with my support as a favour to some users, but there’s no long term support for Mac outside of what people like Williarob are willing to do. I don’t have a Mac, sadly, so I can’t be of help.

Is the code open source for other forum members to compile the latest version for Mac? I’d be interested in giving it a swing, if that’s something you’d be open to.

I sent a PM to 44rh1n but also posting here in case because I’m not sure how this forum works. Looking for a V3 download (if it can fit on a bluray disc, otherwise looking for V1). Thanks

If you’re looking to burn the film on to a Blu-ray, then V2 is actually your best bet. The encode is Blu-ray compliant, and perfectly fits onto two BD25 discs. So it will be spanned across two discs, just like the official release.

However, V3 would theoretically fit on a BD50 disc, though I haven’t tried it. (The encode should be Blu-ray compliant).

I think it would really be best to first have a completely EE sourced version.

The problem is that much of the EE source lacks luminance detail, which is detail that is preserved in the theatrical blu-ray. So despite other problems with the theatrical blu-ray, they are lesser problems than the lack of highlight detail in the EE blu-ray, IMO.

There’s probably better high-luminance detail in the new 4K blu-ray, though.

For what it’s worth, it’s possible use Rec. 2020 without any HDR. There is a benefit to it, albeit small. Some commercial discs do it, and (UHD) player compatibility is not an issue

Or the better route, in my opinion, would be to perform all restoration and grading work within Rec.2020 ST2084, but with an output transform set to Rec.709 Gamma 2.4. So effectively, it would be as if you were making the restoration in Rec.709; however, all of the hard restoration work would be preserved in a larger container, thus future-proofing the restoration.

In other words, you’d still view everything in Rec.709, and export everything in Rec.709, and release it in Rec.709. But internally, you can always disable the output transform and you’d have all the extra detail there. That way, in 5+ years from now when HDR grading becomes much simpler, none of the restoration work has to be redone. The only thing it will need is a new color grade. 🙂

And you can do all this with a standard SDR monitor.

44rh1n, I’ve successfully finished a 4K edit in Resolve using Dolby Vision and adding additional color correction. When I export the project, for example to an HEVC mp4, the final result looks beautiful. Note: the project settings are just as you specify (also the output is of course REC 709).

Here’s my question: when playing on a TV the HDR notification icon comes up signaling that this is HDR content. This this is just a flagging issue and this is fully an SDR export, correct?

Good question. How did you export it? Did you use instructions in step 8?

“8). Lastly, go to the delivery page and set whatever export settings you desire (again, I always recommend ProRes, but the settings you would pick depend on your needs). ***Then go to Advanced Settings, and change the Tone Mapping to Dolby Vision. Ensure the selected option under Dolby Vision is “100-nit, BT.709, BT.1886, Full.” Once you’ve got all your export settings enabled and you’ve selected the Dolby Vision tonemapping, you can add the export to your Render Queue and export it out.”

If you followed those instructions and still have an issue, then you may additionally need to go to “Advanced Settings” on the delivery page, and set the “Color Space Tag” to Rec.709 and the “Gamma Tag” to Gamma 2.4.

If you just export out on HEVC without using the 100-nit trim, then it will export the HDR version. However, it likely won’t be a great HDR grade if you didn’t do it with a proper HDR monitor.

Hey Harmy! For Despecialized 3.0, are you doing your restoration work in way that’s limited to Rec.709, or are you doing it in a wide color gamut / logrithmic color space? ​If you happen to be working in WCG/Log, then maybe we could work together to do an HDR/Dolby Vision release sometime in the future, if you’re interested. 🙂

**Important: Ensure “Mastering Display” is set to “1000-nit, BT.2020, D65, ST.2084, Full.” That is the correct option for most 4K Blu-rays.

ALSO: make sure the resolution and framerate are correct in the the Master Settings.

As for the 4000 vs 1000 nits, do I find the information in media info?
If not, how do I know which is which?

Could it be “Mastering display luminance” or “Maximum Content Light Level” (although in the second file this is higher than 4000)?

Thank you.

It’s the Maximum Content Light Level. So for the first one, it looks like it’s 636-nits, and for the second one it looks like it’s 4809. So I’d use the 1,000-nits setting for the first one and the 4000-nits setting for the second one.

7). Click Analyze All. (And leave Enable Tone Mapping Preview selected). Once it’s done, you’ll notice that the image no longer looks flat and ugly because you’re now seeing the SDR version created by the Dolby Vision analysis.

One extra step should be performed: if the video image itself includes the cropping black bars then these will need to be excluded from the output, otherwise the black in every scene will skew the analysis. This can be done by selecting Timeline > output blanking. Or otherwise manually cropping the top and bottom.

Yes! Thank you for mentioning this. I forgot to say this, but this is true. I’ll add it to my post above. I also forgot to mention the Mastering Display setting, so I’ve added that to step 2 as well. It’s important to set it to BT.2020 rather than P3, otherwise the colors won’t be quite right.

And based on your comment: “Once it’s done, you’ll notice that the image no longer looks flat and ugly because you’re now seeing the SDR version created by the Dolby Vision analysis.” it looks like I can further color grade after the analysis and before the rendering. Sweet!

Yes, you can do color adjustments after the Dolby Vision trim analysis, and your GUI screen will show those adjustments with the new SDR tonemapping applied on top.

krausfadr said:

EDIT: or perhaps a best practice for users of Resolve would be be to import the file container with HEVC HDR into Premiere, apply the Dolby vision, and export that to a DNxHD or DNxHR to be used as the new source to edit?

I personally recommend using the HDR version of the film as the source. This way, any fan restoration or fan edit you’ve made will be preserved in HDR, so your work is future-proofed and you can make an HDR version in the future after HDR grading monitors come down in price. Regardless of what method you choose to convert HDR to SDR (whether you use a Color Space Transform or the Dolby Vision analysis), you’ll still be able to export in SDR. You just also have the flexibility to make an HDR version in the future without having to redo the edit from scratch.

But if you bake out the SDR conversion and then use that as a new source, you’re actually limiting your ability to make color adjustments because the “new” SDR source has less dynamic range and a smaller color gamut than the original HDR source. And you also won’t have a future-proofed edit that can be used to create an HDR master in the future, if desired.

My head hurts, this is very confusing.
If there’s no metadata, then how can each scene be graded differently and why is it so difficult to make a conversion to SDR?

Metadata, or the lack thereof, has nothing to do with one’s ability to grade each shot of a film differently from the next.

The reason you’ll likely need to make adjustments on a shot-by-shot basis is because HDR (Rec.2020/ST.2084) has a completely different color space and gamma than SDR (Rec.709/Gamma 2.4). There’s no one-size-fits-all approach to a downconversion. They’re entirely different formats, with entirely different ranges of color and luminance. So you’re likely never going to find a one-click solution that’s perfect.

winoni71 said:
I’m not looking to make a restoration, but to have an “all-purpose” method to convert HDR to SDR while preserving (as much as possible, without grading scene by scene) the visual characteristics, I’m not looking for perfection.

If you’re looking for an easy solution that doesn’t involve performing shot-by-shot corrections, then you can use a Color Space Transform effect (as illustrated in this tutorial above), a LUT, or you can do the method that another user above suggested in Premiere. Just know that it’s a technical conversion, not a creative one. So while it’s an accurate HDR-To-SDR conversion, it might not always look how you want it to look.

If you’re not doing fan restorations / preservations, then might I ask why you’re interested in doing this in the first place? Wouldn’t it just make more sense to buy the 1080p SDR versions of the movies you want to watch? Or better, get a 4K Blu-ray player? (If you have the funds, that is.)

winoni71 said:
Knowing this, having at my disposal both Abode Premier PRO and Resolve Studio, what would you recommend to achieve what I’m looking for?

Thank you.

If you have Resolve Studio (the PAID version of Resolve), then I would recommend trying out the automatic Dolby Vision trim analysis. This will do an automatic per-shot conversion from HDR to SDR. So rather than a single one-size-fits-all approach, it will treat each shot individually.

1). Bring the film into the Media Pool (you’ll get much faster performance if you convert to ProRes first, as illustrated in the tutorial at the beginning of this thread. But if you have a fast computer then the original HEVC should work).

2). Go to your Project Settings and change the Color Management timeline color space to Rec.2100 ST.2084. Then check the “Enable Dolby Vision” checkbox.

**Important: Ensure “Mastering Display” is set to “1000-nit, BT.2020, D65, ST.2084, Full.” That is the correct option for most 4K Blu-rays. However, for some 4K Blu-rays that are mastered at 4000-nits, you’ll want to select the “4000-nit, BT.2020” option. ALSO: make sure the resolution and framerate are correct in the the Master Settings.

3). Add the film to a new timeline (make sure the timeline has the same framerate and resolution as your movie). The image should look flat and ugly on an SDR GUI display.

4). On the Edit page, select the movie in the timeline and then go to menu item “Timeline > Detect Scene Cuts.” This will take a while, but it will analyze the movie and make physical cuts to every cut in the film. Once it’s done, scrub through to make sure it didn’t add cuts where it shouldn’t have.

5). Navigate to the Color page and click on the Dolby Vision button on the bottom left region of the screen (the button won’t be there unless you enable Dolby Vision, as mentioned in step 2).

6). Ensure the Target Display Output is set to “100-nit, BT.709, BT.1886, Full.”

7). Click Analyze All. (And leave Enable Tone Mapping Preview selected). Once it’s done, you’ll notice that the image no longer looks flat and ugly because you’re now seeing the SDR version created by the Dolby Vision analysis.

**Important: If the movie is wider than 16x9 (includes black bars), then the black will need to be excluded from the output, otherwise the black in every scene will skew the analysis. This can be done by selecting Timeline > Output Blanking. There are some great presets for different aspect ratios. If none of those presets are correct for your film, you can create custom Output Blanking by navigating to the “Sizing” button in the middle-right of the GUI, changing the dropdown menu to “Output Sizing,” and then you can adjust the “Blanking” sliders. Or you can physically crop the top and bottom of the video by changing the timeline resolution and image scaling settings in the Project Settings.

8). Lastly, go to the delivery page and set whatever export settings you desire (again, I always recommend ProRes, but the settings you would pick depend on your needs). ***Then go to Advanced Settings, and change the Tone Mapping to Dolby Vision. Ensure the selected option under Dolby Vision is “100-nit, BT.709, BT.1886, Full.” Once you’ve got all your export settings enabled and you’ve selected the Dolby Vision tonemapping, you can add the export to your Render Queue and export it out.

Now you’ll have a beautiful SDR version of the film derived from brand new Dolby Vision metadata that you created yourself. 😃

Hope that helps.

P.S.: I don’t’ understand something though, isn’t the HDR metadata supposed to be there precisely to determine, frame by frame or scene by scene, what the picture is supposed to look like?

HDR10 does not have metadata. It’s just plain old HDR (Rec.2020 ST.2084), and nothing else.

Dolby Vision has metadata which contains information that trims down the the Rec.2020 ST.2084 (HDR) source to a Rec.709 Gamma 2.4 (SDR) output. But to my knowledge, that metadata from the disc is only readable on a TV.

You could import the Rec.2020 ST.2084 source into DaVinci Resolve and run it through Resolve’s Dolby Vision scan, and that will give you brand new SDR metadata which you could use to export an SDR video. However, it won’t have the nuances and custom adjustments that the colorist would have made for the original Dolby Vision pass.

I should also note, as a reminder, that HDR footage is similar to log camera footage – meaning, it has much more latitude to work with than SDR footage. So if you’re doing fan restorations, it’s better to NOT bake in an SDR conversion. It’s best to do color work within HDR, and then have your SDR conversion at the very end of the chain. That’s the workflow that this tutorial of mine hopefully illustrates.

44rh1n said:
WOW, you’re right! I just checked my iTunes copy, and it looks REALLY good! It’s still only HD for me (hopefully it upgrades to 4K for me eventually – iTunes usually does!), but it’s definitely the new master. It looks WAY better than the old green extended Blu-ray master!

So I’m curious about something. When you stream the new master from iTunes/Apple TV on an 1080p SDR monitor, what are you actually watching? I get that the 4K would just be downscaled to 1080p, but what about the HDR? Is there some kind of tone mapping being done, or does Apple already have a 1080p SDR version of the new master that automatically streams if they detect you’re using a non-HDR screen?

The simple answer is that the 1080p version is an SDR master that’s been derived from the HDR master. It’s not HDR, but it comes from the same source.

The more complex answer is that this was mastered in Dolby Vision. A lot of people don’t quite understand what Dolby Vision actually is, so let me explain: Dolby Vision is when you take an HDR (Rec.2020/ST.2084) graded master, and use Dolby’s trim analysis tools to perform a shot-for-shot tonemapping of the entire film. Every single shot is analyzed and remapped to fit inside of a Rec.709/Gamma 2.4/100-nit SDR container. After the analysis, Dolby has additional custom trim tools that allow the colorist to fine-tune the SDR version of the film. They can tweak the exposure, the saturation, and the balance/tint. This way, they can make SDR version look as good as possible. Then the same analysis/trim pass is repeated a number of times to accommodate the capabilities of different screens. For example, a brand new analysis and trim pass will be performed for 600-nit TVs, 400-nit TVs, etc. This is why Dolby Vision HDR looks so much better on consumer screens than generic HDR, because its tonemapping is done by the colorist himself rather than just using a TV’s automatic tonemapping. Every version of the film, tailored to your specific screen, was done by the colorist.

So when you’re watching the SDR version, you’re not just watching something that’s been automatically tonemapped. You’re watching the Dolby Vision SDR version that the colorist has actually created, using Dolby’s toolkit, and derived from that original HDR master. That’s what Dolby Vision is – a toolset that allows filmmakers to create an HDR master and then interpolate the color grade all the way down to SDR while preserving the original intent of the grade.

And yes, I would imagine that the new 1080p Blu-rays are going to be from that same Dolby Vision SDR trim. So they will likely look the same as the iTunes 1080p versions, but with a much higher bitrate.

Hope that makes sense.

Ah gotcha. Thank so much for all your help with this. I want my Hobbit fanedit to be at its best shape so this really helps. Sorry for all the questions, but I do have one last one. Would an HDR passthrough capture card suffice for viewing HDR or would I have to go for one of the Blackmagic devices? I don’t really use resolve that often and primarily use Premiere Pro CC for my basic color needs.

DeckLink and UltraStudio devices are for monitoring, not for capturing. So that’s an entirely different type of device. Also, generally people use the same Blackmagic devices for their reference displays when using Premiere anyway. Or AJA also makes some that work too.

Also, Premiere actually doesn’t even support HDR PQ at this time (the HDR format used on 4K Blu-ray). They have plans to incorporate it into future versions of Premiere, but it’s currently not supported. (You can still cut an HDR ProRes video inside of Premiere, but you won’t be able to monitor it in HDR or export it in HDR). Right now, Premiere only “kind of” supports HDR HLG, which is an entirely different format. And to be frank, their support is quite limited.

In order to color grade in HDR, you need to connect your HDR monitor as an external reference display inside of Resolve, not as a GUI display. This means you will need an HDR-supported DeckLink or UltraStudio device, plugged in through PCIe or Thunderbolt.

Also, if all you have access to is a consumer display, then the only ones that can “approximate” the appropriate range necessary for accurate HDR grading are OLEDs. Particularly the last two generations of LG OLEDs (C9 and CX). But even OLEDs require calibration and lots of setup. Dado Valentic has a really great guide for getting an OLED set up for HDR grading. https://youtu.be/T-oYDNbnVXQ

Also, grading in HDR is quite difficult, actually. If you’re not already familiar with grading in Resolve, then you’ll probably want to practice grading in SDR first.

This written guide of mine here on this forum is primarily intended for those who are interested in grading 4K HDR Blu-rays in an SDR environment. Grading in HDR really is quite a complicated beast at the moment for consumers. Most consumer hardware just isn’t really good enough yet.

…Every screencap I’ve seen of a shot that is 100% for sure not a VFX/composite shot definitely looks like a true 4K scan to me.

I think people are really underestimating how many composites and VFX shots are in these movies, and it’s already been stated that such shots are either 4K scans of 2K film-out negatives, or upscales of the 2K DI.

This. 100% this. There are so many VFX shots in these films, even shots that you wouldn’t ever think are VFX shots. But for shots that aren’t VFX, they definitely look like true 4K to me.

Also, I don’t know how anybody can complain about the Fellowship 4K release. It’s literally the best the film has ever looked on an official home video release. No other previous release even comes close! Sure, it’s not as close to the original color grading as my color restoration is, but the colors are a thousand times more natural than the previous extended Blu-ray release.

I haven’t had a chance to watch The Two Towers or Return of the King yet, though. And those revisionist screencaps concern me (although, I’ll wait to give my opinion on them until after I’ve seen how widespread those color changes really are). But honestly, I don’t see a reason to be complaining about these two films either, even if they did change the look. Why? Because these two films on regular HD Blu-ray already looked exactly like the original release! They look amazing on just regular HD Blu-ray. The only film that looked horrendous was Fellowship of the Ring, and now it’s (mostly) fixed.

We have all three films accessible to us, officially, in a way that looks pretty great. That’s what matters for both the consumer and for film preservation.

There are plenty of screens (capsaholic and BR forum) so atrocius i can’t believe someone had the courage to ok it.

There is someone with the idea of regrade from the TE bluray with the UHD as reference?

Sounds like you actually need to watch it in 4K HDR before landing on this opinion. Haha.

It’s not upscaled 2K, except for the VFX. Everything else is true 4K, scanned from the original negative. That’s also why it’s so clean. Sure, there’s some DNR, but nowhere near the amount of DNR in other film releases (cough cough James Cameron cough cough). And it doesn’t even come close to the amount of DNR on the original theatrical Blu-ray. Plus, LOTR always had digital sharpening. It’s part of how it has always looked. Sharpening is even talked about in the color grading BTS in the appendices from 2001.

The HDR looks really great on a true HDR display, like my LG OLED. I definitely recommend checking it out on a true HDR screen, preferably one with Dolby Vision support.

My only complaints so far are that the DNR could have been done a bit less, and the color grading could have been a bit more similar to the original DVD release (with the added HDR, of course). Some scenes are less warm from the original grading (Rivendell), while others are warmer than the original grading (flashbacks and Galdalf’s confrontation with Saruman). And skintone/midtones seem to be a bit more lifted overall in bright scenes than in the original grading. I also noticed some blues in Gandalf’s beard during his scene with Frodo at the beginning of the film, which looks like a stray qualifier of the sky. Kind of annoying. Reminds me of the stray power window that used to be in this exact same scene on the old green-tinted Blu-ray. But that’s me nitpicking! Without comparing it to the original grading, it’s quite good.

Granted, so far I’ve only looked at Fellowship. It’s a vast improvement from previous official HD releases. I still have to look at Two Towers and Return of the King, though.
