Guardians of the Galaxy Vol. 2 - UHD IMAX Edit

Author
Time
 (Edited)

So what a shame it was when Guardians of the Galaxy Vol 2 was released on UHD BD. It did not contain the larger aspect ratios on the disc. Luckily the 3D version did. And lucky for my wallet, the Best Buy Steelbook came with both the UHD and 3D versions.

Sources

  • IMAX promotional stills (For reference and rotoscoping)
  • IMAX promotional videos (For reference and rotoscoping)
  • UHD Blu-ray
  • 3D Blu-ray

Here’s the plan/process that I will do…

  • Prep each source to be edited (also will rip the main menu video track from the UHD since it is in full screen and it is montaged clips, use only the stereo audio mix (for editing purposes only) I will preserve the Atmos track, get the MKV files into editable codecs/containers, possibly split it out scene by scene, get the 3D version into full top and bottom 3D)
  • Edit (gonna take a long long time)
  • Deliver file (Will be stuck to 10-bit)
  • Rip the UHD disc folder structure, and remux to m2ts so the edit can be deployed to the UHD disc maintaining menus and features. (This one might take a bit, I’ll have to test it by buying the right sized discs, and then test it still, hopefully it works on a 100GB BDXL)

Here’s the task list…

  • Load the 3D source in as the base video track
  • Place markers in the 3D source where aspect ratio changes
  • Place markers for each camera cut
  • Crop the Top/Bottom 3D source to the side that best matches the 4K source. (I will also need to take note of the parallax cropping, which is where a movie that is post-converted to 3D needs to remove some of the image to eliminate depth distortion and helps the faux footage gain some depth (both sides will have this)) I will have to horizontally crop the footage to conform it to 1.90:1. If the difference isn’t too much between the two sides on the edges, then I might be able to make a full (uncropped) 1.90:1 frame out of some of the shots
  • Line up the 4K source into the new frame formed from the 3D source.
  • Hide the 3D source at 2.39:1 footage and recenter 4K source if need be
  • Color match the 3D source to the 4K source
  • Sharpen 3D source if need be to attempt to get it in line with the pixel density of the 4K source

What I’ll be using…

  • A crap load of hard drive space lol
  • Davinci Resolve 14 (Free, 15 is being unveiled at NAB this weekend!): This will be used to crop the clips, and initial alignment will be done here.
  • Premiere Pro: This will be used to color grade (since I don’t have the $300 Resolve license), I will export a Premiere Pro XML of my Resolve project
  • After effects: If I need to rotoscope or anything like that I’ll probably do it in AE.

Issues that will probably happen…

  • Can’t deliver in Dolby Vision obviously
  • The pixel density of the 3D source might cause inconsistency when lining up with the 4K source
  • It’s gonna take a long time to render each scene
  • The only HDR display I have is a 55inch TV
  • SDR to HDR conversion and color grading will be a long process as well, have to make sure it’s right, and will have to be done on my TV in order to see if it looks right.
  • Premiere Pro sucks
  • All my encoding from Resolve will have to either be DNxHDR 444 or Premiere Pro XML because the free version of Resolve only does H.264 for MP4 containers. My encoding from Premiere can be a Main 10 10-bit H.265 file.
  • I’m moving to a new city this month and starting a new job
  • I still need to finish my Despecialized Edition boxset
  • My wife will inevitably want me to do shit other than work on this.

This sounds like an extremely ambitious undertaking. I haven’t been keeping up with efforts to crack UHD encryption. That’s doable now?

It’s very doable. MakeMKV can take AACS 2.0 keys manually. I already have the UHD copy ripped. Authoring UHD discs at the consumer level on the other hand is still very tough.

Edit: Although you need a compatible UHD friendly drive.

I think the biggest challenge is round tripping UHD HDR content through and NLE and back out with metadata intact. I havent seen it done before. Personally id like to Regrain the T2 UHD release but cant find any info from someone whos done similar.

My biggest concern with the HDR metadata is getting into the NLE. Which is why I may just end up doing all of this in premier or hopefully the resolve 15 beta will allow me to import h.265 content. Cause as it stands I will have to convert the 4K source to h.264 to get it into Resolve and then I can only use that version of it to align.

As I go through this, I’m going to document my processes. So keep an eye on this thread for some of the info you’re looking for.

I don’t use Premiere, but AFAIK it should load lossless sources; so, it will be better to convert the UHD HEVC into lossless, instead h.264 (unless you want to use its lossless version, of course!)

That’s a gigantic project; hope you will success; curious to follow your work in progress, because I think we all, sooner or later, will be “forced” to make our project in UHD (and I can’t think about 8K! 😄 )

I’m going to play around with some files tonight and see truly what Resolve and Premiere will accept. But I also need to make sure that the HDR metadata isn’t tossed in a conversion. Adobe Media Encoder hates raw H.265 wrapped in a MP4 or MKV container. Same with Resolve. I want to avoid Handbrake if I can because it’s a hog. I like ShanaEncoder but there isn’t much flexibility over the options, plus it tosses out some of the metadata as well.

My goal is to get this all back into an H.265 MKV with at least 10-bit HDR

So I did play around a bit last night with SDR to HDR color grading. I don’t have my pc plugged into my tv but I deployed my tenders to my iPhone X. In order to properly view the footage, my iPhone has to be at max brightness, and it’s still a little dark. Which is weird cause I can watch Dolby Vision movies on iTunes and be at a third brightness for the colors to pop a little.

This sucks cause I don’t want to blow out the highlights.

I did find someone who has an HDR grading lut for rec709 monitors however he took the tools he made offline as he makes adjustments to them. I also tried other software to view the hdr footage on my PC and they are all just too dark, even with my UHD rips.

I’m going to the new city that I’m moving to tonight to look for apartments. Won’t be back till tomorrow evening. So I’ll have to work on this on Sunday. I might just take my pc out into my living room and plug it into the tv to really get my color grading workflow down.

I have messed around with color grading from rec709 to rec2020. And I have it down now. Good quality.

Tip: On an HDR display don’t turn on HDR in Windows. The display will work better in NLE’s without it and you’ll also have the proper brightness. If you turn HDR on everything will be dim no matter what and the the brightness will be awful not to mention if connecting to a tv it will lag a little more.

I plan on setting my tv as my viewing monitor after I get moved into my new place. The home theater and my desk will be downstairs at my new place so it will be really nice for editing.

Hi railerswim,
Are you on a Mac perchance? The reason I ask is that Apple’s Final Cut Pro X just had an update that supports wide color gamut and HDR editing all the way through, including delivery in HLG or Dolby Vision. If you’re interested, or know someone who has a Mac, there’s some info at: https://support.apple.com/en-us/HT208229 It’s funny because I just watched a video on Youtube this afternoon that covered all of this. Hope that helps! 😃

Jedit: Ah! I see that you figured it out while I was typing. 😛

I’m on Windows. Btw some more info on Davinci Resolve 15 just got leaked. Blackmagic Fusion VFX will be embedded in Resolve now.

I could run a Hackintosh install but it just makes stuff unstable. Resolve is much better for color grading which is a major part of this project and Resolve is the number one color grading tool.

So I have been playing around in Davinci Resolve 15 beta. It’s freaking awesome. However, I’m on the free version. The studio (pro) version costs $299. As I move into the project more and more, I may purchase it. It will allow for rendering Dolby Vision data, although I’m not sure if I’ll need a Dolby Vision license of some sort to deliver the file. Worst case scenario, I can do HDR10+ with that version.

But I’m packing up to move right now. I move a week from Saturday. And I’ll have to get all of my ID’s and Documents changed over for the new county I’m in. Plus my new job isn’t 9 to 5, and I’ll have to go back to my hometown every weekend for a couple weeks for other stuff.

HOPEFULLY, my first few weeks of my new job aren’t too demanding and I will be able to work on this.

Sorry I’ve been off for a while. It’s difficult getting it to work since the post conversion to 3d distorts objects.

Also my new job is in full swing. I don’t even have the first scene done yet. It’s so long of a process lol. If a broadcast version comes out soon I may be able to speed this up.

Why not keep the whole frame for the 3D shots. No need to center cut with the UHD.
