Injecting DV from Spiderman: Into the Spider-Verse WEB-DL into the UHD Blu Ray (which only includes HDR10)
Hey there!
So, I've been stopping through the thread and been reading various posts and screenshotting relevant ones, and I think I'm ready to begin this.
I believe I understand that converting DV Profile 5 into Profile 8.1 is not necessary to get an MP4 to have active DV detected for LG TVs (I have a C1), and it's moreso to avoid having no video/green video displaying when played on a display/player that does not support DV.
I also believe I understand that DV Profile 5 can be inferior to a Profile 7 DV if a Profile 7 DV of the same movie includes a FEL? Which would mean even if a Profile 7 FEL wasn't present, among a few other things, mapping a Profile 5 to a UHD Blu Ray video source might produce inaccuracies/grading problems (I've seen mention of using PQ to check for inaccuracies, not sure how to go about that or if it's even necessary)
Into the Spider-Verse was never released on Disc with Dolby Vision, that was reserved exclusively for streaming platforms. Streaming platforms offer UHD streams, so in theory, WEB-DLs would be UHD streams with UHD mapped Profile 5 Dolby Vision.
So, two questions, and then a closer.
- 1. If I had a copy of a raw, muxed, unmodified WEB-DL, and a raw, muxed UHD Blu Ray, would it be as simple as using a few tools to inject the Profile 5 into the UHD Blu Ray and simply sync the beginnings of the video file with the Blu Ray? I understand Blu Rays usually have a blank video stream with the data mapped, and Profile 5 for streaming services has a text file instead. I assume the programs take care of this discrepancy, no issues? And, I'm assuming because the Profile 5 is for streaming services and I noticed some people said that there are some oddities or inaccuracies when applied to Blu Ray, let me know if I'm mistaken, I assume the colors will be off.
But does that mean there is also a way I can make a modification or two to improve the oddities? Maybe I can view a stream off of a streaming service and take photos of the differences, maybe? Pardon my absolute naivete and inexperience, my problem is likely one you guys have heard a bunch before, but I really love the two Spider-Verse movies and want to see them in UHD Blu Ray sources + Dolby vision on my LG C1.
2. I am having difficulty finding WEB-DLs that actually include the DV. This is strange to me and I don't really understand it. I have only found a Hybrid made for the Italian audio, which appears to have converted the DV to 8.1. Would this source be usable? Can I verify nothing has been modified somehow, and just isolate/separate that out and apply that DV to the English UHD Blu Ray?
Final: All of that is assuming I can play the files IN Dolby Vision. I have a Windows PC with a RTX 3080 hooked up to my TV with an optical HDMI 2.1, but as I understand it Windows only supports HDR10. I have an LG C1, and a fast internal SSD>USB 3.1 enclosure to play high bitrate content off of from the USB port (assuming 2.0), and so that leaves my options to my LG C1s internal player, as far as I'm aware (other than buying something like an Nvidia Shield). This is okay, I don't mind using the internal player as I'm not a heavy movie digester, more of a visual quality enjoyer, lol (so the effort is worth it to me if only for a few movies).
So, assuming that a Profile 5 DV added to a UHD Blu Ray source is fine and dandy, based on what I'm seeing in the thread and elsewhere, I SHOULD be able to view Dolby Vision content on my C1s internal player simply by using ffmpeg to move a .mkv muxed UHD Blu Ray into a .mp4 container, provided it has DV Profile 5, 7, or 8.1 right? That would be all that's needed? If that's the case, would, in theory, that odd converted DV profile 8.1 DV source, when muxed into an MKV, work fine when wrapped in a .mp4 container? or do .mp4 containers require a certain DV version? I believe that the consensus is that when rewrapping as .mp4s, you have to sacrifice the UHD's Lossless Dolby audio (for reasons I don't understand. if there's a workaround or if somebody could explain to me why we can't have the best of both worlds I would really really appreciate it,) which might mean other considerations/sacrifices have to be made.
Sorry if anything I've written/asked is annoying or been repeated ad nauseum, I don't mind being told to go back to a specific page or post and re-read, I can try to follow a previously outlined process and ask any questions about what I'm stuck on. It would just really help if someone noticed if I was on the wrong track or made some false conclusions from what I've read so far, because I'm not sure if I'm grasping everything.
Thanks so much for the help!
