Thanks for the reply. How do I re-process, 4) MODE.P= / 2) MODE.2= right?

if your input is a bluray disc folder yes. 7-4-2 or 7-4-3
if it's a P7 mkv then use 7-4-4 or 7-4-5

7-4-1 is only for when you want to mux raw P5/P8 HEVC,AC3,EC3,SRT...

Hi all. Stupid question here, but is there a difference between a 1080p DV layer and 2160p DV layer? There is a release I am trying to hybridize and I have the 4K HDR, but only have access to the 1080p Profile 5 DV. Does anyone have any experience with something like that?

Hi all. Stupid question here, but is there a difference between a 1080p DV layer and 2160p DV layer? There is a release I am trying to hybridize and I have the 4K HDR, but only have access to the 1080p Profile 5 DV. Does anyone have any experience with something like that?

you only have to edit L5.

how do i know when it is a profile 7 file?

mediainfo ( text view / HDR format):
Dolby Vision, Version 1.0, dvhe.07.06, BL+EL+RPU

you only need to know that information when you are using Workflow.1 (manual). the other workflows auto-detect the input profile.

interesting, it fails when it tries to save the data into a graph, I have never seen that error and I didn't write that python script so I can't really help you here.( I assure you it's working on my PC)

did you install this version of color science?

Sorry, can you clarify what you mean? The phrasing of your answer seems to imply that it doesn't matter that it's 1080p, but I was hoping to hear more about it.

You can use my script (Mode.I / Workflow.1) and choose the automatic L5(when the script ask you)...

or

manually:
You convert the RPU to profile 8 as usual and you edit L5 to match the 4k video. E.G. if the 4k video has an active area of 1600px then L5 is:

Code: Select all

{
    "mode": 3,
    "active_area": {
        "crop": false,
        "presets": [
            {
                "id": 0,
                "left": 0,
                "right": 0,
                "top": 280,

            }
        ],
        "edits": {

        }
    }

Thank you, I'll check that out. I've made hybrids before, but not one where the quality on the DV source is different, so I was thrown off. Out of curiosity, what would be the difference if I simply had the 2160p DV layer? Would both layers produce the exact same thing, or is there slight quality loss with the 1080p layer?

if i have 2 hevc files in the media container. 1 for main and 2 for DV metada. so which profile is this?

i'm now always converting my mkv file to ts and then i use you' re program, if there is only one hevc file in the container. is this the correct way? (4-2-3)

The metadata are exactly the same (except the active area of course).
So no quality loss... I do it all the time by the way.

2 video tracks = profile 7 but for an MKV file (or original m2ts) mediainfo won't display the information.

You don't have to remux to TS. (4-2) will do the conversion regardless of if your input is dual or single track.
This was added recently, so make sure you use the latest version of the script.

yes, unless the language is one that I didn't implement.
By default, it will pick up the English audio/subs
