PREREQUISITES:

[Install/Download using the below instruction]

1. StaxRip (read the author's wiki) and paste the Templates folder (Link to download the Templates) contents into it StaxRip>Settings>Templates and run the StaxRip app and select the Settings folder as the option (one-time setup).
2. Run these using PowerShell/Command Prompt: install_apps.bat & install_python_libraries.bat
3. Dovi.Scripts, carefully read the instructions given by the author to set up. Also refer to the youtube playlist for your reference

SOLUTION:

[Blu-ray Ripping & Reading Metadata]

1. Rip the Blu-ray using MakeMKV (already installed from install_apps.bat script), and verify the now created MKV file (hereinafter referred to as the "OG" file) contains the Dolby Vision or not by using the latest version of MediaInfo (already installed from the install_apps.bat script). Open the “OG” file in here and view it in either HTML or Text form, and look for the "HDR" info stating something like this HDR format : Dolby Vision, Version 1.0, dvhe.07.06, BL+EL+RPU, Blu-ray compatible / SMPTE ST 2086, HDR10 compatible

[Dovi.Scripts Encoding]

1. Once verified that Dolby Vision metadata exists, run the Dovi_Scripts_MKV.bat file and select MODE.I= INJECT / EDIT / EXTRACT / INFO / VALIDATE and follow the instructions given there, add the “OG” file here, and read the Dolby Vision metadata values Top, Bottom, Left and Right
2. It should be like this
3. And not like this
4. If the values are wrong as shown above, follow the below steps. (this will take time, so be patient.)
5. Run DoVi.Scripts\tools\AvsPmod\AvsPmod.exe this application and drag and drop the “OG” file. Select Video>Crop in this window and enter the crop values. Refer to this youtube video for better understanding.
6. If you haven't closed the Dovi_Scripts_MKV.bat file, then select CHOICES: (default=X Exit) Exit=X L5=5 L6=6 L9=9 Resync=R or D SceneCut_Edit=F Source_PQ=Q PLOT=P Extract=E Check_Sync=S Metafier=M Transfer_Levels=T P7_to_P8=7 Remover=V, choose option '5'
7. Input the relevant value; recommended is using manual option 'm'
8. Input the required Top, Bottom, Left and Right values and then proceed.
9. Once if everything is correct, you should now have a fresh new file of “OG” as “OG_DV”

[StaxRip Encoding]

1. Start the StaxRip app, and then select File>Templates>Select the relevant template for Source select the “OG”/“OG_DV” file, whichever is relevant.
2. Once StaxRip has successfully imported the file, verify details about the same are getting shown properly.
3. If you wish to make edits to the metadata of a file, like the audio name tags and subtitle tags, etc. Click, Container Options.
4. Once all is in place, click Add Job and Start.
5. Once StaxRip has finished processing, you should now have “OG_new” / “OG_DV_new”.

[Dovi.Scripts Verification & Comparisons] (Optional)

1. Once StaxRip has created the file, run theDovi_Scripts_MKV.bat file and select MODE.I= INJECT / EDIT / EXTRACT / INFO / VALIDATE, and follow the instructions given there, add the “OG_new”/“OG_DV_new” file here and read the Dolby Vision metadata values Top, Bottom, Left and Right, and verify if all is as per your liking.
2. Again, run theDovi_Scripts_MKV.bat file and select MODE.S= Screenshots & Player> Workflow.2= MULTIPLE INPUTS: PQ screenshots DVP5/HDR10 or SDR vs SDR (Libplacebo), and make the comparisons.
3. You may now delete the previous files created and now only preserve the “OG_new”/“OG_DV_new”, or if your storage spares you, you may keep the “OG”/“OG_DV” & “OG_new”/“OG_DV_new” files.
