Dolby Vision now possible through MP4 Mux.
Re: Dolby Vision now possible through MP4 Mux.
Good evening.
I apologize using the link Read Me https://github.com/quietvoid/hdr10plus_tool
I can download "hdr10plus_tool.exe" and not "hdr10plus_parser.exe"
Should I rename the file?
Thank you

Re: Dolby Vision now possible through MP4 Mux.
First, most of the movies are done in CMV4.0 but exported in CMV2.9.jayper wrote: ↑Tue Mar 07, 2023 9:54 pmThanks so much! Apologies, but I am not yet well-read on the CMV4.0 vs CMV2.9 discussion. Is there a reason one would prefer one versus the other? I'm guessing it is more future-proof, but at this time most hardware doesn't support it? Is there a downside to keeping it?
CMV4.0 is backward compatible with cmv2.9. The trim passes (100-600-1000nits) are done in the level 8 for cmv4.0 and level 2 for cmv2.9.
When a device and the rpu are CMV4.0, the L2 trims are ignored because it will use the L8 trims which is the proper behavior.
Now the problem is that most of the CMv4.0 movies only have a 100nits L8 trim pass which is obviously not used in DV playback but they do have proper L2 trims that are ignored on cmv4.0 devices (shield/firestick/appletv/internal tv ). So you get inferior quality on those devices unless you remove the CMV4.0 block. The test files (made with original metadata from the movie Puss in boots) show exactly the problem and I bet this is the reason why we do not see a lot of CMV4.0 movies because the colorist has to do the trim passes two times (L8 + L2).
In my script, you can use 2-6 to export the trims to a text file and verify the raw data. So if you use a CMV4.0 devices, you might want to inspect your movies for cmv4.0 metadata (mostly amazon DV and movie anywhere web-dl ) .
Sorry for my English.

Re: Dolby Vision now possible through MP4 Mux.
yeah, in the next script version I'll keep the original name "hdr10plus_tool.exe" but for the current 1.7.6, you have to rename it "hdr10plus_parser.exe" or you can change the tool path name at line 93dom61 wrote: ↑Tue Mar 07, 2023 10:25 pmGood evening.

I went ahead in the procedure and when I am processing the file "DV.xml", it is prompted to enter a value of enter a value of CANVAS_WIDTH
How to do this?
Thank you very much

Re: Dolby Vision now possible through MP4 Mux.
mediainfo is used to read and set the input resolution. So your path to mediainfo might not be right??

That's not really how the workflow works.RESET_9999 wrote: ↑Tue Mar 07, 2023 10:39 pmI bet this is the reason why we do not see a lot of CMV4.0 movies because the colorist has to do the trim passes two times (L8 + L2).
The grading is done in CM v4.0 and the L2 metadata is generated automatically by software.
So the trim passes are still done only once.
Anyways, there has to be more experimenting on how CM v4.0 and L8 behave.
I don't agree that it should be removed.

Re: Dolby Vision now possible through MP4 Mux.
yes it is how it works... Each trims are edited manually after the analysis to make sure the desired look is preserved.That's not really how the workflow works.
Dolby vision is not just an algorithm.
Just take the Spears and Munsill clip and generate DV in resolve, the automatic trims are a LOT darker than the original as shown here https://drive.google.com/file/d/1_PkGF9 ... share_link
As I told you in PM, take the spears and munsil, generate cmv4.0 metadata and compare on cmv2.9 and 4.0 devices. I'm sure you will agree.Anyways, there has to be more experimenting on how CM v4.0 and L8 behave.

Re: Dolby Vision now possible through MP4 Mux.
I'm only clarifying your statement that the trim passes are done two times (L8 + L2), because it's not true.RESET_9999 wrote: ↑Wed Mar 08, 2023 3:06 amyes it is how it works... Each trims are edited manually after the analysis to make sure the desired look is preserved.
Dolby vision is not just an algorithm.
If you even did a little research, you would've found that L2 is always autogenerated.
So the trim passes are what creates the L8, not the L2. At least in a CM v4.0 workflow.
For CM v2.9, of course the trims are done once and they result in the L2.
That's not at all the same situation. It would only be comparing different algorithms.RESET_9999 wrote: ↑Wed Mar 08, 2023 3:06 amAs I told you in PM, take the spears and munsil, generate cmv4.0 metadata and compare on cmv2.9 and 4.0 devices. I'm sure you will agree.

Re: Dolby Vision now possible through MP4 Mux.
LOL I know very well that the dv analysis generates L2/L8 automatically, I literally asked you by pm how to overwrite them in my script because they have a too strong effect....
My point is that the trims are edited manually after the analysis. They are NOT just the result of an algorithm.
The metadata in L2 and L8 works quite differently as you know, so i disagree with you here.I'm only clarifying your statement that the trim passes are done two times (L8 + L2), because it's not true.
If they do L2 and L8 trims they must go through each of them but then we learned that the studios can be very lazy so who knows how much work they really put in the trims.
huh? please do some tests and then come at me againThat's not at all the same situation. It would only be comparing different algorithms.

After processing a movie with DaVinci, I performed the export of Dolby Vision metadata (DV.xml), following the tutorial on Youtube as reference.
I ask if it is possible to inject only Dolby Vision metadata (DV.xml)
to get Mediainfo similar to this.
Thank you very much

Re: Dolby Vision now possible through MP4 Mux.
No, you can only create single layer files. In order to create a P7 dual-layer file, you must have/create an enhancement layer (EL) which is currently not possible.dom61 wrote: ↑Wed Mar 08, 2023 6:54 amAfter processing a movie with DaVinci, I performed the export of Dolby Vision metadata (DV.xml), following the tutorial on Youtube as reference.

It might be possible to make a blank EL in the future though but i believe the BL has to be encoded a certain way also.

I finally managed to import DV metadata, ask for confirmation if the procedure is correct.RESET_9999 wrote: ↑Wed Mar 08, 2023 11:59 amNo, you can only create single layer files. In order to create a P7 dual-layer file, you must have/create an enhancement layer (EL) which is currently not possible.

I performed the procedure only for Dolby Vision, launched DoVi_Scripts 1>1 Drag & Drop MKV file and DV.xml file
![Image](https://i.postimg.cc/HLkqQwWJ/Screenshot-004.png)
And only the ".hevc" file is generated. , then I enter the file in MKVToolNix to create the mkv file which has these characteristics.
The "RPU.bin" file is not generated as in the videotutorial

Re: Dolby Vision now possible through MP4 Mux.
yes by default no rpu is exported.. you must edit line 35 set keep_rpu=NO
Also, you must have turned off the muxing(line 21) because the script is supposed to mux to MKV.

Re: Dolby Vision now possible through MP4 Mux.
Thanks man, that did the trick! I don't know how I didn't download that version as I thought I just went on google a couple of days ago and downloaded the lastest one. But it worked and I got my x700 in the mail today and tested it out. It played in hdr10 at first but I noticed that DV was turned off in the settings, so after I turned it on it worked like a charm! Its funny how even though this x700 feels like a cheap piece of plastic it plays back DV so effortlessly.RESET_9999 wrote: ↑Tue Mar 07, 2023 2:22 amNo, you'll get "fake" DV if you do that. You must remux to TS/M2TS or BDMV with the nightly tsmuxer.sultanmehmet wrote: ↑Tue Mar 07, 2023 1:42 amCan somebody confirm if I can just copy the 'raw' m2ts file to my HDD?
It sounds like you're using the very old tsmuxer. I use this version (had issues with the latest ones)...
