Dolby Vision now possible through MP4 Mux.

[johnjon94]

DoVi_Scripts_1.8.9.1.beta
(3-1) can now generate DV with the Dolby cmv4.0 algo without the need for Davinci Resolve. It can also work without an nvidia GPU.
It can generate frame-by-frame long-play or shot-by-shot metadata. I haven't compared the scene cut detection algo I'm using with the one in Resolve yet.

needed exe (metafier and cm_analyze) can be found here: https://customer.dolby.com/content-crea ... tools-v530

Some explanatory manual of how to perform the process with DaVinci

there's an SDR to HDR template in my script tutorial folder that will convert gamma 2.4 to PQ.
Then you have to play with the HDR settings in resolve.

Hello! Please tell me with what software I can change the fps of the Atmos track?

DEE but you should change the video fps instead.
https://professional.dolby.com/product/ ... ng-engine/

Hi RESET_9999! I know how, my question is exactly - Will the HDR10+ metadata work correctly IF! the two videos are different frame sizes? Is there any parameter similar to Level 5 in HDR10+ metadata as in Dolby Vision?

if the frame order is the same, I guess so. I don't know much about hdr10plus

There would be some possibility to add in your tool in the 6-9 the possibility to add or modify HDR metadata such as Luminance monitor mastering, Light level maximum content and in maximum medium frame .. thanks is just to know if you could

6-9 already takes the metadata from the source rpu.

Awesome update. Looking forward to testing it out.

How is the processing speed compared to resolve?

[RESET_9999]

How is the processing speed compared to resolve?

the frame by frame analysis is faster because you don't have to do the scene cut detection.
the shot by shot is slower because the current scene detects algo can't use the gpu. It also detects much fewer shots than in resolve & original.
https://www.scenedetect.com/
if anyone knows a good scene-cut detector tool? please let me know.

Here's a full comparison between resolve and the cm_analyzer:

L1: https://slow.pics/c/frlloVtT
L2: https://slow.pics/c/DVh8ttfe
L3: https://slow.pics/c/iu6FypAK

As you can see Resolve + downscaling is still what produces the closest metadata to the original. The shot by shot analyze also boost the L1 number just like in resolve when you don't downscale.
This new workflow might still be useful to people that don't own Resolve.

Thanks for the new tools @RESET_1999. Can't wait to try them out.
But first I want to check that I am correctly diagnosing when files have brightness expanded via FEL layer.

First we have Mission Impossible: Fallout: https://slow.pics/GmtF2CDS/
This FEL file shows a maximum display luminance of 1000 nits in mediainfo, however here it is 4000. We can see the file actually reaches 4000 nits as well in the MaxCLL. So this would be an example of brightness expanded via FEL layer, correct?

Next is Carrie (1976): https://slow.pics/ynAwxGW9/
This is also FEL. Both mediainfo and this graph with RPU/L6 show mastering display luminance as 1000 nits. So this would be an example of a title where the brightness is NOT expanded via FEL?

Note that Mission Impossible: Fallout is not included on your list. But also, for sanity's sake, it would be great to keep track of which titles DON'T have expanded brightness via FEL layer, along with those that do.

Thank you so much for your help!

Hi all!

Completely noob question but I've spent a couple weeks looking for the answer and I haven't found one. I have a LG E8 55" connected to a Vizio M512A-H6 soundbar via ARC.

According to the DV Google Doc spreadsheet, my TV's internal player should be able to play the included DV sample files (dual-track and single-track dual-layer profile 7 DV) just fine but it's not. The single-track sample doesn't play ("file can't be recognized" error), and the dual-track sample trips the Dolby Vision tag but the video cycles through a literal rainbow of colors throughout playing it, and the player says the video doesn't support audio.

Played on Plex, the story is slightly different. The single-track sample video does play, but it only trips the HDR tag. The dual-track sample trips the Dolby Vision tag but does the same "rainbow" cycle.

Ultimately, my goal is to be able to convert profile 7 BL+EL+RPU UHD rips to profile 8 .MP4s to play on my Plex, but the only files that seem to play successfully on my Plex (run from a macOS server, played on my LG TV's WebOS app) in Dolby Vision are profile 5 WEB-DL rips. Atmos seems to only successfully play when it's EAC3+JOC DD+. The profile 8 .MP4s I mux together from a BL+EL+RPU DV track and TrueHD 7.1 Atmos do play, but they default to HDR10 and Dolby Digital audio. I'm aware that my TV won't play TrueHD period, so it's not as big a concern.

So my actual question is, is there something wrong with my TV? I've been using the DoVi Scripts v1.8.9 to convert the .MKV profile 7 UHD rips I have to profile 8 .MP4s, but I haven't found success yet. I'm probably just missing something obvious. At least I hope.

[Trees]

Ignoring the bit rate, what HDR offers the best quality? Does P5 DV offer features P7 DV doesn't have (besides a slightly more efficient colour space)? Does P8 (HDR10/HDR10+ and DV) offer any features P5 / P7 doesn't have?

P7 FEL > P5 > P7 MEL = P8 > HDR10plus > HDR10 > SDR

P7 fel is 12bit so it is better than the P5 10bit colorspace.
P8 has the same dynamic metadata but only 10bit colors.

So I was in the right track in the first place. Thank you very much!

Quick question; are you familiar with FFMPEG? I'm trying to convert a P5 MKV into a P5 MP4. Do you know the command for this? I've tried all sorts of options but the DV data seems to get erased, my TV does not trigger DV.

I would use your workflow tool, but I use Linux and it does not properly work in Wine nor in a virtual machine, for some reason...

Bonus question: I'm able convert P5 MKVs to P5 M2TS, which play fine on my TV, but subtitles aren't displayed. The subtitles section of the TVs internal video player detects them, but doesn't display them, is there any specific reason for this?

MDL is usually a good indication but you cant only rely on it... The only way to be sure is by plotting DV and HDR10 or exporting screenshots with the dovi baker



EDIT: had a look and FEL does expand the brightness like all the other MI

because they are PGS, you need external SRT.

Here's my experience with the C8 ARC + PLEX...

1- For dual track DV: The container must be MP4 and muxed with the old mp4muxer/mp4box. (7-2) in the script.

2- For single track P7 DV: Some file will work some others will stutter or produce a black screen.

3- For the audio: It can be DTS AC3 AAC EC3. TrueHD won't work and will force HDR10 or fails to play

4- For the subtitles:
TS/M2TS: only external SRT will work. Any PGS subtitles will fail to play in DV.
MP4: internal or external SRT is fine.

Thanks for the help! A few follow-up questions:

The 7-2 script flow says it's for single-track output for older LG TVs. I tried it anyway and selected to convert the RPU to profile 8 and convert the TrueHD audio to DD+. The video track conversion seemed to have gone fine but I got multiple errors when trying to convert the audio:

Is there some file I need in the tools folder or some program I need to update?

Finally, going back to my experience with the sample videos, the "RPU FEL TEST DT DL P7" sample video did trip the Dolby Vision tag but the colors were strobing the entire time. Is there a reason for that? Even though it's giving that particular bug, the DV tag looks like progress to me. Again, thanks for all your help.

Yes, you're missing the PLEX files/folder used for the 7.1 EC3 encoding...
FYI, you'll get better DV playback stability if you use the TS container (Workflow 4-2). Much faster remuxing/processing as well.

It's a homemade rpu test file and the strobing is normal.

@RESET_1999 While converting mkv to ProRes, should I use "propres staxrip template.srip" or "ProRes 422 HQ QSCALE=1.srip"?

[UNSCTrafalgar]

Yes, you're missing the PLEX files/folder used for the 7.1 EC3 encoding...

Gotcha. I think I'm on the way to getting it right but I'm not all the way there yet.

I installed Plex Media Server and copied the "Plex Media Server" folder into "\DoVi_Scripts_TOOLS\tools". I also copied the PlexTrasncoder.exe file into the same "tools" folder and also EasyAudioEncoder.exe into every folder I can think of. Despite this, I haven't been able to get this error to stop popping up:

What content do I need to be putting where? I'm at a loss here.

all the tools are available on the dovi script GD link. download , extract and run the bat file.

@RESET_1999 While converting mkv to ProRes, should I use "propres staxrip template.srip" or "ProRes 422 HQ QSCALE=1.srip"?

"propres staxrip template.srip" has qscale to 4 if I remember correctly. Both are fine but qscale=4 will be faster and take less HDD space
