Dolby Vision now possible through MP4 Mux.

im assuming once the RPU is synced once and i extract it untouched it should then sync up with my encode flawlessly since the original remux i took it from was synced....

That's right, no need to resync RPU.

okay i only ask because on a couple of my encodes (all with the exact same encode settings) i have been getting an issue where my video file will play a little crazy (video speeds up really fast)...it only happens when the DV is activated not on HDR, so i was thinking it may be a DV sync issue...here is a video an example of it speeding up...

it will do this even if the video is the only file in the MKV container so it isn't an audio issue..
im playing my files back on a chromecast with google tv...

[staknhalo]

chromecast with google tv...

ding ding ding

that's my guess

wanted to stay with the chromecast for fel as main player but had to go back to the shield because too many qol issues with it compared to shield including dolby vision playback, for me it would skip continuously in dv mode with plex but only that device not the hisense tv or shield i have on the same files with plex, no matter if in mp4 or mkv like you

edit: i have a tivo stream 4k that can do dolby vision fel too i confirmed myself here a while ago but the device was too underpowered to even consider as my main player (has to run philips hue light entertainment zone locally on device while game streaming or watching video, which tivo couldn't do both) so i haven't tested it in a while

Don't know if you still have the sourcefiles, but maybe it's worth to check whether a new extract & inject RPU and remux with latest versions of dovitool and mkvtoolnix solves it.

Hello colleagues, first of all I apologize for my way of expressing myself because I am Spanish, I do not speak English and I use a translator.
I've been using DoVi_Scripts 1.2.1 for a couple of months, making Bluray Disc dvhe08 profiles and dvhe05 profiles without problems, with this scpript it's very easy.
But my problem is that I don't know how to extract the dolvi vision layer from a dvhe08 profile. I open the script, hit option "6"(Reader/Extractor/Remover/Editor/Audio_Converter and more), hit option "1"(Read/extract RPU metadata from SL mkv/ts/m2ts/mp4/hevc/rpu files ), then I drag the hevc file and then it asks me: Enter which frame you want to read and press enter... and this is where I don't know how to continue.
Where do I get the frames that I have to enter?
Thank you very much and greetings.

This is not important if all you want is to extract the RPU. Just enter any number. I'll add an option to skip that in the next version.
By the way, you should update your version of the scripts
we are now at 1.3.1

maybe you can add HDR10 to DV also for mp4remuxed already, split stream to have hevc DV, and mp4remuxed again or not.
I must mp4demuxed or remuxed all to mkv first to get madVR in 1.3.0. but it is ok.
anyway it;s nice script you have. thank you.

just for curiousity: what is --dv-bl-compatible-id 1 or --dv-bl-compatible-id 2 for --dv-profile 8

ok will add next version. good suggestion.

just for curiousity: what is --dv-bl-compatible-id 1 or --dv-bl-compatible-id 2 for --dv-profile 8

it tells if the base layer is compatible with SDR/HDR10/HLG/BD or none
but this function doesnt work with the mp4muxer I use.

Thank you very much friend, with version 1.3.1 everything works perfectly, I can now extract the RPU.bin and inject it into another source.

Thanks for bringing DGDemux to our attention. It looks promising but one gotcha is that it has an option to keep the AC3 core with the THD (which we need for X800M2 compatibility) but using that disables the seamless gap processing. So to use the gap processing we'd have to re-add the AC3 core afterwards (presumably re-encoding from the gap-fixed THD), and then remux again so we'd still be at the mercy of tsMuxer bugs

For your information, recent versions of DGDemux have fixed this issue. When demuxing TrueHD, three files are created: *.thd, *.ac3, and *.thd+ac3. All three files have proper gaps correction. Also, the distribution includes a utility called thdmerge, that can be used to combine a *.thd and a *.ac3 into a *.thd+ac3.

I recommend using the latest version 61.

There's a FW update for the x700. Nothing regarding HDR or DV, though.

Is there a good way to spot check whether a DV P5 video base layer and an HDR10 video have the same (or similar enough) light levels for the metadata to be compatible for the hybrid maker functionality?

[Jose1001]

Hello again, I still have a question.
Why is it that when I extract the RPU.bin with the DoVi_tools script from a dvhe.05.06 profile, and add it to a BDRemux with HDR, it creates a dvhe.05.06 BL+RPU + HDR10 compatible profile, and not a dvhe.08.06 profile?
Thanks and regards

Because you can't just extract/inject the P5 RPU untouched into an HDR10 video. The rpu must be synced and converted to P8.
Check the tutorial videos.

Personally, I just compare the PQ images. I use MPV to export lossless png.
I might include a drag and drop mode for that in my next version.

Press S to get a lossless PQ PNG

Code: Select all

mpv.com --target-trc=pq --target-prim=bt.2020 --vo=gpu-next --gpu-context=d3d11  --screenshot-format=png --screenshot-png-compression=1 video.mkv

Thanks! That's really helpful. I ended up doing

Code: Select all

mpv --vo=gpu-next --target-trc=pq --target-prim=bt.2020 bd://mpls/800 --bluray-device=[path to blu-ray folder]

in one maximized window and

Code: Select all

mpv --vo=gpu-next --target-trc=pq --target-prim=bt.2020 [path to DV MP4]

in another.

That way I could quickly jump to a few different points in the movie, find the equivalent frame in the other window, and then flip back and forth to verify the brightness was the same.
