Dolby Vision now possible through MP4 Mux.

Re: Dolby Vision now possible through MP4 Mux.
When taking FEL screenshots with DoViBaker in AvsPmod, is there a good way to tone map to SDR? I've tried the default generated script as well as applying the 100-nit L2 trim to DoViBaker through "trimPq=2081, targetMaxNits=100, targetMinNits=1". Both look too washed out compared to CAH's 100-nit conversion. https://slow.pics/c/l7iEtcS3

I guess you would have to add libplacebo in the script.axeyou wrote: ↑Sun Sep 24, 2023 12:48 amWhen taking FEL screenshots with DoViBaker in AvsPmod, is there a good way to tone map to SDR?

You can use 7-5-3 (madVR +MPC) which has the best HDR to SDR tone mapping anyway.
Code: Select all
LoadPlugin("D:\DoVi_Scripts\tools\DoViBaker_x64.dll")
LoadPlugin("D:\DoVi_Scripts\tools\dgdecnv_242\DGDecodeNV.dll")
LoadPlugin("D:\DoVi_Scripts\tools\avs_libplacebo.dll")
bl = DGSource("D:\\P7_BL.dgi")
el = DGSource("D:\\P7_EL.dgi")
DoViBaker(bl, el, rpu= "D:\\P7RPU_FEL.bin")
libplacebo_Tonemap(src_csp=1, dst_csp=0, dynamic_peak_detection=true, tone_mapping_function=0, tone_mapping_mode=1)

Re: Dolby Vision now possible through MP4 Mux.
I'm trying to inject HDR10+ metadata into an HR10 remux. However, the HDR10+ metadata is delayed by 24 frames.
How do I sync them? I'm familiar with syncing with dovi_tool, but I'm afraid it won't work with HDR10+.

Thanks, RESET! libplacebo looks much better!RESET_9999 wrote: ↑Sun Sep 24, 2023 1:53 pmI guess you would have to add libplacebo in the script.

Do you also happen to know how to apply it to BL only? It looks like it doesn't accept a DGSource("BL.dgi") as input:
Code: Select all
LoadPlugin("D:\DoVi_Scripts\tools\dgdecnv\DGDecodeNV.dll")
LoadPlugin("D:\DoVi_Scripts\tools\avs_libplacebo.dll")
DGSource("D:\Movies\\00009\00009_BL.dgi")
# libplacebo_Tonemap: failed uploading data to the GPU! Trying alternative RGB32 conversion. Attempt failed !
libplacebo_Tonemap(src_csp=1, dst_csp=0, dynamic_peak_detection=true, scene_threshold_high=-1)

Re: Dolby Vision now possible through MP4 Mux.
it works fine on my end
btw I added support in the latest dovi_scripts workflow 7-1 for SDR tone mapping line 119 set tonemap=0

Re: Dolby Vision now possible through MP4 Mux.
Thanks again, RESET! I guessed I just hit some bug. Restarted AvsPmod and it worked fine : )
Appreciate your help!

Re: Dolby Vision now possible through MP4 Mux.
Does anyone know what streaming services provide the best quality Dolby Vision? I've been told different streaming services offer different quality Dolby Vision metadata. Do we have a list of streaming services what provide what features?

Re: Dolby Vision now possible through MP4 Mux.
The L1/L2 metadata is most of the time exactly the same on all the streaming services. Only iTunes is slightly different with the static color reshaping, missing Level 4 and 5
I've seen newer cmv4.0 DV analysis(new L1) on streaming service MAX compared to iTunes old cmv2.9 but most of the time, it's the same.

Re: Dolby Vision now possible through MP4 Mux.
since I bought Resolve I don't want to share the preset anymore sorry but...
''hdr to sdr'' preset is the same as the ''DV generation'' settings, you just deliver the 100nits trim.
sdr to hdr:

Re: Dolby Vision now possible through MP4 Mux.
I have been blindly converting hundreds of my Dolby Vision UHD BDs to Profile 8 for compatibility, but now I am starting to wonder if there is a point. When I compare the Profile 7 and 8 results in Plex on either the AppleTV or Shield they look the same. Now I can't see them side by side, but am I just wasting my time or is there a benefit maybe I am just seeing? At this point the only advantage I can easily recognize is DV playback with Infuse on the AppleTV with the Profile 8 conversion (albeit it doesn't always work).
Re: Dolby Vision now possible through MP4 Mux.
I am exactly in that position and didn’t convert my DV UHD BDs bcoz I wanted to convince myself objectively that I wasn’t loosing on PQ even if if can’t see a difference (even just MEL ones). This topic is quiet complex, I think one has to do pretty much the same amount of work and diligence that RESET9999 did to start reaching an understanding.Balthazar2k4 wrote: ↑Sat Sep 30, 2023 12:28 amI have been blindly converting hundreds of my Dolby Vision UHD BDs to Profile 8 for compatibility, but now I am starting to wonder if there is a point.

One approach is to use DV test pattern(s) and compare the performance of a reference DV player (Oppo 203) with ATV4K DV performance (by taking accurate photos of the screen), and that of Infuse or other DV software capable media streamer. I attempted to do this & you can find good reading starting w this https://forum.makemkv.com/forum/viewto ... 63#p135163 and the next few posts and replies from RESET9999.
One conclusion (whether significant or not), and dismissing any errors in the experiment, is that using that P8 DV test pattern, the Oppo shows elements of that test pattern that ATV (internal player) nor Infuse doesn’t. How does this reflect on PQ and what a human perceives during movie playback is a subject beyond me.
Maybe the convenience of having all digital media being available under the control of a streamer software (Infuse, …) trumps whatever PQ difference there may be. I’ll redo what I did w tvOS17 which brings P8 internal playback support.

Re: Dolby Vision now possible through MP4 Mux.
It it possible to skip ProRes generation while converting HDR10+ to DV (using 3-1) or is it just better to use the old method if I want to do it quickly?
