Dolby VS10 - Confused

Hi Guys/Experts.
I am writing this after reading tons about the Dolby VS10 and instead of understanding it better I got more confused about it.

I have the Z9X 8K , Denon AVR-X3800H (7.1.4 speakers layout) and 75' TCL C935 TV
Connectivity matrix: Z9X 8K -> AVR -> TV
My TV and AVR both supports HDR, HDR+, HLG & DV (IQ).
I use Kodi (21) as my only Media player

What I am struggling to understand is: In what Use case I should use/set the VS10 (it's relevant to try it out)?

 

It may be better to leave everything on Auto as the PQ from these boxes is great and your TV supports all HDR flavours. I use VS10 to convert SDR to DV. No other reason than I like the way it looks!

 

Any thing? Any one?

 

VS10 only supports if you use zidoo player.

 

I know that and it supports it. but that is not what I asked....
Would you care reading my question again and answer what I asked (to make it easier for you, read the last line in my original post)?

 

Hi, long story. For me, VS10 is a software program which is making your video more brighter and shaper - look more digital for me as well. You can try to set it in setting display, and see if you like it or not.
If you only use kodi as media player, you should use ZDMC which is kodi mod version from Zidoo. It uses zidoo player instead of kodi player. So you can only get benefit from VS10 if you use zidoo player.

 

really? the VS10 in Zidoo video settings menu is a player settings and not a system settings?

 

VS10 is Dolby's universal playback engine.

It can be used to convert between SDR, HLG, HDR10(+) and Dolby Vision, eg. HDR10 > Dolby Vision or used simply to enhance a format, eg HDR10 > VS10 HDR10.

Uniquely, when converting Dolby Vision to SDR or HDR10 it uses the Dolby Vision RPU metadata in the conversion in a similar way to how Player led Dolby Vision (LLDV) works.

 

Why would someone want to convert a DV or HDR native content to an SDR? or DV native content to HDR10? for what use case?
it's like doing a downgrade..

 

If your display doesn't support the content format. Particularly useful for projector owners or non DV displays (eg Sansung).

 

but all those formats supposed to be backwards compatible. for example if your display only supports HDR then the DV content would be displayed/played in HDR.
same for SDR, if a DV content is played-back on an SDR display it would be projected as SDR. what am I missing here that you still need to convert it via VS10 if the native content is backwards compatible

 

No, that's not the case at all.

 

well, it is the case in my situation. on my older TV (different TV at my bedroom) that only supports HDR all DV content is play back in HDR.
and on my computer monitor which is not HDR all DV content is play back as SDR.
also that is what Dolby declare that it is backwards compatible.

 

Profile 7 contains an HDR10(+) base layer so is backwards compatible with HDR10(+). Profile 5 is not backwards compatible with any other format.

Neither are backwards compatible with SDR and without outboard conversion will play in the wrong colour space with the wrong gamma.

(Profile 4 has an SDR base layer so is backwards compatible with SDR and not HDR10(+) but Profile 4 is never used commercially).

 

OK, that starting to make more sense now (thanks for the more in depth details).
just a question, Profile 5, where is it used usually? is it a popular one? for example BR uses Profile 5?, Netflix/Disney+ what profile they use? is Profile 8 backwards compatible (HDR/SDR)?
if I have a DV movie/file, is there a way/tool that can present me the info what DV profile it is complied with?
do you have a list or a web site that provides DV profiles and what they are compatible with? very similar to what you responded on P7 , P5, P4

 

Profile 5 is used for Dolby Vision streaming (Netflix, Disney et al)
Profile 7 is used for UHD BluRay
Profile 8 is not used commercially mainstream but tends to be used by people creating so called "Hybrid" files - taking the RPU from a P5 online stream and stitching it to an HDR10 UHD BluRay release. Not usually a good idea.

This is a list of all Dolby Profiles, but as I say, only 5 and 7 are in mainstream commercial use.

Profile 4 - dual layer (HEVC) with SDR base layer
Profile 5 - single layer (HEVC) DV proprietary, no compatibility
Profile 7 - dual layer (HEVC) with an HDR10(+) base layer
Profile 8 - single layer (HEVC) which can be SDR, HDR10(+) or HLG
Profile 9 - single layer (AVC), SDR
Profile 10 - single layer (AV1) which can be DV proprietary, SDR, HDR10(+) or HLG
Profile 20 - single layer 3D (MV-HEVC/HEVC) DV proprietary, no compatibility

You can tell the profile from a Media Info report or by pressing "info" on the remote and selecting "More"

You'll see "dvhe.*.*"

The *.* is profile.level

for example, dvhe.07.06 which translates as Dolby Vision HEVC Profile 7 Level 6

(the level essentially defines the resolution and frame rate)

 

thank you!!! very helpful...

 

In fact the latest version of MediaInfo tells you verbosely like this:

Dolby Vision, Version 1.0, Profile 7.6, dvhe.07.06, BL+EL+RPU, no metadata compression, Blu-ray compatible / SMPTE ST 2086, Version HDR10, HDR10 compatible

Since you are the expert in this device, is it correct @Kenjamin0523 statement that the VS10 settings in the Zidoo video settings menu (you know, the one you select to convert different type of formats using VS10), is only applicable if you use the Zidoo built-in player and will not take effect if you use an external player on the device? such as Kodi?

Yes that's correct.
