How do you use VS10?

    When reading about this device I saw a lot of talk about the benefit of the VS10 engine and it's superiority over things like the Shield.

    But in further reading I am seeing many (like the best settings guide) recommend "auto" to send native HDR and DV. Which has me kind of confused. Is VS10 mainly used for tone mapping on devices that don't support HDR or DV?

    Do you use VS10 and if so in what way? Thanks

    VS10 is the Dolby Vision engine so in addition to converting to Dolby Vision, it's used any time Dolby Vision itself comes into play whether it's converted or not.

    How you use it depends on how you want to view content - personally I convert everything to LLDV because that gives me the best image I've ever seen on my projector. I also use it on my Samsung TV - which are great for Dolby Vision by the way ;)

    Another big advantage is in vastly reducing, if not eliminating HDMI syncs but it all depends how you want to view your material - Auto gives you all things native and it depends on the display (SDR, HDR, DV) as to when VS10 kicks in.

    Thanks thats helpful, I like the HDMI sync part, that is definitely an added benefit.

    My setting on VS10 is at for HDR and SDR content. Reasons (I have DV and HDR capable 4K TV connected) :
    1. You will be able to play HDR+ content as DV on your TV which may not be able to play HDR+
    2. SD and HDR contents gets processed to DV , I see very good improvement.

    YES it is in general.
    I set up ALL HDR and SDR to VS10 and leave DV as native
    In my opinion VS10 greatly enhance the pic quality even on excellent HDR content

    I got Pana ZJ2000 and although very good of upscaling and the Professional mode close matches VS10 engine I still will switch over VS10 for a movies
    In my liking VS10 for everything but native DV

    If you have a DV display, VS10 always outputs DV natively - what else would it do?

    Bringing this thread back up. Just purchased a Z9X Pro and was figuring out optimal settings. It seems like I should move away from "Auto" in favor of using the VS10 chip even for HDR content.

    That is correct!

    VS10 convert (very good) all content to DV and in case you play a DV content than VS10 just passthrough it as native DV. You will not be disappointed as long as your TV supports DV.

    Does anyone know a bit more in depth on how exactly it converts to DV? Is it just a DV container? Does it force LLDV onto non-DV content? Can it actually make use of metadata from HDR10+? Does it create its own dynamic metadata? If so, how? I've actually never really understood this. Thanks!

    Thanks, but I was specifically interested in the conversion to DV through VS10. Any other information would be great.

    I suspect Dolby would hold most of the info as business-in-confidence.

    I've been running VS10 on all content SDR + native HDR/DV content. For the latter case, PQ is absolutely amazing.

    My tip is to create 2x Dolby Vision profiles on your TV. Using LG as an example, on native HDR/DV content I use Cinema (Home) with brightness at 100. HDR/DV content has metadata that tells the TV when to hit peak brightness, but average brightness is lower.

    But for SDR-DV with VS10, I have another profile with brightness at 75. All other settings identical to Cinema (Home).

    I find that though the VS10 engine does a great job on colors, SDR brightness is too high if left on DV default settings. Should be lowered to match the 100nits that SDR is graded on. Adjusting the brightness lower to match calibrated SDR brightness at 100nits renders the picture much better.

    I guess really all I am trying to understand is if the VS10 engine is creating tonemapping metadata based on analyzing the non-DV file? Like does it try to come up with dynamic metadata for SDR/HDR10/HDR10+ content? If so, how decent is the metadata? That's what I'm most interseted in.

    In short. Unless @Markswift2003 has anything to add, no, it's static, and....it's a black box, so who knows what's really going on under the hood.

    Some like it, others not so much, so it's all to down to personal taste I guess.

    Exactly that - it's programatically a black box.

    If you like what it does, use it, if not, don't.

    Since it's programmatically a black box, the only way to test VS10 is empirically. This user/thread is great, and he looks at a few frames in different flavors :

    The results are quite nice. SDR to HDR looks comparable to native HDR, and much better than SDR to me. Colors on VS10 are much nicer. Whatever mapping VS10 does with the BT.709 > BT.2020 conversion is good. I find the gamma mapping not quite as good, but I compensate by lowering the TV brightness, which I find gives the illusion of helping.
