  1. madVR is certainly very impressive... zombie10k AVS Forum Addicted Member Join Date: Dec 2007 Posts: 12,940 Mentioned: 169 Post(s) Tagged: 1 Thread(s) Quoted: 5432 Post(s) Liked: 5811 check out the feedback of MadVR from @W.Mayer in Germany, he has one of the largest home theater screen setup's I've seen. He runs a Barco 4K 6P with a massive 7.3 meter wide by 2.95 meter high screen (~24 feet wide, ~9.6 feet tall!) http://dci-forum.com/d-cinema-hi-end...sg6431#msg6431 I wonder what HSTM settings @madshi was using for the demo? Spoiler!
  2. If you see JVC,s DTM then madVR,s HSTM and Lumagens DTM ....you will very quickly realise that the JVC DTM is ( yes its free , thats great ) is still a huge compromise.. I have used all 3.... The JVC DTM is a great effort.....but dont kid yourself its anywhere near the level of madVR or the Lumagen..
  3. Al..... if you were to see just what madVR or a Lumagen can achieve with HDR i think you would be very surprised. You can very easily run HDR as low as 50nits and still get a fantastic image. Because you are mapping to a known brightness , madVR ( Or Lumagen) is able to use 100% of your actaul light output for the mapping. The new JVC DTM is OK...but its still a huge compromise.
  4. JVC,s DTM .... a critical flaw..

This means that it is picking the range bucket it is using based on information that may be wrong or represent a very small amount of the actual content. This is why there is definitely NOT a one size fits all mode for any piece of content and why Auto won't always give great results for everything. JVC should have ignored metadata completely and use the frame analysis to determine the right tone map. On top of that, it needs to have a way to allow the end user a way to inform the tone mapping how much light it actually has to work with. Without that, it is always going to be compromised because the projector never knows how much light it has to map to, regardless of the mode used. Yes the results are still far better than before, and better than any other projector is doing, but it could definitely be better if approached in that way. I have updated the article to reflect this and I've given this input to JVC. Hopefully at some point we'll see those type of improvements. This is how MadVR and Lumagen work (though they approach it in different ways) and the results definitely show how it can improve the image.

Bingo! And that is exactly what I just did! And you know what, JVC AND I WERE WRONG! The Auto mode is definitely switching which mode it uses based on the metadata presented (and defaults to MED if none). I tested this with the Spears and Munsil disc first as it is the only disc I know of that can actually change metadata on the fly within the same grade. But I wanted to be absolutely sure, which led to ANOTHER revelation. I had been testing this with my Radiance Pro in the loop by creating a pure passthru memory that was doing nothing at all to the signal (no tone mapping, calibration, scaling, nothing). BUT, what I found out is that Lumagen had a bug that was manipulating the output metadata to something OTHER than what the disc was putting out (confirmed by the input info on the Lumagen and the input info in the JVC). So the reason I was seeing MEDIUM was because of this manipulation! BUT, it also gave me a way to directly test whether the same frame would use the same mode if I fed it to the projector either thru or not thru the Lumagen (disc metadata proper vs Lumagen metadata wrong). And it would select a different mode. So which one it choses is directly tied to the metadata, NOT the analysis of the frame. I've already informed Lumagen about the metadata bug. The only way to even know it was doing this is if you had a display that showed the metadata on the input side, to compare with. So I was wrong and JVC was wrong as well. I will reach out to them and give them tests to verify. I will also update my article to reflect this mistake. VERY SORRY FOR ALL THE CONFUSION!!! Quote: Originally Posted by DLCPhoto It would be interesting to hear their what they say as to whether or not this is a one-time determination, based on the initial incoming signal, or if it would change the assignment to low/medium/high as the incoming signal might change enough later on in the movie. I tried this as well using the Spears and Munsil demo, which goes from really bright scenes to really dark scenes and it always stayed in the mode it selects the first time, so it is pre-assigning the range bucket to use based on this information (or it defaults to medium if no info, which is what it uses for the MaxCLL around 1000 nits so it is the safe bet). Quote: Originally Posted by Dominic Chan You may be looking at the post by Jue Liang. In my case, it was the projector that switched from Natural to HDR10 when it detects HDR metadata. I then manually switch it to FA HDR. If the video stream goes back to SDR, the projector switches back to HDR10, which is NOT the last thing I selected manually. Gotcha, it treats the HDR10 mode as the last selected mode. Again, this process was not designed to work with people changing the settings within a mode. Just realize that if you change the mode AT ALL, you're going to need to reset the SDR mode back. If you just set it and leave it alone, it works just fine.

  7. The MOST important aspect ... sadly, sometimes forgotten by "Audiophiles"..
  8. A great review showing just how good madVR is..... Ekki , Anna and Florian compared MadVR , JVC,s DTM and Sony,s effort.. Alone madVR in its latest version really offers a fully automatic HDR adjustment without the necessary additional "trimming" and was therefore also the winner of the day. Any perfectionist who does not shy away from the hassle of PC installation and configuration is therefore recommended to make friends with madVR.
