Another new FW on the horizon. Supposedly improves the DTM even more
No, I mean something newer than this one. And the change in the new version is even more significant than this 110120 version, I would say I saw a substantial change in DTM in the upcoming firmware.
Concerning the next update with even more improvement for the already spectacular DTM:We are close to the next big release.This release improves the "back and forth" scenes cuts which were difficult. Pat said the second time the same scene shows in a number of the cases actually does have different levels. The DTM was over emphasizing the difference, but Pat has found ways to adjust the DTM algorithm to keep the back and forth scenes as close as possible.There were also a few scenes that had other issues. One type of scene I know about had enough areas with bright objects to fool our zone-based analysis. Pat redesigned the zone analysis, which improved these scenes.I just discussed timeframe for the next release with Patrick. He said he is working on a couple additional scenes and thinks we can post the next release this weekend.======Usage comment for the upcoming release:As we have seen in the past changing the algorithms can also change the recommended defaults. Let me first say that the current recommendations (Max Light = 4 to 6 times measured light in nits, Dyn Pad = 2, Low-ratio = 31) still work well. That said, I am planning to change my settings slightly based on viewing the results of DTM for this upcoming release.Max Light: I have been at 5x (400 for a measured max of 78 nits) for our Lumagen Demo Theater RS4500. With the new release I prefer setting Max Light 6x measured max. This helped with some bright details (e.g. Mad Max: Fury Road sand storm scene explosions).Dyn Pad: We changed to a recommendation of 2 (from 5 to 6) a while back. This was due to changes in the algorithm allowing the scene headroom to be reduced. The effect of Dyn Pad changes slightly in the upcoming release. In my viewing, IMO the Dyn Pad of 2 seems to reduce the headroom slightly from the previous release. Patrick said there were not intentional changes to the Dyn Pad headroom, but he said he did change the MaxCLL effect on calculations He said this could affect Dyn Pad. Dyn Pad of 2 still looks great for most scenes but one scene I found where I wanted a higher Dyn Pad was "The Meg" in the "Hatch scene" with the red haze in the hatch (this is in teh first couple minutes of the movie). For this scene I ended up preferring Dyn Pad = 5. I also found I preferred Dyn Pad = 5 for Mad Max, and for several other title. The difference in scene brightness between 2 nd 5 seems less to me, and I saw more bright detail changing Dyn Pad to 5.I should note that I already have discussed this with Pro owners using the current release and suggested Dyn Pad = 5 in some cases. So this is not entirely new. Dyn Pad remains a trade-off between higher scene brightness (=2) and more detail in very bright objects (=5). This has not changed, but my preference has. I am currently thinking I will set Dyn Pad = 5 for the upcoming release. So, my recommendation is try 2, 3, 4, and 5 for Dyn Pad over a lot of material and then select your preference.I am not changing Low Ratio or DeSat settings for this new release.I hope this is helpful to everyone and that I have not opened a can of worms as my posts sometimes do.
Hard to imagine it can look much better, after watching " Captain Marvel " on 4K Blu-ray last night with friends. it's looking pretty amazing now!
