I don't know why I was convinced otherwise !
Thanks for enlightening me!
And above all, thanks for having glossed over the rest of what I write !
I bet my posts make people's eyes bleed (especially native English speakers)!
I apologize again...
I don't know why I was convinced otherwise !
I prepared the 2 files as per your request. One is untouched FEL and the other is MEL converted using Yusesope latest tool and instructions. Both files are in m2ts made with tsmuxer "w64-nightly-2020-09-20--02-24-10" and originate from the UHD disc "US". Both files play perfectly in sony x700.RESET_9999 wrote: ↑Wed Sep 23, 2020 12:53 pm@ragico
if it's not too much trouble for you, could you please upload two small samples so I can do some comparison. I need one untouched dual-layer FEL sample and one dual-layer converted MEL sample that plays on the x700.
I'm not sure of which tool I need to extract layers of a single layer file(bl+el+rpu).
thank you
Many thank's . I'll do some comparisons tonight.ragico wrote: ↑Wed Sep 23, 2020 3:52 pm

It is a wise choice! The important thing is to stay informed!
Thanks for what you do! And thanks also to @ragico...
This is not the only reason but it can help you understand.
I also believe that this is probably the expected behavior. When FEL is processed correctly, it's produces a 12bit picture whereas MEL is only capable of 10bit. Even though we don't have 12bit displays, a 12bit stream downsampled to 10bit will still look different than a native 10bit(MEL) stream. A picture and picture comparison of the original FEL vs converted MEL may not then a be a good way of determining whether the method is working. One thing you can potentially try is since the S&M disc contains a demo that's provided in both FEL and MEl, convert the FEL to MEL and then compare it to the provided untouched MEL.RESET_9999 wrote: ↑Wed Sep 23, 2020 11:29 pmthe untouched FEL is brighter & has more punch, no doubt. But I think this is normal because I'm seeing the same kind(if not more) of difference when I compare the Spears and Munsil FEL & MEL
On the other hand when I use TsMuxeR (version given in your procedure w64-nightly-2020-09-20--02-24-10) to integrate the audio tracks and pgs, TsMuxeR changes me the Dv 8 profile into Dv 7 profile, which him does not pass on my Tv, and therefore the video is read in HDR PQ.Général

There are multiple reasons why the FEL structure is intact in my MEL files.RESET_9999 wrote: ↑Wed Sep 23, 2020 11:29 pmalso from the bluray discs I inspected, FEL DV hevc stream is the actual movie with a white/grey tint on it while MEL DV is just a static white/grey image. We still can see the video in the MEL conversion so that could be the reason why it doesn't play on the x700.
True!RESET_9999 wrote: ↑Wed Sep 23, 2020 11:29 pm...I can add some random MEL track to any HDR10 hevc stream and it will still play in DV (single or dual layer). with some flickering but it triggers DV...

keep in mind that those pictures are amplifying the difference... the clipping here is introduced by the camera, there is no clipping in real life.
I'm not very familiar with your tools because my player can play dual layer DV so i dont really know how to convert/extract it.yusesope wrote: ↑Thu Sep 24, 2020 11:07 am

I don't want to take advantage of your kindness @RESET_9999!
Also keep in mind that my RPUs carry more information than those normally found in MEL streams.
Maybe the result could be in favor of the converted MEL file over the original MEL.
Or it could be a complete disaster...
I had imagined it. I trust your judgment.RESET_9999 wrote: ↑Thu Sep 24, 2020 12:49 pmkeep in mind that those pictures are amplifying the difference... the clipping here is introduced by the camera, there is no clipping in real life.
I'm sure you would say that you prefer the FEL one if you saw it in real life. Not a big difference but i can tell fel is more vibrant.
This hurts my little heart
I have encountered several difficulties in making the cut.RESET_9999 wrote: ↑Thu Sep 24, 2020 12:49 pmIf someone can upload a small MEL conversion sample of that spears and munsil disc, I can compare it to the original MEL file.
thank you! I'm at work all day, I will compare tonight.
