Thank you! The same thing, choose the BL and EL, keep desired sound files with subs, and go either with TS or M2TS? I just hope it will be in profile 7 automatically. BTW, which is better, TS or M2TS for X700?

yep, just remux straight to TS or M2TS, both work fine and yes it will be dual-layer profile 7.

Ts is smaller.
BUT
Try to remux Apocalypse now Final Cut or Spartacus with tsmuxer and you will get a file which can be played on X700, but X700 shows you that the file is 0:00:00 "long" and you cannot fastforward...

In case of Spartacus, I found a solution: I splitted it to two parts (in addition I cutted out some blank frames from the middle). Maybe, it will work for you too...

Guys I would like to ask you to do some more pixelhunting :lol:

Here is Valerian test file (FEL) https://gofile.io/d/mpgn5a

Please compare it in HDR/DV mode on Shield. Take a close look on 0:33 mark
I wonder can you spot any difference in gradients around these areas on gun? :roll:

I can't bring myself to even look at screen shots of that movie much less a video of it. :D I saw it in the theater and hated it. Never have a desire to witness it again in any form. LOL

No need to compare anything anymore. The Shield just can't play the uhd-bd rips accurately yet.
I've been watching some Netflix on my shield (finally) with the vertex lately. It looks great.

We are not even 100% sure whether it's discarding the the second layer or not, correct? So many questions about Shield and no answers. Had high hopes! BTW, thank you for your hard work testing and posting videos/screenshots here!

no way to tell for sure until they fix the color issue.

Today a pleasant discovery.
In the Spears & Munsil UHD HDR Benchmark disc I found two Dolby Vision versions (FEL and MEL) of the same file.

I had never come across the same file encoded in two different ways.
It could prove to be an important step to reverse the Dolby algorithm and allow FEL -> MEL conversions.

Now smart people have to play "spot the difference" (I personally use HEVCESBrowser for a quick visual analysis).

For those who want to play, here are the files (40 sec cuts):
BL + EL & RPU (FEL)
BL + EL & RPU (MEL)

For those who want to view on the TV the files in question, use as always the tools you have available (mp4muxer, tsMuxer, MakeMKV, my tool, etc...) to create either Single Track and Dual Layer files or "classic" Dual Track and Dual Layer files.

Ah hell, I never even thought of that aspect. We've been playing with these files for a few weeks now to test the SHIELD. It never even occurred to me that FEL->MEL conversion would be helped by this. But, um, yea!

I watched them multiple times with the inbuilt player on my C7 and without a doubt I can clearly see the difference. FEL has more detail and the colors are more punchy.
I won't settle with a MEL only support media player that's for sure.
I'll wait a few more months to see if the Shield color problems are fixed, and accurate playback of FEL content is confirmed but if not I guess it's time to buy a ChinOPPO.
