Re: Dolby Vision now possible through MP4 Mux.

I have LG C7 and I also have these artifacts in some movies. It is not because of DV or a HDD, but because of the player in TV. It cause artifacts also on the remuxes or on the m2ts files from ISO. It's too bad that LG didn't fix it on new model (also someone should try it on C7). I fixed this by b...

Re: Dolby Vision now possible through MP4 Mux.

Hi. Which movie did you watch and what kind of artifacts did you notice? As for the lag I discovered that it could be very likely caused by the hard drive itself. I once encountered terrible lag using on hdd but when I changed it to another it was fine. I watched Mortal Engines. I create the .mp4 f...

Don't waste your time with TLJ or other Disney releases. They have a "fake" DV track that is just there so they can claim their discs have DV and trigger TV's to show DV. The track on TLJ is just 76MB, whereas all other discs have DV tracks between 2 and 10GB
Is this true? To date I only tried Justice League which had less than 60 MB DV track and honestly I couldn't find any difference which the HDR10 version (Both remux and m2ts).
If this claim is legit so what are the best DV movies I can try? I recently got US but I haven't watched it yet...
Not true. There's no "fake" DV.
4K UHD Bluray discs use Dolby Vision Profile 7 (dual layer).
There are two type of Dolby Vision Profile 7.
1. DV Profile 7 with MEL (Minimal Enhancement Layer)
2. DV Profile 7 with FEL (Full Enhancement Layer)
MEL contains dynamic metadata for HDR. And FEL contains dynamic metadata + data from the original HDR master for full 12-bit color.

Paramount, Universal and Lionsgate are known to exclusively use FEL. (only exception from Lionsgate was their recent Robin Hood release. This used MEL).
Warner and Disney are known to use MEL. (The only exception was 2001 A Space Odyssey from Warner and Black Panther from Disney. These two used FEL).

Why don't you try Braveheart (Paramount)? This is known to be a reference standard transfer and contains FEL. For some reason, I can't get Braveheart DV mp4 to play on OLED. It's HDR10 and 4K Bluray disc play fine though. Can you make a Braveheart DV mp4 and report back your findings?
Thanks 🙏🏻
I'll try Braveheart and I'll report here

Tried this with Last Jedi UHD. Don't waste your time with TLJ or other Disney releases.
