Dolby Vision now possible through MP4 Mux.
Re: Dolby Vision now possible through MP4 Mux.
Hello,
I'm new to this forum. I've been reading this thread. Trying to get an understanding. However I'm a bit lost. Hopefully my question is relevant to this thread. Apologies if its not. I did try to search for an answer or clues to how I may be able to solve my issue. Any help would be greatly appreciated.
I recently bought a used TV, TCL 55R615. It has Dolby Vision and HDR.
My friend gave me a Dolby Vision MKV movie for me to play on this tv using PLEX. However from what I've researched. DV MKV files don't seem to work on TCL tvs with PLEX.
However I found this forum and thread. I downloaded a demo DV MP4 file. And my tv did trigger DV.
Is it possible to take the movie I have and change it over to MP4 to play it in DV mode? If so, could you please let me know what I have to do? Thanks

The Ryan DV DL 07.06.mp4 did trigger DV in PLEX for my TCL tv. Looked Great. So did the mkv HDR10 file.agneva wrote: ↑Thu Jan 14, 2021 6:43 amDid you try my Samples? https://www.makemkv.com/forum/viewtopic ... 25#p103529

The Ryan DV SL 05.06.mp4 did trigger DV but the scene was almost all dark.

Re: Dolby Vision now possible through MP4 Mux.
Does the method in the OP still work with the lg oled CX's internal player? Or we have to use some other methods, given all the recent discussions surrounding that tv?
Re: Dolby Vision now possible through MP4 Mux.
HDR10 should look right, the sky is very smooth
SL 05.06 should look wrong, too dark and the light sky is pumping.
DL 07.06 should look right, no pumping and very fine grain
On CX9LA internal player SL+DL is the same, because the internal player ignores EL.
Do you use Plex on your TCL TV internal ?
Re: Dolby Vision now possible through MP4 Mux.
Yes I use the plex app on the TCL TV. The mp4 works great. But when it comes to my friends DV MKV file. DV won't trigger. What I'd like to do is change the container to DV MP4. But I'm very new to this and don't know the steps to get to it. If its even possible to get to it.agneva wrote: ↑Fri Jan 15, 2021 7:04 amHDR10 should look right, the sky is very smooth

Re: Dolby Vision now possible through MP4 Mux.
Thanks for the sample files. I played them on my CX with internal player and HDR picture looked so much brighter, but DV (both profile 5 and 7) looked darker but the overall picture felt a bit sharper (and more detailed ) compared to HDR. Do you think only the internal player ignores EL? I tried with plex, but didn't find any difference between internal player and plex.agneva wrote: ↑Fri Jan 15, 2021 7:04 amHDR10 should look right, the sky is very smooth

Re: Dolby Vision now possible through MP4 Mux.
Is that an issue?
EDIT: I just played all 3 of your test files on my C9 (not CX). The DV SL file looks wrong with some kind of duplicated images overlaying each other. The DV DL file and the HDR10 file, however, play fine and look right. So there's sth wrong with the internal player of the CX since you said the DV DL and DV SL file look the same on your CX? That's surprising considering the CX is the newer model compared to the C9. I also heard someone say that was fixed in the latest firmware?
Re: Dolby Vision now possible through MP4 Mux.
Of course there is an issue.
If you see the white sky is pumping / picture is to dark, the (F)EL is not decoded !
in my opinion the CX can only decode the Metadata (RPU) of DV, not the second HEVC stream.
maybe the older LG TV can do, I don´t know... to find out, I uploaded the samples for you.
