Could you let me know which rpu I should use for Presence (2024)? There are 3 of them in your folder. Thanks.

Presence.2024.2160p.AMZN.WEB-DL.DDP5.1.HDR.H.265 Generated T3.xml
Presence.2024.BD Generated T3.xml
Presence.2024.BD_Generated_T3 (frame by frame).xml

Can you please explain how FEL interacts with generated DV?

I assume that if you generate your own DV the FEL gets discarded. However, some of your RPU releases say "movie name P7 FEL Only Generated T3 OSC" and now has me second guessing on how it works.

one is the usual shot by shot for amazon
one is the usual shot by shot for the bluray disc
and the last one is frame by frame because this movie has very long shots so you should use this one

Nothing gets discarded. I just replace the L1-L2 and add L3 L8 L9

So it's possible to replace all levels in a P7 FEL RPU? The FEL layer isn't "tied" to L1?

Interesting detail: based on my tests, cm_analyze is deterministic - for the same input and arguments, the generated RPU is always identical.

As long as you reconstruct the master for the DV analysis.
FEL contains the difference between the master and the HDR10 encode, which can be fully restored with the dovi_baker.

DV windows update is available outside the DEV mode, and surprisingly, it does true TV-LED.
Win10 still has the red push bug though.

For older TV, you might have to modify your EDID but I heard you can use the LG dolby access app to enable it.

Fascinating. I wonder if we'll see player updates on Windows to enable Dolby vision playback. That'd be sweet.

Well, Energy Player can already do DV MKV + lossless audio as well as P7 to P8 playback, but that would be nice with MPC-HC/BE + some sort of dovi_baker plugin for FEL... It might be possible one day...

For me personally I'm thinking jriver mc support. It would definitely be ideal, especially with fel.

Why the dolby vision mode toggle doesn't work outside lg tv? It's possible to enable this on other brand tv like philips?, I have the toggle on windows but It does nothing.

My G5 has a DV PC mode and is seen as DV capable on Windows. Without it, DV is not triggered, so you'll probably have to modify your EDID, see: https://github.com/balu100/dolby-vision-for-windows
