But i never found out why, some files works other not.

Eh!? LG televisions don't support HDR10+ decoding. In much the same way, Samsung televisions don't support Dolby Vision decoding. They should both fall back to playing regular HDR10...

Can anyone tell me how to put the HDR metadata into the DV file with bigger bitrate to make a hybrid?

I know it's just one day and I know I insist, but if anyone could really help me out, I'd appreciate it. I know how to make a hybrid as in adding DV to HDR, but not the other way around. Is it not possible?

I'm assuming your DV file is Profile 5. Profile 5 color space is different from that of HDR (IPTPQc2 which is Dolby proprietary vs BT.2020), so I don't think there is an easy way for you to make a Profile 5 HDR compatible. BTW the difference in bitrate almost certainly won't be noticeable during playback, unless one is 50 Mbps and the other 2 Mbps.

HDR10+

HDR10+ signals the dynamic range and scene characteristics on a scene-by-scene or even frame-by-frame basis. The display device then uses the dynamic metadata to apply an appropriate tone map through the process of dynamic tone mapping. Dynamic tone mapping differs from static tone mapping by applying a different tone curve from scene-to-scene rather than use a single tone curve for an entire video.

For offline and video-on-demand (VOD) (e.g. ultra-high-definition Blu-ray, over-the-top (OTT), multi-channel video programming distributor (MVPD)), HDR10+ metadata may be created during the post-production, mastering process or during transcoding/encoding for distribution back-ends by HDR10+ content generation tools in two steps,

1. Identifying scene cuts, and
2. Performing an image analysis on each scene or frame to derive statistics

HDR10+ metadata is interchanged through a low complexity JSON-structured text file, which is then parsed and injected into video files.

What's that about ??

Dolby Vision Hybrids

Dolby Vision, Version 1.0, dvhe.05.06, BL+RPU

Yep, it's Profile 5.

Well, crap. Guess I'll have to keep two versions then.

Thanks for your help, by the way

You could extract the RPU from the DV, convert it to Profile 8.1 and inject it into the HDR to get a hybrid HDR10 DV, that way you won't have to keep both files. That's if you're OK with the lower bitrate of the HDR one.

Also, are there any plans to have all the DDVT options as Drag 'n' Drop (like the new Hybrid option) ??, makes it SO much easier

Yes. Working on an enhanced All in One Script. Takes only some time ...
