ignoring any bitrate differences, in terms of just 'dolby vision dynamic effects' - if the original uhd is only mel and not fel, then there shouldn't be any real difference between a 'p8 custom' and 'uhd mel'DolbyVisionFTW wrote: ↑Thu Apr 14, 2022 7:46 pm@RESET_9999 or indeed any other knowledgeable person regarding Dolby Vision.
Is there likely to be any difference in video quality between a retail 4K UHD Blu-ray release that includes Dolby Vision and a Hybrid release combining the non-Dolby Vision 4K UHD Blu-ray plus RPU from a Dolby Vision WEB-DL of the same title?
Thanks.
I've noticed there is likely to be a difference.staknhalo wrote: ↑Thu Apr 14, 2022 9:10 pmignoring any bitrate differences, in terms of just 'dolby vision dynamic effects' - if the original uhd is only mel and not fel, then there shouldn't be any real difference between a 'p8 custom' and 'uhd mel'DolbyVisionFTW wrote: ↑Thu Apr 14, 2022 7:46 pm@RESET_9999 or indeed any other knowledgeable person regarding Dolby Vision.

Wondering if that would work. I have never tried to remux 7.1 EAC3 from a blu-ray to mkv or mp4. Would the different build-up be accepted by either container?RESET_9999 wrote: ↑Thu Apr 14, 2022 2:11 pmNot ideal but you could just convert the bluray to P8, demux 7.1 audio with tsmuxer, and then build your P8 mp4 with 7.1 audio.
I absolutely agree. In my early days of cross-injecting RPU, I've experienced significant differences between some HDR10 baselayers with P5 RPU and their native P7 RPU. I wonder if it's because of the different colorspace, or that P5 DV videos are a totally different DV grade because of whatever streaming-service reasons.
Anyone using the metadata from profile 5 files to "hybrid" should be comparing the PQ image to the regular profile 7 HDR10 version.ArArdin wrote: ↑Fri Apr 15, 2022 11:59 amI absolutely agree.

"dvhe.07.06" means that it's Dolby Vision Profile 7, which is the format used on discs. So those are probably just rips of discs that have Dolby Vision and not what we call hybrids here. What we call hybrids are rips where the HDR10 video is taken from a disc, and then the DV is added from another source (usually a Web-DL), and those are usually (maybe always?) distributed as Dolby Vision Profile 8 files.daylightcreative wrote: ↑Fri Apr 15, 2022 9:30 amI have been scanning through this thread and find it fascinating and rather insightful. I've pulled down a few "HDR format : Dolby Vision, Version 1.0, dvhe.07.06, BL+EL+RPU" hybrid releases only to find they don't play in my setup.
Looking at @RESET_9999's awesome DV playback device summary spreadsheet, I see that the Shield Pro does partially support Profile 7 rips, but they have to be "single-track dual-layer", and yours are presumably "dual-track dual-layer". So you can convert them, but I'm not sure what the right tool for that is. The downsides of the Shield Pro are that it doesn't support FEL (the "Full Enhancement Layer" extra video data which is found on some DV discs and is of debatable importance), and it has some long-standing color inaccuracy issues when playing Dolby Vision.daylightcreative wrote: ↑Fri Apr 15, 2022 9:30 amAll three have an NVIDIA Shield Pro 2019 connected to them
Of course. In my post I was talking about comparing "Dolby Vision enabled playback" views.
I just tried and it works in all the containers ( mp4 / mkv / ts) ... mkvtoolnix even keep the core intact (unlike the TrueHD tracks)

Have you tested the Xiaomi 4k stick with DV yet, any good results?mtotheb wrote: ↑Thu Jan 27, 2022 12:24 pmHas anybody tried the new https://www.mi.com/global/product/xiaomi-tv-stick-4k/
it seems to officially support HD Audio (DTS HD) as well as Dolby Vision. When I receive mine i’ll test if FEL playbacks correctly while also having HD Audio Passthrough.
Theres tutorial video in my scripts link. check out the bluray to profile 8.1 one.redoine322 wrote: ↑Sat Apr 16, 2022 2:26 amCould you plz explain to Me how to get an mp4 or mkv file to work on my LG C1 with DV please using your script From BDMV thanks for your hard Work Sir
