I’ve always used the dovitool tool (now I’m using 0.51) saving the rpu file, removing the metadata (hdr+ and DV) from the original and with the file without DV I inject the previously saved rpu file, so they all go to infuse 7.5 .
Previously I had problems with version 0.52. it didn’t create the mkv file for me.
Looking for some help… I am on the latest - Infuse 7.5 - and not seeing DV enable on the TV. I only see HDR.
Apple TV 4K - older model (2017)
Here’s the MediaInfo - I see it says DV, but I’m not sure which number is the profile:
HDR format : Dolby Vision, Version 1.0, dvhe.07.06, BL+EL+RPU, Blu-ray compatible / SMPTE ST 2086, HDR10 compatible
An absolutely awful idea. It needs setting once for your own preference and then you can forget about it.
If you want only true Dolby Vision set it to limited.
For files that cannot truly play back as Dolby Vision it will play as HDR.
If you want to see that Dolby Vision logo on your tv even if it’s actually playing fake Dolby Vision then set it to auto.
I do get your confusion however. For me Auto in most circumstances implies a logical/best/optimal setting.
In this particular case it’s the setting that nobody should be using. Why anyone would want fake Dolby Vision I have no idea.
Bottom line though, as I said, set it once and forget about it.
The problem is that there are some DV8 files that cannot be predetermined and that is why these three options exist instead of two. Files that play in auto and not in limited can be “real” DV and not “fake”. But with auto you could also be enabling “fake”
What about files (as in my above workflow UHD MEL P7 to P8) ? It triggers DoVI in both Auto/Limited where I assume Infuse is “processing” it on the fly to a P5, call it fake or hybrid or whatever… (as P8 transfer function is PQ vs P5’s IPT)
This needs a makeover, especially regarding “other P8”… From Infuse playback settings:
Extended Dolby Vision (Applies to DoVi Profile 8 only)
Auto (prefer compatibility) - Convert P8 to P5 (when possible), and attempt to play other P8 as P8 via the system player (output will usually switch to DoVi) Q1: Why the mention of “system player” here but not in Limited ? what’s system player: ATV player vs Infuse Player ?
Limited (prefer accuracy) - Convert P8 to P5 (when possible), and play other P8 as HDR (output will switch to either DoVi or HDR depending on the video) Q2: What does it mean: other P8 play as HDR but the output will switch to either DoVi or HDR depending on video ? If a video plays as HDR, should it not be detected and play as HDR ?
Off - Ignore all DoVi details and play P8 as HDR (output will always switch to HDR)
Since Dolby Vision Profile 8 is supported now, is it possible to add auto-convert Profile 7 to Profile 8 by ignoring EL and just applying RPU? Kodi has a build that can do it on the fly so no need to pre-process video files from P7 FEL/MEL to P8.
It’s actually more nuanced than that. There are files which cannot be played as P5, but can be played as P8. Some of these will play as DoVi, and some will not. Apple provides no documentation for their black box, so it’s hard for us to tell how some of these files will be handled.
Auto will give you more real DoVi, but may also show some fake DoVi.
Limited will prevent any fake DoVi, but you may be missing out on some real DoVi.
We may look into it, but it would probably push us into an area where license questions come into play (and it’s unlikely Dolby has a license option for this kind of workflow).
I was more referring to recognition before actual playback. Often, files will have MediaInfo data available about them before they are downloaded, and whether or not they will play as intended is a pretty big factor to consider when building a library.
