Inconsistency on HDR support

ddutra · July 25, 2022, 5:15pm

Hello,
I am having trouble understanding why I don’t have HDR for some of my files.
Please note that when I write that “I have / don’t have HDR for this file” it means Infuse is showing the HDR or DV tag on the UI.

A) Why does samples 2, 3, 7, 14 and 15 have no HDR while 8, 11 and 13 have HDR?
B) Why does sample 10 does not fallback to HDR while samples 4, 5 and 9 fallback to HDR correctly?
C) Why does sample 1 does not fallback to HDR while sample 12 does?
D) Isn’t DV Profile 08 supported? If yes, why sample 1 is not recognized (dvhe.08.06)?

Please find the mediainfo data attached for samples 1 to 16. I suppressed the Audio information.

dvhe.08.06 - HDR10

Thanks for the help.

What type of device are you streaming from?

Are you using Plex, Emby, or Jellyfin?

If playing these files, are you able to see Infuse switch to the correct mode (with correct colors) on your TV?

With regard to DV, Apple devices support a very limited number of DV profiles. For unsupported types, Infuse will fallback to HDR. More info on this can be found in this post.

Sorry for the lack of information. Here it goes.

Apple TV 4K connected to LG C9 65"

Nope. Infuse directly playing from NFS share.

For the files that I marked as working I see the apple tv “Dolby Vision” or “HDR” logo on the top right corner. For everything else, nothing pops up but the video plays just fine. No weird colors etc…

Thanks for the quick reply.

Would you be able to upload a sample or two of the problematic videos we can review here?

If you want to clip out a short segment to make the uploading files smaller, you can follow the steps here.

James
I am uploading some files named ddutra-sample-x.mkv.
Files were split using mkvmerge --split.

ddutra · July 25, 2022, 8:20pm

James,
I imported the files on my mbp 2022 Infuse app and it shows HDR to all sample files.

When I get home I will do the same on the Apple TV 4K.

@james I guess the problem could be the NFO files?
I did not know that Infuse used the nfo files to determine the quality of the video. I was under the impression that it always read the video file.

Case in point, Ad Astra on my Movies library. The file has a NFO on the same directory and is displayed as 4K no HDR.

SAMPLE
    <video>
        <aspect>1.77777779</aspect>
        <bitrate>47942584</bitrate>
        <codec>HEVC</codec>
        <framerate>23.976</framerate>
        <height>2160</height>
        <scantype></scantype>
        <width>3840</width>
        <duration>123.04</duration>
        <durationinseconds>7382</durationinseconds>
      </video>
      <audio>
        <bitrate>3387772</bitrate>
        <channels>0</channels>
        <codec>TrueHD Atmos</codec>
        <language>English / English / English</language>
      </audio>

But when I split the 1 minute sample (same I sent you) and put it in a blank folder with no NFO, Infuse read it and recognized the Movie (!!HOW? the title is sample-x.mkv) and recognized as HDR 4K.

So I guess the movie is really HDR? The mediainfo is as below:

Is it good practice to just get rid of all NFO files and let Infuse sort the library? My movies are within folders correctly named as {Movie Title} {Year}.

james · July 27, 2022, 3:02pm

NFO files shouldn’t affect this.

Can you try using the Edit Metadata option on one of these files and reselect the correct title.

You can also move the NFO file (temporarily) and edit metadata to see if anything changes.

ddutra · July 27, 2022, 3:11pm

OK so I deleted NFO file for Ad Astra, used the Edit Metadata option to re-select the movie title and it now shows as HDR.

Tried the same with another file but without touching the NFO file, just using the Edit Metadata trick.

Before (NO HDR):

After (HAS HDR):

Before doing any of this I had deleted all my metadata, unchecked all my folders in the Library and forced a new scan.

ddutra · July 27, 2022, 3:14pm

Thinking about this, could this be a problem with my NAS always upgrading my files?

Let’s say a movie gets released. I download the first available release, which sometimes may not have HDR/DV. Infuse scans and picks up the movie.
A few days later, new release, higher quality and with HDR. My NAS downloads it automatically.

But in such case, shouldn’t a full library/metadata scan do the trick?

james · July 27, 2022, 3:22pm

Can you upload one of the (complete) NFO files here?

Maybe one from both a working and non-working file?

ddutra · July 27, 2022, 3:46pm

Inception as it is now:

Inception.2010.2160p.UHD.BluRay.REMUX.HDR.HEVC.DTS-HD.MA.5.1-EPSiLON.nfo (7.3 KB)

Inception after Edit Metadata Trick:

NFO is unchanged.

Now for a file that has been working from the get-go:

The.Godfather.1972.2160p.UHD.BluRay.REMUX.DV.HDR.HEVC.TrueHD.5.1-EPSiLON.nfo (8.1 KB)

Thanks

james · July 27, 2022, 6:41pm

Thanks for that!

I wasn’t able to replicate this here with the NFOs, and all of your other uploaded files were tagged correctly as well.

These 3 files are using all of the same 1min HDR sample, and your NFO files for the 2nd and 3rd titles.

Since the issue appears to resolve itself when reloading metadata for the affected files, I guess that would be a solution for any remaining files which are affected.

Perhaps the original issue stemmed from Infuse not fully completing its indexing, or perhaps starting to index files that were in the process of being copied/transferred between locations. It’s hard to say.
