Thanks — useful details. HLG in MediaInfo plus Films & TV showing the same files over‑exposed (while VLC/MPC‑BE look normal) strongly points to an HDR/HD‑Color tone‑mapping problem in the Windows playback pipeline. Below are step‑by‑step checks and fixes (copy/paste commands included) — follow them in order and tell me which step changes anything.
Why this is happening (short)
- Films & TV uses the Windows HDR/HD‑Color pipeline and will apply tone‑mapping when a file presents HDR metadata (HLG/HDR10). That can make HLG files look blown out if tone‑mapping or system HDR settings are incorrect. Turning HDR off usually fixes it; there are additional app/driver/codec and registration issues that can keep the app behaving badly even when “Use HDR” is toggled.
Quick checks (try these first)
1) Confirm HDR settings and try a reset toggle
- Settings → System → Display → (select your HDR monitor) → Windows HD Color settings (or search “HDR settings”).
- If “Use HDR” is OFF now, toggle it ON, then adjust the “SDR content brightness” (HDR/SDR slider) until the image looks reasonable, then toggle HDR OFF and test again. This “on→adjust→off” flow sometimes clears the wrong tone‑mapping state. If the file looks correct with HDR ON after lowering SDR brightness, that confirms tone‑mapping is the issue.
2) Test other players
- You already said VLC and MPC‑BE look normal — that confirms the file is fine and the problem is Films & TV / Windows HDR handling.
If the quick checks didn’t fix it, do the deeper fixes below.
A — Update drivers & codecs
- Update your GPU driver (NVIDIA/AMD/Intel) to the latest WHQL from the vendor website.
- Install the HEVC and AV1 extensions from the Microsoft Store if the files use those codecs (sometimes the app falls back to a different decoder that behaves poorly). These steps resolve many playback/tone‑mapping quirks.
B — Reset the Films & TV app (GUI)
- Settings → Apps → Apps & features → Films & TV (Movies & TV) → Advanced options → Reset.
- Test files after the reset.
C — Re‑register / reinstall the app (PowerShell)
Run PowerShell as Administrator and copy/paste the commands below.
1) Check whether the package exists:
Get-AppxPackage -AllUsers *ZuneVideo*
If it returns package info you’ll see InstallLocation.
2) If package exists, re‑register it:
Code:
Get-AppxPackage -AllUsers *ZuneVideo* | ForEach-Object {
Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)\AppXManifest.xml"
}
What to expect
- If successful the app will reappear in Start and should behave as a freshly registered app. If you see deployment errors (HRESULTs like 0x80073D06, 0x80073CF9, etc.), copy the error text (or any ActivityID GUID) and paste it here so I can interpret it. The forum KB contains the same re‑register approach and common followups.
D — If Add-AppxPackage complains about “previous application data”
- Rename the per‑user package folder to force the app to recreate its state:
1) Close Films & TV.
2) Open Explorer and go to:
%LocalAppData%\Packages
3) Find the folder that starts with Microsoft.ZuneVideo_ and append “.bak” to the folder name (this preserves it but removes it from the app’s view).
4) Retry the re‑register command above. (Renaming clears app settings — you’ll lose any per‑app preferences, but it often clears blocked registrations.)
E — System repairs (only if registration fails with low‑level deployment errors)
- Run these in an elevated command prompt:
Code:
DISM /Online /Cleanup-Image /RestoreHealth
sfc /scannow
Reboot, then retry re‑register. These commands repair Windows component store problems that can block app registration.
F — Workarounds if you just need correct playback now
1) Convert HLG → SDR (lossy copy) — permanent solution for Films & TV:
- If you don’t need HDR, convert the file to SDR using ffmpeg (creates a new SDR file that all players will display normally). Example ffmpeg one‑liner (adjust paths and filenames):
ffmpeg -i "input.mkv" -vf "zscale=primaries=bt2020:trc=bt2020-10:matrix=bt2020_ncl,tonemap=hable,zscale=primaries=bt709:trc=bt709:matrix=bt709" -c:v libx265 -crf 20 -preset medium -c:a copy "output_sdr.mkv"
- This tone‑maps HLG to Rec.709 SDR so Films & TV (and other SDR‑only renderers) show correct brightness. (If you want a version using libx264 or different tuning, tell me and I’ll give that variant.)
2) Use another player that handles HLG correctly
- Continue using VLC, MPC‑BE, mpv, or PotPlayer for these files — they already display correctly on your system. If you want an app that mimics Films & TV folder traversal plus correct HDR handling, PotPlayer and mpv are good picks (mpv can be scripted to autoload a folder in Explorer order).
What I need from you if the above doesn’t fix it
- Paste the output of Get-AppxPackage -AllUsers ZuneVideo (run the check command and paste the text here). That tells me if the package exists and the InstallLocation.
- Tell me your Windows version (Settings → System → About → OS Build) and GPU make/model (Device Manager → Display adapters). That helps determine driver or OS‑level HDR handling problems.
- If you want, upload a short MediaInfo text dump of one problematic file (MediaInfo’s “Text” or “View → Text” output) so I can confirm exactly which HDR signalling is present.
Quick suggested order to run right now
- Toggle HDR ON → adjust SDR slider → toggle HDR OFF and test.
- Update GPU driver + HEVC/AV1 extensions.
- Reset Films & TV (Settings → Apps → Reset). Test.
- Run Get-AppxPackage -AllUsers ZuneVideo and if present re‑register using the command above. If errors, paste them here.
If you want, I can:
- Provide an ffmpeg command tuned to your quality/format preference.
- Interpret any PowerShell Add-AppxPackage error you paste here.
- Give a one‑click PowerShell script that performs the check → rename package data → re‑register sequence safely and logs results.
Which do you want to try next?
