I use Nvidia Shadowplay to capture 4K HDR clips. These play as expected in VLC and Windows 11 Film & TV.

I'm trying to use Davinci Resolve v19 to edit these, and even though the timeline preview has the correct colours, the output will not play as HDR no matter what combination of settings I use.

Using MediaInfo, the settings look practically identical, so I cannot understand the problem. I've tried using ChatGPT, YouTube tutorials, etc, but nothing has worked.

Resolve project settings (unsure why HDR Metadata is greyed out): enter image description here enter image description here enter image description here

Resolve export settings (changing Data Levels to Full doesn't make a difference): enter image description here enter image description here

I think I've found that, despite all of the options being there, the free version of Davinci Resolve in fact does not support exporting HDR.

I've worked around this by using FFmpeg instead. Sample PowerShell command:

$FFMPEG = "<path to ffmpeg.exe>"; $FFMPEG -i "<path to input MP4 file" -ss 00:02:32 -c copy "<path to output MP4 file>";

Edit 2025/05/20:

I've now created a PowerShell script to make this easier:

$FFMPEG = "$Env:userProfile\<path to ffmpeg.exe>" while ($true) { do { $folderPath = Read-Host "`nEnter input folder path" $folderPath = $folderPath.Trim('"', "'") if (-not (Test-Path $folderPath -PathType Container)) { Write-Host "`tFolder not found. Please try again." -ForegroundColor Red } } while (-not (Test-Path $folderPath -PathType Container)) $extensions = @('.mp4', '.mkv', '.avi', '.mov', '.flv', '.wmv') $videoFiles = Get-ChildItem -Path $folderPath -File | Where-Object { ($extensions -contains $_.Extension.ToLower()) -and (($_.BaseName -split ' - ').Count -eq 2) } if (-not $videoFiles) { Write-Host "`tNo unprocessed video files found in folder. Please try another folder." -ForegroundColor Yellow continue } Write-Host "`tFound $($videoFiles.Count) unprocessed video file(s) to process." for ($i = 0; $i -lt $videoFiles.Count; $i++) { $file = $videoFiles[$i] Write-Host "`nProcessing file $($i + 1) of $($videoFiles.Count): '$($file.Name)'" Start-Process $file.FullName do { $action = Read-Host "`tTrim or delete? (t/d)" if ($action -notmatch '^[TtDd]$') { Write-Host "`tEnter 't' or 'd'." -ForegroundColor Red } } while ($action -notmatch '^[TtDd]$') if ($action -match '^[Dd]$') { # Immediately delete original without further prompts $shell = New-Object -ComObject Shell.Application $shell.Namespace(0xA).MoveHere($file.FullName) Write-Host "`tDeleted to Recycle Bin" continue } # Trimming workflow do { do { $rawStart = Read-Host "`tStarting timestamp (MM:SS, e.g. 00:30)" if (-not $rawStart -or $rawStart -notmatch '^\d{2}:\d{2}$') { Write-Host "`tInvalid or empty timestamp.
