Automated powershell script

[tranquilcarbon]

Hey everyone, I've created a powershell script that should be able to automate the running of the CLI.

# Preset variables
$ntscRsCliPath = "C:\Programs\ntsc-rs-windows-standalone\bin\ntsc-rs-cli.exe"   # Location of the CLI
$presetFilePath = "C:\Programs\ntsc-rs-windows-standalone\Presets\Default.json" # Preset location
# User set variables
$inputFolderPath = Read-Host -Prompt "Enter a folder path" # Prompt the user to enter a path

$videoFiles = Get-ChildItem -Path $inputFolderPath -Filter "*.mp4" | Where-Object { $_.PSIsContainer -eq $false }   # Get all video files in the input folder

foreach ($file in $videoFiles) {
    # Construct the output file path
    $outputFileName = "$($file.BaseName)-NTSC-RS.mp4"   # Output saving format (For example, Me at the zoo-NTSC-RS.mp4)
    $outputFilePath = Join-Path -Path $inputFolderPath -ChildPath $outputFileName   # Makes path to output to

    # Main script
    Write-Host "Processing "$file.BaseName""    # Show what is currently processing
    $command = "& `"$ntscRsCliPath`" -i `"$($file.FullName)`" -o `"$($outputFilePath)`" -p `"$($presetFilePath)`" --scale 576"  # the CLI command itself:
    # === Explaination ===
    # $ntscRsCliPath - The path to NTSC-RS CLI
    # $file.FullName - The name of the file to run the command on
    # $outputFilePath - The final output export location
    # $presetFilePath - Where the preset is located
    # --scale - How big the video is, in lines, for example, a 4:3 video at 
    # 576 scale will render at 768x576.
    Invoke-Expression $command # Run the command
}

Hope this helps!

I've updated this script to be able to run two "passes".

# Scale information
#===TAPE===
# S/VHS (PAL/SECAM) = 576
# S/VHS (NTSC) = 480
# Betamax (NTSC) = 480
# Betamax (PAL/SECAM) = 576
# SuperBetamax (NTSC) = 480
# SuperBetamax (PAL/SECAM) = 576
#===Disc===
# CVD (NTSC) = 352x480
# CVD (NTSC) = 352x576
# DVD (NTSC) = 720x480
# DVD (PAL) = 720x576
# UMD = 480x272
#===Broadcast===


# Preset variables

$presetFilePathStage1 = "C:\Programs\ntsc-rs-windows-standalone\Presets\Betamax.Digital.json"  # This filter will be applied on the first run
$presetFilePathStage2 = "C:\Programs\ntsc-rs-windows-standalone\Presets\Default.json"   # This will be applied on the second run
# User set variables
$inputFolderPath = Read-Host -Prompt "Please enter a folder path" # Prompt the user to enter a path
Write-Host "Using NTSC-RS installation located at "$ntscRsCliPath""
Write-Host "Using Preset "$presetFilePathStage1" (Stage 1)"

# Get all video files in the input folder (you can change the filter as needed)
$videoFiles = Get-ChildItem -Path $inputFolderPath -Filter "*.mp4" | Where-Object { $_.PSIsContainer -eq $false }

    # Stage 1: Run ntsc-rs-cli with stage 1 preset

    Invoke-Expression $commandStage1

    $outputFileNameStage2 = "$($file.BaseName)-NTSC-RS-Stage2.mp4"
