Powershell automated conversions

Post by Rocketcandy » Wed Sep 14, 2016 4:32 pm

I have written a powershell script that will convert files in 2 specified directories over a given size.

It is on Github for easy updates and can be found here: https://github.com/Rocketcandy/ConvertUsingHandBreakCLI

If you have questions or thoughts please let me know!

Code as of 9/14/16 is below:

Code: Select all

####  Change values below to match your enviroment #####

### Specify Directories below ###

# TV Shows directory
$TvShowDir = "C:\Path\To\Episodes"

# Movies directory
$MovieDir = "\\File.Server\Path\To\Movies"

##### Changes Below here are optional #####

### Change file size if desired below ###

# Look for TV Shows larger than this value
$TvShowSize = 1GB

# Look for Movies larger than this value
$MovieSize = 2GB

### Change file format to desired format, defaults to .mkv"

#File format must be either mkv or mp4
$FileFormat = "mkv"

##### These can be changed but will default to the extracted folder and the 64bit install of handbreak #####

# Spreadsheet containing completed conversions information. Do not change unless you want it to go to a differnt path
$ConversionCompleted = ".\ConversionsCompleted.csv"
    $ConversionCompleted = Resolve-Path -Path $ConversionCompleted

# Directory you want log files to go to
$LogFileDir = ".\Logs"
    $LogFileDir = Resolve-Path -Path $LogFileDir

# HandBreak Instillation directory (The directory that has HandBrakeCLI.exe in it) 
$HandBreakDir = "C:\Program Files\Handbrake"


### Check to make sure all paths and files exist before starting ###

# Create the Conversion Completed Spreadsheet if it does not exist
If(-not(Test-Path $ConversionCompleted)){
    $headers = "File Name", "Completed Date"
    $psObject = New-Object psobject
    foreach($header in $headers)
     Add-Member -InputObject $psobject -MemberType noteproperty -Name $header -Value ""
    $psObject | Export-Csv $ConversionCompleted -NoTypeInformation
    $ConversionCompleted = Resolve-Path -Path $ConversionCompleted

# Create the Logs directory if it does not exist
    New-Item -ItemType Directory -Force -Path $LogFileDir | Out-Null
    $LogFileDir = Resolve-Path -Path $LogFileDir

# Check to see if HandbreakCLI.exe exists in $HandbreakDir
    Write-Host "HandBrakeCLI.exe not found in $HandBreakDir Please make sure that HandBreak is installed.  Quitting" -ForegroundColor Red
    Read-Host "Press Enter to exit..."

# Check to see if $MovieDir exists
    Write-Host "Movie directory: $MovieDir not found.  Please make sure the path is correct.  Quitting" -ForegroundColor Red
    Read-Host "Press Enter to exit..."

# Check to see if $TvShowDir exists
    Write-Host "Tv Show directory: $TvShowDir not found.  Please make sure the path is correct.  Quitting" -ForegroundColor Red
    Read-Host "Press Enter to exit..."

#Create Hash table to check against before starting conversions.  This will prevent converting items that have already been converted (This spreadsheet updates automatically)
$CompletedTable = Import-Csv -Path $ConversionCompleted
foreach($file in $CompletedTable){
    $HashTable[$file."File Name"]=$file."Completed Date"

#####  Start looking for files and converting files happens after here #####

# Output that we are finding file
Write-Host "Finding Movie files over $($MovieSize/1GB)GB in $MovieDir and Episodes over $($TvShowSize/1GB)GB in $TvShowDir be patient..." -ForegroundColor Gray

# Find all files larger than 2GB
$LargeTvFiles = Get-ChildItem $TvShowDir -recurse | where-object {$_.length -gt $TvShowSize}  | Select-Object FullName,Directory,BaseName,Length
$LargeMovieFiles = Get-ChildItem $MovieDir -recurse | where-object {$_.length -gt $MovieSize}  | Select-Object FullName,Directory,BaseName,Length

# Merge the files from both locations into one array and sort largest to smallest (So we start by converting the largest file first)
$AllLargeFiles = $LargeTvFiles + $LargeMovieFiles | Sort-Object length -Descending

# Run through a loop for each file in our array, converting it to a .$FileFormat file
foreach($File in $AllLargeFiles){

    # Just the file itself
    $EpisodeName = $File.BaseName
    # The final name that we will rename it to when the conversion is finished and we have deleted the original

Is there any restrictions on the filelevel depth under the directories?

ex. file01/file02/files03/video.avi.

Excited to try this out and reclaim some space.

You specify they base directory that includes all the files you want to convert even if there are several levels of folders.

It will go through and find all the files over the size you specify and then convert them from largest to smallest.
