function Edit-Media { <# .Synopsis Edits media files .Description Modifies media files to apply advanced filters .Notes Edit-Media will return the output file, which can in turn be piped into the next Edit-Media. Each parameter set of Edit-Media will perform one and only one action. Using Edit-Media in a fluent pipeline will allow you to easily control the order in which actions are applied. .Example Get-Item a.mp4 | Edit-Media -FadeIn | Edit-Media -Rotate 90 .Link Convert-Media .Link Get-Media .Link Get-RoughDraftExtension #> [CmdletBinding(DefaultParameterSetName='None',SupportsShouldProcess)] [OutputType([IO.FileInfo])] param( # The input path [Parameter(Mandatory,Position=0,ValueFromPipelineByPropertyName)] [Alias('Fullname')] [string[]] $InputPath, # The output path.
