How to run a ffmpeg command in Powershell and pass variables to it?

Question

I would like to run the following command in Powershell: ffmpeg -i "VIDEO.mp4" -i "AUDIO.m4a" -c copy -map 0:v:0 -map 1:a:0 "OUTPUT VIDEO.mp4"

But I would like to browse for the files. I have tried this:

Add-Type -AssemblyName System.Windows.Forms 

$VideoBrowser = New-Object System.Windows.Forms.OpenFileDialog -Property @{ 
    InitialDirectory = $PSCommandPath
    Filter = 'Video file (*.mp4)|*.mp4|All files (*.*)|*.*'
    Title = 'Choose video file'
}
$null = $VideoBrowser.ShowDialog()
if (!($VideoBrowser.FileName))
{
    return
}

$AudioBrowser = New-Object System.Windows.Forms.OpenFileDialog -Property @{ 
    Filter = 'Video file (*.m4a)|*.m4a|All files (*.*)|*.*'
    Title = 'Choose audio file'
    RestoreDirectory = $true
}
$null = $AudioBrowser.ShowDialog()
if (!($AudioBrowser.FileName))
{
    return
}

$NewVideoBrowser = New-Object System.Windows.Forms.SaveFileDialog -Property @{ 
    Filter = 'Video file (*.mp4)|*.mp4|All files (*.*)|*.*'
    Title = 'Save new video file as'
    RestoreDirectory = $true
}
$null = $NewVideoBrowser.ShowDialog()
if (!($NewVideoBrowser.FileName))
{
    return
}

And all these ways to run the command but all fail:

$ArgumentList = '"{0}" -i "{1}" -c copy -map 0:v:0 -map 1:a:0 "{2}"' -f $VideoBrowser.FileName, $AudioBrowser.FileName, $NewVideoBrowser.FileName;
Start-Process -FilePath ffmpeg.exe -ArgumentList $ArgumentList -Wait -NoNewWindow

OR

$ArgumentList = '"' + $VideoBrowser.FileName + '" -i "' + $AudioBrowser.FileName + '" -c copy -map 0:v:0 -map 1:a:0 "' + $NewVideoBrowser.FileName + '"'
Start-Process -FilePath ffmpeg.exe -ArgumentList $ArgumentList -Wait -NoNewWindow

OR ffmpeg.exe $VideoBrowser.FileName -i $AudioBrowser.FileName -c copy -map 0:v:0 -map 1:a:0 $NewVideoBrowser.FileName

What should I try?

I had forgotten the -i in the beginning of the arguments!

This works: ffmpeg -loglevel debug -i $VideoBrowser.FileName -i $AudioBrowser.FileName -c copy -map 0:v:0 -map 1:a:0 $NewVideoBrowser.FileName
