Apply File Creation Time as TimeCode

tc.ps1

mkdir tc
$files = Get-ChildItem * -include @("*.mp4", "*.mov")
foreach ($file in $files) {
  $fileDate=(Get-Item $file).creationTime
  $dateParts = $filedate -split " "
  $fileParts = $file.Name -split "\."
  $fbname = $fileParts[0]
  $fext = $fileParts[1]
  $ftime = $dateParts[1]
  $fbase = $file.BaseName
  $cm = " C:\Users\Jason\Downloads\ffmpeg-4.3-win64-static\bin\ffmpeg.exe -i $file  -vcodec copy -timecode $ftime```:00 tc/$fbname-tc.$fext"

  echo $cm
  iex $cm
  $newFile = Get-ChildItem tc/$fbname-tc.$fext
  $newFile.CreationTime = $file.CreationTime
  $newFile.LastWriteTime = $file.LastWritetime
  $newFile.LastAccesstime = $file.LastAccesstime
}

For updating the timecode of a video file based on the file creation date. Not as good as proper timecode / clapboard, but at least gets you started. Run in the same directory as the source files, a subdirectory 'tc' is created and all input files placed there.
