I'm trying to figure out what PowerShell command [or script if necessary] might allow
ffmpeg to recursively traverse a directory, pull stills via the
-vf flag, and put all the stills into a folder without any filename conflicts that would cause overwriting.
So I know that this works fine for an individual file:
ffmpeg -i input.mov -vf fps=10/60 still%04d.jpg
The files generated start from
still0001.jpg and count up to
I have a directory that looks like this, with video files at different levels:
I'm trying to use a PowerShell command that can pull stills from all the videos
video4.mov and drop them into one folder.
I found a PowerShell command that purports to have ffmpeg traverse a directory recursively, but when I try to adapt it, it's not working.
PS T:\Exports\1 - Dailies\stills test> for /F "tokens=*" "%G" IN ('dir "T:\Exports\1 - Dailies" *.mov') do ffmpeg -i "%G" -vf fps=10/60 still%05d.jpg
But I get this error:
At line:1 char:4 + for /F "tokens=*" "%G" IN ('dir "T:\Exports\1 - Dailies" *.mov') do f... + ~ Missing opening '(' after keyword 'for'. + CategoryInfo : ParserError: (:) , ParentContainsErrorRecordException + FullyQualifiedErrorId : MissingOpenParenthesisAfterKeyword
Where am I going wrong?
