Batch converting files to monochrome I am looking for a free software that lets me convert a batch of video files to monochrome.
The closest I've found so far is Any Video Converter free but this does neither allow for easy application of a setting to all files within the queue, nor does it allow to keep the original file format (e.g you can't convert from webm to webm and just apply a filter).
I do, however, want to keep all properties except for color.
Okay I just did with a ffmpeg batch
In PowerShell:
ls | Where { $_.Extension -eq &quot;.webm&quot; } | ForEach { ffmpeg -i &quot;$i&quot; -vf &quot;hue=s=0&quot; -crf 20 -codec:a libvorbis -c:v libvpx -b:v 500k &quot;${name}.webm&quot; }
