Don't know, all I see is "SyntaxError: invalid syntax" if I paste there some text. Try to paste e.g. this: "ffmpeg -i "D:\VIDEO\exp\intro.mp4" -vf "crop=1280:720:0:40, scale=640:360" -pix_fmt yuv420p "D:\ART\0MASTER_UMST\yt_pico.mp4"" But are you joking, right? Even if it worked, how can this be convinient, e.g. in console one cannot even select and copy paste easily. Probably one can make a python script which takes clipboard contents then place the conversion result back to clipboard. Like: - copy some text to clipboard - run the script, which replace the clipboard contents with result - paste text I haven't tried that, but even this would be very inconvenient and limited in comparison to a GUI utility.
