ffmpeg batch edit please help friends

[Matador]

Hi friends please help, i have many holiday recordings in camera, recorded with date logo printed in error. I want to remove logo from video, like this

ffmpeg -i DSC_001.avi -vf delogo=x=160:y=560:w=319:h=79 -c:v libx264 -crf 24 -c:a copy -preset ultrafast DSC_001.avi

But i possess +350 DSC video, how to process all videos at once? thanks friends!

for /f %v in (*.avi) do ffmpeg -i %v -vf delogo=x=160:y=560:w=319:h=79 -c:v libx264 -crf 24 -c:a copy -preset ultrafast %~nv_delogo.avi

If you put this in a batch file, the percent signs must be doubled.

JVRaines thanks friend, but that produces

bash: syntax error near unexpected token `%v'

You didn't specify your operating system. I gave you a command for Windows, which is what most folks around here are using. In Linux,

for filename in *.avi; do
     ffmpeg -i "$filename" -vf delogo=x=160:y=560:w=319:h=79 -c:v libx264 -crf 24 -c:a copy -preset ultrafast "$(basename "$filename" .avi)_delogo.avi"
done
