I'm trying to use the ffprobe and bash loop script to subtract from the length of the video last 10sec. But it writes me a syntax error. Any ideas?
for f in *.mp4; do \
videoduration=$(ffprobe -i $f -show_entries format=duration -sexagesimal -v quiet -of csv="p=0"); \
cutduration=00:00:10.000000; \
duration=$((videoduration - cutduration)); \
echo "$duration"; done
