Batch trim using FFMPEG

[taonas]

Hi all,

I have aprroximelty 70 mp4's in a folder and they all have a 20 second intro on them

I am looking for the commands to make FFMPEG batch trim the first 20 seconds off each file.
Thanks for any help.

I managed to batch trim all 70 of the files using ffmpeg

the commands i used are;
set ffmpeg="C:\ffmpeg\bin\ffmpeg.exe"
for %f in ("*.mp4") do ffmpeg -i "%f" -ss 00:00:20.000 -c:v copy -c:a copy "trimmed\%f.mp4"

Not certain, but shouldn't a .bat filet have %% instead of a single %.

That script wouldn't work when I tried it. However this one does. Create a folder named "trimmed" first and use correct path to ffmpeg:

for %%a in ("*.mp4") do "C:\FFmbc\ffmpeg" -i %%a -ss 00:00:20.000 -c:v copy -c:a copy trimmed\%%a

I had to update the file with quotes to encapsulate the long file names with spaces. I'm clipping 5 seconds to trim an annoying watermark.

for %%a in ("*.mp4") do C:\ffmpeg\bin\ffmpeg.exe -i "%%a" -ss 00:00:05.000 -c:v copy -c:a copy "trimmed\%%a"
