Anyone from here is a ffmpeg expert?
 

Hello,

I need a help from a ffmpeg expert. I want the ffmpeg to start encoding after 20 seconds of video. So basically to cut the start of the video. Any of you knows to command I have to add in ffmpeg command line?

Thanks and waiting for your answers

I know that site, but practicaly that makes image frames. I need to cut the first 20 seconds of the movie.

-ss is just the start time, so -ss 20 will start your encode 20 seconds in.

$ffmpeg_command = "-acodec libfaac -ss 25 -keyint_min 20 -r 20 -vcodec libx264 -crf 22 -b 1000k -bt 1000k -y -v 0 -bf 16 -threads 0"; //settings for ffmpeg encoding

I added but is not starting the encode in 20 seconds

i use this in a bat file on pc:
md new
for %%a in ("*mp4") do ffmpeg -ss 20 -t 20 -i "%%a" -vcodec copy -movflags faststart -acodec copy "new\%%~na.mp4"
pause

You have -ss 25 in that command string, so the encoding should start 25 seconds in using that.

.

Should start but is not starting. Starts from 0
