  • FFmpeg destroys my Images

  I want to create a video file that is made from all of my Images. I have found my command to do so ffmpeg -framerate 25 -i *.jpg -c:v libx264 -profile:v high -crf 20 -pix_fmt yuv420p output.mp4
  but I have a really large collection of images so the terminal is hitting me with "bash : /usr/bin/ffmpeg : Argument list too long" . How can I bypass this ?

• Batch reduce bitrate and size of mp3 audio files with ffmpeg

  18 novembre 2016, par Wes Modes

  I was looking for a way to batch reduce mp3 bitrate on my sizable collection of mp3 files. It was surprising difficult given that this must be a super common thing to want to do.

  In fact, there are dozens, maybe hundreds, of posts from people asking how to do it, and dozens of utilities available for varying amounts of money that claim to do just that. Looking around and trying some of the free software, I was surprised that none made the task of batch converting/adjustment easy.

  If I wanted to convert a single file, I’m told this is a decent way to do it :

  ffmpeg -y -loglevel "error" -i "my_music_file.mp3" -acodec libmp3lame  -ab $BITRATE "my_music_file_new.mp3"

  (Though I’d prefer if the file was changed in place and resulted in the same name.)

  I need a simple bash script using ffmpeg that will recursively go through my music directory and change the bitrate of my mp3 files.
