• How to split multiple videos 2.24 seconds before the end

  15 décembre 2019, par Leendert

  I have a folder with 100 videos, I need to split all videos into 2, the split needs to happen 2 seconds before the end of every video.

  I want to keep both parts of the video after the split.

  So far I have the code below, this will trim 2 seconds from the end of every video that is in de same folder as the .bat file.
  It will put the new videos inside of a folder called ’new files’.
  The problem is that the length of the video is not trimmed. Only audio and video. So the last 2 seconds will just be the last frame and no audio.

  for %%a in ("*.mp4") do ffmpeg -i "%%a" -filter_complex "[0]trim=2,setpts=PTS-STARTPTS[b];[b][0]overlay=shortest=1" -shortest -c:a copy "newfiles\%%~na.mp4" pause 

• Split single video input files into 30 second blocks

  6 juin 2016, par Ycon

  I am trying to split several video files (.mov) into 30 second blocks.

  I do not need to specify where the 30 seconds start or finish.

  EXAMPLE- A single 45 second video (VID1.mov) will be split into VID1_part1.mov (30 seconds), VID1_part2.mov (15 seconds). Ideally, I can remove audio too.

  I made an attempt, using bash (osx), but was unsuccessful. It did not split the video into multiple parts- instead it just seemed to modify the original file (and made it into a length of 1-2 seconds) :

  find . -name '*.mov' -exec ffmpeg -t 30 -i \{\} -c copy \{\} \;

• Split audio files using silence detection

  30 juillet 2024, par beero

  I've more than 200 MP3 files and I need to split each one of them by using silence detection. I tried Audacity and WavePad but they do not have batch processes and it's very slow to make them one by one.

  



  The scenario is as follows :

  



  

  • split track whereas silence 2 seconds or more

  


  • then add 0.5 s at the start and the end of these tracks and save them as .mp3

  


  • BitRate 192 stereo

  


  • normalize volume to be sure that all files are the same volume and quality

  


  



  I tried FFmpeg but no success.
