• How to modify music pitch in audio of video file and still sound natural

  9 janvier 2020, par Keith Bennett

  I have some karaoke .mp4 video files (legally obtained) for Thai songs, and want to convert the pitch downward to fit my singing range. I’ve gotten most of the way there thanks to https://superuser.com/questions/292833/how-to-change-audio-frequency/1076762#1076762
  using a command line like this :

  ffmpeg -i in.mp4 -af 'asetrate=35280.0,atempo=1.25' out.mp4

  ...but the instruments and human singing voices don’t sound natural at the modified pitch.

  Is there a better way to change the pitch ? I know some commercial products can do this.

  By the way, I wrote a Ruby script to simplify this ffmpeg call ; it’s at https://gist.github.com/keithrbennett/9ba7043792bfb2fcc92d615076a8413f. It enables you to specify a single factor, and modifies both pitch and tempo accordingly.

• FFMPEG -ss 00:22:58 -to 01:37:45 -i input.mkv -c copy output2.mp4 first 2 seconds image is frozen

  15 août 2022, par g3443tdfgdfgdfg

  i'm making clips from an .mkv file using ffmpeg. First i used

  


  ffmpeg -i input.mkv -ss 00:22:58 -to 01:37:45 -c:v copy -c:a copy output.mp4 


  


  but the first 1-2 seconds were only sound without image. Now i'm using the command

  


  ffmpeg -ss 00:22:58 -to 01:37:45  -i 2022_05_26-ABCNews.mkv -c copy output2.mp4 


  


  But even tho the first seconds now have image they still look kind of patchy and frozen, i understand that this might be due to the nature of the .mkv file itself, but i wanted to know if anyone have any command that better perform this function and allow to save those first 1-2 seconds.
