  • Videos processed with ffmpeg are not 1080p as specified by flags

    2 septembre 2012, par ensnare

    I'm converting videos in Python using ffmpeg + libx264.

    I've noticed that when I use the below code, the output width and height are not consistent. All input files are 1080p, but the output files are sometimes 1080p, and other times twice the size or somewhere inbetween.

    This is the 2-pass code I am using to generate my videos.

      #Generate 1080p Movie
    
  if not os.path.exists(destination_filename_1080):
    
    pass_num = 1
    
    while pass_num <= 2:
    
      p = subprocess.Popen(['ffmpeg','-i', str(filename),
    
                            '-acodec' , 'aac' ,
    
                            '-ab' , '192k' ,
    
                            '-ac' , '2' ,
    
                            '-vcodec' , 'libx264' ,
    
                            '-strict' , '-2' ,
    
                            '-vpre' , 'ipod640' ,
    
                            '-threads' , '8' ,
    
                            '-s' , '1920x1080' ,
    
                            '-b:v' , '10M' ,
    
                            '-pass' , str(pass_num) ,
    
                            '-passlogfile' , random_1080 ,
    
                            '-y' ,
    
                            destination_filename_1080_temp])
    
      p.wait()
    
      pass_num = pass_num + 1

    It's my understanding that the "-s 1920x1080" flag should force the output to be 1080p, no ? I'm not sure how the output size can be greater than 1080p when the input is only 1080p.

    Thanks in advance.

  • Why is only one of multiple overlayed videos playing in FFmpeg ? [closed]

    27 mai 2023, par Sixtus Anyanwu

    Only one out of multiple overlayed videos is playing FFmpeg

    


    I am trying to overlay 2 playable videos on top of another video in ffmpeg.

    


    ffmpeg -hide_banner -i finalagain.mp4 -i Tatsumaki0trim.mp4 -i Tatsumaki1trim.mp4 -filter_complex "[0][1]overlay=x=(W-w)/2:y=(H-h)/2:enable='between(t,4,8)'[v1]; [v1][2]overlay=x=(W-w)/2:y=(H-h)/2:enable='between(t,0,4)'[v2]" -map "[v2]" -map 0:a -preset ultrafast trial.mp4

    


    But the 1st video gets played while the second remain static.
Here is the video on YouTube.
