• properly convert Audio 5.1 on PRORES Video to Stereo audio

  26 avril 2021, par user2920456

  I am trying to extract a prores video with just 2.0 (with L R on same track) from a Prores with the below audio track layout. I ran the command below which converted the 5.1 to 2.0 audio/video, but the audio is unusable, dialog is missing when compared to source video. Can you advise how to properly convert the 5.1 audio to stereo.

  


  Desired Output PRORES to contain below track layout

  


  track 0 - video (src Stream #0:0) track 1 - L R (src Stream #0:1)

  


  Command I ran

  


  ffmpeg -i source.mov -ac 2 -c:v copy ouput.mov


  


  Below is the source video/audio Track Layout

  I created a live stream session on instafeed.me then used ffmpeg to send an MP4 file to the stream. But I get IO error.

  


  The command is

  


  ffmpeg -rtbufsize 256M -re -i "1.mp4" -acodec libmp3lame -ar 44100 -b:a 128k -pix_fmt yuv420p -profile:v baseline -s 504x896 -bufsize 6000k -vb 400k -maxrate 1500k -deinterlace -vcodec libx264 -preset veryfast -g 30 -r 30 -f flv "rtmps://live-upload.instagram.com:443/rtmp/XXXXXXX?s_sw=0&s_vt=ig&a=XXXXXXX"
