• ffmpeg - Input link in1:v0 parameters (size 640x640, SAR 16:9) do not match the corresponding output link in0:v0 parameters (640x640, SAR 427:240)

  19 mai 2016, par fobus

  I’m trying to concat 4 mp4 files. I’m using the command below but not able to concat

  ffmpeg -i new1.mp4 -i new2.mp4 -i new3.mp4 -i new4.mp4 -filter_complex concat=n=4:v=1:a=1 output.mp4

  Getting this error :

  Input link in1:v0 parameters (size 640x640, SAR 16:9) do not match the corresponding output link in0:v0 parameters (640x640, SAR 427:240)

  All four vides has the same codec and same size (640x640) and the same bitrate (30)

  What I am doing wrong ?

• FFMPEG recode clip1 to match clip2 for concat demux

  21 novembre 2020, par Gert Gottschalk

  I want to concat two video clips using ffmpeg concat. To use concat demuxer both should have same codec settings. clip2 is much shorter so I want to recode it to match clip1. Initially clip2 had tbn not matching and I adjusted that with '-video_track_timescale 50000'. Still the concat video after the cut into clip2 is garbled (audio seems OK)

  


  This is what ffprobe tells for clip1 :

  Then for concat :

  


  /home/tools/bin/ffmpeg -f concat -i list.files  -y clip12.mp4


  


  The only gap is with
clip1 : 2080 kb/s
clip2 : 1553 kb/s

  


  Is that significant ?

  


  If yes, how to recode clip2 to match and result in concat clip12 being clean ?

  


  EDIT (Per feedback from llogan) :

  


  Probing input clips with latest ffprobe.

  Probably need to match audio channel. I noticed that the concat too a long time. I was expecting the concat to just do copying and not re-rendering.
