• FFMPEG concatenate multiply files with various extensions and properties

  28 juillet 2022, par KRUK

  I'm trying to create a movie on Windows using ffmpeg from files that are from different devices and in different extensions (.mp4, .mov). Is there any way to combine any file extensions into one final movie that will play properly ?

  


  I'm thinking of such an approach, to first normalize all files to the same format (What is the recommended final format ?) and only then combine them into a final file.

  


  I am experimenting with this approach :

  


  ffmpeg -i [input.anyFormatX] outputX.mp4


  


  and then

  


  ffmpeg -f concat -i [List of files] output.mp4


  


  But unfortunately this does not work for all files, should pay attention to the codecs or maybe some other intermediate format ? The biggest problem appears with files recorded with Iphone and in extension .mov. After the first stage, these videos look overburnt, as if they have a lot of raised brightness, how to correct this ?

  


  Do you know perhaps any generic solution, which would allow the assembly of videos from different devices (including Iphone) and with different parameters such as frame rate or resolution ?

• 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.
