• ffmpeg conversion executable file output ".MOD : no files in such directory"

  11 octobre 2023, par Zezaps

  I installed ffmpeg using Homebrew in macOS 12.2. I have a folder of MOD files from an old camera that I need to convert to MOV or MP4 to edit them, I have a .bat file in my Windows machine that I can run on a folder that has MOD files to batch convert them to MP4 or MOV that I can easily tweak but I'm kinda clueless with how to do this on my new (and first) Mac, I came across this script that I managed to use once through the terminal but tried putting it in a executable file so I can easily run it and copy it in every folder that I need to for new projects. When I created the exec file I'm not sure if I did it correctly though.

  


  for i in *.MOD;
  do name=`echo "$i" | cut -d'.' -f1`
  echo "$name"
  ffmpeg -i "$i" "${name}.MOV"
done


  


  This script is inside an exec file that I edited using TextEdit, it works sometimes if I go to the directory through the terminal and run it but if I run it double clicking it I get a ".MOD : Not such file or directory" even though I placed the exec on a folder that has multiple .MOD files.

  


  Here is the full terminal output

• FFMPEG disabled automatic compression file

  2 novembre 2017, par HenrykVIII

  How to disable FFMPEG in its own compressed file compression, which does not come from the program code. This is when the file is merged (as the first task) or file stabilization (as the first task). I lose on file quality by reducing itself from 16k to 7k birate files (in parts) input.

  So, without loss, I have to merge files or stabilize them so that they do not change ?

  I will add that the effect does not affect every film - only the majority. None of which come out of a duel completely and eg for 16.2k input birate have output 16k birate .. What is no visible loss.

  But the loss from 16k to 7k is already visible on the details and especially the movies shot at night and in the wrong light.

  I enclose the wrapper code c # :
   
  The same situation occurs when the first task is to combine files :

  Can anyone help ?? : (((
