FFMpeg Tool

SUMMARY

• The goal of this application is to explain how to get FFmpeg 64-bit (or 32-bit) Static and how to use it

HOW TO GET FFMPEG STATIC 64/32 bits

• Once ffmpeg is installed on your PC, it permits to manipulate video and apply some action on it (video split, changing metadata, and many others functions...).
• FFMpeg static build for Windows is a binary .exe available for download on https://ffmpeg.zeranoe.com/builds/
  • You have to choose between 32 and 64 bits (depending on your PC Windows OS configuration)
    • Example of archive name for 64 bits : ffmpeg-20160418-git-13406b6-win64-static.7z
• Once downloaded on your PC, extract the archive with 7zip software in a local directory of your PC.
• Install then one of the script below in the directory where is situated the FFmpeg binary (bin/ffmpeg.exe). In case no script is available for download, create a file .bat and copy the command line in it.
• The scripts are given as examples. You have to edit and modify them to match your needs (for example: video name)
• Finally, double click on .bat to execute your script
• The list of ffmpeg functions is very huge. Please refer to ffmpeg official site for more information
• Innes can not be responsible of video degradation in case wrong using of these scripts
