How to use FFMPEG on multiple files | Apply bulk / batch ffmpeg effects on multiple videos
Today, we show how to apply FFMPEG video effects (VFX) on multiple files so that you can take care of hundreds of videos in 1 single batch and 1 single command. So, no more need to spend hours doing tedious work and handling each videos individually: you can now use ffmpeg on multiple files in 1 go. All parameters shown can be of course fully customized to suit your needs. Enjoy!

❶ The following command (as seen in a previous tutorial), converts 1 video file «001.avi» to «001.mp4» (H.264) at 1920x1080 (Full HD), 29.97 frames per second while minimizing conversion loss (crf default is 23):
→ ffmpeg -i 001.avi -crf 17 -ar 48000 -s 1920x1080 -r 29.97 001.mp4
BUT, WHAT IF we now need to apply the same FFMPEG command to 100+ files???
Well, simply use the following batch conversion command at the DOS command (cmd) or "FF prompt":
→ for %f in ("*.avi") do ffmpeg -i "%f" -crf 17 -ar 48000 -s 1920x1080 -r 29.97 "%~nf.mp4"
with:
* %f = Our filename variable
* for %f in ("*.avi") do = For every *.avi files in the ffmpeg.exe folder, …
* ffmpeg -i "%f" -crf 17 -ar 48000 -s 1920x1080 -r 29.97 = … execute the "ffmpeg conversion to .mp4" command seen earlier…
* "%~nf.mp4" = … outputting the result to the same filename with extension .mp4 this time. Note: all files will end up in the same folder
MORE OPTIONS
→ for %f in (“INPUT/*.avi") do ffmpeg -i "%f" -crf 17 -ar 48000 -s 1920x1080 -r 29.97 “%~nf.mp4"
with:
* INPUT/ = Specify input folder for *.avi files (relative path)
→ for %f in (“INPUT/*.avi") do ffmpeg -i "%f" -crf 17 -ar 48000 -s 1920x1080 -r 29.97 “OUTPUT/%~nf.mp4"
with:
* OUTPUT/ = Specify output folder for *.mp4 files (relative path)
→ for %f in ("C:\INPUT\*avi") do ffmpeg -i "%f" -crf 17 -ar 48000 -s 1920x1080 -r 29.97 "C:\OUTPUT\%~nf.mp4"
with:
* C:\INPUT\ = Specify full path to output files
* C:\OUTPUT\ = Specify full path to input files
