Avidemux is great for simple video editing jobs. I often use it to extract clips from longer videos while retaining their native encoding, or to convert videos from one format to another.
Today I learned something really useful and wanted to write up a post about it.
Batch processing multiple videos
Step 1. Get one video exported the way you want it, then save the settings as a
Project file (File > Project script > Save as project).
Step 2. Edit the
.py file and remove the following lines that are specific to the source video:
adm.loadVideo adm.clearSegments adm.addSegment adm.markerA adm.markerB
Step 3. Write a script to process the video file(s).
Linux (Bash script)
This script processes one video at a time.
avidemux3_cli --load [source-file.vob] --run [project-settings.py] --save [output-file.mkv] --quit
Windows (batch file)
This script will run on all MP4, MOV, and MTS files in the current folder.
set avidemux="C:\[path-to-Avidemux]\Avidemux.exe" : %%~nf returns the filename without the extension for %%f in (*.mp4 *.mov *.mts) do ( %avidemux% --load "%%f" --run settings.py --save "%%~nf.mkv" --quit )
