Invoking resize filter from the command line for batch usage

[apache]

I've been attempting to figure out how to do a batch resize for all of the files in a folder to a certain size in the Windows environment and I haven't been able to find anything that would let me do the entire directory in a batch.  Is there an easy way to define the video resize filter as a filter set to be called from the command line?

probably:
load video, set codecs: audio and video, apply the resize video. Now from Main Menu: File: Tinypy Project: Save as Project.
You should end up with a file givenname.py. Edit this file and delete reference to loaded video and markers.
Save this project file. This project file can now be used from command line.
More details can be found here: 2.6 audio track switching in job.py
If this would not work with avidemux_cli.exe try with avidemux.exe. (GUI) Check the program names for exact name, don't have windows.

so would a py file with these contents work for that?

With a batch file like this:

set avidemux="D:\Program Files\Avidemux 2.6\avidemux_cli.exe"
set videocodec=FFmpeg4
set audiocodec=COPY
set container=MP4
set output=MP4

You're setting codecs in the project file, would not need to set these in batch file:

Code Select Expand


set avidemux="D:\Program Files\Avidemux 2.6\avidemux_cli.exe"
for %%f in (*.mp4) do %avidemux% --load "%%f" --run "c:\test3.py --save "%%f.s.mp4" --quit 

test3.py is best referenced to its path where it is.
