Here’s a small collection of scripts i’ve made, downloaded, modified, etc to compress, edit, add, remux video files as well as converting mkv files without the need of re-rendering.

Copy the code and save as a .bat file, save it on your ffmpeg bin folder or any command line if ffmpeg was installed with its environment path.

To use the scripts, just drag and drop your video file on the .bat file you created.

Download ffmpeg from here: https://www.gyan.dev/ffmpeg/builds/ffmpeg-release-full.7z

---

In case FFMPEG is missing or the path is not configured, follow these steps.

Download the lastest “static” ffmpeg pack.

Browse in the archive up to the bin subfolder containing ffmpeg, ffprobe and ffplay executables. Uncompress the bin folder (in this example we’ll use C:\ffmpeg\bin)

Register ffmpeg, ffprobe & ffplay to environment variables

Through command lines:
Hit the windows key, write down cmd and press Enter and enter the following command, line after line:

set ffmpeg=C:\ffmpeg\bin
set ffprobe=C:\ffmpeg\bin
set ffplay=C:\ffmpeg\bin

Through user interface:
Go to:

My Computer/Environment variables
Add Name: ffmpeg Value: C:\ffmpeg\bin
Add Name: ffprobe Value: C:\ffmpeg\bin
Add Name: ffplay Value: C:\ffmpeg\bin
