vidfilter_scripter

An mpv front-end which creates a mencoder script with video adjustments. The script reencodes your video with the correct adjustments using ffmpeg.

Installation

You must have libmpv-dev and ffmpeg installed on your computer. On a debian based system using apt, run the following:

$ sudo apt install libmpv-dev ffmpeg

Install vidfilter_scripter using pip:

pip install vidfilter_scripter

Usage

Preview the video you wish to reencode, adjusting brightness, contrast, hue, saturation, and gamma:

When you are satisfied, click the "Create script" button. The created menocoder script will be shown with a "Save as" function available to save it to disk.

Save the script and run it. You can run a script in the background using "at":

$ realpath reencode.sh | at now

...or...

$ realpath reencode.sh | batch

Or if you have more than one computer, you run it on the one in the closet at night!

$ realpath reencode.sh | at midnight

Custom script

You can always change the script before running it.

I chose some decent encoding options for one of several common video heights. You can replace those lines with your own preferece, if you want.

The purpose of this "program" is not to be a complete reeencoder. It is to be able to preview the video filter settings as you modify them, and then generate a correct video filter option to pass to ffmpeg for reencoding.
