videoclip

Easily create video and audio clips with mpv in a few keypresses. Videoclips are saved as .mp4 or .webm. Subtitles can be embedded into the clips.

Prerequisites

Install mpv.
Add the directory where mpv is installed to the PATH.

If you're using GNU/Linux, this step is likely unnecessary because package managers (apt, pacman, etc.) place executable files to /usr/bin which is already added to the PATH. If you have installed mpv to a non-standard location, or if you're not using the GNU operating system, you need to make sure that mpv is added to the PATH.

Installation

Using git

Clone the repository to the mpv/scripts directory. The command below works on the GNU operating system with git installed.

git clone 'https://github.com/Ajatt-Tools/videoclip.git' ~/.config/mpv/scripts/videoclip

To update the user-script on demand later, you can execute:

cd ~/.config/mpv/scripts/videoclip && git pull

Manually

Download the repository and extract the folder containing videoclip.lua to your mpv scripts directory:

OS	Location
GNU/Linux	`~/.config/mpv/scripts/`
Windows	`C:/Users/Username/AppData/Roaming/mpv/scripts/`

Note: in Celluloid user scripts are installed by switching to the "Plugins" tab in the preferences dialog and dropping the files there.

Expected directory tree

~/.config/mpv/scripts
|-- other_addon_1
|-- other_addon_2
`-- videoclip
    |-- main.lua
    |-- ...
    `-- videoclip.lua

Configuration

The config file should be created by the user, if needed.

OS	Config location
GNU/Linux	`~/.config/mpv/script-opts/videoclip.conf`
Windows	`C:/Users/Username/AppData/Roaming/mpv/script-opts/videoclip.conf`

If a parameter is not specified in the config file, the default value will be used. mpv doesn't tolerate spaces before and after =.

Example configuration file:

# Absolute paths to the folders where generated clips will be placed.
# `~` or `$HOME` are not supported due to mpv limitations.
video_folder_path=/home/user/Videos
audio_folder_path=/home/user/Music

# Opus sounds good at low bitrates 32-64k, but aac requires 128-256k.
audio_bitrate=32k

# Catbox.moe upload settings
# Whether uploads should go to litterbox instead of catbox.
# catbox files are stored permanently, while litterbox is temporary

litterbox_expire=72h

Key bindings

OS	Config location
GNU/Linux	`~/.config/mpv/input.conf`
Windows	`C:/Users/Username/AppData/Roaming/mpv/input.conf`

Add this line if you want to change the key that opens the script's menu.

c script-binding videoclip-menu-open

Usage

Open a file in mpv and press c to open the script menu.
Follow the onscreen instructions. You need to set the start point, end point, and then press c to create the clip.

It is possible to create silent videoclips. To do that, first mute audio in mpv. The default key binding is m.

If a video has visible subtitles, they will be embedded automatically. Toggle them off in mpv if you don't want any subtitles to be visible. The default key binding is v.
