cleanvid

cleanvid is a little script to mute profanity in video files in a few simple steps:

1. The user provides as input a video file and matching .srt subtitle file. If subtitles are not provided explicitly, they will be extracted from the video file if possible; if not, subliminal is used to attempt to download the best matching .srt file.
2. pysrt is used to parse the .srt file, and each entry is checked against a list of profanity or other words or phrases you'd like muted. Mappings can be provided (eg., map "sh*t" to "poop"), otherwise the word will be replaced with *****.
3. A new "clean" .srt file is created. with only those phrases containing the censored/replaced objectional language.
4. ffmpeg is used to create a cleaned video file. This file contains the original video stream, but the audio stream is muted during the segments containing objectional language. The audio stream is re-encoded as AAC and remultiplexed back together with the video. Optionally, the clean .srt file can be embedded in the cleaned video file as a subtitle track.

You can then use your favorite media player to play the cleaned video file together with the cleaned subtitles.

As an alternative to creating a new video file, cleanvid can create a simple EDL file (see the mplayer or KODI documentation) or a custom JSON definition file for PlexAutoSkip.

cleanvid is part of a family of projects with similar goals:

• 📼 cleanvid for video files (using SRT-formatted subtitles)
• 🎤 monkeyplug for audio and video files (using either Whisper or the Vosk-API for speech recognition)
• 📕 montag for ebooks

Installation

Using pip, to install the latest release from PyPI:

python3 -m pip install -U cleanvid
