A music video generator based on rhythm
Use it to brainstorm AMVs, montages, and more! Check it out.
Built with moviepy programmatic video editing, and librosa audio analysis.
-
Provide an audio file and a set of video files.
-
Perform rhythm analysis to identify beat locations.
-
Generate a set of random video segments syced to the beat.
-
Discard segments with scene changes, detectable text (e.g. credits), or low contrast (i.e. solid colors, very dark scenes).
-
Combine the segments in order, overlay the audio, and output the resulting music video.
- A Python 3.7+ virtual environment. Using Miniconda is recommended.
Optional:
- Install tesseract >= 3.04 and
pip install tesserocr>=2.2.1for text detection features.
Mugen has not been tested on Windows, but should work provided the dependencies are compiled and installed properly.

Use a series 60% of the time and a movie 40% of the time
mugen create --video-sources Neon_Genesis_Evangelion/ The_End_of_Evangelion.mkv --video-source-weights .6 .4
Slow down scene changes to every other beat
mugen create --events-speed 1/2
Slow down scene changes for leading and trailing weak beats
mugen create --beats-mode weak_beats --group-events-by-type --group-speeds 1/2 1 1/4
Control the speed of scene changes for specific sections
mugen create --group-events-by-slices (0,23) (23,32) (32,95) (160,225) (289,321) (321,415) --group-speeds 1/2 0 1/4 1/2 1/2 1/4
Allow clips with cuts and repeat clips
mugen create --exclude-video-filters not_has_cut not_is_repeat
Use only clips that have text
mugen create --video-filters has_text
mugen preview --audio-source Spazzkid_Goodbye.mp3
Input event locations manually
mugen preview --event-locations 2 4 6 10 11 12
This gets interesting!
mugen preview --audio-events-mode onsets --events-speed 1/2 --events-speed-offset 1
