Simple and fast library to convert midi files to video

Midi2Vid - Simple and Fast Midi to Video Converter

Midi to video converter. This program renders the notes of a midi file to a video. The renderer is built on top of the pygame library and uses multiple processes to generate the frames of the video. It then uses ffmpeg to convert the frames to a video. It also uses the fluidsynth library to render the midi file to a wav file.

Installation

Install from github using pip:

pip install git+https://github.com/pianoviz/midi2vid.git

Build with docker:

docker build -t midi2vid-base .
docker run --rm -v $(pwd):/app midi2vid-base -i data/example.mid -o your_output.mp4

Build from source:

git clone https://github.com/pianoviz/midi2vid.git
cd midi2vid
pip install -e .

Usage

midi2vid -i <input_midi_file> -o <output_video_file>

Options

-i, --input: Input midi file
-o, --output: Output video file
--config: Path to the configuration file (default: config/default.json)

Configuration

The configuration file is a JSON file that specifies various parameters for the video generation. Here is an example configuration file:

{
  "soundfont_path": "data/soundfont.sf2",
  "max_note_length": 50,
  "n_processors": 4,
  "screen_width": 1920,
  "screen_height": 1080,
  "bpm": 120,
  "fps": 30,
  "speed": 200,
  "white_note_color": [255, 255, 255],
  "black_note_color": [49, 49, 49],
  "background_color": [43, 43, 43],
  "octave_lines_color": [92, 92, 92],
  "note_color": [179, 44, 49],
  "dark_note_color": [113, 34, 36],
  "right_note_color": [168, 255, 145],
  "left_note_color": [176, 202, 229],
  "dark_right_note_color": [118, 208, 68],
  "dark_left_note_color": [124, 142, 151],
  "estimate_hands": false
}

The estimate_hands parameter is experimental and is used to estimate the hand positions based on the notes played. It is currently under development and may not work as expected.

Example

There is an example midi file in the data directory. You can run the following command to generate a video from the example midi file:

midi2vid -i data/example.mid -o example.mp4
