Visualize piano midi files..
Project description
PianoVis 0.1.5
A Python piano video exporter.
Quick Start
- Install PianoVis:
pip install piano-vis
- Follow this code format:
import pianovis
resolution = (1920, 1080)
fps = 30
offset = 1
vid = pianovis.Video(resolution, fps, offset)
vid.add_midi("midi1.mid")
vid.add_midi("midi2.mid")
vid.set_audio("audio.mp3")
vid.export("video.mp4")
pianovis.Video
pianovis.Video
is the main video class which stores all midi and audio files, and exports the final video.
Video.__init__(resolution: Tuple[int, int], fps: int, offset: int) -> None
- Initializes video.
resolution
: (x, y) pixel resolution of video.fps
: FPS (frames per second) of video.offset
: Offset (frames) of video from audio. Usually, a value of 1 makes the video look lined up with the audio.return
: None
Video.configure(path: str, value: Any) -> None
- Sets an option for the video (read more in the Customization section).
path
: Option path.value
: Value to set path to.return
: None
Video.add_midi(path: str) -> None
- Appends path to midi list.
path
: Midi file path.
Video.set_audio(path: str) -> None
- Sets audio file to path.
path
: Audio file path.
Video.preview(resolution: Tuple[int, int] = (1600, 900), show_meta: bool = True) -> None:
- Opens a pygame window to preview the animation.
resolution
=(1600, 900): Resolution of pygame window.show_meta
=True: Show metadata in the corner of window.
Video.export(self, path: str, multicore: bool = False, max_cores: int = multiprocessing.cpu_count(), notify: bool = False) -> None:
- Exports video to path.
path
: Path to export (mp4)multicore
=False: Use multiple cores to export. Can be faster, but will take more power.max_cores
=multiprocessing.cpu_count(): Maximum cores to use. Only relevant if using multicore.notify
=False: Sends notification when done exporting. Only works on linux.
Customization
Run Video.configure
to change options.
keys.white.gap
: Gap (pixels) between white keys.keys.white.color
: Color (RGB) of white keys.keys.black.width_fac
: Factor of white key width.keys.black.height_fac
: Factor of white key height.keys.black.color
: Color (RGB) of black keys.blocks.speed
: Speed (pixels per second) of blocks.blocks.color_grad
: Color gradient of blocks: ((fac1, hsv1), (fac2, hsv2)...)blocks.rounding
: Rounding radius of blocks.blocks.motion_blur
: Use motion blur in blocks.
