ved
A video-editing API for automation
Ved is a video-editing framework that allows for algorithmic video-editing, whether it be automation of repetitive tasks, advanced integration with machine-learning or just writing that filter that no video editor supports.
Note that this project isn't ready to be used yet. If you would like to contribute, please check out CONTRIBUTING!
Usage
Load a video and export it at a different framerate:
video = VideoFile('input.mp4')
movie = Movie(video.width, video.height, [video])
movie.record('output.mp4', framerate=24)Blur an image:
image = ImageFile('input.png') # create an image node
blur = GaussianBlur(image, 3.0) # create a blur node
movie = Movie(image.width, image.height, [image, blur]) # add them both to the video
movie.screenshot('output.png', time=0.0)As you might have noticed, everything in Ved is either a movie or a node. A movie is built up of nodes, which can be used for anything.
Create a custom node:
class Sine(Audio): # extend the base audio node
def __init__(self, frequency):
self.frequency = frequency
def __call__(self):
# Store the audio sample in `self.sample`, a special property read by the movie
# The Audio class exposes a `sample_rate` property
self.sample = Math.sin(self.sample_rate / float(self.frequency))
sine = Sine(800)
movie = Movie(1, 1)
movie.nodes = [sine] # same as passing nodes to the movie's constructor
movie.record('output.wav')Contributing
