1.9. Movie

You can easily generate a movie from a set of frames by using the torchmfbd.gen_movie function. The function takes as input the frames and, optionally, another set of frames, and generates a movie with the frames and the warped frames side by side. The function uses the matplotlib library to generate the movie. The function returns the movie as a file, either in mp4 or gif format.

torchmfbd.gen_movie(frames, warped, fps=8, filename='movie.mp4')

The function has the following options:

• frames: tensor

  Tensor of shape (n_frames, n_x, n_y) with the frames to be shown in the movie.

• warped: tensor, optional

  Tensor of shape (n_frames, n_x, n_y) with the warped frames to be shown in the movie. Default is None.

• fps: int, optional

  Frames per second of the movie. Default is 1.

• filename: str, optional

  Name of the file to save the movie. Default is ‘movie.gif’.

• deltat: int, optional

  Time interval between frames in milliseconds. Default is 300.
