Video

Format a video for logging to W&B.

Video(
    data_or_path: Union['np.ndarray', str, 'TextIO', 'BytesIO'],
    caption: Optional[str] = None,
    fps: Optional[int] = None,
    format: Optional[str] = None
)

Args
data_or_path	(numpy array, string, io) Video can be initialized with a path to a file or an io object. The format must be "gif", "mp4", "webm" or "ogg". The format must be specified with the format argument. Video can be initialized with a numpy tensor. The numpy tensor must be either 4 dimensional or 5 dimensional. Channels should be (time, channel, height, width) or (batch, time, channel, height width)
caption	(string) caption associated with the video for display
fps	(int) The frame rate to use when encoding raw video frames. Default value is 4. This parameter has no effect when data_or_path is a string, or bytes.
format	(string) format of video, necessary if initializing with path or io object.

Examples:

Log a numpy array as a video

import numpy as np
import wandb

wandb.init()
# axes are (time, channel, height, width)
frames = np.random.randint(low=0, high=256, size=(10, 3, 100, 100), dtype=np.uint8)
wandb.log({"video": wandb.Video(frames, fps=4)})
