# Video Processor

The `VideoProcessor` provides a unified API for video pipelines to prepare inputs for VAE encoding and post-processing outputs once they're decoded. The class inherits `VaeImageProcessor` so it includes transformations such as resizing, normalization, and conversion between PIL Image, PyTorch, and NumPy arrays.

  The input video. It can be one of the following:
  * List of the PIL images.
  * List of list of PIL images.
  * 4D Torch tensors (expected shape for each tensor `(num_frames, num_channels, height, width)`).
  * 4D NumPy arrays (expected shape for each array `(num_frames, height, width, num_channels)`).
  * List of 4D Torch tensors (expected shape for each tensor `(num_frames, num_channels, height,
    width)`).
  * List of 4D NumPy arrays (expected shape for each array `(num_frames, height, width, num_channels)`).
  * 5D NumPy arrays: expected shape for each array `(batch_size, num_frames, height, width,
    num_channels)`.
  * 5D Torch tensors: expected shape for each array `(batch_size, num_frames, num_channels, height,
    width)`.
- **height** (`int`, *optional*, defaults to `None`) --
  The height in preprocessed frames of the video. If `None`, will use the `get_default_height_width()` to
  get default height.
- **width** (`int`, *optional*`, defaults to `None`) --
  The width in preprocessed frames of the video. If `None`, will use get_default_height_width()` to get
  the default width.</paramsdesc><paramgroups>0</paramgroups></docstring>

Preprocesses input video(s).
