Calls the scheduler's `set_timesteps` method and retrieves timesteps from the scheduler after the call. Handles
custom timesteps. Any kwargs will be supplied to `scheduler.set_timesteps`.

Args:
    scheduler (`SchedulerMixin`):
        The scheduler to get timesteps from.
    num_inference_steps (`int`):
        The number of diffusion steps used when generating samples with a pre-trained model. If used, `timesteps`
        must be `None`.
    device (`str` or `torch.device`, *optional*):
        The device to which the timesteps should be moved to. If `None`, the timesteps are not moved.
    timesteps (`list[int]`, *optional*):
        Custom timesteps used to override the timestep spacing strategy of the scheduler. If `timesteps` is passed,
        `num_inference_steps` and `sigmas` must be `None`.
    sigmas (`list[float]`, *optional*):
        Custom sigmas used to override the timestep spacing strategy of the scheduler. If `sigmas` is passed,
        `num_inference_steps` and `timesteps` must be `None`.

Returns:
    `tuple[torch.Tensor, int]`: A tuple where the first element is the timestep schedule from the scheduler and the
    second element is the number of inference steps.
zYOnly one of `timesteps` or `sigmas` can be passed. Please choose one to set custom valuesr-   zThe current scheduler class zx's `set_timesteps` does not support custom timestep schedules.

Pipeline for video-to-video generation using CogVideoX.

This model inherits from [`DiffusionPipeline`]. Check the superclass documentation for the generic methods the
library implements for all the pipelines (such as downloading or saving, running on a particular device, etc.)

Args:
    vae ([`AutoencoderKL`]):
        Variational Auto-Encoder (VAE) Model to encode and decode videos to and from latent representations.
    text_encoder ([`T5EncoderModel`]):
        Frozen text-encoder. CogVideoX uses
        [T5](https://huggingface.co/docs/transformers/model_doc/t5#transformers.T5EncoderModel); specifically the
        [t5-v1_1-xxl](https://huggingface.co/PixArt-alpha/PixArt-alpha/tree/main/t5-v1_1-xxl) variant.
    tokenizer (`T5Tokenizer`):
        Tokenizer of class
        [T5Tokenizer](https://huggingface.co/docs/transformers/model_doc/t5#transformers.T5Tokenizer).
    transformer ([`CogVideoXTransformer3DModel`]):
        A text conditioned `CogVideoXTransformer3DModel` to denoise the encoded video latents.
    scheduler ([`SchedulerMixin`]):
        A scheduler to be used in combination with `transformer` to denoise the encoded video latents.

Encodes the prompt into text encoder hidden states.

Args:
    prompt (`str` or `list[str]`, *optional*):
        prompt to be encoded
    negative_prompt (`str` or `list[str]`, *optional*):
        The prompt or prompts not to guide the image generation. If not defined, one has to pass
        `negative_prompt_embeds` instead. Ignored when not using guidance (i.e., ignored if `guidance_scale` is
        less than `1`).
    do_classifier_free_guidance (`bool`, *optional*, defaults to `True`):
        Whether to use classifier free guidance or not.
    num_videos_per_prompt (`int`, *optional*, defaults to 1):
        Number of videos that should be generated per prompt. torch device to place the resulting embeddings on
    prompt_embeds (`torch.Tensor`, *optional*):
        Pre-generated text embeddings. Can be used to easily tweak text inputs, *e.g.* prompt weighting. If not
        provided, text embeddings will be generated from `prompt` input argument.
    negative_prompt_embeds (`torch.Tensor`, *optional*):
        Pre-generated negative text embeddings. Can be used to easily tweak text inputs, *e.g.* prompt
        weighting. If not provided, negative_prompt_embeds will be generated from `negative_prompt` input
        argument.
    device: (`torch.device`, *optional*):
        torch device
    dtype: (`torch.dtype`, *optional*):
        torch dtype

Function invoked when calling the pipeline for generation.

Args:
    video (`list[PIL.Image.Image]`):
        The input video to condition the generation on. Must be a list of images/frames of the video.
    prompt (`str` or `list[str]`, *optional*):
        The prompt or prompts to guide the image generation. If not defined, one has to pass `prompt_embeds`.
        instead.
    negative_prompt (`str` or `list[str]`, *optional*):
        The prompt or prompts not to guide the image generation. If not defined, one has to pass
        `negative_prompt_embeds` instead. Ignored when not using guidance (i.e., ignored if `guidance_scale` is
        less than `1`).
    height (`int`, *optional*, defaults to self.transformer.config.sample_height * self.vae_scale_factor_spatial):
        The height in pixels of the generated image. This is set to 480 by default for the best results.
    width (`int`, *optional*, defaults to self.transformer.config.sample_height * self.vae_scale_factor_spatial):
        The width in pixels of the generated image. This is set to 720 by default for the best results.
    num_inference_steps (`int`, *optional*, defaults to 50):
        The number of denoising steps. More denoising steps usually lead to a higher quality image at the
        expense of slower inference.
    timesteps (`list[int]`, *optional*):
        Custom timesteps to use for the denoising process with schedulers which support a `timesteps` argument
        in their `set_timesteps` method. If not defined, the default behavior when `num_inference_steps` is
        passed will be used. Must be in descending order.
    strength (`float`, *optional*, defaults to 0.8):
        Higher strength leads to more differences between original video and generated video.
    guidance_scale (`float`, *optional*, defaults to 7.0):
        Guidance scale as defined in [Classifier-Free Diffusion
        Guidance](https://huggingface.co/papers/2207.12598). `guidance_scale` is defined as `w` of equation 2.
        of [Imagen Paper](https://huggingface.co/papers/2205.11487). Guidance scale is enabled by setting
        `guidance_scale > 1`. Higher guidance scale encourages to generate images that are closely linked to
        the text `prompt`, usually at the expense of lower image quality.
    num_videos_per_prompt (`int`, *optional*, defaults to 1):
        The number of videos to generate per prompt.
    generator (`torch.Generator` or `list[torch.Generator]`, *optional*):
        One or a list of [torch generator(s)](https://pytorch.org/docs/stable/generated/torch.Generator.html)
        to make generation deterministic.
    latents (`torch.FloatTensor`, *optional*):
        Pre-generated noisy latents, sampled from a Gaussian distribution, to be used as inputs for image
        generation. Can be used to tweak the same generation with different prompts. If not provided, a latents
        tensor will be generated by sampling using the supplied random `generator`.
    prompt_embeds (`torch.FloatTensor`, *optional*):
        Pre-generated text embeddings. Can be used to easily tweak text inputs, *e.g.* prompt weighting. If not
        provided, text embeddings will be generated from `prompt` input argument.
    negative_prompt_embeds (`torch.FloatTensor`, *optional*):
        Pre-generated negative text embeddings. Can be used to easily tweak text inputs, *e.g.* prompt
        weighting. If not provided, negative_prompt_embeds will be generated from `negative_prompt` input
        argument.
    output_type (`str`, *optional*, defaults to `"pil"`):
        The output format of the generate image. Choose between
        [PIL](https://pillow.readthedocs.io/en/stable/): `PIL.Image.Image` or `np.array`.
    return_dict (`bool`, *optional*, defaults to `True`):
        Whether or not to return a [`~pipelines.stable_diffusion_xl.StableDiffusionXLPipelineOutput`] instead
        of a plain tuple.
    attention_kwargs (`dict`, *optional*):
        A kwargs dictionary that if specified is passed along to the `AttentionProcessor` as defined under
        `self.processor` in
        [diffusers.models.attention_processor](https://github.com/huggingface/diffusers/blob/main/src/diffusers/models/attention_processor.py).
    callback_on_step_end (`Callable`, *optional*):
        A function that calls at the end of each denoising steps during the inference. The function is called
        with the following arguments: `callback_on_step_end(self: DiffusionPipeline, step: int, timestep: int,
        callback_kwargs: Dict)`. `callback_kwargs` will include a list of all tensors as specified by
        `callback_on_step_end_tensor_inputs`.
    callback_on_step_end_tensor_inputs (`list`, *optional*):
        The list of tensor inputs for the `callback_on_step_end` function. The tensors specified in the list
        will be passed as `callback_kwargs` argument. You will only be able to include variables listed in the
        `._callback_tensor_inputs` attribute of your pipeline class.
    max_sequence_length (`int`, defaults to `226`):
        Maximum sequence length in encoded prompt. Must be consistent with
        `self.transformer.config.max_text_seq_length` otherwise may lead to poor results.

Examples:

Returns:
    [`~pipelines.cogvideo.pipeline_output.CogVideoXPipelineOutput`] or `tuple`:
    [`~pipelines.cogvideo.pipeline_output.CogVideoXPipelineOutput`] if `return_dict` is True, otherwise a
    `tuple`. When returning a tuple, the first element is a list with the generated images.
