        .. include:: /_includes/usable-by/users.rst

        Parameters:
            chat_id (``int`` | ``str``):
                Unique identifier (int) or username (str) of the target chat.
                For your personal cloud (Saved Messages) you can simply use "me" or "self".

            story_id (``int``):
                Story identifier in the chat specified in chat_id.

            media (``str`` | ``BinaryIO``, *optional*):
                Video or photo to send.
                Pass a file_id as string to send a animation that exists on the Telegram servers,
                pass a file path as string to upload a new animation that exists on your local machine, or
                pass a binary file-like object with its attribute ".name" set for in-memory uploads.

            duration (``int``, *optional*):
                Duration of sent video in seconds.

            width (``int``, *optional*):
                Video width.

            height (``int``, *optional*):
                Video height.

            thumb (``str`` | ``BinaryIO``, *optional*):
                Thumbnail of the video sent.
                The thumbnail should be in JPEG format and less than 200 KB in size.
                A thumbnail's width and height should not exceed 320 pixels.
                Thumbnails can't be reused and can be only uploaded as a new file.

            progress (``Callable``, *optional*):
                Pass a callback function to view the file transmission progress.
                The function must take *(current, total)* as positional arguments (look at Other Parameters below for a
                detailed description) and will be called back each time a new file chunk has been successfully
                transmitted.

            progress_args (``tuple``, *optional*):
                Extra custom arguments for the progress callback function.
                You can pass anything you need to be available in the progress callback scope; for example, a Message
                object or a Client instance in order to edit the message with the updated progress status.

        Returns:
            :obj:`~pyrogram.types.Story`: On success, the edited story is returned.
