"""Use this method to send video files.

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".

For a contact that exists in your Telegram address book you can use his phone number (str).

video (``str``):

Video to send.

Pass a file_id as string to send a video that exists on the Telegram servers,

pass an HTTP URL as a string for Telegram to get a video from the Internet, or

pass a file path as string to upload a new video that exists on your local machine.

caption (``str``, *optional*):

Video caption, 0-1024 characters.

parse_mode (``str``, *optional*):

Pass "markdown" or "html" if you want Telegram apps to show bold, italic, fixed-width text or inline

URLs in your caption. Defaults to "markdown".

duration (``int``, *optional*):

Duration of sent video in seconds.

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

Video width.

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

Video height.

thumb (``str``, *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.

supports_streaming (``bool``, *optional*):

Pass True, if the uploaded video is suitable for streaming.

disable_notification (``bool``, *optional*):

Sends the message silently.

Users will receive a notification with no sound.

reply_to_message_id (``int``, *optional*):

If the message is a reply, ID of the original message.

reply_markup (:obj:`InlineKeyboardMarkup` | :obj:`ReplyKeyboardMarkup` | :obj:`ReplyKeyboardRemove` | :obj:`ForceReply`, *optional*):

Additional interface options. An object for an inline keyboard, custom reply keyboard,

instructions to remove reply keyboard or to force a reply from the user.

progress (``callable``, *optional*):

Pass a callback function to view the upload progress.

The function must take *(client, current, total, \*args)* as positional arguments (look at the section

below for a detailed description).

progress_args (``tuple``, *optional*):

Extra custom arguments for the progress callback function. Useful, for example, if you want to pass

a chat_id and a message_id in order to edit a message with the updated progress.

Other Parameters:

client (:obj:`Client`):

The Client itself, useful when you want to call other API methods inside the callback function.

current (``int``):

The amount of bytes uploaded so far.

total (``int``):

The size of the file.

*args (``tuple``, *optional*):

Extra custom arguments as defined in the *progress_args* parameter.

You can either keep *\*args* or add every single extra argument in your function signature.

Returns:

:obj:`Message`: On success, the sent video message is returned.

``None`` -- In case the upload is deliberately stopped with :meth:`stop_transmission`.

Raises:

RPCError: In case of a Telegram RPC error.
