How do I download videos from Pexels API?

I have this code that can pull images off of Pexels, but I don't know how to change it to video. I haven't seen anyone do this before and any help greatly appreciated. I tried switching all the photo tags to videos but that seemed not to work. I've also tried adding more libraries but that doesn't seem to work either.

import argparse
import json
import os
import time

import requests
import tqdm
from pexels_api import API

PEXELS_API_KEY = os.environ['PEXELS_KEY']
MAX_IMAGES_PER_QUERY = 100
RESULTS_PER_PAGE = 10
PAGE_LIMIT = MAX_IMAGES_PER_QUERY / RESULTS_PER_PAGE


def get_sleep(t):
    def sleep():
        time.sleep(t)
    return sleep


def main(args):
    sleep = get_sleep(args.sleep)

    api = API(PEXELS_API_KEY)
    query = args.query

    page = 1
    counter = 0

    photos_dict = {}

    # Step 1: Getting urls and meta information
    while page <= PAGE_LIMIT:
        api.search(query, page=page, results_per_page=RESULTS_PER_PAGE)
        photos = api.get_entries()

        for photo in tqdm.tqdm(photos):
            photos_dict[photo.id] = vars(photo)['_Photo__photo']
            counter += 1

        if not api.has_next_page:
            break

        page += 1
        sleep()

    print(f"Finishing at page: {page}")
    print(f"Images were processed: {counter}")

    # Step 2: Downloading
    if photos_dict:
        os.makedirs(args.path, exist_ok=True)

        # Saving dict
        with open(os.path.join(args.path, f'{query}.json'), 'w') as fout:
            json.dump(photos_dict, fout)

        for val in tqdm.tqdm(photos_dict.values()):
            url = val['src'][args.resolution]
            fname = os.path.basename(val['src']['original'])
            image_path = os.path.join(args.path, fname)

            if not os.path.isfile(image_path):  # ignore if already downloaded
                response = requests.get(url, stream=True)

                with open(image_path, 'wb') as outfile:
                    outfile.write(response.content)
            else:
                print(f"File exists: {image_path}")
