youtube-comment-downloader --url https://www.youtube.com/watch?v=ScMzIvxBSi4

or using a custom filename and/or format (e.g., CSV):

youtube-comment-downloader --youtubeid ScMzIvxBSi4 --output comments.csv --format csv

For Youtube IDs starting with - (dash) you will need to run the script with: -y=idwithdash or --youtubeid=idwithdash

Usage as library

You can also use this script as a library. For instance, if you want to print out the 10 most popular comments for a particular Youtube video you can do the following:

from itertools import islice
from youtube_comment_downloader import *
downloader = YoutubeCommentDownloader()
comments = downloader.get_comments_from_url('https://www.youtube.com/watch?v=ScMzIvxBSi4', sort_by=SORT_BY_POPULAR)
for comment in islice(comments, 10):
    print(comment)
