There are some instructions regarding the lecture "Creating a YouTube Subtitle Summary Service".
It seems that YouTube has currently blocked the method of extracting subtitles without an API.
So, since the method provided in the current lecture is no longer valid, I will provide an alternative using the official YouTube method below.
Use the official YouTube API. (Free - but there is a daily quota limit. Quota means a set number of calls per day.)
The official API is a bit complicated, so you may need to follow it step by step.
thank you
Data Popcorn Dream.
(Updated 2025-06-22) I uploaded a video on how to do it with Apify (API Marketplace Platform) on YouTube. If you have difficulty with the official API, watch this video and follow along!
