Script Explanation:
What the script does is that if there's no file named token.pickle it will ask the user to authorize the application and the script will store the user credentials in token.pickle file so that the user doesn't have to authorize the application on every single run and the part 2 of the script changes my YouTube video's title.

Answer 1

Unfortunately, you seem not inclined to make use of the official specification of the Videos.update API endpoint:
The request body of your call to the endpoint needs to specify the video category ID too for to be accepted by the API back-end.
Note that the update_video.py sample code from Google -- that I indicated you at the beginning of your series of posts as valuable source of information -- has all these required things in it.
Again, please acknowledge that you have to absorb (i.e. understand) that code. There's no other way than going through reading carefully the official documentation.
