What YouTube settings can I set?
A YouTube upload needs a title of up to 100 characters, and Socialync builds one from your caption when you leave the title empty. You can also set a description of up to 5,000 characters, tags, a category, a made for kids flag, and whether the video is public or private. Videos that are not Shorts can take a custom thumbnail, and if it cannot be attached the video goes out with the thumbnail YouTube picks.

The AI label
If a video is AI-generated, the composer switch for the AI label turns on YouTube's "Altered or synthetic content" disclosure for you. See the article on the AI-generated label for the other platforms.
