Quick answer
A private YouTube video cannot be downloaded by SnapLoad. Only public or freely accessible links can be processed.
On YouTube, visibility status changes everything. A private video does not expose the same public information as a standard or unlisted video.
Private, unlisted or public
A public video is visible to everyone. An unlisted video can sometimes work if you have the full URL. A private video requires account permissions the site does not have.
- Public: can be supported.
- Unlisted: can sometimes work if the URL is openly accessible.
- Private: not supported.
Why the download is blocked
When YouTube hides the media behind account permissions or authentication, there is no reliable public stream to use.
- Check the video visibility status.
- Test the URL in a browser where you are not logged in.
