Youtube auto enables "Overlay in-video ads"

But, is there a way to change the ad setings once for all the videos?

Not as just a channel owner. There are no mass claim options for us. Anyone with CMS (content management system) access has tools for this.

I have no way to prove that it is them changing the settings. However, as someone well versed in Adsense, I have never once had YouTube change a setting on me. It seems an odd position for YouTube to start doing that for network partners, but nobody else. heh

A couple years ago, YouTube enabled everybody for the TrueView option (or something like that). I have only been with FS for a few months.

Who knows, maybe I changed the setting. I was going through a lot of my videos and changing settings. I had a lot of videos that I didn't even allow banner ads so I was going back through everything and allowing banner ads. I could have seen that the video had 500K views and enabled video ads not realizing that it was a 1 minute video. Well, I know the setting now so I will keep an eye on it.
