A 10 second clip of a movie isn’t necessarily fair use; It’s decided on a case by case basis. You can use as much as you need to get your point across; No more. If that’s 10 seconds, you can use 10 seconds. If that’s a minute, you can use a minute.
But if Google's lawyers took a stance on this, they could use precedent to set defined rules for what actually counts as fair use and all these claimants would be fucked.
