This can be used to put voices or sounds from a movie or song, an example with summoning, they occupy samples of the BBC transmissions of the Hobbit and the Lord of the Rings (in the songs of the EP Lost Tales) but what I I would like to know if I can use movie or video samples in my songs, whether they are metal or not.

If you mean "legally", unless the source is in the public domain (i.e. there's no copyright on it or there used to be but has expired), you'd have to clear the sample, which means contacting the copyright's owner and paying a fee to use it in your song.
You could get away with it if the sample is treated/processed in such a way that it's unrecognizable.

ok thanks, I just wanted to remove this doubt, to see if we could use them for music hehe, maybe we will record our own samples because we are just starting and we want it to be good, thanks for answering. :3

Some bands here take the risk on demos and things, but usually not on releases that are digitally distributed to YouTube etc. where the copyright owners may be alerted to it.
