HELP... What are the copyright rules

[Samira]

Hi,

I not sure what the exact rules are to external video footage in my video.

I wanted to add the trailer of an anime in my January favs. video but now I not sure how. There is a youtube that has uploaded the dubbed version of the trailer on youtube. Can I just use that to a extent if I name the source ( so the channel and link) or is there a 30 secound rule like with copyrighted music?
Do I have to ask the channel if I can use it ?
Or can I just use a part of the trailer because the channel that uploaded it doesn't strictly own it himself ?
Can some explain the rules to this I'm not to sure what is allowed

Thank you in advance

If you do not own the content, you must get written permission to use it. If it is transformed(Audio and visual) then it would be treated differently but there is still a risk of a strike that you would have to dispute. You are better off not using anything you do not own.

Oh ok. I might leave it out if there are is no leeway. I don't want a strike it not worth it for a strike
