[Q?] Videos that can be monetized?

So I was under the impression you could NOT monetize video game videos.

Yet I see channels with that. Is it not copyrighted? Like, I wouldn't be able to monetize videos of for example film previews of the 90s.

I get denied monetization for videos for using a short old video reference.

Is there any actual place where they explain what do's or don'ts when it comes to what you can actually can monetize.

I am starting to get kinda confused...Every time I think I got it figured out, something is there to mess with me ....

If the video is short then it is fine, I.e like 4 minutes. However if it is longer then it needs to have something like commentary that is instructional.

Otherwise it is just a video of a computer game and the content isn't really the uploader's to monetize. YouTube have pages explaining this now on there partner help section.

You can monetize allmost every type of video on youtube if you know how...
