If let's say I rip out some music files from the base pk3s for a trailer I'm doing, but cite Raven and Lucasarts in the credits, am I still considered infringing copyrights?

If you distribute it to other people, or make it available for other people to view/download- yes.

Thanks. However, most trailers out there do contain music from Jedi Academy one way or another, as well as sounds. It's rare that casual gamers who want to record their games eg. duels, will want to turn off the music. How come that isn't plagiarism?

I just looked through the plagiarism page on jk2files. It says here:

We should make it clear that any music mod that is not integrated into the game will be rejected. This includes mods that have a bunch of music and tell you to use a console command to play them. We are not Napster and Jedi Academy is not a media player. I repeat, these mods will be rejected, so please don't even send them.

In that case, wouldn't trailers be considered being partially "integrated" too?

Just wish to clarify, thanks! :)

This isn't jk2files.

Raven is on the record stating that they don't mind their assets being used in mods made for their games.
