Background: I'm preparing research about a music-based arcade game, playable in the arcade game center. Requiring video dataset (including music in it), I recorded videos from the game playing by myself.
Question: Is it legal to use the videos for publishing an academic paper, even though they are just a kind of replay-videos?
Like many published research about games (e.g., Super Mario, League of Legend, ...), it seems to be possible to use in-game contents for research. I know there is a copyright issue especially using audio data for commercial use, but I'm wondering if it is still an issue in terms of academic research.
Actually, I don't know where to start searching keywords about this.
