not a gamer, so just providing a newbie response in case it helps
Do you have the video clips local to OBS (ie not out on Internet somewhere)?
If so, you can add Media Source (s), and there you go.... but if you want latest video files (clips), and have those randomly play, then you are most likely looking at a custom filter that can pick the videos for you. I manage/play my videos 1-by-1, so I haven't played with VLC, playlists, etc that may apply to your request
