I've always wanted to start my own channel where I would like to comment back on other video that I've been watching or listening. Instead of just commenting in the reply box and become 1 of thousands of comments, I want to show the video in my own video while I voice over comment my opinions about whatever it is I just showed my viewers. It's kind of like RayWilliamJohnson but without the comedy and jokes. My question is, how does copyright work when it comes to this? Does it become legal and fine for me to use someone else's video since I am voice overing it with my own content (my own thoughts)? Or does the fact that I use their video make it a copyright infringement issue? What if I don't actually use the video, but I film the video on my screen...then techincally I am no longer using anyone's video because I am recording my own video of my screen? Does that make it alright? I would just like to know and be clear on how to post videos with my own commentary on it and not get copyrighted thus not make any money. I would like to see if I can earn some money on my channel. Thanks.
