You can use any animation for your personal usages or for your RU-vid channel logo presentations and there will be no copyright issue. But please avoid using them for any commercial usage or monetisation. This will raise the copyright issue.
This channel is for anyone being familiar or want to be familiar to Green Screen (Chrome Key), so they can use these free logos and elements to create their favourite logos or projects professionally. If you are not familiar to green screen then don't worry. You can contact me by email (greenscreenanimation12@gmail.com) and I will do the first one absolutely free for you.
