1. I have made video using power director 365 and I produced video in H.264 AVC. I am going to put these videos in a website where I will be selling the videos as a part of an online course. In the license term, I noticed that for commercial purpose, I have to get the license from H.264/MPEG-4 AVC - AVC Patent Portfolio License.
Does that mean, I have to contact the licensor before I start selling the course?
2. If I use the audio from the background audios provided by Powerdirector, do I need to get some special license to use these audios for commercial purpose?
3. In case of any copyright claim from YouTube regarding background music, is there any document that I can use?
