This would be a good question to have officially answered by Video Pad, since using any videos I create on YouTube that are monetized require a license.
My audio and video software from other companies that include music fills similar to my Video Pad software, all have licenses allowing product owners to use the music in commercial applications such as YouTube. If the Video Pad music in the software does not allow it to be used within a project I create on Video Pad, that's a really big issue, especially with the cost of the software and upgrades.
