My son is also into art, but only he is interested in working with video. In simple words, design/editing. He is still in my 6th grade, but he has already started to work with video. To begin with, I taught him to record video from the screen and from other programs such as Skype, discord and others using https://www.movavi.com/support/how-to/how-to-record-a-skype-meeting.html . Then I taught him how to trim videos, convert to other formats, and compress videos. Next we went to staple different videos, add music, and now we are learning different effects in Sony Vegas.
