Ask HN: How do you teach a 7 year old visual editing on PC?

Hi all. As stated in the title, I'm planning to teach my 7 year old brother video / image editing. We can't keep these kids from wanting to became a streamer and recording themselves, might as well get something useful from this.

I guess there are too many applications for mobile (heard something called CapCut) but i'd like to do this on a PC. I'm looking for something like Scratch for Premiere / Photoshop. Educational or just tool suggestions are okay, i can learn the tool firsthand if it's easy enough and teach him afterwards. Any suggestions?
