Time to make short-form videos for my webapp. How?

So I reached out the content creation phase of my marketing plan involving hook + demo videos. The thing is that I'm not an influencer nor a videographer so I have no idea how to create these or look for inspiration

Any tips or experience from anyone?

PD: I already got my first users through more natural ways (reaching out, friends of friends, relevant communities, etc.). The idea/product is a webapp to share group photos among Android/iOS friends (e.g. after a trip, without depending on WhatsApp or drives)
