How can I add simple loop effects in a video?

Hi mates! I'm trying to carry out a project consisting of a YouTube channel focused on lo-fi, jazz, piano, chill music, etc.

I want to create videos that incorporate a few animations, for instance: a fire moving and the steam of a coffee... How can I produce these effects? ChatGPT creates the background image (I pay a premium so I use it as well for this), but how can I animate it? Do you think I should use a specific tool to do it quickly?
I'm using Da Vinci, but I just use it to join music and image, so I should learn from almost zero.
Thanks in advance!!!
