I love that you went down a rabbit hole into watching vids! <333

I'd not seen that one yet - it is very well done and the vidder integrated the comics source so smoothly!
I don't think using comic source is horribly common, but I have seen a few vidders do it.
This is an example from a vidder who makes great multifandom stuff. It's DC Comics and not Star Wars though (check out the warning tags on the AO3 post though): https://archiveofourown.org/works/34241545
