I'm primarily a podficcer, but I've been known to vid on occasion as well.
I have a blanket policy for transformative works, so if you'd like to remix something of mine, please do! Especially, if you're another podficcer who would like to record your own version of something I've already podficced. You don't even have to let me know, but I would love it if you did so I can shower you with praise. :)
If you're an author who'd like to know more about why I'm asking you for permission to share a podfic I've made of your work, check out my Dear Author letter over on my DW.
