Just to give you a bump, I'll say I don't know of anything like that. I just started making videos myself, venturing into new territory. I've been wanting to for a long time, but I had the idea fixed in my head that the only alternative was to record the videos myself (or have someone do it for me), plan out the whole thing, make storyboards (maybe), and edit it all together. I recently decided I could use free video clips from online resources like Pixabay, so I've now done three.
What I use is not online and it isn't free. I'm using adobe premiere elements 15, which is now obsolete; the current version is 2020 instead of 15.
Anyway, I'm sure it can be used to make lyric videos but, as I said, it isn't free. I just looked and the current version is about $100 USD. I know it can do a lot more than I've figured out so far. I can barely use it, but I hope to get better.
Don't know if that's helpful to you at all or not, so, for whatever it's worth, that's what I know.
