I’ll DM you the wav of the mix so you can mix it into the episode proper, but yeah, you don’t need to ask permission or anything like that, just go ahead and use it! If I put anything out there, it’s automatically fair game for anyone else to transform however they see fit!
Funny story - I tried posting just that scene, as I had it on YouTube, to reddit on Mother’s Day (I hadn’t posted it to r/fanedits yet and thought that morning “hey, this would be kinda funny”) and it got deleted for “not being a fanedit” so just a heads up - trying to post it to reddit might NOT go so well. I never got an explanation on HOW it’s not a restoration according to their rules, either, but I didn’t think it was worth pressing the issue - it almost never is - especially over a single syllable, LOL.
So I’ve received the file you sent me and I’ve managed to use it and importing it into the episode! It feels flawless! Now I’m gonna upload it in Google Drive then make a post on reddit and here maybe if there is enough interest on both sites! You can ask for a link to the episode.
