Yup! I don’t think there’s any other way to get it. I used yt-dlp, grabbed the highest bitrate possible, converted it to the proper framerate, retimed it, and had to re-edit to fit the scene proper since the scene as uploaded to youtube is also slightly edited IIRC. While I was in there doing all that and converting it to mono for the center channel mixing I added a little bit of extra processing to nudge it a LITTLE closer to taste towards 1977 Vader.
Is there a better source available? I honestly didn’t mind that the YouTube source was what it was in this instance since 77 Vader isn’t exactly hi-fi sounding in the first place.
