Moritz: Thank you for your amazingly detailed response. Not only did I get the video done, but learned a helluva lot as well :)
I didn’t intend for anyone to address the list of things I tried, was just hoping to show the path I was going down. It’s truly appreciated that you took the time to point out the issues with each - definitely learned a lot.
